The
Kubota M8200 is a 2WD or 4WD utility tractor from M-series. Thid model was
manufactured between 1997 and 2005. The Kubota M8200 tractor is powered by 202.1
cu.in (3.3L) Kubota V3300 4-stroke 4-cylinder direct Injection naturally
aspirated liquid-cooled disel engine with a rated power of 85.3 hp (63.6 kW).
The Kubota M8200 is fitted with two types of transmission. Type 1:
Synchronized shuttle transmission with 8 forward and 8 reverse gears.
Type 2: Power shuttle transmission with 8 forward and 8 reverse gears.
The maximum forward speed - 20.7 mph (33.3 km/h), maximum reverse speed
- 20.7 mph (33.3 km/h).
The open center hydraulic system used a gear pump with a flow rate of 17
gallons per minute (64.5 liters per minute). The main relief pressure is
195 bar (2825 psi). The M8200 is equipped with a hydrostatic power
steering, mechanical wet disc brakes, 7.50-18 (AG) or 9.5L-15 (Turf) 2WD
front tires, 12.4-24 (AG) or 27x8.50-15 (Industrial) 4WD front tires,
12.4-24 (AG) or 18.4-26 (Turf) 2WD rear tires, and 18.4-30 (AG) or
