Wheelbase:
Approximately 80-90 inches (203-229 cm).
Overall Length:
Approximately 130-150 inches (330-381 cm).
Operating Weight:
Around 5,000-7,000 lbs (2,268-3,175 kg), depending on configuration and ballast.
Tare Weight:
Approximately 4,500-6,000 lbs (2,041-2,722 kg).
Operator Safety Features:
Standard ROPS (Roll-Over Protective Structure) might have been an option or standard depending on the year and regulations. Seatbelts are likely present. Emphasis on safe operating practices detailed in the manual.
Braking System:
Mechanical drum or disc brakes, with parking brake functionality.
Engine Oil Change Interval:
Typically every 100-250 operating hours, or annually, depending on operating conditions. The manual will provide precise intervals and oil type.
Transmission Oil Change Interval:
As specified in the manual, often tied to major service intervals or specific operating hours.
Hydraulic Fluid Change Interval:
Typically every 500-1000 operating hours, or as needed, with specific filter change recommendations.
Engine Oil Type:
API CD or equivalent diesel engine oil, with specific viscosity grade (e.g., 15W-40 or 10W-30) as per manual. Capacities around 10-12 quarts.
Hydraulic Fluid Type:
Manufacturer-specified hydraulic fluid or universal tractor transmission fluid (UTTF), e.g., Allis-Chalmers Hy-Gard or equivalent. Capacity likely around 10-15 gallons.
Coolant Type:
Ethylene glycol-based coolant with corrosion inhibitors, typically a 50/50 mix with distilled water. Capacity around 20-25 quarts.
Common Wear Items:
Hydraulic pump wear, clutch wear, starter/alternator issues, injector pump calibration, and potential seal leaks are common on tractors of this age.
Troubleshooting Focus Areas:
