Coolant Type:
Ethylene Glycol based antifreeze (50/50 mix with water)
Engine Oil Change:
Every 100 hours or annually, whichever comes first.
Transmission Hydraulic Fluid Change:
Every 500 hours or annually (Super UDT fluid). More frequent changes may be recommended under severe service conditions.
Air Filter Inspection:
Check daily or every 50 hours. Clean or replace as needed.
Fuel Filter Replacement:
Every 250 hours or annually. Bleed system after replacement.
Engine Oil Specification:
Kubota's recommended API CK-4 or CJ-4 diesel engine oil, viscosity SAE 10W-30 or 15W-40. Refer to the manual for exact part numbers and viscosity recommendations based on ambient temperature.
Transmission Hydraulic Fluid Specification:
Kubota Super UDT Fluid (Universal Transmission Drive Fluid). Crucial for HST performance. Use of incorrect fluid can cause severe damage.
