Type:
Direct Injection Diesel
Injection Pump:
Likely Bosch or similar reputable diesel injection system.
Type:
Pressurized, wet sump lubrication system.
Type:
Manual gearbox, likely with multiple forward and reverse gears. Common configurations include 8-speed or 12-speed options.
Powershift:
Possible, but less common for this series; manual will clarify.
Pto:
Standard rear PTO (Power Take-Off) with multiple speeds (e.g., 540/1000 RPM).
Differential Lock:
Likely features a rear differential lock for improved traction.
Clutch Type:
Dual-clutch (one for transmission, one for PTO) or single-plate dry clutch.
Length:
Specific dimensions not provided, but typical for a 55 HP tractor (approx. 3.5-4.0 meters).
Width:
Specific dimensions not provided, but typical for a 55 HP tractor (approx. 1.8-2.0 meters at rear axle).
Height:
Specific dimensions not provided, but typical for a 55 HP tractor (approx. 2.2-2.5 meters to top of ROPS/cab if fitted).
Operating Weight:
Estimated operating weight: 2000-2500 kg. Manual will provide exact figures.
Front Axle Weight:
DTF configuration implies significant front axle weight contribution.
Rear Axle Weight:
Designed to carry substantial load for traction and implement operation.
Rollover Protection:
Likely equipped with a Roll Over Protective Structure (ROPS) or a cab with ROPS protection, essential for operator safety.
Brakes:
Hydraulically actuated wet disc brakes (common on tractors of this era) for reliable stopping power.
Parking Brake:
Independent parking brake mechanism.
Seatbelt:
Operator seatbelt for ROPS-equipped machines.
Engine Oil Change:
Typically 250-500 hours, or annually, whichever comes first. Manual will provide exact interval and oil type.
Air Filter Service:
Check every 50-100 operating hours, replace as needed. Crucial for engine longevity.
Fuel Filter Replacement:
Recommended at 250-500 hour intervals, or when fuel system issues are suspected.
Engine Oil:
Refer to manual for specific API/ACEA ratings (e.g., SAE 15W-40, API CG-4 or similar).
Hydraulic Fluid:
Refer to manual for specific type (e.g., UTTO - Universal Tractor Transmission Oil) and viscosity grade.
Transmission Fluid:
Often shares hydraulic fluid, but manual will confirm. Check for specific gear oil grades for final drives if separate.
Coolant:
Ethylene glycol-based antifreeze mixture with appropriate corrosion inhibitors. Manual will specify ratio and type.
