Displacement:
Approximately 3.8 Liters (3800 cc) (typical for V3800)
Horsepower Rated:
Approx. 105 HP (flywheel) (based on model number M105S)
Torque Peak:
Specific torque data would be in a service manual, but typically in the range of 300-350 lb-ft for this power class.
Injection System:
Direct Injection (likely Common Rail Diesel for this era)
Transmission Type:
Powershift or Hydrostatic Transmission (HST) are common in this series, specific to M105S variant.
Number Of Speeds:
Varies based on specific transmission option (e.g., 16F/16R Powershift, or infinite speeds for HST).

Typically every 500-1000 hours or annually.
Air Filter Replacement:
Regular inspection and replacement based on operating environment (e.g., dusty conditions).
Engine Oil Type:
Kubota UDT Fluid or API CJ-4/CK-4 SAE 15W-40 diesel engine oil (verify with service manual).
Hydraulic Fluid Type:
Kubota UDT (Universal Tractor Drive Train) fluid or equivalent ISO VG 46 hydraulic oil (verify with service manual).
Transmission Fluid Type:
Refer to transmission type; if powershift, may use specific transmission fluid; if HST, UDT is common. (verify with service manual).
Common Wear Items:
Clutch packs (if powershift), hydraulic pump wear, PTO clutch wear, seals, and filters are common wear items in tractors of this age and usage.
Electrical Connections:
Corrosion on electrical connectors can lead to intermittent issues, particularly in harsh environments.
Brand Origin:
Kubota Corporation, a Japanese company renowned for agricultural machinery, construction equipment, and engines since 1890.
