2WD (Rear-wheel drive) is standard for this class of tractor.
Wheelbase:
Varies, but generally compact for maneuverability.
Tire Sizes:
Front and rear tire sizes would be specified, common for utility tractors of this era (e.g., 6.00-16 front, 12.4-28 rear).
Operating Weight:
Estimated 1500-2000 kg range, depending on configuration.
Front Axle Capacity:
Sufficient for engine and front linkage/loader if equipped.
Rear Axle Capacity:
Designed to handle engine power and implement loads.
Operator Safety:
Features would include roll protection (ROPS, potentially optional or field-fitted depending on era), seatbelt, and safety guards for PTO and other moving parts. Operator positioning and visibility are key design elements.
Braking System:
Mechanical or hydraulic drum brakes on the rear wheels, possibly a parking brake mechanism.
Engine Oil Change:
Typically every 100-250 operating hours, or annually. Manual will specify exact interval and oil type.
Fuel Filter Replacement:
Recommended at specified intervals, e.g., every 250-500 hours, or annually, and as needed if water is detected.
Air Filter Maintenance:
Check and clean daily or weekly depending on operating conditions; replace at specified intervals or when damaged.
Hydraulic Filter Replacement:
As per manufacturer's recommendation, likely tied to hours or annual service.
Engine Oil Specification:
Manual will specify viscosity grade (e.g., SAE 15W-30, 10W-30) and API service classification (e.g., CD or higher).
Coolant Specification:
Specify type of antifreeze (e.g., ethylene glycol based) and mixture ratio for protection against freezing and corrosion.
Hydraulic Fluid Type:
Manual will specify correct hydraulic fluid type, likely a tractor hydraulic fluid (THF) or equivalent, with correct viscosity.
Transmission Gear Oil:
Manual will specify appropriate gear oil viscosity and API service rating for the gearbox and differential.
