Meets Tier 4A or Tier 4B emissions standards (depending on model year), potentially utilizing Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR) systems.
Type Standard:
Often equipped with a powershift (e.g., 24x24 or 16x16) or a synchronised shuttle transmission.
Type Optional:
Hydrostatic transmission (HST) may be an option on some configurations.
Features:
Power shuttle or electro-hydraulic reverser, multiple speed ranges, creeper gears may be available.
Fluid Type:
Case IH MS-135 hydraulic/transmission fluid or equivalent is commonly specified. Consult manual for exact specifications and interchangeability.
Length:
Approximately 4.3 - 4.6 meters (varies with configuration).
Width:
Approximately 2.0 - 2.4 meters (varies with tire size and configuration).
Height To Cab:
Approximately 2.6 - 2.8 meters (varies with tire size and cab height).
Operating Weight:
Typically in the range of 4,000 - 4,500 kg, depending on configuration and options.
Wheelbase:
Approximately 2.3 - 2.4 meters.
Rollover Protection:
ROPS (Roll-Over Protective Structure) is standard. Cab versions provide FOPS (Falling Object Protective Structure) and enhanced safety features.
Active Safety:
Dependable braking system, differential lock, power steering, operator visibility aids.
Passive Safety:
Seat belts, seat-mounted controls for ease of operation, cab safety glass.
Infotainment System:
Basic radio and audio systems are typical in the cab, with manual controls. Advanced infotainment is not a primary feature of this utility tractor class.
Driver Assistance:
Electronic draft control for hitch, PTO engagement controls, potentially cruise control or engine speed memory functions.
Connectivity Options:
Limited connectivity, typically focused on diagnostics via CAN bus for engine and transmission control modules.
Engine Oil Change:
Typically every 250-500 operating hours or annually, whichever comes first. Consult manual for specific interval.
Hydraulic Filter Change:
Recommended every 1000-1500 operating hours or as per manual recommendations.
Fuel Filter Replacement:
Recommended every 500-1000 operating hours, or when issues arise. Fuel water separator should be drained regularly.
Engine Oil Type:
API CJ-4 or API CK-4 rated diesel engine oil, typically SAE 15W-40. Check manual for specific viscosity and API classification.
Coolant Type:
Ethylene glycol based coolant with a 50/50 mix of antifreeze and distilled water. Fleetguard DCA or OAT coolant compatible with Case IH specifications.
