AWB Series Potato Digger 2-Row

📋 Four Models — Clear Upgrade Path

From the 800 kg, 75 hp entry-level AWB-1600 to the 1,350 kg, 95 hp full-featured AWB-1600 C — each step up adds build robustness, sieving capacity, and operator features. Start where your budget allows and upgrade later, or invest in the C model for maximum performance and longevity from day one.

🔄 2-Row Digging at 3–5 km/h

All models dig and separate two potato rows simultaneously at 3–5 km/h — covering approximately 0.5–0.8 hectares per hour at 75 cm row spacing. For small-to-medium potato farms and contractors, this is the most efficient and affordable way to mechanize the harvest.

⚡ Starting From Just 75 HP

The AWB-1600 runs on 75 hp — compatible with the compact tractors that dominate small farms worldwide. Even the top-tier AWB-1600 C requires only 95 hp. This means no tractor fleet upgrade is needed — plug into your existing equipment and start harvesting immediately.

🥔 Gentle Tuber Handling

The sieve web separates soil from tubers through controlled vibration — not aggressive impact. Potatoes ride across the web surface and are deposited gently onto the ground. This minimizes bruising, skin damage, and mechanical injury — critical for maintaining quality in both ware potato and seed potato markets.

🔧 Hydraulic Controls (B & C Models)

The AWB-1600 B and C add 2 double-acting hydraulic remotes for cab-controlled adjustments — depth setting, web speed, or implement position — without stopping or leaving the tractor. This improves precision, reduces operator fatigue, and allows real-time response to changing soil conditions across the field.

💰 Exceptional Value vs. Premium Brands

The AWB Series provides 2-row potato digging at a fraction of the cost of European brands. With four price points spanning entry-level to professional, there is an AWB model for every budget. Factory-direct pricing, fast delivery, and readily available replacement parts keep the total cost of ownership low.

🥔 Potato Harvesting — Dig & Windrow

The core application: dig two rows of potatoes, separate tubers from soil and debris, and deposit clean potatoes in a neat windrow for manual collection or mechanical pickup. This is the most common potato harvesting method worldwide for small-to-medium farms where full self-propelled harvesters are not economical.

🌾 Seed Potato Production — Gentle Handling

Seed potato producers need tubers lifted with minimal bruising and skin damage to maintain certification quality. The AWB’s vibrating sieve web provides gentle separation — avoiding the aggressive handling that causes internal bruising and reduces seed potato market value.

🍚 Root Vegetable Harvesting

Beyond potatoes, the AWB Series effectively digs and separates sweet potatoes, onions, garlic, carrots (with appropriate share adjustment), and other ridge-planted root vegetables. The adjustable digging depth and sieve aggressiveness accommodate different crop types and soil conditions.

🚚 Agricultural Contracting

Contract harvesters serving multiple small farms benefit from the AWB’s compact size, low power requirement, and easy transport between sites. The B and C models with hydraulic controls provide faster setup and more precise operation when moving between fields with different soil types and ridge configurations.

🌎 Smallholder & Development Projects

The AWB-1600 at 75 hp and 800 kg is purpose-built for the smallholder segment — the most affordable mechanized potato digger for farms transitioning from manual harvesting. It connects to standard compact tractors and immediately multiplies harvest productivity by 5–10× compared to hand digging.

Q1: What is the difference between the four AWB models?

All share the same 2-row, 540 RPM PTO platform. The differences: AWB-1600 is the lightest and most affordable (800 kg, 75 hp, no hydraulics). AWB-1600 A adds build robustness (1,000 kg, 85 hp). AWB-1600 B adds hydraulic cab controls (1,200 kg, 95 hp, 2 valves). AWB-1600 C is the heaviest and most durable (1,350 kg, 95 hp, 2 valves), with the longest sieve web for the cleanest separation.

Q2: How many hectares per day can the AWB dig?

At 75 cm row spacing and 3–5 km/h, all models cover approximately 0.5–0.8 hectares per hour. On an 8-hour day, that is 4–6 hectares of dug and separated potatoes — a dramatic improvement over manual harvesting.

Q3: Does the AWB collect potatoes into a bunker?

No. The AWB is a potato digger — it lifts, separates, and deposits tubers onto the soil surface in a windrow. It is not a self-loading harvester. Collection is done separately by hand or by a following pickup machine. This dig-and-windrow method is the most common and cost-effective harvesting approach for small-to-medium farms.

Q4: Can the AWB dig other root vegetables?

Yes. Sweet potatoes, onions, garlic, and other ridge-planted roots can be dug with the AWB by adjusting the share depth and sieve web aggressiveness. For carrots and parsnips, share geometry may need adaptation — contact us to discuss your crop.

Q5: Should the haulm be killed before digging?

For best results, yes. Removing or killing the potato haulm (tops) 10–14 days before harvest allows the tuber skins to set, reducing skin damage during digging. The AWB can dig without haulm destruction, but skin quality may be lower and green haulm can clog the sieve web in heavy-canopy conditions.

Q6: What is the advantage of hydraulic controls (B & C models)?

Hydraulic cab controls allow the operator to adjust digging depth, web speed, or implement position from the tractor seat without stopping. This is especially valuable when soil conditions change across the field — the operator can respond immediately, maintaining optimal dig quality and minimizing tuber damage.

Q7: Should the field be stone-free before digging?

Heavy stone content increases tuber damage and share wear during digging. We recommend managing stones before planting using a stone crusher, rock rake, or stone picker. Stone-free fields produce cleaner, higher-quality tubers with less mechanical damage at harvest.

Q8: What tractors are compatible?

AWB-1600: 75 hp+. AWB-1600 A: 85 hp+. AWB-1600 B & C: 95 hp+ with 2 double-acting remotes. All models use Cat 2 three-point hitch and 540 RPM PTO. Popular models include John Deere 5E/6M, New Holland T4/T5, Case IH Farmall, Kubota M6/M7, Massey Ferguson 4700/5700, Fendt 200/300 series.

Q9: Do you ship internationally?

Yes, we export all AWB models worldwide. Production takes 15–20 days. We handle all export documentation and offer CIF or FOB pricing. Please contact our team for a quotation.

Q10: What maintenance does the AWB require?

After each harvest season: inspect and replace worn digging shares; check sieve web rod/chain condition and tension; grease all bearings, pivot points, and PTO driveline; check slip clutch adjustment; inspect hydraulic hoses and connections (B & C models); tighten all bolts; and store under cover with protective grease on bare metal.
