The John Deere 6125J is a utility tractor produced between 2010 and 2020. Manufactured in Montenegro, Brazil, this model was designed to serve as a reliable workhorse for various agricultural applications, offering a balance of mechanical simplicity and operational performance.

Engine and Performance

The tractor is powered by a 6.8-liter, 6-cylinder liquid-cooled engine. It delivers 125 horsepower at a rated speed of 2300 RPM. The engine utilizes a rotary injection pump for fuel delivery and generates a maximum torque of 365.8 lb-ft at 1400 RPM, providing the necessary pulling power for field tasks.

Transmission and Drivetrain

The 6125J features a four-wheel drive system for improved traction. Operators have a choice between two transmission types: the John Deere SyncroPlus, which provides 12 forward and 4 reverse gears with full synchronization, or the John Deere PowrQuad, a partial power shift transmission offering 16 forward and 16 reverse gears. Both systems utilize an electro-hydraulic clutch and hydraulic wet disc brakes for reliable operation.

Hydraulics and Hitch

The hydraulic system is of a pressure-compensated type, with optional closed-center pressure-flow compensated (PFC) capabilities. The standard pump flow is 17.17 gpm (65.0 lpm), with optional configurations reaching up to 26.42 gpm (100.0 lpm). The rear hitch is a Category II type, featuring electronic lower link control and a maximum lift capacity of 8,378 lbs (3800 kg) at the ends.
