Binding Type Binding Type: Digital Download (PDF) Paper Type Paper Type: N/A (Digital) ⚙️ Engine Specifications Primary Engine Engine Model Series: Onan (Specific model number not provided in product info, but likely a diesel or gasoline engine in the 2-4 cylinder range common for this tractor class). Performance Horsepower Range: Typically 15-30 HP, depending on specific Onan engine variant and tractor configuration. Torque Characteristics: Designed for strong low-end torque essential for pulling implements and maintaining power under load. Fuel System Fuel Type: Likely Diesel or Gasoline (depending on specific Onan engine option). Fuel Delivery: Typically indirect injection (diesel) or carburetor (gasoline). Cooling System Cooling Type: Liquid-cooled (common for Onan engines in this application). Lubrication System Oil Type: Refer to manual for specific Onan engine oil viscosity and API service classification (e.g., SAE 10W-30, API CI-4 for diesel). 🔧 Transmission Standard Transmission Type: Hydrostatic Transmission (HST) is highly probable for this model, offering variable speed control. Optional Optional Transmission: Less likely for this class, but manual might cover alternative gear-driven transmissions if offered. Features Pto Speeds: Standard PTO speeds (e.g., 540 RPM) and potentially mid-PTO configurations. Drive System: 2WD or 4WD (4WD typically optional). 📐 Dimensions Exterior Wheelbase: Variable, but compact tractors typically have wheelbases in the range of 60-75 inches. Overall Length: Approximate: 100-130 inches (without implements). Overall Width: Approximate: 45-60 inches. Weights Operating Weight: Approximate: 1500-2500 lbs (without implements). Lift Capacity: Refer to specific tractor model/configuration; typical at rear hitch points. 🛡️ Safety Features Ratings Safety Standards Compliance: Likely compliant with applicable ANSI/ASAE safety standards for agricultural tractors of its era. Active Features Operator Presence System: Likely equipped with an operator presence system that disengages PTO and/or transmission when the operator leaves the seat. Passive Features Rollover Protection: ROPS (Rollover Protective Structure) likely standard or optional, with associated seatbelt. 💡 Technology Features Infotainment Infotainment Features: N/A (Tractors of this era typically lack advanced infotainment systems; focus is on functional controls). Driver Assistance Driver Assistance Features: N/A (Basic tractor controls). Connectivity Connectivity Features: N/A 🔧 Maintenance Service Intervals Engine Oil Change: Refer to specific Onan engine manual or tractor service manual for recommended interval (e.g., every 50-100 operating hours). Air Filter Replacement: Based on operating conditions, typically checked at 50 hours and replaced as needed or annually. Hydraulic Fluid Change: Typically every 250-500 operating hours, or annually. Fluid Specifications Hydraulic Fluid Type: Tractor Hydraulic Fluid (THF) or equivalent, specified by CASE. Engine Coolant Type: Ethylene glycol-based antifreeze suitable for diesel or gasoline engines, typically 50/50 mix with distilled water. Transmission Fluid Type: Refer to manual; likely a specific hydrostatic transmission fluid or heavy-duty engine oil (e.g., 15W-40). Known Issues Common...
