Kubota M6-131

Last Updated: July 2024

Overview

The Kubota M6-131 is a durable and powerful agricultural tractor designed for a range of farming applications. It is powered by a Kubota V6108-TI-CRS (Serial No. 3FS0014) four-cylinder turbocharged and intercooled diesel engine with a displacement of 374 cubic inches, offering a rated power output of up to 113.31 horsepower at 2200 RPM. The engine features a bore of 4.646 inches and a stroke of 5.512 inches. Featuring a selective gear fixed ratio with partial (8) range operator controlled power shift transmission system with 24 forward and reverse gears, the tractor provides flexibility and efficiency in field operations. The M6-131 comes standard with a cab operator station, an electric starter system, and a Tier IV emissions standard compliance with Diesel Oxidation Catalyst (DOC), Selective Catalyst Reduction (SCR), and Diesel Particulate Filter (DPF). With dual dry element air cleaning and common rail direct injection fuel system, this model ensures optimal engine performance and longevity. The tractor boasts notable dimensions with a length of 171.7 inches, width of 85.8 inches, and a cab height of 113.2 inches, also having an unladen operational weight of 11300 lbs and a ballasted weight of 15635 lbs, which contributes to its stability and traction. Additional features include a maximum force exerted of 8613 lbs (38.3 kN) at hitch points, a pump delivery rate of 20.4 GPM (77.2 l/min) at minimum pressure and rated engine speed, a hydraulic power of 26.6 HP (19.9 kW) at delivery pressure of 2302 psi (159 bar), a maximum drawbar pull of 13467 lbs (59.90 kN) in 10th Gear (Ballasted), a maximum torque of 377 lb.-ft. (511 Nm) at 1252 rpm, and a torque rise of 39.5% with a power increase at 1850 rpm of 1.5%. Detailed fuel consumption rates and fuel efficiency metrics across various operational conditions are also provided.
