Introduction
John Deere 4520 Compact Utility Tractor
The John Deere 4520 is a compact utility tractor produced between 2005 and 2014 at the company's manufacturing facility in Augusta, Georgia, USA. Designed for versatility in agricultural and property maintenance applications, this model belongs to a series that includes the 4320 and 4720.
Engine and Performance
The tractor is powered by a 2.4-liter, 4-cylinder liquid-cooled engine, generating 53 hp (39.6 kW) at a rated speed of 2400 RPM. It produces a maximum torque of 141 lb-ft (191.2 Nm) at 1440 RPM, providing consistent pulling power for various tasks. The engine utilizes paper and felt air filtration elements and maintains a compression ratio of 20.5:1.
Transmission and Drivetrain
Operators can choose between two transmission types: the PowrReverser or the eHydro. The PowrReverser transmission provides 12 forward and 12 reverse speeds across three ranges, allowing for directional changes without using the clutch. The eHydro transmission offers an infinite speed range across three operational modes using a two-pedal control system. Both versions are equipped with four-wheel drive and wet disc brakes for enhanced traction and safety.
Hydraulics and PTO
The hydraulic system features an open-center design with a total flow capacity of 17.1 gpm (64.7 lpm), with 12 gpm (45.4 lpm) dedicated to implement flow. It operates at a pressure of 2500 psi (172.4 bar) and can support up to five hydraulic valves. The rear power take-off (PTO) is independent, operating at 540 RPM, while an optional 2100 RPM mid-mount PTO is available for specialized implements.
Hitch and Dimensions
The tractor is equipped with a Category I rear three-point hitch, capable of lifting 3,130 lbs (1419 kg) at the link ends, or 2,500 lbs (1134 kg) at a distance of 24 inches behind the hitch point. The machine measures 128.2 inches in length with a wheelbase of 71.5 inches, offering a balance between stability and maneuverability in confined spaces.
Conclusion
The John Deere 4520 is a robust compact tractor suited for users requiring a balance of power and maneuverability. Its combination of multiple transmission choices, high hydraulic flow, and optional climate-controlled cab makes it a versatile machine for diverse utility and agricultural operations.
