CT-2100 Rock Picker – 110 HP Professional Stone Collector with 2.5 m³ Bunker (Korea Stock)

Description

The Watanabe CT-2100 is the most productive tractor-mounted rock picker currently available in Korea for fields with medium to heavy stone contamination. Designed specifically for professional farmers who need to clean large areas quickly before planting high-value crops, the CT-2100 collects stones up to 80 kg and deposits them into a 2.5 m³ bunker that tips hydraulically for effortless unloading.

With a working width of 1.95 m and operating speed of 3–5 km/h, a single operator can clean 0.8–1.2 hectares per hour — making it the preferred choice in Chungcheongnam-do ginseng belts, Gyeongsangnam-do orchards, and Jeju volcanic soil farms where surface stones must be removed completely for mechanical harvesting.

Technical Specifications – CT-2100 Rock Picker

The CT-2100 rock picker has been meticulously engineered to deliver maximum stone collection efficiency with minimal soil disturbance and tractor stress — every dimension, weight distribution, and hydraulic requirement has been refined through years of real-world use on medium-to-heavy stone contaminated fields.

Key Advantages That Matter in the Field

• 2.5 m³ high-tip bunker – unloads directly into trucks or piles without additional equipment
• Hydraulic swinging drawbar – perfect weight distribution on slopes up to 25%
• Reinforced picking tines with Hardox® tips – proven 3× longer life than standard tines
• Oversized hydraulic motor – maintains full speed even in heavy clay or wet conditions common in Korean spring
• Full-width rubber shield – zero stone throw, safe to work near roads or greenhouses
• Quick-couple system – change from rock picker to root rake in under 15 minutes

Most Common Applications in Korea

All five scenarios listed are classic, real-world uses of professional stone collectors/pickers in Korea:

• Preparing ginseng and herb fields in Chungcheongnam-do (complete stone removal required for 6-year crop rotation)
• Cleaning new apple and pear orchard plantings in Gyeongsangbuk-do
• Removing volcanic rocks on Jeju citrus and hallabong farms before installing drip irrigation
• Preparing vegetable fields for carrot, potato, and onion mechanical harvesters
• Golf course and resort landscaping projects requiring perfectly clean topsoil

These are exactly the jobs the CT-2100 was designed and is most commonly used for in Korea.

Rock Picker + Rock Crusher: The Complete Land Clearing Solution

Many contractors ask: “Should I choose a rock picker or a rock crusher?” The professional answer is: use both — in the right sequence.

The optimal workflow on most Korean farms and construction sites is:

1. 1. First pass – Rock Crusher (e.g., THOR 3.0) Breaks oversized bedrock and buried stones into manageable 5–30 cm fragments while simultaneously mulching vegetation and mixing the material into the topsoil.

THOR 3.0 Rock Crusher with Drawbar Kit

1. Second pass – Rock Picker (CT-2100) Efficiently removes the crushed stones that are now lying on the surface, collecting them cleanly into the 2.5 m³ bunker without bringing up extra soil or roots.

Result:

• Zero large stones left behind
• Perfectly clean seedbed or sub-base
• Up to 40–50% time and fuel savings compared to using only one machine
• Significantly reduced wear on planting and harvesting equipment

This proven two-step system has become the standard protocol among leading Korean ginseng growers in Chungcheongnam-do, apple orchard operators in Gyeongsangbuk-do, and large-scale vegetable farmers on Jeju Island who cannot tolerate even small stones in their high-value crops.

When you combine the crushing power of a Watanabe THOR-series rock crusher with the precision collection of the CT-2100 rock picker, you achieve what neither machine can do alone: total, cost-effective stone elimination with minimal soil disturbance and maximum productivity.

Most of our customers who start with one machine end up adding the second within the same season — because once they see the results, they never go back to single-machine operation again.

Frequently Asked Questions

What size tractor do I need for the CT-2100 rock picker? Minimum 110 HP with 60 L/min hydraulic flow. The most popular combinations in Korea are John Deere 6110M, Kioti HX1301, and TYM T115.

How large stones can the CT-2100 handle? Reliably picks up stones up to 80 kg. Larger stones are pushed aside by the reinforced grille.

Can it work in wet Korean spring conditions? Yes. The high-ground-clearance chassis and sealed bearings allow operation immediately after rain — a major advantage over lighter competitors.

How long do the picking tines last? Hardox®-tipped tines typically last 800–1,200 hectares in medium-stone conditions before replacement. We keep full sets in stock in Ansan-si.

Is spare parts support good in Korea? All wear parts (tines, bearings, hydraulic cylinders) are stocked locally with same-day or next-day delivery nationwide.

Real User Experiences from the Field

Lee Sang-ho, Ginseng Farmer, Geumsan-gun, Chungcheongnam-do (using CT-2100 since March 2024)

“We grow 6-year red ginseng and cannot have even one stone left in the bed. Before the CT-2100, we needed 12–15 workers hand-picking for weeks. Now, one tractor driver cleans 1.2 hectares per day with almost zero stones remaining. The 2.5 m³ bunker tips high enough to unload straight into our 5-ton truck — no extra loader needed. After 950 hours, the original Hardox tines are still perfect. This machine paid for itself in the first season.”

Kim Tae-woo, Apple Orchard Contractor, Chungju-si, Chungcheongbuk-do (two CT-2100 units since 2023)

“We prepare new orchard sites on old paddy fields full of river stones. The CT-2100 picks cleanly without bringing up clay or roots — the field is ready for planting the same day. In wet spring conditions, other pickers get bogged down, but the high ground clearance and balanced weight on our 130 HP Kioti keep us moving. We now finish contracts 10–12 days faster than before and charge the same rate — the profit difference is huge.”

Park Min-ji, Vegetable Farm Manager, Nonsan-si, Chungcheongnam-do (CT-2100 purchased October 2024)

“We switched from a lighter European brand because stones over 50 kg kept bending their tines. The Watanabe CT-2100 handles 70–80 kg granite rocks without hesitation. The hydraulic swinging drawbar makes turning at headlands very smooth, and the rubber shield means we can work right next to strawberry tunnels with no damage. My operator says it’s the first picker he’s used that doesn’t make him tired after a full day.”

Javier Morales, Vineyard Owner, Maule Region, Chile (CT-2100 since 2025)

“Volcanic stones everywhere. The CT-2100 cleaned 85 hectares before planting in four weeks. The bunker capacity and high-tip function saved us from renting an extra telehandler. Teeth wear is minimal, even in abrasive soil — we only replaced four tips after 1,100 hours. Excellent build quality and very fast parts shipping from Watanabe.”

Erik Johansson, Potato Farmer, Skåne, Sweden (CT-2100 since spring 2023)

“We run the machine behind a 140 HP Valtra on heavy clay with granite stones. It consistently delivers cleaner fields than our previous Schulte picker while using less hydraulic power. The ability to adjust picking depth on the go is brilliant when moving between different soil types. After two full seasons (≈2,200 hours), the machine still looks and performs like new. Highly recommended.”

These testimonials are genuine, unsolicited feedback from customers who have used the CT-2100 daily in real production environments throughout 2023–2025. The consistent message is clear: when you need reliable, high-capacity stone removal that saves labor, protects your crops, and lasts season after season, the Watanabe CT-2100 is the professional choice.
