THOR FLM Stone Crusher – Silviculture & Land Opening, 230 HP
The THOR FLM is the most versatile model in the THOR line — purpose-built for silviculture and land opening where both stumps, roots, and rock must be processed in the same pass. Two interchangeable hammer configurations adapt to hard rock or soft vegetation material.
230 HP + CVT transmission required. 1000 RPM PTO. 1.68 m working width. Narrow enough for forestry access tracks where wider THOR models cannot operate.
Where Rock and Vegetation Meet — The THOR Built for Forestry Work
The THOR 2.4 and THOR 3.0 are rock crushers. They are optimised for stone — grinding boulders and surface rock into aggregate with maximum efficiency on cleared agricultural land. The Watanabe THOR FLM is a different machine for a different task. It is described by Watanabe as "the most versatile model within the Thor product line," engineered specifically for silviculture and land opening — the conditions where surface stones and embedded rock exist alongside stumps, roots, brush, and other woody vegetation material that must all be processed in the same clearing operation.
The defining characteristics of the THOR FLM follow directly from this application:
▶ Narrower — 1.68 m
Where the THOR 2.4 and 3.0 sweep wide to cover open agricultural terrain, the THOR FLM's 1.68-meter working width fits forestry access tracks, plantation corridors, and the tight working spaces of post-forestry land clearing where wider machines cannot maneuver.
▶ Two Hammer Configurations
One hammer type is optimised for hard rock — carbide-tipped and geometry designed for maximum rock fragmentation impact. The second is optimised for soft materials — stumps, roots, brush, and green wood — where a different blade angle and edge profile produces clean cutting rather than hard impact. Switching between configurations allows the operator to match hammer type to the dominant material in each working area.
▶ CVT + Ultra-Low Speed
Working speed as low as 0.6 km/h — a walking pace — is essential when the rotor encounters dense embedded material. CVT (Continuously Variable Transmission) on the tractor allows the operator to reduce speed smoothly to any point between 0.6 and 2.5 km/h without gear-step jumps that would disrupt the rotor's engagement with the material being processed.
The result is a machine that covers the clearing operation that falls between a forestry mulcher and a rock crusher — a category that field operations in post-forestry Korean highland land conversion encounter frequently. Most sites in Korea's forest-to-agriculture conversion zones have both embedded rock and organic material (stumps, roots, brush) in proportions that vary across the same field — the THOR FLM handles both from the same machine, with a hammer change between zones where the dominant material type shifts.

ⓘ All data from Watanabe official partner site (soilstabilizermachine.com). CVT = Continuously Variable Transmission — this is a mandatory tractor specification, not an optional feature. A tractor without CVT cannot maintain the 0.6–2.5 km/h working speed range that the THOR FLM requires for safe and effective operation. Verify your tractor's transmission type before enquiring.
⚠ CVT Tractor is Mandatory — Not Optional
The THOR FLM's minimum working speed of 0.6 km/h — approximately walking pace — cannot be achieved reliably with a standard gear-step tractor without significant risk of rotor overload and engine stall when the machine encounters dense material. CVT allows smooth, stepless speed reduction to any point between 0.6 and 2.5 km/h in real time as material density changes. Korean CVT-equipped tractor models in the 230 HP range include the John Deere 6R 230 (AutoPowr transmission), Fendt 724 Vario, New Holland T7.230 (AutoCommand), and Valtra T174 SmartTouch. Confirm your tractor's transmission type with its specification sheet or dealer before ordering.

How the THOR FLM Works — Impact Processing of Mixed Material
The Rotor — High-Speed Impact at Ultra-Low Forward Speed
The THOR FLM's operating principle is the same as all THOR models: a horizontal rotor driven by the tractor PTO at 1000 RPM sweeps the working zone, and the hammers mounted on the rotor strike the material — rock fragments, stumps, roots, brush — at high velocity, fracturing or shredding it into smaller pieces that are dispersed or left on the ground surface as mulch. The kinetic energy of the impact is what does the work; the rotor speed determines the energy available per hammer strike.
What distinguishes the THOR FLM from the rock-specific THOR models is that the rotor and hammers are designed to handle the broader range of material properties encountered in silviculture and land opening — from hard granite surface rock that requires brittle fracture impact, to soft green wood that requires shear-cutting action, to dry stumps that require a combination of both. The two interchangeable hammer configurations address these different material properties by changing the hammer geometry and edge specification between working zones.
Two Hammer Configurations — Adapting to the Material
The first hammer configuration is optimised for hard rock and stone. These hammers use carbide-tipped impact faces at an angle that maximises the fracturing energy delivered to the rock surface on contact. The geometry is similar to the hammer specification on the THOR 2.4 and THOR 3.0 — designed for the compressive fracture mode of hard brittle materials. This configuration is appropriate when working through areas where embedded rock and surface boulders dominate, with minimal organic material.
The second hammer configuration is optimised for soft materials — stumps, roots, brush, and green or dry wood. These hammers use a different blade angle and edge profile that produces a shear-cutting action on fibrous organic material rather than an impact-fracture action. When the rotor encounters a large stump root, this configuration shreds the fibrous wood into chips rather than bouncing off it — producing a more complete reduction of the organic material in fewer passes.
In practice, most silviculture and land opening sites in Korea have a spatial distribution of rock and organic material across the field — areas of higher stone density near rock outcrops and areas of heavier organic material in the zones where root systems are denser. The operator can change hammer configuration at the field margins between these zones, or select the configuration that best matches the dominant material type across the majority of the working area and accept reduced efficiency on the minority material type.
CVT — Matching Speed to Material Density in Real Time
The requirement for CVT (Continuously Variable Transmission) on the tractor is the most operationally critical specification of the THOR FLM — and the most commonly misunderstood by buyers approaching it from a standard THOR 2.4/3.0 background.
At 0.6 km/h — the minimum working speed — the rotor is processing a high volume of material per unit of forward travel. This is the appropriate speed when the operator encounters a dense stump cluster, a rock concentration, or a particularly resistant embedded root system. If the tractor were equipped with a standard mechanical gearbox, the lowest available creep gear would likely produce a speed above 0.6 km/h at the required engine RPM to maintain PTO speed — and more importantly, reducing speed below a gear step requires either stopping and changing down (losing momentum and disrupting the rotor engagement) or allowing the clutch to partially slip (generating heat and wear).
CVT allows the operator to reduce ground speed smoothly and continuously while the engine and PTO maintain their required operating speeds. The operator can slow from 2.0 km/h to 0.6 km/h as they approach a dense material zone without any gear change or rotor speed disruption — the CVT continuously varies the transmission ratio to match the selected ground speed while the engine operates at its optimal load point. When the dense zone is cleared, speed can be increased smoothly back to 2.0 km/h for open ground. This continuous real-time speed adaptation is what makes the THOR FLM effective in the variable-density material environment of silviculture and land opening work.
What Happens to the Processed Material
Rock fragments are shattered into small pieces — typically less than 10 cm after a pass — that remain on the ground surface or are dispersed across the working zone. These fragments compact into the soil profile over the subsequent tillage operations, or are further reduced in a follow-up pass if sizes remain above the target for the next cultivation step. The rock processing result of the THOR FLM is similar to that of the THOR 2.4 on comparable rock sizes, though the narrower working width means more passes are required to cover the same area.
Wood material — stumps, roots, brush — is reduced to chips and shreds that remain on the surface as organic mulch. These decompose over the following months or years, contributing organic matter to the soil profile. For sites where the organic material load is high, the mulch layer can be incorporated into the soil by rotary cultivation (with a machine such as the PSW-3200 Rotavator) after the THOR FLM clearing pass, accelerating decomposition and preparing a seedbed in the same season as the clearing operation.
Why the THOR FLM Is the Right Machine for Silviculture Work
■ Handles Both Rock and Vegetation
The THOR 2.4 and 3.0 are rock-specific; a forestry mulcher is vegetation-specific. The THOR FLM with two interchangeable hammer configurations covers both material types from one machine. Post-forestry sites in Korea's highland conversion zones regularly present both material types in adjacent working zones — the THOR FLM processes both without machine changes.
■ 1.68 m — Forestry Access Width
Korea's highland forestry access tracks and plantation corridors are typically 3–4 meters wide — adequate for a tractor with a 2.48-meter total-width (THOR FLM) implement, but not for a 3-meter wide THOR 3.0. The THOR FLM's narrower working width allows it to enter and work within the access corridors that define the working geometry of plantation and managed forest land clearing.
■ CVT Enables Precision Speed Control
The 0.6–2.5 km/h speed range — achievable only with CVT — gives the operator precise real-time control over material processing rate. Slow through dense embedded material; fast over cleared zones. This continuous adaptation produces a more consistent processing result than fixed-gear creep operation, and protects the rotor and drive system from overload spikes that occur when hard material is encountered at above-optimal speed.
■ No Separate Stump Removal Step
Conventional post-forestry land preparation requires separate stump pulling or grinding, root raking, and stone clearance operations — three machine types and three separate field passes. The THOR FLM with the vegetation hammer configuration reduces stumps and roots to ground-level chips in the same pass as rock processing, eliminating the dedicated stump removal step and the machine mobilisation costs associated with it.
■ Organic Mulch — Soil Improvement
The wood chips and vegetation shreds produced by the THOR FLM's vegetation hammer operation constitute a significant organic matter input to the cleared land. Unlike stump removal and disposal — which removes this organic material from the site — THOR FLM processing leaves the organic content in place, where it decomposes into the soil profile and contributes to the long-term soil organic matter balance of the newly opened agricultural land.
Where the THOR FLM Gets Used in Korea
🌿 Post-Forestry Land Conversion — Highland Agriculture Opening
Korea's highland zones — particularly Gangwon-do and the central mountain belt of North Gyeongsang and North Chungcheong — have significant areas of former plantation forestry that are being progressively retired and assessed for conversion to agricultural use. These are primarily Japanese cedar (삼나무, Cryptomeria japonica) and pine (소나무) plantations that reached rotation age and whose economics as timber have declined relative to the land's potential value as highland agricultural production area.
After the standing timber is harvested, the land presents the characteristic mix of post-forestry challenges: stumps at ground level, a mat of surface roots extending from each stump, residual slash (branches and tops left after harvest), and the exposed surface rock and boulders that were previously concealed by the forest floor material. A conventional stump grinder can address the stumps; a rock crusher can address the stone; but neither addresses both. The THOR FLM with its two hammer configurations processes all of these material types in a coordinated clearing sequence — vegetation hammer for the stump-and-root zones, rock hammer for the stone-concentration zones — without requiring a second machine type.
🏙 Plantation Management and Silvicultural Operations
In active commercial forestry in Korea — primarily the managed softwood plantations in Gangwon-do and Gyeongbuk — periodic silvicultural operations require access track maintenance, understory clearing, and boundary management. Access tracks in plantation forestry accumulate rock debris, blow-down timber, and invasive vegetation over the years between clearing cycles. The THOR FLM's 1.68-meter working width — matching standard forestry track widths — allows it to operate within active plantation infrastructure without damage to standing crop trees, processing track obstructions and maintaining clear access for harvest and management operations.
The vegetation hammer configuration is particularly suited to the understory clearing application, where the material is predominantly woody scrub and brush rather than rock. Korean forest management regulations increasingly require clearing of the high-fire-risk understory in managed plantations — particularly the dense flammable brush layer that develops in neglected plantation corridors. The THOR FLM with vegetation hammer configuration processes this material efficiently without damaging the plantation trees above.
🍋 Mixed Rocky-Vegetated Land Opening for Large Farms
Some of Korea's most productive highland potato and vegetable growing areas were themselves originally forested land that was cleared for agricultural use over the past 40–50 years. Farms that are now expanding into adjacent uncultivated land — former grazing land that has reverted to scrub, or marginal forest margins that were never formally cultivated — encounter the same mixed rock-and-vegetation challenge as post-forestry conversion sites, but on a smaller scale and with a higher proportion of shrub vegetation relative to timber-grade stumps.
For these expansion clearing operations, the THOR FLM's combination of rock and vegetation capability in one machine, with narrow enough width to work in the irregular margins of existing agricultural fields, makes it the practical clearing tool. A separate forestry mulcher (for the shrub vegetation) and a rock crusher (for the stone) would require two separate passes with two machine setups; the THOR FLM handles both from one machine, with a hammer change when the dominant material type requires it.
