Injection System:
Direct Injection, likely with Bosch or similar injection pump.
Cooling Type:
Likely Liquid-Cooled (radiator, fan, coolant).
Type:
Manual Synchromesh or Powershift transmission, often with a 16 or 24-speed gearbox. (Specific transmission type needs VIN verification).
Powershift Options:
Optional Powershift transmission may have been available for enhanced on-the-go shifting. (Confirmation needed).
Pto Speed:
Standard 540/1000 RPM PTO, with potential for ground speed PTO. (Check manual for specific PTO options).
Clutch Type:
Dual-stage dry clutch for PTO and transmission engagement.
Length:
Estimated 14-16 feet (4.2-4.8 meters) without implements. (Specific dimensions vary by configuration).
Width:
Estimated 6-7 feet (1.8-2.1 meters) at rear axle without duals. (Specific dimensions vary by configuration).
Height:
Estimated 8-9 feet (2.4-2.7 meters) to top of cab/exhaust. (Specific dimensions vary by configuration).
Operating Weight:
Estimated 7,000-9,000 lbs (3,175-4,082 kg) depending on configuration and ballast. (Manual will provide specific figures).
Wheelbase:
Estimated 85-95 inches (2.16-2.41 meters). (Specific wheelbase needs VIN verification).
Rollover Protection:
ROPS (Roll-Over Protective Structure) typically standard, with optional factory cabs offering enhanced protection. (Manual will confirm standards).
Braking System:
Hydraulically operated wet disc brakes. (Manual details maintenance and adjustment).
Lighting:
Standard headlights, taillights, and work lights. (Wiring diagrams in manual).
Engine Oil Change:
Typically every 250-500 operating hours. (Manual will specify exact interval and oil type).
Hydraulic Fluid Change:
Typically every 1000-2000 operating hours. (Manual will specify exact interval and fluid type).
Transmission Fluid Change:
