Your John Deere 7250R from the 7R series has its own page here with more than 120 parts, including trailer couplings, lighting and electrics.
Hitches are only part of the story on the 7250R. Among the more than 120 parts that fit the John Deere 7250R you will also find components from deep inside the engine, such as injectors, sleeves, main bearings and thrust bearings. You will find parts made by GRANIT, Scharmüller, ROCKINGER, Sauermann and Walterscheid on this page.
When replacing an injector, always fit a new copper sealing washer and new O-rings, even if the old ones still look fine. Clean the injector seat in the cylinder head thoroughly before the new injector goes in, or compression will leak past it. Fuel system O-rings for the 7250R are available separately.
Main bearings and thrust bearings come into play during an overhaul. The thrust bearings set how far the crankshaft can move lengthways, so measure that end float before stripping the engine and again after assembly. Temperature sensors and radiator hoses, such as the top hose, complete the engine side. Replace the hose clamps at the same time, and only open the cooling system once the engine has cooled down.
LED work lights, including an oval floodlight, make night work far easier. Mount them on a rigid bracket, because a lamp that shakes with the cab ends up lighting the sky.
For the back of the tractor there are drawbar frames, support plates, drawbars, adapter plates and connector heads for the air brakes. Forced steering, for example an insert for the pick-up hitch, is what you need for trailers with steered axles. Check the support plate and the lock every time you change trailers.
A connector head that is stiff to turn or sticks when you uncouple is usually dirty or dry inside. Blow it out with compressed air, check the rubber seal and replace the head if the rubber has split. On the road, a leaking head only shows itself when the trailer starts braking poorly.
Read the type plate first so you know for sure it is a 7250R. Then look for the reference number on the old part. With injectors and bearings, that number is the only reliable way to pick the correct replacement.
The 7250R is part of the John Deere 7R series. The other models in that range each have their own page, handy for contractors running several 7R tractors:
The whole brand is under John Deere parts.
