Specifically for the John Deere 6115M from the 6M series, with more than 300 parts including trailer couplings, electrics and lighting.
A 6115M rarely stays on one job for long. It swaps between trailers, a mixer wagon and a mower in a single day, and that shows in what is available for it. Of the more than 300 parts that fit this tractor, a large share are about hitching up, with plenty more for the electrical system and the engine bay. Suppliers include GRANIT, ROCKINGER, Scharmüller, Sauermann and Walterscheid.
At the rear of the 6115M you can fit drawbars with a ball or an automatic jaw, drawbar frames and flange hitches. If you pull a trailer with forced steering, there are forced steering parts too, such as the steering rod that connects to a ROCKINGER drawbar frame. Walterscheid supplies parts for the PTO and the linkage.
A practical point on drawbars: check the pin and the jaw for wear at every service. A pin that has worn oval creates play, and that play gets worse with every jolt when pulling away. Grease the guide in the frame so the height adjustment does not seize, and you can still move the drawbar with the lever in the middle of winter.
When an electrical function drops out, start with the relays. Swap the suspect relay with an identical one from a circuit that works. If the fault moves with it, you know the relay is to blame rather than the wiring loom.
The serial plate confirms you have a 6115M and not another model from the 6M series. For drawbars and frames, measure the rail width and pin diameter of what is fitted now. For electrical items, the number on the housing or label of the old part is the fastest clue. Check that number against the details listed with each part, so the replacement matches your 6115M.
