The labour required to manually dig 1 hectare of potatoes in Gangwon-do highland conditions \u2014 typically 25\u201340 person-hours per hectare depending on yield and stone content \u2014 can be replaced by 1.5\u20133 tractor-hours of mechanical digger operation. For farms operating in a planting-to-harvest window already constrained by altitude and frost calendar, the time saving from mechanical harvest is as important as the labour saving.<\/p>\n<p>The Watanabe EP-AWB potato digger series covers four configurations from the 2-row mounted EP-AWB-1600 through to the 4-row trailed EP-AWB-3200 and the in-field packaging EP-CWB-2L Big Bag Harvester. Each configuration has a specific application range \u2014 farm scale, field geometry, row count, and supply chain destination all influence which configuration delivers the best result for a specific Korean operation. Buying the wrong configuration means buying a machine that underperforms relative to your actual operational requirements, even if the specifications appear comparable on paper.<\/p>\n<p>This guide explains how the Watanabe potato digger range is structured, what determines the right configuration for different Korean highland operations, and how to match your row spacing \u2014 set at the PSW-3200 rotavator stage \u2014 to the digger that harvests it efficiently six months later.<\/p>\n<p><!-- SECTION 1: THE CORE DECISION --><\/p>\n<h2 style=\"font-size: clamp(20px,2.8vw+10px,30px); color: #1a1a1a; border-left: 5px solid #f07c00; padding-left: 16px; margin: 48px 0 20px 0; line-height: 1.3;\">The Core Decision \u2014 Mounted or Trailed, and Why It Matters<\/h2>\n<p><img decoding=\"async\" style=\"width: 100%; height: auto; display: block; border-radius: 6px; margin: 20px 0 28px 0;\" title=\"EP-AWB Potato Digger \u2014 Mounted Configuration\" src=\"https:\/\/rock-crusher-tractor.com\/wp-content\/uploads\/2026\/05\/Potato-Harvest-1.webp\" alt=\"Watanabe EP-AWB potato digger harvesting Korean highland potatoes \u2014 vibrating web separator, mounted configuration\" \/><\/p>\n<p>The fundamental difference between mounted and trailed potato digger configurations is where the harvested potato goes after the lifting and separation process:<\/p>\n<p><strong>Mounted digger (EP-AWB-1600):<\/strong> The machine mounts on the tractor&#8217;s rear three-point hitch. After the vibrating web separator removes soil from the lifted potatoes, the clean tubers are directed to one of three discharge options \u2014 side windrow (Kit A), rear elevator to following collection cart (Kit B), or transfer elevator to trailer (Kit C). The tractor, digger, and output system move as a single unit through the field. This configuration is compact, manoeuvrable in shorter field lengths, and suited to smaller operations where a dedicated following cart or truck is not always available.<\/p>\n<p><strong>Trailed digger (EP-AWB Trailed series, EP-AWB-3200):<\/strong> The machine is towed behind the tractor on its own wheels. Trailed configurations are typically higher-capacity \u2014 the EP-AWB-3200 harvests 4 rows simultaneously \u2014 and may include integrated bunker or tank capacity that allows the machine to operate independently for longer periods before requiring a discharge stop. Trailed diggers are suited to larger fields where the higher initial capital cost is justified by throughput gains, and where field geometry allows the wider turning radius of a tractor-plus-trailer combination at headlands.<\/p>\n<div style=\"overflow-x: auto; margin: 24px 0;\">\n<table style=\"width: 100%; border-collapse: collapse; font-size: clamp(12px,1.3vw+8px,14px); min-width: 480px;\">\n<thead>\n<tr>\n<th style=\"background: #1a1a1a; color: #fff; padding: 10px 12px; text-align: left; border-right: 1px solid #333;\">Factor<\/th>\n<th style=\"background: #c86000; color: #fff; padding: 10px 12px; text-align: center; border-right: 1px solid #a05000;\">Mounted (EP-AWB-1600)<\/th>\n<th style=\"background: #2e5fa3; color: #fff; padding: 10px 12px; text-align: center;\">Trailed (EP-AWB-3200)<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr style=\"background: #fff;\">\n<td style=\"padding: 8px 12px; border-bottom: 1px solid #eee; font-weight: bold;\">Rows harvested<\/td>\n<td style=\"padding: 8px 12px; border-bottom: 1px solid #eee; text-align: center;\">2 rows<\/td>\n<td style=\"padding: 8px 12px; border-bottom: 1px solid #eee; text-align: center; font-weight: bold;\">4 rows<\/td>\n<\/tr>\n<tr style=\"background: #f8f8f8;\">\n<td style=\"padding: 8px 12px; border-bottom: 1px solid #eee; font-weight: bold;\">Min. tractor HP<\/td>\n<td style=\"padding: 8px 12px; border-bottom: 1px solid #eee; text-align: center; font-weight: bold; color: #c86000;\">75 HP<\/td>\n<td style=\"padding: 8px 12px; border-bottom: 1px solid #eee; text-align: center;\">110+ HP<\/td>\n<\/tr>\n<tr style=\"background: #fff;\">\n<td style=\"padding: 8px 12px; border-bottom: 1px solid #eee; font-weight: bold;\">Linkage<\/td>\n<td style=\"padding: 8px 12px; border-bottom: 1px solid #eee; text-align: center;\">Cat. 2 (rear hitch)<\/td>\n<td style=\"padding: 8px 12px; border-bottom: 1px solid #eee; text-align: center;\">Drawbar tow<\/td>\n<\/tr>\n<tr style=\"background: #f8f8f8;\">\n<td style=\"padding: 8px 12px; border-bottom: 1px solid #eee; font-weight: bold;\">Headland turning<\/td>\n<td style=\"padding: 8px 12px; border-bottom: 1px solid #eee; text-align: center; font-weight: bold; color: #c86000;\">Tight \u2014 suitable for short rows<\/td>\n<td style=\"padding: 8px 12px; border-bottom: 1px solid #eee; text-align: center;\">Wider radius \u2014 needs longer rows<\/td>\n<\/tr>\n<tr style=\"background: #fff;\">\n<td style=\"padding: 8px 12px; border-bottom: 1px solid #eee; font-weight: bold;\">Terrain flexibility<\/td>\n<td style=\"padding: 8px 12px; border-bottom: 1px solid #eee; text-align: center; font-weight: bold; color: #c86000;\">High \u2014 slopes, narrow terraces<\/td>\n<td style=\"padding: 8px 12px; border-bottom: 1px solid #eee; text-align: center;\">Lower \u2014 flatter, larger fields<\/td>\n<\/tr>\n<tr style=\"background: #f8f8f8;\">\n<td style=\"padding: 8px 12px; border-bottom: 1px solid #eee; font-weight: bold;\">Daily coverage<\/td>\n<td style=\"padding: 8px 12px; border-bottom: 1px solid #eee; text-align: center;\">0.5\u20131.2 ha\/h (2-row)<\/td>\n<td style=\"padding: 8px 12px; border-bottom: 1px solid #eee; text-align: center; font-weight: bold;\">1.0\u20132.0 ha\/h (4-row)<\/td>\n<\/tr>\n<tr style=\"background: #fff;\">\n<td style=\"padding: 8px 12px;\">Best scale<\/td>\n<td style=\"padding: 8px 12px; text-align: center;\">2\u201315 ha operations<\/td>\n<td style=\"padding: 8px 12px; text-align: center; font-weight: bold; color: #2e5fa3;\">15+ ha operations<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p><!-- SECTION 2: EP-AWB-1600 IN DETAIL --><\/p>\n<h2 style=\"font-size: clamp(20px,2.8vw+10px,30px); color: #1a1a1a; border-left: 5px solid #f07c00; padding-left: 16px; margin: 48px 0 20px 0; line-height: 1.3;\">EP-AWB-1600 Mounted Potato Digger \u2014 The Korean Highland Standard<\/h2>\n<p><img decoding=\"async\" style=\"width: 100%; height: auto; display: block; border-radius: 6px; margin: 20px 0 28px 0;\" title=\"EP-AWB-1600 Structural Detail\" src=\"https:\/\/rock-crusher-tractor.com\/wp-content\/uploads\/2026\/05\/Potato-Harvest-Structure-1.webp\" alt=\"EP-AWB-1600 potato digger structure \u2014 lifting shares, vibrating web separator, soil separation mechanism for Korean potato harvest\" \/><\/p>\n<p>The <a style=\"color: #f07c00; text-decoration: none; font-weight: bold;\" href=\"https:\/\/rock-crusher-tractor.com\/ko\/product\/ep-awb-1600-potato-digger-2-row-75hp\/\">EP-AWB-1600 potato digger<\/a> is a 2-row mounted implement (Cat. 2 three-point hitch, 75 HP minimum PTO) \u2014 the standard configuration for Korean highland potato farms in the 2\u201315 ha operational scale range. Its adoption by the majority of Korean commercial highland potato operations reflects several practical advantages that align with the specific field conditions and farm logistics of Gangwon-do potato country:<\/p>\n<h3 style=\"font-size: clamp(16px,2vw+9px,22px); color: #1a1a1a; margin: 28px 0 14px 0;\">How the EP-AWB-1600 Works<\/h3>\n<p>The machine&#8217;s two lifting shares travel beneath the two planted rows, angled to penetrate below the tuber zone at 15\u201320 cm depth. As the tractor advances, the shares lift the complete ridge \u2014 soil, tubers, and any residual surface material \u2014 onto the vibrating web conveyor above. The web conveyor&#8217;s reciprocating motion separates loose soil and small particles (which fall through the web and back to the field) from the tubers (which are too large to fall through the web mesh and ride forward along the conveyor). By the time the tubers reach the rear of the conveyor, the majority of adhering soil has been separated by vibration \u2014 producing clean, soil-free tubers ready for discharge.<\/p>\n<p>The vibrating web separation is the critical quality step: tubers with excessive adhering soil at harvest create problems at grading and packaging, and in long-term storage, soil pockets between tubers promote moisture accumulation and disease spread. The web&#8217;s vibration rate and amplitude determine the completeness of soil separation \u2014 optimised for the specific soil density and moisture conditions of Korean highland granite-derived soils.<\/p>\n<h3 style=\"font-size: clamp(16px,2vw+9px,22px); color: #1a1a1a; margin: 32px 0 14px 0;\">Three Output Kits \u2014 Matching Harvest Logistics<\/h3>\n<p>The EP-AWB-1600 is available with three different output configuration kits, each suited to a different harvest logistics approach:<\/p>\n<div style=\"display: flex; flex-wrap: wrap; gap: 12px; margin: 20px 0;\">\n<div style=\"flex: 1 1 240px; background: #fafafa; border: 1px solid #e8e8e8; border-top: 4px solid #f07c00; padding: 18px 20px; border-radius: 0 0 6px 6px; box-sizing: border-box;\">\n<p style=\"font-weight: bold; color: #1a1a1a; margin: 0 0 8px 0; font-size: clamp(13px,1.4vw+8px,15px);\">Kit A \u2014 Side Windrow<\/p>\n<p style=\"margin: 0; color: #555; font-size: clamp(12px,1.3vw+8px,14px);\">Tubers are deposited in a side windrow alongside the harvested row. Manual picking from the windrow follows the digger pass. This is the lowest-cost output configuration \u2014 no additional collection equipment required \u2014 and is suited to small family operations where manual labour is available for the picking step. Not suited to operations above approximately 2\u20133 ha where manual windrow picking creates a labour bottleneck at the harvest timing peak.<\/p>\n<\/div>\n<div style=\"flex: 1 1 240px; background: #fafafa; border: 1px solid #e8e8e8; border-top: 4px solid #f07c00; padding: 18px 20px; border-radius: 0 0 6px 6px; box-sizing: border-box;\">\n<p style=\"font-weight: bold; color: #1a1a1a; margin: 0 0 8px 0; font-size: clamp(13px,1.4vw+8px,15px);\">Kit B \u2014 Rear Elevator to Cart<\/p>\n<p style=\"margin: 0; color: #555; font-size: clamp(12px,1.3vw+8px,14px);\">A rear elevator transfers clean tubers from the web separator discharge into a collection cart or bin trailer following directly behind the digger. The operator drives the tractor (with digger) forward; the cart follows automatically on its own wheels behind. When the cart is full, it is exchanged for an empty one \u2014 eliminating the windrow picking step entirely. This is the dominant configuration for Gangwon-do commercial potato operations in the 5\u201315 ha range where mechanical harvest without manual picking is the goal.<\/p>\n<\/div>\n<div style=\"flex: 1 1 240px; background: #fafafa; border: 1px solid #e8e8e8; border-top: 4px solid #f07c00; padding: 18px 20px; border-radius: 0 0 6px 6px; box-sizing: border-box;\">\n<p style=\"font-weight: bold; color: #1a1a1a; margin: 0 0 8px 0; font-size: clamp(13px,1.4vw+8px,15px);\">Kit C \u2014 Transfer Elevator to Trailer<\/p>\n<p style=\"margin: 0; color: #555; font-size: clamp(12px,1.3vw+8px,14px);\">A lateral transfer elevator moves tubers from the digger directly into a trailer running alongside (rather than behind) the digger. Suited to fields and tractors where a following-behind cart is not possible due to field width or headland constraints. Less common in Korean highland conditions than Kit B due to the requirement for a parallel-running trailer, but used on specific wide-terrace field geometries in North Gyeongsang and South Gyeonggi potato production zones.<\/p>\n<\/div>\n<\/div>\n<p><strong>Korean recommendation:<\/strong> For commercial operations above 5 ha targeting mechanical harvest with minimal manual labour, Kit B (rear elevator to cart) is the configuration that eliminates the manual windrow picking step while remaining compatible with Korean highland field geometries and tractor logistics. Kit A remains practical for operations below 2\u20133 ha where labour cost is managed through family farm structure rather than mechanization. Kit C is selected for specific field configurations where Kit B&#8217;s following-cart geometry is constrained.<\/p>\n<h3 style=\"font-size: clamp(16px,2vw+9px,22px); color: #1a1a1a; margin: 32px 0 14px 0;\">Why Row Spacing Matching Is Non-Negotiable<\/h3>\n<p>The EP-AWB-1600&#8217;s two lifting shares must travel beneath the tuber zone of two adjacent planted rows. The share spacing \u2014 the horizontal distance between the centrelines of the two lifting shares \u2014 must match the planted row spacing exactly. If the share centres and the planted row centres do not coincide, the shares travel partly beneath tubers rather than entirely below them: shares cut through the tuber zone, damaging tubers directly, increasing cull rates, and reducing revenue.<\/p>\n<p>The planted row spacing is set by the <a style=\"color: #f07c00; text-decoration: none; font-weight: bold;\" href=\"https:\/\/rock-crusher-tractor.com\/ko\/product\/psw-3200-rotavator-heavy-duty-tractor-mounted-rotary-tiller-with-3-0-3-6-m-working-width\/\">PSW-3200 \ub85c\ud130\ubca0\uc774\ud130<\/a> working width at tillage (Step 2 in the 7-step potato system), maintained through the furrower (Step 3), planter (Step 5), and cultivator (Step 6) \u2014 and must be confirmed before purchasing the digger. Confirm your planted row spacing measurement from the field before specifying the EP-AWB-1600 share spacing. A 5 cm mismatch between planned and actual planted spacing is common enough in Korean highland operations that field measurement is essential \u2014 do not order based on nominal system specifications alone.<\/p>\n<p><!-- SECTION 3: EP-AWB TRAILED AND EP-AWB-3200 --><\/p>\n<h2 style=\"font-size: clamp(20px,2.8vw+10px,30px); color: #1a1a1a; border-left: 5px solid #f07c00; padding-left: 16px; margin: 48px 0 20px 0; line-height: 1.3;\">EP-AWB Trailed Series and EP-AWB-3200 \u2014 For Larger Operations<\/h2>\n<p><img decoding=\"async\" style=\"width: 100%; height: auto; display: block; border-radius: 6px; margin: 20px 0 28px 0;\" title=\"EP-AWB Trailed \u2014 Higher Throughput Configuration\" src=\"https:\/\/rock-crusher-tractor.com\/wp-content\/uploads\/2026\/05\/Potato-Digger-Trailed-Overview.webp\" alt=\"EP-AWB trailed potato digger \u2014 4-row, higher throughput for Korean commercial potato operations above 15 ha\" \/><\/p>\n<p>The EP-AWB trailed digger series and the EP-AWB-3200 (4-row trailed) are suited to Korean potato operations above approximately 15 hectares annual harvest area, where the EP-AWB-1600&#8217;s 2-row throughput \u2014 typically 0.5\u20131.2 ha per hour depending on field length and logistics \u2014 creates a harvest timing constraint relative to the crop&#8217;s optimal harvest window.<\/p>\n<h3 style=\"font-size: clamp(16px,2vw+9px,22px); color: #1a1a1a; margin: 28px 0 14px 0;\">Why Throughput Matters in Korean Highland Conditions<\/h3>\n<p>Korean highland potato harvest timing is constrained by two overlapping factors: the crop&#8217;s physiological harvest maturity window (typically 80\u2013100 days after emergence, variety-dependent), and the weather window at harvest altitude. In Gangwon-do at 600\u2013800 m elevation, the period between optimal harvest maturity and the arrival of autumn rains that make field access difficult for heavy machines is often 3\u20134 weeks. For an operation with 25 hectares of potato, harvesting at 1.0 ha\/hour of productive digger time requires 25 hours of digger operation \u2014 achievable in 4\u20135 good-weather days with a 2-row mounted digger. If weather delays compress this window to 2\u20133 days, the 2-row digger cannot complete the harvest before deteriorating conditions close the field.<\/p>\n<p>The EP-AWB-3200 (4-row trailed) harvests at approximately double the row coverage rate of the EP-AWB-1600 in comparable conditions \u2014 1.0\u20132.0 ha per hour versus 0.5\u20131.2 ha per hour. For a 25-hectare operation, this doubles the harvest rate and halves the number of weather-window days required to complete the harvest. For operations above 20\u201325 hectares where weather-window risk is a meaningful production risk factor, the throughput advantage of the 4-row trailed configuration is a genuine risk management investment, not only a productivity improvement.<\/p>\n<h3 style=\"font-size: clamp(16px,2vw+9px,22px); color: #1a1a1a; margin: 32px 0 14px 0;\">Field and Terrain Requirements for Trailed Configurations<\/h3>\n<p><img decoding=\"async\" style=\"width: 100%; height: auto; display: block; border-radius: 6px; margin: 16px 0 24px 0;\" title=\"EP-AWB-3200 Trailed \u2014 4-Row Combined Operation\" src=\"https:\/\/rock-crusher-tractor.com\/wp-content\/uploads\/2026\/05\/Potato-Digger-Trailed-Combine.webp\" alt=\"EP-AWB-3200 trailed potato digger combined operation \u2014 4-row, suitable for large flat Korean potato farms in Pyeongchang-gun\" \/><\/p>\n<p>The trailed digger configurations have different field requirements from the mounted EP-AWB-1600 that are important to assess before selecting a trailed configuration for a Korean highland operation:<\/p>\n<p><strong>Row length:<\/strong> Trailed diggers require longer minimum row lengths than mounted diggers because the tractor-plus-trailer combination requires more headland space at row ends for turning. As a practical guideline, rows below approximately 80\u2013100 m length make the headland turning frequency of a trailed digger disproportionately high relative to productive harvest time \u2014 the tractor spends an excessive fraction of its operating time turning rather than harvesting. For field sections with short rows, the mounted EP-AWB-1600 is more efficient despite its lower theoretical throughput. Korean highland potato fields with their characteristic terraced geometry and irregular lengths often have sections where the mounted digger is more appropriate even on operations large enough to justify a trailed machine.<\/p>\n<p><strong>Field slope:<\/strong> Trailed configurations are more sensitive to cross-slope and down-slope gradients than mounted configurations. A mounted digger pivots on the tractor&#8217;s rear hitch and can follow contour variation more flexibly than a trailed implement on its own fixed wheels. For Korean highland fields with slopes above 15% \u2014 common in the terrace sections of Hoengseong-gun and Jeongseon-gun \u2014 the mounted EP-AWB-1600 tracks field contour more reliably than trailed configurations at equivalent slopes. Large Korean potato operations with mixed field geometry \u2014 some flat, some sloped \u2014 often operate both a 2-row mounted and a 4-row trailed digger, assigning each to the field sections it handles most efficiently.<\/p>\n<p><!-- SECTION 4: EP-CWB-2L BIG BAG HARVESTER --><\/p>\n<h2 style=\"font-size: clamp(20px,2.8vw+10px,30px); color: #1a1a1a; border-left: 5px solid #f07c00; padding-left: 16px; margin: 48px 0 20px 0; line-height: 1.3;\">EP-CWB-2L Big Bag Harvester \u2014 For Direct Processing Supply<\/h2>\n<p><img decoding=\"async\" style=\"width: 100%; height: auto; display: block; border-radius: 6px; margin: 20px 0 28px 0;\" title=\"EP-CWB-2L Big Bag Harvester \u2014 Processing Supply Chain\" src=\"https:\/\/rock-crusher-tractor.com\/wp-content\/uploads\/2026\/05\/Potato-Harvest-Application-1.webp\" alt=\"Watanabe EP-CWB-2L big bag potato harvester \u2014 in-field FIBC packing for Korean processing potato supply chain\" \/><\/p>\n<p>The <a style=\"color: #f07c00; text-decoration: none; font-weight: bold;\" href=\"https:\/\/rock-crusher-tractor.com\/ko\/product\/ep-cwb-2l-big-bag-potato-harvester\/\">EP-CWB-2L Big Bag Harvester<\/a> is a specialized configuration for Korean potato operations supplying directly to processing plants \u2014 chip manufacturers, starch processors, and industrial food companies that receive potatoes in 500 Kg FIBC (Flexible Intermediate Bulk Container) &#8220;big bags&#8221; rather than in bulk or smaller-unit packaging.<\/p>\n<p>The EP-CWB-2L harvests and grades the potato in-field \u2014 eliminating the packhouse intermediate step \u2014 and fills the product directly into big bags positioned on the machine.

Korean operators who invest in the complete Watanabe upstream system report consistently better harvest quality outcomes than operators who use the digger on fields prepared with incomplete or mismatched upstream equipment. The connections are direct:<\/p>\n<p><strong>Stone clearance (Steps 1\u20133) \u2192 Digger share and web longevity.<\/strong> Residual stones above 10\u201315 cm in the harvest zone contact the lifting shares directly, causing accelerated wear and in the worst case, sudden impact damage that stops the harvest operation. The complete stone clearance sequence \u2014 THOR crusher + CT-2100 picker \u2014 protects the digger by eliminating the stones that cause share damage. Operators who skip thorough stone clearance to save preparation costs frequently incur higher annual digger maintenance costs that exceed the preparation savings.<\/p>\n<p><strong>Rotavator quality (Step 2) \u2192 Soil separation efficiency.