Zirka IZ105 Motor Cultivator

Engine and Transmission Architecture

The core of the Zirka IZ105 is an air-cooled diesel engine, engineered for high torque at low RPMs. This is vital for heavy soil cultivation, as it allows the machine to maintain traction in virgin soil where gasoline-powered engines often lose power. The direct drive via a multi-plate oil-bath clutch minimizes energy loss and ensures smooth gear engagement, protecting the gearbox from impact stress.

Gearbox Construction

This model utilizes a heavy-duty gear drive system, eliminating the belt slippage issues common in entry-level machinery. The cast-iron gearbox housing serves a dual purpose: dampening engine vibration and providing the necessary weight to assist the tiller blades in soil penetration. The rear Power Take-Off (PTO) shaft allows the integration of active attachments, transforming the tiller into a versatile agricultural system.

Ergonomics and Durability

The steering column is adjustable in both height and horizontal angle. The ability to pivot the handles is essential for working alongside fences or in narrow rows, allowing the operator to walk beside the unit and avoid compacting the freshly tilled soil. The oil-bath air filtration system ensures the longevity of the piston group, even in the dusty conditions typical of intensive field operations.
