\u25c6 Product Overview<\/h3>\n

The CWB-2L Potato Harvester<\/strong> is a full-size, trailed 2-row elevator harvesting machine that digs, separates, elevates, and loads<\/strong> potatoes directly into a trailing truck or onboard bunker \u2014 delivering a completely mechanized harvest workflow with zero manual picking<\/strong>. Measuring 8,800 mm in length and weighing 4,500 kg, the CWB-2L is the most advanced and complete potato harvesting solution in the product lineup \u2014 a true one-pass harvester<\/strong> that replaces the dig-and-pick method entirely.<\/p>\n

Unlike potato diggers that deposit tubers on the ground for manual or secondary collection, the CWB-2L processes the entire harvest stream onboard: multi-stage sieve webs separate soil and debris, cleaning systems remove haulm and stones, and a high-reach elevator loads clean potatoes directly into a trailer running alongside \u2014 all at 2\u20135 km\/h with just 100 hp<\/strong> and 540 RPM PTO<\/strong>.<\/p>\n

Designed as a cost-effective alternative to premium European harvesters from brands such as Grimme, AVR, and Dewulf, the CWB-2L delivers professional harvest quality at a substantially lower investment \u2014 making fully mechanized potato harvesting accessible to a broader range of commercial growers and contractors.<\/p>\n

\u25c6 How the CWB-2L Potato Harvester Works<\/h3>\n

The CWB-2L executes the complete potato harvesting process within its 8.8-meter body \u2014 from underground ridge to clean potatoes loaded into a trailer:<\/p>\n

Stage 1 \u2014 Digging:<\/strong> Two heavy-duty digging shares penetrate beneath the potato ridges, lifting the entire soil-tuber-haulm mass onto the first intake web.<\/p>\n

Stage 2 \u2014 Primary Sieving:<\/strong> The first vibrating sieve web breaks up soil clods and allows fine soil to fall through back onto the field. The soil-removal process begins immediately, reducing the load carried forward through the machine.<\/p>\n

Stage 3 \u2014 Secondary Separation:<\/strong> A second (and potentially third) sieve stage further removes soil, small stones, and debris. The extended 8.8 m body provides enough room for multiple separation stages \u2014 each one progressively cleaning the tuber stream. Haulm rollers or separation fingers remove vine material and loose foliage.<\/p>\n

Stage 4 \u2014 Inspection & Cleaning:<\/strong> Clean tubers pass over a final inspection area where operators (when staffed) or mechanical deflectors can remove remaining clods, stones, or damaged tubers before the elevator stage.<\/p>\n

Stage 5 \u2014 Elevator Loading:<\/strong> A high-reach elevator (3.9 m height) lifts the cleaned potatoes and loads them directly into a trailer or truck running alongside the harvester. The elevator angle and position are hydraulically adjustable from the tractor cab via the 2 control valves, allowing precise filling of different trailer sizes and heights.<\/p>\n

Structural Composition:<\/strong><\/p>\n\n\n\n\n\n\n\n
\u25b6 Digging Shares<\/strong><\/td>\nTwo hardened steel shares with adjustable depth control. Designed to lift the full 2-row ridge width while minimizing tuber cutting and soil compaction beneath the harvested zone.<\/td>\n<\/tr>\n
\u25b6 Multi-Stage Sieve Webs<\/strong><\/td>\nMultiple PTO-driven vibrating conveyors in series progressively remove soil, stones, and debris. The extended 8.8 m body houses substantially more separation length than any potato digger, producing significantly cleaner output suitable for direct trailer loading without secondary grading.<\/td>\n<\/tr>\n
\u25b6 Haulm Separation<\/strong><\/td>\nDedicated haulm rollers or finger systems remove vine material, loose leaves, and stems from the tuber stream. This ensures only clean tubers reach the elevator, reducing post-harvest sorting labor.<\/td>\n<\/tr>\n
\u25b6 High-Reach Elevator<\/strong><\/td>\nA chain-and-web elevator extending to 3.9 m height lifts clean potatoes from the separation system and deposits them gently into a trailing truck, tipping trailer, or bulk container. Hydraulically adjustable position and angle ensure precise, damage-free filling.<\/td>\n<\/tr>\n
\u25b6 Trailed Chassis<\/strong><\/td>\nHeavy-duty self-supporting chassis with own axle and field-rated wheels. The 4,500 kg machine weight is carried on its own running gear \u2014 zero load on the tractor’s three-point hitch. Drawbar connection to the tractor provides towing force and PTO drive.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

\"CWB-2L<\/p>\n

<\/p>\n

\u25c6 Core Advantages of the CWB-2L Potato Harvester<\/h3>\n\n\n\n\n\n
\n

\ud83d\udce6 Complete Harvest \u2014 Zero Manual Picking<\/p>\n

The CWB-2L digs, separates, cleans, and loads potatoes in one continuous operation. Tubers go directly from the ground into the trailer \u2014 no windrows on the field, no hand-picking crews, no secondary collection pass. This eliminates the single largest labor cost in potato production and enables harvesting in regions where seasonal labor is scarce or expensive.<\/p>\n<\/td>\n