Which THOR Is Right for Your Operation
The three THOR models serve different primary applications. Use the table below to identify the right match — the most common mistake is selecting the THOR FLM when the THOR 2.4 or 3.0 is the right tool, or vice versa:
| Your Situation | Best THOR | Why |
|---|---|---|
| Open agricultural land, surface rocks only, 180 HP tractor | ثور 2.4 | Lower power, wider than FLM, rock-only application |
| Open land, heavy boulder load, maximum rock crushing, 230+ HP | ثور 3.0 | Maximum rock capacity and working width for open land |
| Post-forestry land, mixed rock + stumps/roots, 230 HP CVT | THOR FLM | Two hammer types, narrow for forestry access, CVT speed control |
| Plantation access tracks, understory clearing (no significant rock) | THOR FLM | Vegetation hammer, narrow width for track work |
| Open farmland, large rocks, 300 HP tractor, highest throughput | BlackBird + THOR 3.0 | Rake-and-crush system for maximum open-land throughput |
⚠ If your tractor does not have CVT, the THOR 2.4 or THOR 3.0 is your THOR
The THOR 2.4 and THOR 3.0 can both operate effectively with standard gear-step tractors in their respective power classes. The THOR FLM's CVT requirement is non-negotiable. If your application is post-forestry land clearing but your tractor is a standard gear-step model, discuss the specific material conditions with us — in some cases, the THOR 3.0 with careful speed management can handle mixed material, depending on the stump size and density.
The Full Watanabe Land Clearing Product Family
The THOR FLM operates within a complete Watanabe land clearance and soil preparation range. Here is where each product fits in the typical sequence for large-scale post-forestry land opening:
THOR FLM — Mixed Material Clearing YOU ARE HERE
Process stumps, roots, brush, and surface rock simultaneously. Two hammer configurations adapt to material type. 1.68 m width for forestry access corridors.
EP-EW-4000 Rock Rake or BlackBird Rock Rake
Surface stone windrow formation after THOR FLM clearing pass. EW-4000 for smaller areas; BlackBird for large open fields after forestry corridors are cleared.
THOR 3.0 — Residual Rock Processing
Crush stone windrows formed by the rake into aggregate. Or couple the ثور 3.0 directly behind the BlackBird on the rear hitch for simultaneous rake-and-crush on open cleared land.
Primary Tillage — PSW-3200 Rotavator
Once the land is cleared and surface stone is processed, primary tillage prepares the seedbed for the first agricultural crop. The PSW-3200 (3.0–3.6 m, 140 HP) incorporates remaining surface material and builds the cultivation profile.
Watanabe THOR Engineering — Built for Heavy Silviculture Work
The THOR product line grew out of Watanabe's experience in the Brazilian agricultural land opening sector — particularly in the cerrado and Amazon transition zones where large areas of native vegetation are progressively cleared for agricultural use. The conditions in these Brazilian zones — embedded rock, deep root systems, hard laterite soil, and thick woody vegetation — are among the most demanding land clearing environments in the world, and they are the design reference that shaped the THOR series' robustness specification.
The THOR FLM's particular design challenge is the two-material processing requirement — the rotor and drive system must handle the sharp instantaneous load spikes of hard rock impact and the sustained, high-torque drag of fibrous stump and root processing in the same operating session. The drive system specification, rotor shaft dimensioning, and hammer mounting geometry all reflect this dual-demand requirement. The CVT requirement is not an add-on specification — it is fundamental to protecting the drive system from the overload spikes that would occur if the tractor attempted creep-speed operation in dense material on a standard gear-step transmission.
✓ CVT Compatibility Verified
We confirm CVT availability on your specific tractor model before the order is placed. Not all tractors marketed as "variable speed" have true CVT — stepless transmission systems vary significantly in their low-speed capability. We review your tractor specification sheet to confirm suitability.
✓ Hammer Configuration Guidance
We provide guidance on which hammer configuration to start with based on your site's dominant material type — rock-heavy or vegetation-heavy — and how to read the rotor load indicators to decide when to switch configurations on a mixed site.
✓ Wear Parts Supply
Both hammer configurations are wear-limited items — hard rock operation wears the carbide tips; dense stump processing wears the cutting edges. We maintain supply chain contact with Watanabe Brazil for replacement hammer sets, with typical order-to-Korea delivery timelines provided at purchase.
Frequently Asked Questions – THOR FLM Stone Crusher
What does "FLM" stand for?
FLM is Watanabe's designation for the forestry and land-opening variant of the THOR product line. In Portuguese, the application is described as silvicultura (silviculture/forestry) and abertura de áreas (land opening/clearing) — the two primary use cases the FLM was designed for. The designation distinguishes this model from the agricultural rock-specific THOR 2.4 and THOR 3.0, which share the THOR name but serve a different primary application.
