Introduction
John Deere 4090: Row-Crop Tractor
The John Deere 4090 is a row-crop tractor produced between 1985 and 1986 by Chamberlain, a division of John Deere, in Welshpool, Australia. Designed for standard agricultural operations, this model was built with a focus on mechanical durability and field versatility.
Engine and Performance
The tractor is powered by a 6-cylinder, liquid-cooled John Deere diesel engine with a displacement of 359 cubic inches (5.9 liters). It delivers a net power output of 100.5 hp (74.9 kW) at a rated speed of 2200 RPM. The engine features a compression ratio of 16.8:1 and utilizes a dry air cleaner with a safety element, ensuring reliable performance in dusty field environments.
Transmission and Drivetrain
The drivetrain features a partial power shift transmission offering 12 forward and 4 reverse gears. It incorporates a hydraulic Hi-Lo power shift, allowing for on-the-fly gear adjustments within ranges. The system utilizes a 14-inch dry disc clutch. Gear shifting between the three main gears and the reverse requires the tractor to be at a complete stop, while range shifts are synchronized.
Hydraulics and PTO
The hydraulic system is of an open-center design, providing a total flow of 15.6 gpm (59.0 lpm) at a system pressure of 2500 psi (172.4 bar). It supports up to four valves for implement control. The rear independent PTO operates at 540 RPM as standard, with an optional 1000 RPM configuration available, engaged via a hydraulic disc clutch.
Hitch and Dimensions
Equipped with a Category II rear hitch, the tractor provides a lift capacity of 5,355 lbs (2,429 kg), with an optional upgrade available to 6,517 lbs (2,956 kg). The hitch utilizes top-link sensing for implement depth control. The base shipping weight is 11,671 lbs (5,293 kg) for the 2WD model, with MFWD 4WD versions weighing 12,302 lbs (5,580 kg).
Conclusion
The John Deere 4090 is a robust, mid-range row-crop tractor suited for traditional tillage and implement management. Its combination of a reliable 6-cylinder engine, partial power shift transmission, and standard air-conditioned cabin makes it a durable machine for operators requiring consistent performance in field applications.
