A wide range of more than 500 parts fits the John Deere 6020. This page covers trailer couplings, electrics, and steering and front axle components.
Steering play on a John Deere 6020 is something you feel on every road trip, and it is often the first job that needs attention on a tractor of this type. This page carries more than 500 parts for the 6020, supplied by GRANIT, ROCKINGER, Sauermann, Scharmüller and HELLA.
Ball joints for the steering are available in several versions. When fitting one, make sure the taper and its seat in the steering knuckle are clean, dry and without grease, and secure the nut with a new split pin. For the ZF front axle there are external and internal plates, plus bushes, for example for the balancer shaft. Plates are always replaced as a full set and soaked in the correct oil before assembly. The ZF number is often stamped on the old plate itself.
Alternators, relays and micro relays with changeover contacts keep the electrical system running. Before you replace an alternator, measure the charging voltage with the engine running and check the belt and earth connection. A relay is easiest to test by swapping it with an identical one from another circuit. If the fault moves with it, you have found the culprit. If the alternator is not charging, look at the heavy charge cable to the battery as well. A corroded terminal produces the same symptoms as a failed regulator and is cured with a wire brush and a little terminal grease.
O-rings, gaskets and seals cover many positions, from the regulator housing gasket to the O-ring for the tank sender. Hoses are part of the range as well. In the cab there are tractor seats, including air suspended Maximo models. At the rear you will find drawbars, drawbar frames and forced steering units for trailers with a steered axle.
The type plate shows the model and serial number. The serial number matters because parts can change over the production run of a single model. The reference number on the old part is the final check, so compare it with the product description before ordering.
Other tractors in the same family each have their own page, so you only see what fits that particular type:
The 6520, the 6420S and every other John Deere model are reachable through the overview of John Deere parts.
