Zirka GN151 Motor Cultivator

Heavy-duty performance for agricultural tasks

The Zirka GN151 is a classic heavy diesel walk-behind tractor equipped with a liquid cooling system, designed for cultivating plots up to 2–3 hectares. The machine is built on a robust frame architecture, which is essential for absorbing the peak loads experienced during virgin soil plowing or working with active rotary tillers.

Power unit and transmission

At the heart of the machine is a single-cylinder, four-stroke diesel engine with a rated output of 15 HP (R195 type). The liquid cooling system is a critical component for this class of machinery, preventing piston group overheating during prolonged operations in high ambient temperatures. The large radiator ensures stable thermal management during heavy-load cycles.

The transmission features a gear-driven gearbox with a multi-range setup: 6 forward and 2 reverse speeds. A key feature is the availability of high and low gear ranges, allowing for precise speed selection based on the specific implement used — from potato harvesters to rotary mowers. The differential lock significantly simplifies maneuvering such a massive machine, ensuring predictable handling even on soft or wet soil.

Chassis and ergonomics

• Drive System: Direct drive via a multi-disc clutch, which minimizes power losses compared to belt-driven alternatives.
• Power Take-Off (PTO): Allows the integration of active implements, transforming the walk-behind tractor into a fully functional multi-purpose agricultural vehicle.
• Weight: The mass of the unit provides the necessary traction for ground engagement without the need for additional weights, which is vital for plowing heavy loam or clay soils.

The handlebar assembly is adjustable for both height and steering angle, allowing the operator to customize the ergonomics to their stature, which reduces fatigue during long shifts. The Zirka GN151 is engineered for tasks where deep soil cultivation and heavy cargo hauling (up to 500–700 kg) are the primary requirements.
