Manufacturer:
Likely Perkins or SDF Group engine, common in Landini tractors of this era.
Model Designation:
Specific engine model details would be found within the manual, but typically a 4-cylinder turbocharged diesel.
Horsepower:
Approximately 85-90 HP (Gross), with PTO horsepower slightly lower.
Torque:
Specific torque figures would be available in the manual, typically in the range of 300-350 Nm for this engine class.
Injection Type:
Commonly direct injection, likely with a Bosch or similar mechanical or electronic injection pump.
Standard:
Varies by market and production year; likely Tier 3 or equivalent for its era.
Type:
Typically a 12-speed or 16-speed manual transmission with synchronized gears, potentially with a Hi-Lo splitter (Powershuttle or Creep speed option).
Powershuttle:
Possible option for forward/reverse shuttle without clutch engagement.
Pto Speeds:
Standard PTO speeds (e.g., 540/1000 RPM) with engagement mechanism details.
Hydraulic Lift:
Mechanical or electronic draft control for 3-point hitch, with capacity specifications.
Wheelbase:
Estimated ~2300-2400 mm (standard for this class of tractor).
Overall Length:
Estimated ~4000-4500 mm.
Overall Width:
Estimated ~1800-2000 mm (depending on tire fitment).
Operating Weight:
Estimated ~3500-4000 kg (unballasted).
Max Allowable Weight:
Details would be in the manual, typically around 5000-6000 kg.
Features:
Basic instrumentation panel for engine status, speed, PTO RPM, fuel level, and warning lights. No advanced infotainment systems.
Features:
Mechanical controls for most functions. Potential for electronic draft control on the hydraulic lift, but not advanced driver assistance systems as found in modern vehicles.
Features:
No modern connectivity features.
Engine Oil Change:
Typically 250 or 500 operating hours, depending on oil type and operating conditions.
Hydraulic Fluid Change:
Typically 1000 operating hours or annually.
Air Filter Replacement:
Based on operating hours or when indicator shows restriction, often around 500 hours.
