Hydraulic Diagnostics:
Troubleshooting for low hydraulic pressure, slow operation, or leaks, including pump performance tests and valve spool checks.
Depth:
Comprehensive from basic maintenance to detailed engine, transmission, and hydraulic system rebuilds.
Transmission Type Standard:
Synchromesh Manual Transmission (likely with multiple speeds and range selection, e.g., 16 Forward / 16 Reverse or similar).
Transmission Type Optional:
Possible options could include a PowrReverser (clutchless forward/reverse shuttle) or a hydrostatic transmission (HST) in some configurations.
Pto Speed:
Standard PTO speeds (e.g., 540 RPM, 1000 RPM, or ground speed PTO) controlled by a separate lever or clutch.
Gear Selection:
Multiple gear ranges and speed selections for optimal power application and ground speed.
Engine Oil Change Interval:
Typically every 250 hours or annually, whichever comes first. Consult manual for exact interval.
Hydraulic Fluid Change Interval:
Typically every 500-1000 hours or annually. Consult manual for exact interval and fluid type.
Air Filter Service:
Inspect regularly, replace when dirty. Consult manual for specific interval or condition-based replacement.
Transmission Fluid Change Interval:
If a separate transmission fluid is used, interval will be specified. If integrated with hydraulic, follow hydraulic fluid intervals.
Engine Oil Grade:
Kubota recommends specific API CG-4 or higher diesel engine oils (e.g., 15W-40 or 10W-30 depending on climate). Consult manual for exact specification.
Hydraulic Fluid Type:
Kubota UDT (Universal Transmission Fluid) or equivalent for transmission, hydraulics, and PTO. Consult manual for precise specification.
Coolant Type:
Ethylene glycol-based antifreeze with corrosion inhibitors. Consult manual for specific type and mixture ratio.
Common Wear Items:
Clutch plates, brake pads, hydraulic seals, and certain pivot points are common wear items on tractors of this age and type.
Electrical Connection Corrosion:
Corrosion in electrical connectors can sometimes lead to intermittent issues, particularly in humid or exposed environments.
