Looking for a place to introduce myself, and a PK question looks like a good one. I'm from west central Illinois in the Illinois River Valley. We live in a creek valley, and our property includes both bottoms and bluffs, almost entirely forested. We have three of the older metal-bodied Power King tractors that are used mostly for mowing and snow removal.
For the questioner, Larry Goss in Evansville, IN would be a good source of information for you. I don't know whether he's on this forum or not, but he's almost always available at the Power King Tractors Yahoo group. He is familiar with this model, and I believe he has one in Snapper colors. As to parts, Mission Mfg. of Princeton, IN has just about everything. Look at powerkingtractor.com for information, but you need to order by phone.
