Zero Turn Mowers

Posted question earlier, no replies yet so I thought I would psot a few more. Actually got "into" the mower today. Cant find any fuel shut of per manual. Saw a yellow plastic plug clipped to side of engine, assume it is the oil drain even though the manual says there is a drain plug. Manual says there is a 20 amp fuse, nope. Tried adjusting deck wheels. sitting on mower, the left side of the deck, if you try to put wheel on middle hole, it hits the deck. Very happy with the cut and the mower. Any answers would be greatly appreciated.

Thanx Tom
