Overview

The Kubota M8-201 is a robust and versatile row-crop tractor designed for various agricultural tasks. It is powered by a Cummins B6.7 turbocharged diesel engine with a displacement of 408 cubic inches, a bore of 4.213 inches, and a stroke of 4.882 inches. The engine has a compression ratio of 17.3 to 1 and operates at a rated RPM of 2100, delivering a maximum power output of 179.86 horsepower. The tractor offers a choice between a six-speed power shift and a continuously-variable transmission, allowing for 30 forward speeds and 15 reverse speeds. The chassis is structured around a 4x4 MFWD 4WD configuration, ensuring optimal traction and stability across uneven terrain. Steering is facilitated through a power system, ensuring ease of maneuverability. The tractor stands at a commanding height of 128 inches and has an operating weight of 22090 lbs. It features a wheelbase of 114.0 inches and a drawbar height of 20.0 inches. The hydraulic system offers varying flow rates, with a maximum of 45.9 GPM at higher engine RPMs. Detailed performance data, including torque, drawbar pull, and fuel consumption rates under various conditions, are available from independent test results.