Why is CVT mandatory — can I use a standard tractor with a very low creep gear?
Standard gear-step tractors have discrete gear steps — moving from one gear to the next produces an abrupt change in ground speed. In dense material (a large stump root, a rock cluster), the operator may need to reduce speed below the lowest available creep gear, at which point the options are: stop and reverse (disrupting the clearing sequence), or allow the clutch to slip at the current gear (generating heat and accelerating clutch wear). CVT allows continuous speed reduction to 0.6 km/h without either compromise. Additionally, the low-speed torque multiplication of CVT at the ground wheel provides additional traction and momentum in dense material situations that standard gear-step tractors cannot replicate at equivalent ground speed. We do not recommend the THOR FLM with non-CVT tractors — the risk of rotor overload and drive train damage in demanding material is significant.
When should I use the rock hammer vs the vegetation hammer?
Use the rock hammer when the working zone is dominated by embedded stone, boulders, and minimal organic material — such as the rocky outcrops and stone-concentration zones common on Korean highland clearing sites. Use the vegetation hammer when working through stump-dense zones, brush-covered areas, or sections with heavy root mat where organic material significantly outnumbers rock. On a typical mixed site, you may change configurations once or twice during the day as you move between material-type zones. With experience, operators develop a feel for the rotor load sound and behavior that indicates when a hammer change would improve processing quality on the current material.
Can the THOR FLM process large stumps?
The THOR FLM with the vegetation hammer is designed for stump processing at ground level — stumps that have been cut flush with the ground surface after timber harvest. It is most effective on stumps up to approximately 30–40 cm diameter. For larger stumps — plantation trees of above 30 cm trunk diameter at cutting height — the THOR FLM may require multiple passes over the same stump, or the stump may need prior reduction by a dedicated stump grinder or excavator before the THOR FLM pass. Provide information on your expected stump diameters when contacting us for a suitability assessment.
How does the THOR FLM compare to a dedicated forestry mulcher?
A dedicated forestry mulcher is optimised for vegetation — brush, scrub, and young trees — typically using fixed or swinging blades rather than impact hammers, and is highly effective on biomass material but typically cannot process embedded rock without significant blade damage. The THOR FLM occupies the overlap zone: it handles both vegetation (with the vegetation hammer) and rock (with the rock hammer), making it more versatile on mixed sites at the cost of being less optimised than a dedicated mulcher on pure-vegetation sites. For sites with negligible rock content, a forestry mulcher may produce cleaner processing results. For sites with significant rock content mixed through the organic material — the typical post-forestry highland Korean clearing site — the THOR FLM's dual capability is more practical than running a mulcher (that would be damaged by rock) and a separate THOR rock crusher.
What is the daily area coverage for the THOR FLM?
At 2.5 km/h maximum speed and 1.68 m working width, the theoretical maximum coverage rate is approximately 0.42 ha/h. In practical post-forestry clearing, where the machine frequently slows to 0.6–1.0 km/h on dense material and requires headland turns at corridor ends, daily coverage of 1.5–2.5 hectares is realistic depending on material density and site layout. Heavily stumped sites with large root systems will produce lower daily output than lightly stumped or brush-dominated sites. The THOR FLM is not a high-throughput machine — it is a precision-clearing machine for demanding mixed-material sites where throughput is constrained by the material rather than by machine capability.
Is the THOR FLM suitable for slope work in Korean highland forestry?
The THOR FLM at 2,300 Kg is lighter than the THOR 3.0 (which is heavier) and the same power class as the THOR 2.4, allowing it to work on moderate slopes. Korean highland forestry generally operates on slopes of 15–25%, which is within the range for careful tractor operation with a rear-mounted implement. Working up-and-down slope (not across the face) is the safe approach on steeper terrain, and the CVT tractor's smooth speed control is an advantage on slope work where abrupt gear changes create stability risks. For slopes above approximately 20%, discuss your specific site conditions and planned working direction with us before confirming the THOR FLM for the application.
Korean CVT tractor models — which are compatible?
CVT-equipped tractors in the 230 HP class available in the Korean market include: John Deere 6R 230 (AutoPowr or DirectDrive transmission), Fendt 724 Vario (Vario CVT), New Holland T7.230 (AutoCommand transmission), Valtra T174 (SmartTouch CVT), and CLAAS Arion 650 (CMATIC CVT). Note that the domestic Korean tractor brands (Daedong, LS, TYM) primarily manufacture gear-step and power shuttle transmissions in the 200+ HP class — most do not currently offer true CVT in this power range. If your existing fleet consists entirely of Korean domestic-brand tractors, confirm with the dealer whether any CVT option is available in the 230 HP range before enquiring about the THOR FLM.
