John Deere 5420 Tractor Parts

5420 parts and accessories

The John Deere 5420 tractor, manufactured from 2003 to 2007, became a popular choice for farmers needing a versatile and reliable machine. Powered by a John Deere PowerTech 4.5L diesel engine producing approximately 74 horsepower, this tractor delivered ample power for a variety of tasks. Its independent 540 RPM PTO made it well-suited for operating implements like mowers, balers, and rotary cutters.

The John Deere 5420 was introduced in 2003 as part of the John Deere 5000 series, replacing earlier models and offering improvements in power, comfort, and features. Production continued until 2007. The 5420 is powered by a John Deere PowerTech 4045D 4.5L (276 ci) four-cylinder diesel engine, delivering approximately 74 engine horsepower and 63 PTO horsepower. Available transmission options included a SyncReverser transmission with 9 forward and 9 reverse gears or a PowrReverser transmission with 9 forward and 9 reverse gears offering clutchless shuttle shifting. The independent PTO provides 540 RPM speed. The hydraulic system has a capacity of around 15.9 GPM, powering two rear remotes. The three-point hitch is Category II, with a lift capacity of approximately 3,700 lbs. Common farming applications for the 5420 include hay production, livestock operations (feeding, manure handling), and light tillage. Compared to other models in the 5000 series, the 5420 offered a good balance of power and maneuverability for mid-sized farms, appealing to those needing more capability than smaller utility tractors but without the bulk of larger row crop tractors.
