Liquid-cooled, with a radiator, thermostat, water pump, and fan. Specific coolant type and capacity will be detailed in the manual.

🔧 Transmission

Gearbox Type:

Synchronized constant-mesh manual transmission. Likely a range of speeds plus creeper gears on some models.

Transmission Features:

Some models may feature a two-speed PTO (540/1000 RPM) and a mechanical or hydraulic synchronizer for easier gear changes. All-wheel drive (4WD) is indicated by the '40' in model numbers (e.g., 3340, 4340).

Clutch Type:

Dry, single-plate or dual-plate clutch, operated mechanically.
