GASOLINE GARDEN TRACTOR | POWER TILLER | 196 CM3 (YT-85850)

The YATO YT-85850 walk-behind tractor is a single-axle basic power unit designed for mechanized tillage, area maintenance, and municipal works. The device's architecture is based on a direct power transmission mechanism and a wet clutch, ensuring efficient torque transfer without power loss from belt drives. The walk-behind tractor is adapted for aggregation with active and passive implements via a standardized power take-off (PTO) shaft.

Key Engineering and Design Parameters:

• Engine: Four-stroke, single-cylinder internal combustion engine LONCIN G200FD with air cooling.

• Displacement and Power: 196 cm³ displacement generates 4.1 kW (5.58 HP) of power at a maximum of 3600 rpm.

• Starting System: Duplicated starting system, integrating manual and electric starter (supplied with a 12 V, 6500 mAh lead-acid battery).

• Clutch and Lubrication System: Wet clutch and oil bath lubrication system ensure component cooling and protection against wear under heavy loads.

• Transmission: Mechanical gearbox with 3 forward gears and 3 reverse gears.

• Power Take-Off (PTO): Operating speed reaches 990 rpm when engine speed is 3600 rpm.

• Control Mechanism: The handlebar is adjustable on vertical and horizontal axes and has a 180-degree rotation function, allowing the walk-behind tractor to be adapted for working with front or rear-mounted equipment.

• Chassis: 500 mm diameter (5.0 x 10) pneumatic wheels, ensuring grip and off-road capability.

• Weight and Dimensions: Net weight of the device is 104 kg, dimensions – 104 x 61.5 x 77.5 cm.

Operational Data:

• Forward Gear Speeds: 1st gear – 1.30 km/h; 2nd gear – 3.00 km/h; 3rd gear – 4.40 km/h.

• Reverse Gear Speeds: 1st gear – 1.40 km/h; 2nd gear – 3.20 km/h; 3rd gear – 4.70 km/h.

• Operational Fluids: Unleaded gasoline E10 is used (fuel tank capacity 3.6 l). SAE 15W-40 oil for the engine (crankcase capacity 0.6 l), and GL-5 SAE 80W-90 standard oil for the transmission.

• Acoustic Parameters: Sound pressure level 82.5 dB(A).

Compatibility and Peripheral Equipment:

Due to the integrated PTO shaft, the walk-behind tractor functions as a universal platform. The system architecture supports connection to a wide range of YATO accessories (models from YT-85860 to YT-85881). Available working aggregates include plows, tillers, rotary and flail mowers, brushes, furrowers, cultivators, snow blowers, potato diggers, and snow blades. Additionally, metal wheels, PTO shaft extenders, axle wideners, wheel weights, and quick coupling sleeves can be integrated.
