Introduction

John Deere 6145J Utility Tractor

The John Deere 6145J is a utility tractor produced between 2010 and 2020 at the company's facility in Montenegro, Brazil. As part of the 6J series, this model is engineered to serve as a versatile solution for a wide range of agricultural operations requiring consistent power and mechanical reliability.

Engine and Performance

The tractor is powered by a 6-cylinder, liquid-cooled engine with a displacement of 6.8 liters (414.4 ci). It produces 145 hp (108.1 kW) at a rated speed of 2100 RPM. The fuel system utilizes a rotary injection pump, delivering a maximum torque of 448.4 lb-ft (608.0 Nm) at 1400 RPM, providing the necessary lugging capability for draft work.

Transmission and Drivetrain

The 6145J is equipped with the John Deere PowrQuad transmission, which features 16 forward and 16 reverse gears. This partial power shift system includes four power shift gears across four synchronized ranges, allowing for efficient speed adjustments under load. The drivetrain is supported by a four-wheel drive configuration, hydraulic wet disc brakes, and an electro-hydraulic differential lock to ensure traction in varied field conditions.

Hydraulics and Hitch

The hydraulic system is a closed-center, pressure-flow compensated (PFC) design. It delivers a pump flow of 26.42 gpm (100.0 lpm) at a pressure of 2900 psi (200.0 bar), with an SCV flow of 26.36 gpm (99.8 lpm). The rear hitch is a Category II type with electronic lower link control, providing a lift capacity of 10,160 lbs (4608 kg) at the ends, with optional higher capacities available for heavier implements.

PTO and Operator Environment

The independent rear Power Take-Off (PTO) is electro-hydraulically engaged and offers dual-speed capabilities of 540 and 1000 RPM. The tractor is configured with a four-post ROPS structure, with an enclosed cab available as an option to improve operator comfort during prolonged use.

Conclusion

The John Deere 6145J is a balanced utility tractor designed for farmers who require a combination of high torque, flexible gear selection, and robust hydraulic performance. Its mechanical configuration makes it well-suited for general field tasks, transport, and implement operation.
