Zirka GN151E Motor Cultivator

Tractive Potential of the Diesel Layout

The core of the Zirka GN151E is the R195AN single-cylinder water-cooled diesel engine. Unlike low-power alternatives, this 15 HP motor generates significant torque at low RPMs. For the operator, this translates into zero overheating during hours of ploughing heavy clay soils and the capability to drive active attachments, from rotary tillers to mower decks, with constant performance.

Transmission: Durability through Gears

The design team opted for a heavy-duty gear-driven transmission rather than a belt drive. This configuration eliminates slippage under peak loads, which is essential for deep tillage. The gearbox offers 6 forward and 2 reverse speeds. The low-range gears are critical for ploughing, allowing the operator to maintain minimal travel speed without sacrificing the necessary traction force.

Chassis and Control Engineering

• Differential Lock: Independent wheel control allows for maneuvering this heavy machine (curb weight exceeds 290 kg) in tight spaces with ease.
• Track Adjustment: The adjustable track width allows the user to adapt the tiller to the row spacing of various crops, preventing root damage during cultivation.
• Electric Starter: Given the high compression ratio of the diesel engine, the electric start system significantly simplifies cold-weather operations.

This model is designed for intensive farm use. The heavy tiller configuration with a low center of gravity ensures predictable behavior on slopes, while the water cooling system maintains operational stability in intense heat, where air-cooled systems often fail due to thermal overload.
