Horsepower Bd2G:
Approximately 15-25 HP (exact figures vary by sub-model and year).
Horsepower Bs3G:
Approximately 25-35 HP (exact figures vary by sub-model and year).
Injection System:
Direct injection or indirect injection (specifics in manual).
Cooling Method:
Liquid-cooled
Oil Type Recommendation:
API CE or CF classification diesel engine oil, SAE 10W-30 or 10W-40 (refer to manual for exact specifications and viscosity grades based on temperature).
Transmission Type:
Manual transmission with multiple forward and reverse gears, often with a range selector (Hi/Lo).
Optional Features:
Some models may have offered partial powershift or shuttle shift functionalities (verify with manual).
Power Take Off Pto:
Rear PTO, typically 540 RPM, and potentially a mid-PTO for the loader/shovels.
Transmission Oil Type:
API GL-4 or GL-5 gear oil, SAE 80W-90 or 85W-140 (verify specific type and capacity in manual).
Wheelbase:
Varies by specific model configuration, typically 1500-1800 mm.
Overall Length:
Varies by specific model configuration, often 2800-3500 mm (excluding loader attachments).
Overall Width:
Varies by specific model configuration, typically 1300-1600 mm.
Operating Weight Bd2G:
Approximately 800-1200 kg.
Operating Weight Bs3G:
Approximately 1200-1700 kg (with loader).
Infotainment System:
Basic analog gauges for engine temperature, oil pressure, fuel level, and hour meter. No complex infotainment systems.
Driver Assistance Features:
No electronic driver assistance features; operation relies on operator skill and mechanical controls.
Connectivity Options:
None. Mechanical linkages and PTO for implement attachment.
Engine Oil Change:
Typically every 100-250 operating hours or annually, whichever comes first (refer to manual for exact interval and oil filter part numbers).
Air Filter Service:
Check daily, clean or replace as needed based on operating conditions; typical replacement interval 500 hours or annually.
Fuel Filter Replacement:
Typically every 500-1000 operating hours or annually.
Coolant Type:
Ethylene glycol-based antifreeze/coolant, typically a 50/50 mix with distilled water. Consult manual for specific type and capacity.
Hydraulic Fluid Type:
Tractor Hydraulic Fluid (THF) or universal tractor transmission oil (UTTO) meeting specific specifications (e.g., ISO VG 32/46 or UTTO 80W). Consult manual for precise fluid type, viscosity, and capacity.
Common Wear Items:
Clutch wear, hydraulic seal leaks, starter motor reliability, PTO engagement issues, and common diesel engine maintenance needs ( injectors, glow plugs).
Electrical Connections:
Corrosion in electrical connectors due to age and environmental exposure can cause intermittent faults.
Loader Cylinder Seals:
For the BS3G, loader hydraulic cylinder seals are a common wear item that may require periodic replacement.
Mitsubishi Heavy Industries Agriculture:
