Typical Horsepower Range:
Approximately 40-100 PTO horsepower, varying significantly by specific model and engine configuration.
Fuel Type:
Diesel and Gasoline (depending on specific model variant)
Injection System Diesel:
Likely Bosch inline or rotary injection pumps, and distributor-type injection pumps.
Oil Type General:
API CD or CE rated diesel engine oil (e.g., SAE 15W-40 or 10W-30 depending on climate).
Transmission Type:
Various manual transmissions, including 8-speed, 16-speed (with/without creeper), and synchronized shift transmissions.
Transmission Options:
Power-assisted transmissions like Torque Amplifier (TA) or fully synchronized gearboxes on higher-end models.
Drive Options:
2WD (Rear Wheel Drive) is standard for most models in this range.
Transmission Fluid Type:
IH HyTran fluid or equivalent UTF (Universal Tractor Transmission Fluid) is commonly specified for hydraulics and transmissions.
General Size Range:
Compact to medium-duty utility tractors, with varying wheelbases and overall lengths.
Typical Operating Weight:
Range from approximately 3,500 lbs (1588 kg) for smaller models to over 7,000 lbs (3175 kg) for larger models.
Operator Station Safety:
Focus on operator safety features common for the era, such as operator presence controls, safety shielding for PTO and driveline components. ROPS (Roll Over Protective Structure) availability may vary by original configuration and year.

Typically mechanical drum brakes or hydraulic disc brakes on rear axle, with park brake mechanism.
Operator Station:
Open station design with operator seat, steering wheel, and controls. Some later models might have options for safety frames or cabs.
Operator Interface:
Basic analog gauges for oil pressure, water temperature, fuel level, and ammeter/voltmeter. Mechanical tachometer. No electronic infotainment systems.
Control Systems:
Mechanical linkages for throttle, clutch, gear selection, and power take-off (PTO) engagement. Hydraulic power steering on most models. 3-point hitch with draft and position control.
