Engine Type:
Diesel (assumed for this era of Kubota tractor)
Displacement:
Specific displacement not provided in product info, but typical for its class might range from 1.0L to 2.0L.
Horsepower:
Specific HP not provided, but likely in the 20-30 HP range based on model number convention and historical data for similar Kubota models.
Fuel Delivery:
Likely indirect injection, common for this era.
Cooling Method:
Liquid-cooled (standard for tractors of this size)
Oil Type Recommendation:
Refer to specific manual sections for Kubota UDT or similar fluids, but typically API CD or CE rated diesel engine oil (e.g., 15W-40).
Transmission Type:
Manual Gearbox with Main Speed Change
Transmission Options:
While not explicitly stated, some models of this era might have had slight variations or PTO options.
Gear Selection:
Likely multiple forward and reverse gears, managed by main speed change and range selection.
Fluid Type:
Kubota UDT (Universal Transmission Fluid) or equivalent for hydraulic/transmission fluid, and appropriate gear oil for the final drive.
Standard Safety Features:
Reflects original Japanese market configuration. North American models often required added safety features like PTO shields and seatbelts.
Braking System:
Mechanical brake system (likely drum brakes).
Operator Station:
Basic operator platform; potential for optional ROPS (Roll-Over Protective Structure) installation depending on original configuration.
Engine Oil Change:
Typically every 100-250 operating hours, or annually, depending on duty cycle. Refer to specific Kubota recommendations for diesel engines of this era.
Hydraulic Fluid Change:
Typically every 250-500 operating hours or annually. Crucial for transmission and hydraulic system health.
Engine Oil:
API CD or CE rated diesel engine oil, SAE 15W-40 is a common recommendation.
Hydraulic Transmission Fluid:
Kubota UDT (Universal Transmission Fluid) or equivalent.
Gear Oil:
EP (Extreme Pressure) gear oil, SAE 80W-90 for final drives and differentials if separate.
Coolant:
Ethylene glycol based antifreeze, typically a 50/50 mix with distilled water.
Wear And Tear:
Common issues with older tractors include hydraulic leaks, PTO spline wear, seal degradation, and potential issues with the clutch or transmission synchros if heavily used.
Electrical System:
Older wiring harnesses can degrade, leading to intermittent electrical issues. Battery terminal corrosion is also common.
Parts Sourcing:
This manual is critical for identifying correct replacement parts, as original part numbers are essential for sourcing.
