4U-90D Series: High-Performance Potato and Root Crop Harvester

Key Advantages for Potato Growers

1. "Anti-Bruise" Conveyor Technology

Potato quality is determined by the skin. The 4U-90D features a specialized conveyor chain with optimized spacing and protective coatings. This ensures that potatoes are gently tumbled to remove soil without the mechanical bruising that leads to rot during storage.

2. Superior Performance in Heavy Soil

Equipped with a Vibrating Flat Shovel, this harvester cuts through dense or "sticky" soil with ease. The vibration pre-loosens the soil bed, allowing the grid-sieve to separate mud and stones more effectively than static harvesters.

3. Precision Depth Management

Every centimeter counts in potato harvesting. Our integrated Depth-Limiting Wheels allow operators to maintain a precise digging level. This prevents the blade from cutting into the potatoes (too shallow) or dragging unnecessary soil (too deep), optimizing tractor efficiency.

4. Rugged Industrial Build

Designed for long harvest seasons, the 4U-90D is constructed from high-strength manganese steel. The reinforced frame and heavy-duty gearboxes ensure minimal downtime, even in stony or challenging terrains.

Applications & Versatility

While optimized for Potatoes, the 4U-90D's robust design also makes it suitable for:

• Sweet Potatoes

• Garlic & Onions
