Bush hogging last week, blew the head gasket on the 841. Replaced over the weekend back bush hogging this morning. Heavy weeds and briars along a fence row. Stopped to back into a corner not realizing that I had run over and laid down a tee post. When I backed up the tee post went through the oil pan, journal on the crankshaft caught it and busted a hole in the side of the block that you can stick your fist through. Will tear it down later in the week to check internal damage. Going to need another block at the very least. Anyone in the west TN area got one or even a rebuildible engine? Driving a reasonable distance to get one is not a problem. Email is open.
