Engine Specifications Primary Engine Make: Kubota Model Family: V-series diesel engine (likely V2403 or similar variant) Displacement: Approximately 2.4 Liters (exact model specific, but typical for this class) Configuration: 4-cylinder, liquid-cooled, direct-injection diesel Performance Horsepower Rated: Around 36 PTO horsepower (Engine horsepower will be slightly higher, typically 40-42 HP). Exact rating is model-specific. Torque Peak: Specific torque figures not provided, but optimized for low-end grunt typical of Kubota diesels. Fuel System Injection Type: Direct Injection (DI) with high-pressure fuel pump. Fuel Type: Diesel Air Intake: Dry type air cleaner, often with a pre-filter. Maintenance Oil Type: Kubota UDT, Super UDT, or equivalent hydraulic/transmission fluid for hydrostatic models; engine oil grade specified in manual (e.g., SAE 10W-30 or 15W-40 depending on climate). Oil Capacity: Refer to manual for exact engine oil capacity (typically 6-8 quarts). Coolant Type: Ethylene glycol based antifreeze/coolant (typically 50/50 mix). Glow Plugs: Equipped with glow plugs for cold-weather starting. Transmission Standard Wet Variant: HST (Hydrostatic Transmission) with infinite speed control and pedal operation. Likely features a 3-range speed selection. Gst Variant: GST (Gear Shift Transmission) - likely a synchronized shuttle shift or powershift transmission with multiple forward and reverse gears. Optional Optional Transmissions: The manual covers both the WET and GST variants, implying these are the primary configurations offered. Features Clutch: Independent PTO clutch engagement, clutch pedal for mechanical transmission models. Pto: Rear PTO (540 RPM standard) and potentially a mid-PTO option. 4Wd: Four-wheel drive (4WD) capability, with engagement levers/switches. Maintenance Hydraulic Fluid Type: Kubota UDT (Universal Tractor Drive) fluid is typically recommended for hydrostatic transmissions and common hydraulic systems. Manual will specify exact Kubota part number. Hydraulic Fluid Capacity: Refer to manual for specific hydraulic fluid capacity (can be substantial, often 10+ gallons). Dimensions Exterior Length: Approx. 11-12 feet (3.3-3.7 meters) without attachments. Width: Approx. 5-6 feet (1.5-1.8 meters) without attachments. Height: Approx. 7-8 feet (2.1-2.4 meters) to the top of the ROPS (Rollover Protective Structure). Weights Operating Weight: Approx. 3000-3500 lbs (1360-1590 kg) without ballast or implements.
