Specific variant not listed, but this is a strong probability. Performance Horsepower Range: Approximately 60-70 PTO horsepower, depending on specific engine tune and configuration. Torque Characteristics: Designed for strong low-end torque crucial for pulling agricultural implements. Fuel System Fuel Type: Diesel Injection System: Likely Direct Injection with a Mechanical Fuel Injection Pump (e.g., CAV or Bosch) depending on the specific engine code. Maintenance Oil Capacity: Approximately 8-10 quarts (7.5-9.5 liters) with filter. Specific API rating for engine oil would be critical (e.g., API CE or CF). Coolant Capacity: Likely around 15-18 quarts (14-17 liters). Use of a 50/50 coolant/water mix is standard. 🔧 Transmission Standard Transmission Type: Likely a 8-speed (4 forward, 2 reverse with high/low range) or a 12-speed (Synchromesh with creeper gears) manual transmission. Optional Optional Transmission: Possible availability of a powershift or creeper gear option for specific applications. Features Power Take Off Pto: Standard 540 RPM PTO, with a potential option for a 1000 RPM PTO or a 2-speed PTO (540/1000). Maintenance Transmission Fluid Type: Typically a UTTO (Universal Tractor Transmission Oil) or similar hydraulic fluid. Referencing the manual for exact specification is crucial. 📐 Dimensions Exterior Wheelbase: Approximately 82-86 inches (208-218 cm). This can vary with 2WD/4WD configuration. Overall Length: Approximately 130-140 inches (330-355 cm), excluding implements. Overall Width: Typically around 70-80 inches (178-203 cm) at the rear axle, depending on tire size. Weights Operating Weight: Around 5,000-6,000 lbs (2268-2721 kg) for a 2WD configuration, without ballast. 🛡️ Safety Features Ratings Rollover Protection: ROPS (Roll Over Protective Structure) is a standard feature or a common aftermarket addition. The manual would detail its inspection and maintenance. Active Features Braking System: Hydraulically actuated, wet disc brakes are common for improved stopping power and durability. Passive Features Operator Station: Designed with operator safety in mind, including seating, controls placement, and accessibility. Manual covers safe operation procedures. 💡 Technology Features Infotainment Instrumentation: Basic analog gauges for engine temperature, oil pressure, fuel level, tachometer, and hour meter. Warning lights for critical systems. Driver Assistance Traction Control: Limited or no electronic driver assistance features. Traction primarily managed by operator input and appropriate tire selection/ballasting. Connectivity Connectivity Features: N/A (Basic agricultural machinery of its era) 🔧 Maintenance Service Intervals Engine Oil Change: Typically every 250 hours of operation or annually, whichever comes first. Refer to manual for precise interval. Air Filter Replacement: As needed, based on operating conditions and indicator, but typically checked at every oil change. Fuel Filter Replacement: Generally at 500-hour intervals or when issues arise with fuel delivery. Hydraulic Fluid Change: Typically every 1000-1200 hours, or annually, along with filter replacement.
