Overview

The Kubota M6-111 is a versatile and robust 4WD utility tractor, featuring a powerful four-cylinder Kubota V3800-TI-CRS turbocharged intercooled diesel engine with a displacement of 230 cubic inches. Based on independent test results, the engine delivers a maximum power output of 96.48 horsepower at 2500 rpm, with a rated power of 93.50 horsepower at 2602 rpm and the standard PTO speed of 540 rpm. The advanced selective gear fixed ratio transmission with partial (8) range operator-controlled power shift provides 24 forward and reverse gears. The tractor has a hydrostatic steering system and an operating weight of 10,005 pounds. Additional notable specifications include a maximum torque of 249 lb-ft at 1501 rpm with a 32.0% torque rise, fuel consumption of 6.09 gallons per hour at rated engine speed, and DEF consumption of 0.11 gallons per hour at rated power. The hydraulic system delivers a maximum power of 22.9 horsepower at 2433 psi, with a pump delivery rate of 16.1 GPM at maximum hydraulic power and 18.9 GPM at minimum pressure and rated engine speed. The tractor is equipped with 18.4R34 rear tires and 13.6R24 front tires, both at 12 psi pressure.
