CWB-2L Potato Harvester

📦 Complete Harvest — Zero Manual Picking

The CWB-2L digs, separates, cleans, and loads potatoes in one continuous operation. Tubers go directly from the ground into the trailer — 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.

🗃 Multi-Stage Separation — Clean Output

The 8.8-meter body houses multiple sieve stages plus dedicated haulm removal — 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.

🚀 Direct Trailer Loading — 3.9 m Elevator

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.

⚡ Only 100 HP Required

Despite being a full-size 2-row elevator harvester, the CWB-2L requires only 100 hp — remarkably low for a machine of this capability. This puts professional, fully mechanized harvesting within reach of the mid-range tractor segment, without the 150–250 hp requirement of many competing harvesters.

💰 Eliminates Manual Labor Costs

Manual potato picking typically requires 15–30 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.

💪 Gentle Tuber Handling Throughout

Every stage of the CWB-2L is designed to handle tubers gently — 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.

🥔 Fully Mechanized Commercial Harvest

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 2–5 km/h. One tractor, one operator, zero picking crews — the most labor-efficient harvest method available.

🚚 Professional Contracting — Premium Service

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 — delivering clean potatoes directly into the client’s transport at the field edge. Higher service value, stronger client retention.

🌾 Seed Potato Production — Quality Handling

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 — maintaining seed-grade quality from field through to store.

🌎 Labor-Scarce Regions

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 — removing the dependency on seasonal labor availability and eliminating the risk of unharvested crop due to worker shortages.

📋 Direct Field-to-Store Logistics

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 — and every handling event that is eliminated reduces bruising and quality loss.

Q1: What is the difference between a potato digger and the CWB-2L harvester?

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

Q2: How many hectares per day can the CWB-2L harvest?

At 75 cm row spacing and 3–4 km/h average speed: approximately 0.5–0.6 hectares per hour, or 4–5 hectares per 8-hour day. Actual output depends on soil conditions, stone content, yield level, and trailer changeover time.

Q3: Can the CWB-2L really run on 100 hp?

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.

Q4: What trailer does it load into?

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.

Q5: Does the CWB-2L remove haulm automatically?

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 10–14 days before harvest is recommended to reduce green material volume.

Q6: Should the field be stone-free?

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

Q7: How does potato quality compare to hand picking?

The CWB-2L’s multi-stage gentle separation produces harvest quality comparable to careful hand picking — with the advantage of consistency. Every tuber passes through the same controlled separation process, delivering uniform output quality across the entire field.

Q8: Can the CWB-2L be road-transported?

Yes. The trailed chassis with own wheels allows road transport behind the tractor. Note the 3.2 m width and 3.9 m height — check local transport regulations for escort or lighting requirements. The elevator folds or lowers for transport position.

Q9: Do you ship the CWB-2L internationally?

Yes, we export worldwide. Production takes 15–25 days. Given the CWB-2L’s size (8.8 × 3.2 × 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 for a detailed quotation.

Q10: What maintenance does the CWB-2L require?

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.
