Oil Capacity:
Refer to manual for specific capacity; typically around 5-6 liters.
Recommended Oil Grade:
Kubota UDT Fluid for transmission/hydraulics, API CG-4 or CH-4 rated diesel engine oil (e.g., 15W-40) for engine lubrication. Manual will provide exact specifications.
Transmission Type:
GST (Glide Shift Transmission) - Hydrostatic Transmission with clutch-assisted gear shifting capability.
Optional Transmission:
Likely manual transmission variants may exist (e.g., HST), but the manual explicitly states GST coverage.
Transmission Features:
Variable speed control, forward/reverse shuttle, hydrostatic drive, likely power shift capability within ranges.
Transmission Fluid Type:
Kubota UDT (Universal Draining & Transmission) Fluid is highly recommended. Manual will confirm exact specification and alternatives.
Transmission Fluid Capacity:
Refer to manual; typically around 20-30 liters.
Pto Speed:
Standard 540 RPM PTO. Manual may detail 540/1000 RPM configurations if applicable.
Overall Length:
Refer to manual for exact dimensions; typically around 3.3 meters.
Overall Width:
Refer to manual for exact dimensions; typically around 1.5 meters.
Wheelbase:
Refer to manual for exact dimensions; typically around 1.7 meters.
Operating Weight:
Approximately 1300-1500 kg (2866-3307 lbs), depending on configuration and options.
Rollover Protection:
ROPS (Roll Over Protective Structure) equipped as standard or optional; manual will detail installation and specifications.

Wet disc brakes, mechanical parking brake. Manual details adjustment and service.
Operator Presence:
Operator presence control system likely included for safety interlocks on PTO and transmission. Manual will detail operation.
Operator Interface:
Basic dashboard with essential gauges (tachometer, temperature, oil pressure, fuel level) and indicator lights. No modern infotainment system.
Cruise Control:
Not typically found on this class of tractor; manual will not cover.
Telematics:
No integrated telematics or connectivity features.
Engine Oil Change Interval:
Typically every 100-250 operating hours or annually, refer to manual for exact specification based on operating conditions.
Transmission Fluid Change Interval:
Typically every 500-1000 operating hours or every 2-3 years for UDT fluid. Manual provides definitive schedule.
Fuel Filter Replacement:
As needed or every 250-500 hours, depending on fuel quality. Manual will detail procedure.
Air Filter Maintenance:
Inspection and cleaning at 50-100 hour intervals, replacement as needed. Manual will detail cleaning procedure.
Engine Oil Spec:
API CG-4/CH-4, SAE 15W-40 (or consult manual for climate-specific viscosity).
Hydraulic Fluid Spec:
Kubota UDT Fluid is the primary recommendation. Manual will specify alternatives and viscosity grades.
Coolant Spec:
Ethylene glycol-based antifreeze with corrosion inhibitors, mixed 50/50 with distilled water. Manual will provide Kubota-specific recommendations.
Common Wear Items:
Hydraulic filters, engine air filters, fuel filters, and potential wear on PTO clutch components.
Gst Transmission Care:
Regular fluid and filter changes are critical for longevity of the GST transmission. Overheating can accelerate wear. Manual provides specific maintenance details.
