Refer to specific model variant in the manual, typically around 2.3 - 2.5 meters.
Rollover Protection:
ROPS (Roll Over Protective Structure) standard, often integrated into the cab frame.
Braking System:
Hydraulically actuated wet disc brakes in the rear axle housing. Parking brake integrated or separate.
Steering System:
Hydrostatic power steering for reduced steering effort.
Operator Station Design:
Designed with operator safety in mind, including safety glass, ergonomic controls placement, and operator presence controls.
Operator Interface:
Focuses on functional controls for tractor operation, rather than traditional automotive infotainment. Includes dashboard indicators, lever controls, and potentially digital displays for PTO speed or other functions.
Power Steering:
Standard hydrostatic power steering enhances ease of operation and maneuverability.
Transmission Control:
Electro-Command models feature electronic control for gear shifting and potentially powershift elements.
Implement Control:
Designed to interface with a wide range of tractor implements via the 3-point hitch, PTO, and hydraulic remotes.
Engine Oil Change:
Typically every 250 hours of operation or annually, whichever comes first.
Fuel Filter Replacement:
Recommended every 500 hours or annually, and more frequently if fuel quality is suspect.
Air Filter Service:
Inspect at daily checks, replace when indicated by service indicator or maximum dirt load. Engine air filter is critical for longevity.