What Our Customers Say
Im Seong-tae — Post-Forestry Land Development Contractor, Gangwon-do (2024)
★★★★★
"We cleared 35 hectares of former cedar plantation land in Gangwon-do for conversion to potato production — mixed stone and stump content throughout. The THOR FLM was the right machine because we had both problems on the same site. The Korea Watanabe team was very clear about the CVT requirement before we purchased — we had a John Deere 6R 230 AutoPowr in the fleet which met the specification. Working at 0.8–1.2 km/h on the stump-dense sections and 2.0 km/h on the more open rocky sections, we covered about 2 hectares per day. The vegetation hammer handled the cedar stumps cleanly; the rock hammer processed the surface granite. Land was ready for tillage within 25 working days."
Bae Gwang-jin — Plantation Forestry Manager, North Gyeongsang (2024–2025)
★★★★★
"We manage approximately 800 hectares of mixed conifer plantation and use the THOR FLM for access track maintenance and periodic understory clearing in the fire-risk zones. The 1.68-meter working width is exactly right for our plantation track standard — we work within the track without any risk to the adjacent standing crop trees. Two seasons of regular use: vegetation hammer for the understory work, rock hammer for the track surface maintenance where granite surface stones accumulate. No rotor or drive issues. The CVT on our Fendt 724 Vario is the specific reason this machine works so well in the track environment where we constantly vary speed around obstacles."
Song Min-ho — Highland Farm Expansion Project, Inje-gun, Gangwon-do (spring 2025)
★★★★★
"We added 22 hectares of former scrubland adjacent to our existing potato fields — mixed alder scrub and surface rock on volcanic highland soil. The THOR FLM on our New Holland T7.230 AutoCommand cleared the vegetation and surface rock in 12 working days. The vegetation hammer handled the alder root systems well; we switched to the rock hammer on the sections with higher stone density near the former field boundary. The Korea team's pre-sale material assessment was accurate — they reviewed photos I sent and correctly predicted the hammer change zones on our site."
Hwang Jae-won — Agricultural Land Development Contractor, Chuncheon region (2025)
★★★★★
"I specifically chose the THOR FLM over the THOR 3.0 for forestry work because of the hammer flexibility — the THOR 3.0 is a rock machine and the vegetation hammer on the FLM is what lets me take stump-heavy contracts that a rock-only crusher can't handle without rotor damage. My FLM is on a John Deere 6R 250 DirectDrive — the CVT requirement was the deciding factor for which tractor I paired it with. Two seasons, multiple sites, no rotor issues. The narrower width means more passes to cover the same area than a THOR 3.0 would on open ground, but for the forestry work environment that width is the correct specification — you can't use a wider machine in plantation corridors anyway."
Oh Jae-hoon — Forest-to-Agriculture Conversion Contractor, Gyeongbuk highlands (2024)
★★★★★
"I was running a separate forestry mulcher and a THOR 2.4 on two different tractors for post-forestry clearing work — one machine for the vegetation, one for the rock, two operators, two fuel bills. The THOR FLM consolidated those into one machine and one operator. Not every post-forestry site needs both configurations equally, but on the mixed sites in Gyeongbuk where rock and organic material are distributed unpredictably across the same clearing area, having both available from one machine with a 30-minute hammer change is considerably more practical than logistics of two machines. The Korea Watanabe team helped me work through the economics before I switched — the numbers were clear."
Shin Dong-woo — Livestock and Forestry Farm, Yanggu-gun, Gangwon-do (spring 2025)
★★★★★
"Our farm has a mix of agricultural land and managed forest area. We use the THOR FLM for three different tasks across the season: post-harvest timber track clearing in February–March before spring agricultural work begins, summer fire-risk understory clearing in the plantation zones, and autumn land expansion clearing on scrubby margins adjacent to our cattle pasture. The three different applications all work within the THOR FLM's capability — vegetation hammer for the understory and scrub work, rock hammer for the track surface maintenance. One machine, three applications, one CVT Fendt tractor. Good combination for a diversified farm operation."
