When I changed my oil I talked to John Deere said to use 15-40 Mystick, well when I started to put the new oil in I took the cap off and I found this bunch of stuff like steel wool ,my guess it some kind of steel filter, I took that out and started to pour in the oil and it took about 10...
Really excited, drove it with temp outside at 8 degrees,little slow starting, glad I installed heater. Filled fuel up, is leaking out top were fuel gage goes in, so far only problem,changed oil and filter ,hope it warms up.
