John Deere 108 riding mower was built from 1979-1985. Has a Peerless 801 transaxle in it. Holds a bit over one quart of oil. I looked it up on line. Would need to remove breather cap and extract oil, or remove transaxle from mower, turn upside down, and then refill. This is the general procedure, not sure if it is exact for this specific Peerless.
