Need a trailer coupling, a lamp or a part from the electrics for the John Deere 8335R? This page groups more than 200 parts for the 8R/8RT series by model.
This page collects more than 200 replacement parts that fit the John Deere 8335R, made by GRANIT, Sauermann, HELLA, ROCKINGER, Scharmüller and others. A tractor of this size spends much of its life pulling heavy trailers and implements, so the hitch area is a good place to start.
For coupling up you will find drawbars with a ball, separate drawbar frames and adapter plates. Owners running a trailer with forced steering can replace the inner parts of that steering system, which takes the play out of the link between tractor and trailer. Connector heads for the supply and brake lines and trailer control valves complete the picture for air braked trailers.
A workshop tip on those connector heads: keep the dust caps closed whenever nothing is hooked up. Grit and water wear out the rubber seal quickly, and a leaking coupling usually shows itself as trailer brakes that respond late. If a head looks worn, replace it as a whole rather than just the seal.
With forced steering, check the ball mounting on the tractor before each season. If the ball moves in its holder, the trailer no longer tracks cleanly through bends and pushes its rear outward, which also scrubs the trailer tyres.
In the engine bay there are oil pressure sensors, temperature sensors for the inlet manifold, fuel line O-rings and a gear reduction starter. A faulty sensor can push the tractor into a limp mode even though the part itself is small and quick to change. An aircon compressor for the cab and seals for the door hinges and pull handles are here too.
When the evenings draw in, LED work lights, halogen work lamps and beacons keep the yard and the field lit.
Check the type plate first so you know for certain you are working on an 8335R. Once the old part is off, look for a stamped or printed reference number and compare it with the parts on this page. That small step avoids ordering a sensor with the wrong thread.
The 8335R belongs to the John Deere 8R/8RT series. Each of the other tractors in that series has its own page with the parts that fit it:
