The John Deere 6195M belongs to the 6M series, and this page lists more than 200 parts for it, including trailer couplings, electrics and lighting.
On the John Deere 6195M, plenty of breakdowns trace back to the wiring rather than the mechanics. That is why this page of more than 200 parts for the 6195M includes a good share of relays and sensors next to the drawbars and couplings. Brands include GRANIT, Sauermann, Scharmüller, Walterscheid and ROCKINGER.
Tip: when a light or function cuts out, swap the suspect relay with an identical one from a circuit that works. If the fault moves, the relay is to blame. If it stays, look at the fuse and the contacts in the relay holder, since corrosion there gives exactly the same symptoms. When buying a new relay, compare the pin layout and the diagram printed on the case, because some micro relays have a parallel resistor inside and others do not. Fitting the wrong one can upset the electronics on that circuit.
For the back of the tractor there are automatic drawbars, drawbar frames, flange hitches and trailer couplings. Trailer work is covered by forced steering units and air brake connector heads. Add O-rings for the fuel line, lockable fuel caps and handles for the cab, and most routine jobs on the 6195M are within reach. Replace a fuel line O-ring every time the line has been undone, even if the old one still looks fine.
Check the identification plate for the exact type. With relays and sensors, the reference number is printed on the housing in nearly every case, so you can match it with the items on this page. For a trailer coupling or flange hitch, the rail width and hole pattern on the tractor decide what fits.
The coolant temperature sensor is best changed with the engine cold. Have a drip tray ready, keep the new sensor within reach so the hole is open only briefly, and fit it with a new sealing ring. Do not overtighten it, as the thread in the housing is easily damaged. Top up the coolant afterwards and check that the gauge reads normally again.
Each other model in the 6M series has a page of its own: John Deere 6100M, John Deere 6110M, John Deere 6120M, John Deere 6130M, John Deere 6140M and John Deere 6155M. The 6175M and 6115M are part of the same series. The full line-up of the brand is on John Deere parts.
