Anyone maintaining a John Deere 7290R will find more than 100 parts for exactly that model here. Start with trailer couplings, lighting or electrics.
Two jobs meet on a 7290R. The engine has to run cool and clean, and at the back there are heavy trailers and implements that load the hitch every single day. This page lists more than 100 new replacement parts for the John Deere 7290R, from GRANIT, Scharmüller, ROCKINGER, Sauermann and Walterscheid among others.
For the cooling system there are radiator hoses, such as the bottom hose to the radiator, and thermostats. You will also find temperature sensors and NOx sensors for the exhaust aftertreatment. A failed NOx sensor usually throws a fault on the display and can make the engine management cut back power until the fault is cleared, so keeping a spare on the shelf makes sense if you cannot afford downtime in the season.
When you change a radiator hose, fit new hose clamps, clean the stubs properly and bleed the system after topping up. Run the engine up to temperature with the cab heater on full, then check the coolant level again once everything has cooled down. Trapped air is a familiar cause of a temperature gauge that keeps wandering. A new thermostat should always go in with a new seal.
For starting there is a gear reduction starter, along with sleeves that belong to this model.
For the rear of the 7290R there are forced steering parts for trailers with a steered axle, including inserts for the Pick-Up Hitch. There are also support plates for the ball hitch, drawbar frames, automatic drawbars and separate drawbar noses. Adapter plates set the hitch at the right height and connector heads link the air brakes to the trailer. For work after dark there are LED work lights as spotlights and in an oval version.
On an automatic drawbar that sees daily use, check the latch every week. Make sure the pin drops fully home and the safety indicator shows locked before you head out on the road.
Look at the data plate on your tractor and find the reference number on the old part. On hoses and sensors it is usually printed straight onto the part. Compare it with the details on the product before you place the order.
The 7290R is one of the John Deere 7R series. Every sibling in that range has a page of its own, with the parts chosen for that specific model:
