Transmission Type Details
Gear Selection:
Mechanical gear levers for selecting transmission ranges and gears.
Overall Length:
Varies by model, typically around 3.8 - 4.2 meters.
Wheelbase:
Varies by model, approximately 2.1 - 2.3 meters.
Overall Width:
Varies by tire size and configuration, typically around 1.8 - 2.0 meters.
Ground Clearance:
Sufficient for agricultural operations, typically around 0.4 - 0.5 meters.
Unladen Weight:
Approximately 2,500 - 3,000 kg, depending on configuration.
Max Allowable Weight:
Significantly higher, supporting substantial implement loads and ballast.
Engine Oil Change:
Typically every 250-500 operating hours, or annually, whichever comes first (refer to manual for exact specification based on oil type).
Hydraulic Fluid Change:
Generally every 1000 operating hours or annually.
Engine Oil Type:
API CJ-4 or higher, SAE 15W-40 or 10W-30 depending on ambient temperature. Consult manual for precise OEM recommendations (e.g., CNH approval).
Hydraulic Fluid Type:
Tractor Hydraulic Fluid (THF) or UTF (Universal Tractor Transmission Oil) meeting CNH specifications, e.g., MAT 3525 or similar.
Coolant Type:
Ethylene glycol based antifreeze/coolant with corrosion inhibitors, typically a 50/50 mix with distilled water.
