PK's were sold by couple other ventures near end. Yazoo Keyes had them awhile, never built any tho. Some outfit in Ill, don't know name, had them right after EP went under. Think most of these guys were selling older NOS tractors out of crates that were left over. I almost bought one like that. They were $7500 tractors around that time and you could get much more tractor in those days for same money. Plastics in big 16 and 24 models started in 85 with one piece hoods. Later (not sure when) they made three piece hoods and cleaned up the design alot. These were when the hydros were started. Early ones had controls in the right fender, and later at a foot pedal. This UT-620 was one of best made and had better attachments and quick-disconnect offered for front mounts. Some years they were made for Snapper, but didn't work out to long. Many Snapper dealers aren't even aware of the models that PK made for them. They don't acknowledge that time, yet I've seen the brochures and visited a dealer in IN that had those, seen them myself. This was about 94'. Sold for about $15,000 with loader and decks included. Could get a nice JD Utility for that money and be much better tractor.