<\/strong> The vibrating web separator on the EP-AWB-1600 is most efficient when the harvested soil is loose, friable, and uniform in particle size. Coarse-tilled soil with large unbroken clods \u2014 typical of 540 RPM rotavator passes on wet soil \u2014 clogs the web and reduces throughput, requiring slower working speed and producing more soil in the harvested tuber stream. Fine-tilled 1000 RPM seedbeds produce the loose, friable soil structure that allows the web separator to work at maximum efficiency.<\/p>\n<p><strong>Row alignment (Steps 3\u20137 consistency) \u2192 Share depth accuracy.<\/strong> The EP-AWB-1600 lifting shares must travel at precisely consistent depth beneath the tuber zone throughout each harvested row. If the row geometry is inconsistent \u2014 ridges that vary in height, rows that deviate from the machine&#8217;s centreline \u2014 the shares must be set conservatively deep to ensure they pass beneath the deepest tubers in the row. This conservative setting produces a larger soil volume per row meter on the web conveyor, reducing separation efficiency and throughput. Consistent ridging (Step 3) and consistent planting depth (Step 5) \u2014 both dependent on the quality of Step 2 rotavator tillage \u2014 are the upstream prerequisites for optimum share depth setting and maximum digger throughput.<\/p>\n<p><!-- SECTION 6: PLANNING THE HARVEST SYSTEM --><\/p>\n<h2 style=\"font-size: clamp(20px,2.8vw+10px,30px); color: #1a1a1a; border-left: 5px solid #f07c00; padding-left: 16px; margin: 48px 0 20px 0; line-height: 1.3;\">Planning Your Potato Harvest System \u2014 Configuration by Farm Type<\/h2>\n<h3 style=\"font-size: clamp(16px,2vw+9px,22px); color: #1a1a1a; margin: 28px 0 12px 0;\">Small Highland Family Farm \u2014 Pyeongchang-gun, 2\u20135 ha<\/h3>\n<p><strong>Configuration: EP-AWB-1600 with Kit A or Kit B.<\/strong> At 2\u20135 ha annual harvest, the 2-row mounted digger completes the harvest comfortably within a 2\u20133 day weather window. Kit A (side windrow) for family operations with available manual picking labour; Kit B (rear elevator to cart) for operations transitioning away from manual picking. The 75 HP tractor that runs the furrower, planter, and cultivator is the same tractor for the digger \u2014 no additional tractor investment required.<\/p>\n<h3 style=\"font-size: clamp(16px,2vw+9px,22px); color: #1a1a1a; margin: 28px 0 12px 0;\">Medium Commercial Operation \u2014 Hoengseong-gun, 10\u201320 ha<\/h3>\n<p><strong>Configuration: EP-AWB-1600 Kit B as primary; consider EP-AWB Trailed for flat sections.<\/strong> At 10\u201320 ha, the weather-window risk begins to be relevant \u2014 harvest speed becomes an operational consideration alongside equipment cost. An EP-AWB-1600 Kit B (rear elevator to cart) combined with two collection carts allows continuous harvest operation without stops \u2014 one cart collects from the digger while the other is transported to the field headland for unloading. This dual-cart approach increases the effective harvest rate of the 2-row mounted digger to near its theoretical maximum. For flat field sections above 100 m row length, a trailed configuration might be considered as a second machine to further increase throughput on the easiest field sections.<\/p>\n<h3 style=\"font-size: clamp(16px,2vw+9px,22px); color: #1a1a1a; margin: 28px 0 12px 0;\">Large Commercial Operation with Processing Supply \u2014 25+ ha<\/h3>\n<p><strong>Configuration: EP-AWB-3200 (4-row trailed) for flat sections + EP-AWB-1600 for slope sections; EP-CWB-2L if processing-plant big-bag supply.<\/strong> At 25+ ha, throughput is the primary constraint. Operating both a 4-row trailed (for flat, long-row sections) and a 2-row mounted (for sloped and short-row sections) maximises daily harvested area across mixed field terrain. The EP-CWB-2L is selected instead of the trailed series when the operation has a contracted processing plant that receives and pays premium for big-bag direct-from-field delivery \u2014 the elimination of packhouse intermediate handling cost and the supply chain simplification justify the machine investment at this scale.<\/p>\n<p><!-- FAQ --><\/p>\n<h2 style=\"font-size: clamp(20px,2.8vw+10px,30px); color: #1a1a1a; border-left: 5px solid #f07c00; padding-left: 16px; margin: 48px 0 20px 0; line-height: 1.3;\">Frequently Asked Questions \u2014 Potato Digger Selection<\/h2>\n<div style=\"display: flex; flex-direction: column; gap: 0;\">\n<details style=\"border-bottom: 1px solid #e5e5e5; padding: 16px 0;\">\n<summary style=\"font-weight: bold; color: #1a1a1a; cursor: pointer; font-size: clamp(14px,1.6vw+8px,16px);\">How exactly do I measure my planted row spacing to confirm digger share compatibility?<\/summary>\n<p style=\"margin: 12px 0 0 0; color: #555;\">After planting, measure the centre-to-centre distance between two adjacent planted rows in multiple locations along the row length \u2014 not just at the row ends. Use a tape measure to the ridge centreline (the highest point of each ridge) rather than the ridge edge. Take five measurements at random positions along a 50-metre row length and average them. This average is the planted row spacing that the digger shares must match. Variations of more than 3\u20134 cm between measurement points indicate inconsistent furrowing or planting \u2014 which will produce share mismatch in some sections even if the average matches. Report both the average and the maximum variation to your Korea Watanabe contact when specifying the EP-AWB-1600 share spacing.<\/p>\n<\/details>\n<details style=\"border-bottom: 1px solid #e5e5e5; padding: 16px 0;\">\n<summary style=\"font-weight: bold; color: #1a1a1a; cursor: pointer; font-size: clamp(14px,1.6vw+8px,16px);\">What happens to harvested yield if the digger shares are set too deep?<\/summary>\n<p style=\"margin: 12px 0 0 0; color: #555;\">Setting shares too deep (below the tuber zone) moves more soil volume per row metre onto the web separator than the crop volume requires \u2014 reducing throughput efficiency and increasing machine wear without benefiting harvest completeness. It does not significantly affect tuber damage. Setting shares too shallow (above the deepest tubers) is the damaging error: shares cutting through the tuber zone bruise and cut tubers below the share tip, creating damage that may not be visible at harvest but accelerates rot in storage. Set shares to travel 3\u20135 cm below the deepest expected tuber position \u2014 this usually means approximately 20\u201322 cm below the ridge surface for varieties with 15\u201318 cm maximum tuber depth in Korean highland conditions.<\/p>\n<\/details>\n<details style=\"border-bottom: 1px solid #e5e5e5; padding: 16px 0;\">\n<summary style=\"font-weight: bold; color: #1a1a1a; cursor: pointer; font-size: clamp(14px,1.6vw+8px,16px);\">Can the EP-AWB-1600 kit configuration be changed after purchase?<\/summary>\n<p style=\"margin: 12px 0 0 0; color: #555;\">Yes \u2014 the Kit A, B, and C configurations are output attachment systems that connect to the same EP-AWB-1600 base machine.

Two diggers become a consideration when the harvested area exceeds approximately 25 ha, field conditions are particularly challenging (high stone content requiring slow working speed, steep terrain with frequent headland turns), or when the crop consists of multiple varieties with different maturity windows that must be harvested in strict sequence to maintain variety purity for market specification.