\n

\ud83d\uddc3 Multi-Stage Separation \u2014 Clean Output<\/p>\n

The 8.8-meter body houses multiple sieve stages plus dedicated haulm removal \u2014 far more separation capacity than any potato digger. Potatoes arriving at the elevator are substantially cleaner than digger output, reducing or eliminating the need for post-harvest grading and sorting. This means less labor at the storage facility and faster turnaround from field to store.<\/p>\n<\/td>\n<\/tr>\n

\n

\ud83d\ude80 Direct Trailer Loading \u2014 3.9 m Elevator<\/p>\n

The high-reach elevator loads clean potatoes directly into trailing trucks or tipping trailers at up to 3.9 m height. Hydraulically adjustable from the cab, the elevator fills different trailer sizes and heights precisely, with gentle deposition to minimize drop damage. No intermediate storage or handling between field and transport.<\/p>\n<\/td>\n

\n

\u26a1 Only 100 HP Required<\/p>\n

Despite being a full-size 2-row elevator harvester, the CWB-2L requires only 100 hp \u2014 remarkably low for a machine of this capability. This puts professional, fully mechanized harvesting within reach of the mid-range tractor segment, without the 150\u2013250 hp requirement of many competing harvesters.<\/p>\n<\/td>\n<\/tr>\n

\n

\ud83d\udcb0 Eliminates Manual Labor Costs<\/p>\n

Manual potato picking typically requires 15\u201330 workers per hectare harvested. The CWB-2L replaces this entire crew with one operator. On a 100-hectare farm, the labor savings in a single season can offset a significant portion of the machine’s purchase price. In regions with rising labor costs or seasonal worker shortages, the CWB-2L is an economic necessity.<\/p>\n<\/td>\n

\n

\ud83d\udcaa Gentle Tuber Handling Throughout<\/p>\n

Every stage of the CWB-2L is designed to handle tubers gently \u2014 from the sieve webs that vibrate rather than impact, to the elevator that deposits potatoes with controlled drop height. Minimizing bruising and skin damage is critical for both ware and seed potato markets, and the CWB-2L delivers harvest-quality output comparable to premium European machines.<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

<\/p>\n

\u25c6 Structure & Material Craftsmanship<\/h3>\n

Chassis:<\/strong> Heavy-duty welded steel trailed frame at 4,500 kg. The 8.8 m length accommodates the full multi-stage separation train and elevator within an integrated, rigid structure. Own axle with field-rated wheels and agricultural tyres. Drawbar hitch with PTO connection point.<\/p>\n

Digging Shares:<\/strong> Forged hardened steel with adjustable depth. Bolt-on replaceable. Designed to lift the full 2-row ridge width with minimum tuber damage.<\/p>\n

Sieve System:<\/strong> Multiple PTO-driven vibrating rod-link or chain conveyors in series. Each stage has optimized rod spacing and vibration characteristics for progressive soil removal. The total sieve path is substantially longer than any potato digger, providing superior separation quality.<\/p>\n

Haulm Removal:<\/strong> Dedicated roller or finger systems intercept vine material and foliage from the tuber stream, preventing green waste from entering the elevator and contaminating clean output.<\/p>\n

Elevator:<\/strong> Chain-driven web elevator with rubber-padded cups or flights for gentle tuber lifting. Maximum reach 3.9 m. Hydraulically controlled position and discharge angle via the 2 tractor control valves.<\/p>\n

PTO Driveline:<\/strong> 540 RPM cardan shaft with slip clutch drives all moving components \u2014 shares, sieve webs, haulm separation, and elevator \u2014 from a single PTO input.<\/p>\n

Surface Finish:<\/strong> All structural components shot-blasted and powder-coated for industrial-grade corrosion resistance.<\/p>\n

\u25c6 Application Scenarios \u2013 Where the CWB-2L Excels<\/h3>\n\n\n\n\n\n\n\n
\n

\ud83e\udd54 Fully Mechanized Commercial Harvest<\/p>\n

The primary application: harvest potatoes from field to trailer without human hands touching the crop. The CWB-2L digs 2 rows, separates soil and debris across multiple stages, removes haulm, and loads clean tubers into a trailing truck at 2\u20135 km\/h. One tractor, one operator, zero picking crews \u2014 the most labor-efficient harvest method available.<\/p>\n<\/td>\n<\/tr>\n

\n

\ud83d\ude9a Professional Contracting \u2014 Premium Service<\/p>\n

Contract harvesters offering full elevator-harvesting service command significantly higher per-hectare pricing than dig-and-windrow operators. The CWB-2L enables contractors to offer this premium, fully mechanized service \u2014 delivering clean potatoes directly into the client’s transport at the field edge. Higher service value, stronger client retention.<\/p>\n<\/td>\n<\/tr>\n

\n

\ud83c\udf3e Seed Potato Production \u2014 Quality Handling<\/p>\n

Seed potato producers need tubers harvested with minimal damage to maintain certification standards. The CWB-2L’s multi-stage gentle separation and controlled elevator deposition minimize bruising, skin scuffing, and mechanical injury \u2014 maintaining seed-grade quality from field through to store.<\/p>\n<\/td>\n<\/tr>\n

\n

\ud83c\udf0e Labor-Scarce Regions<\/p>\n

In regions where seasonal harvest labor is increasingly scarce, expensive, or unreliable, the CWB-2L provides a permanent solution. One machine and one operator replace an entire picking crew \u2014 removing the dependency on seasonal labor availability and eliminating the risk of unharvested crop due to worker shortages.<\/p>\n<\/td>\n<\/tr>\n

\n

\ud83d\udccb Direct Field-to-Store Logistics<\/p>\n

Because potatoes go directly from the ground into a road-going trailer, the field-to-store logistics chain is seamless. No intermediate piles, no re-handling, no secondary loading. The trailer drives straight from the field to the storage facility or packhouse. This reduces total handling events \u2014 and every handling event that is eliminated reduces bruising and quality loss.<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

\u25c6 Frequently Asked Questions \u2013 CWB-2L Potato Harvester<\/h3>\n\n\n\n\n\n\n\n\n\n\n\n\n
\n

Q1: What is the difference between a potato digger and the CWB-2L harvester?<\/p>\n

A digger lifts and separates potatoes, then deposits them on the ground for manual collection. The CWB-2L is a complete harvester \u2014 it digs, separates through multiple stages, removes haulm, and loads clean tubers directly into a trailer via an elevator. No manual picking is required.<\/p>\n<\/td>\n<\/tr>\n

\n

Q2: How many hectares per day can the CWB-2L harvest?<\/p>\n

At 75 cm row spacing and 3\u20134 km\/h average speed: approximately 0.5\u20130.6 hectares per hour, or 4\u20135 hectares per 8-hour day. Actual output depends on soil conditions, stone content, yield level, and trailer changeover time.<\/p>\n<\/td>\n<\/tr>\n

\n

Q3: Can the CWB-2L really run on 100 hp?<\/p>\n

Yes. The CWB-2L is designed to deliver full elevator-harvester capability at the lowest viable power level. In normal conditions, 100 hp provides sufficient PTO power for all functions. In very heavy clay or high-yield conditions, 120+ hp provides extra reserve. Compatible with John Deere 6M\/6R, New Holland T5\/T6, Case IH Maxxum, Kubota M7, Fendt 300\/500, Massey Ferguson 5700\/6700.<\/p>\n<\/td>\n<\/tr>\n

\n

Q4: What trailer does it load into?<\/p>\n

The 3.9 m elevator reach accommodates standard farm trailers, tipping trailers, and box-body trucks. Any trailer running alongside the harvester can receive the clean potato output. Elevator angle and position are hydraulically adjustable from the cab.<\/p>\n<\/td>\n<\/tr>\n

\n

Q5: Does the CWB-2L remove haulm automatically?<\/p>\n

Yes. Dedicated haulm rollers or finger separation systems intercept vine material and foliage, removing them from the tuber stream before the elevator stage. For best results, haulm destruction 10\u201314 days before harvest is recommended to reduce green material volume.<\/p>\n<\/td>\n<\/tr>\n

\n

Q6: Should the field be stone-free?<\/p>\n

Stone-free fields produce the best harvest quality. We strongly recommend managing stones before planting using a stone crusher, rock rake, or stone picker<\/a>. Stones damage tubers, accelerate wear on sieve webs and shares, and can jam separation systems.<\/p>\n<\/td>\n<\/tr>\n

\n

Q7: How does potato quality compare to hand picking?<\/p>\n

The CWB-2L’s multi-stage gentle separation produces harvest quality comparable to careful hand picking \u2014 with the advantage of consistency. Every tuber passes through the same controlled separation process, delivering uniform output quality across the entire field.<\/p>\n<\/td>\n<\/tr>\n

\n

Q8: Can the CWB-2L be road-transported?<\/p>\n

Yes. The trailed chassis with own wheels allows road transport behind the tractor. Note the 3.2 m width and 3.9 m height \u2014 check local transport regulations for escort or lighting requirements. The elevator folds or lowers for transport position.<\/p>\n<\/td>\n<\/tr>\n

\n

Q9: Do you ship the CWB-2L internationally?<\/p>\n

Yes, we export worldwide. Production takes 15\u201325 days. Given the CWB-2L’s size (8.8 \u00d7 3.2 \u00d7 3.9 m), shipping is typically via full container or flat-rack. We handle all export documentation and offer CIF or FOB pricing. Please contact our team<\/a> for a detailed quotation.<\/p>\n<\/td>\n<\/tr>\n

\n

Q10: What maintenance does the CWB-2L require?<\/p>\n

After each season: inspect and replace digging shares; check all sieve webs for worn rods or chain links; inspect haulm removal rollers\/fingers; check elevator chain, cups, and alignment; grease all bearings, pivot points, PTO driveline, and wheel hubs; inspect hydraulic hoses and cylinders; check tyre condition; tighten all bolts; and store under cover with protective grease on bare metal.<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
