I purchased a used Craftsman model 917.273811 riding mower. I'm needing to replace the bolts that hold the little wheels on the deck but can't seem to find them. It doesn't help that I don't know the correct name for them let alone the part number. I'm just presuming that this model is close enough that the parts will be the same. So if you could send me the manual or the part number I would appreciate it very much.
