Displacement Approximate: Ranges from approximately 1.1 L to 1.5 L depending on specific STa model and engine. Horsepower Range Approximate: Typically between 28-35 gross horsepower, with PTO horsepower being lower. Performance Torque Characteristics: Designed for strong low-end torque suitable for heavy pulling and PTO-driven implements. Cooling System: Liquid-cooled (radiator, fan, thermostat, water pump). Fuel System Fuel Type: Diesel Injection System: Direct Injection (likely common rail or rotary injection pump depending on specific engine generation). Fuel Filter Type: Spin-on primary and secondary fuel filters. 🔧 Transmission Standard Type: Hydrostatic Transmission (HST) is a common standard for this series, offering infinite speed selection and forward/reverse pedal control. Optional Type: Some variants might have offered a gear-shift transmission (e.g., 8F/8R or similar synchromesh), though HST is more prevalent in this compact utility class. Features Cruise Control: Often equipped with HST cruise control for maintaining a set speed. Range Selection: Typically features at least two speed ranges (e.g., Low and High) for the HST. Fluid Specifications Fluid Type: Kubota UDT Fluid (Universal Tractor Drive Fluid) or equivalent universal tractor transmission oil (UTTO) meeting specific Kubota specifications. Fluid Capacity Capacity Approximate: Refer to manual for precise capacity, but typically around 4-5 liters (4-5.5 US quarts) for the HST transmission. 📐 Dimensions Exterior Overall Length Approximate: Varies by model, but generally around 3.0-3.5 meters (10-11.5 feet). Overall Width Approximate: Around 1.5-1.7 meters...
