It covers removing the side panel to access the fill, draining and warming the oil, filter swap with part numbers (M806419, TY26674/TY26673), 15W40 oil, the 4.2-quart crankcase capacity, and checking for leaks afterward. Useful for owners planning their own DIY service and wanting real numbers rather than a general overview.
Posted by CREEKVIEW ACRES, an owner sharing hands-on maintenance from their own tractor rather than a dealership or professional shop.
You must remove the side panel by taking off a bolt and nut, releasing a turn lock tab, and removing another bolt and nut to pull the panel off.
According to the owner's manual, the crankcase with filter holds 4.2 quarts.
The filter part number is M806419, and the oil is John Deere 15W40 with part numbers TY26674 for the quart and TY26673 for the gallon.
The owner's manual says every 200 hours or annually, whichever comes first.
