3PX-2 Potato Cultivator

Core Technical Advantages

1. Active Rotary Blade System（24 Reinforced Blades）

The standout feature of the 3PX-2 is its 24 high-strength rotary blades. Operating at a standard PTO speed of 540 r/min, these blades aggressively break up soil clods and hardpans. This results in a fine, loose soil texture that promotes better root respiration and moisture infiltration compared to traditional tines.

2. High-Efficiency Double-Sided Hilling

Designed for double-sided soil displacement, the machine features a 200mm working width for its hilling components. It precision-moves soil from the furrows onto the ridges, building a tall, trapezoidal profile that suppresses late-season weeds and protects expanding tubers.

3. Robust Mounted Structure

With overall dimensions of 1420 x 1940 x 1300 mm, the 3PX-2 features a reinforced frame designed for stability. The standard 3-point hitch（Mounted type）

ensures easy maneuverability in tight headlands and high-speed transport between fields.

4. Optimized Power Transmission

The heavy-duty gearbox is engineered to handle the high torque required for active soil cultivation. It effectively distributes power to the rotary units, ensuring consistent performance even in heavy clay or stony soil conditions.

Why Invest in the 3PX-2?

• Enhanced Tuber Commercial Value: By providing superior ridge height and soil looseness, it prevents tuber exposure, reducing the rejection rate due to greening or mechanical bruising.

• Herbicide Reduction: The mechanical action of the rotary blades effectively uproots and mulches weeds, making it an ideal choice for Organic Potato Farming.

• Multi-Crop Capability: While optimized for potatoes, the 1.9m frame width and adjustable units make it highly effective for Ginger, Garlic, and Deep-Root Medicinal Herbs.

• Industrial Durability: Every component is built to Nine Harvest’s export-grade standards, ensuring long-term reliability in diverse global climates.

Frequently Asked Questions 

• Q: Can the hilling height be adjusted?

• A: Yes. The hilling depth and height can be precisely controlled via the tractor’s hydraulic lift and the machine’s own depth-adjustment wheels.

• Q: Are the rotary blades replaceable?

• A: Absolutely. The blades are made of heat-treated alloy steel for long life, but they are designed for easy individual replacement to minimize maintenance downtime.

• Q: Is this machine suitable for heavy clay soil?

• A: Yes. The active rotary system is much more effective in breaking down heavy clay than passive ridgers, creating a finer soil mulch for the crop.
