I had one of those a long time ago.
If they are the Promark models with the grinding wheels mounted on the rear be very careful using them. Promark had many lawsuits against them because of that design. The grinder would jump over the stump and go after the operators feet or the lower part of the leg.
I had a guy hurt with one of those machines. He didn't have the hand brake engaged and the grinder darn near took off his big toe and chewed his foot up pretty bad. He was accident prone as it was but it didn't matter. He was my employee. Cost my insurance company almost $10,000 in medical bills alone and this was well over twenty years ago. I don't know what he got for a settlement as it was a WC case.
I didn't know this when I bought mine but I sure found out about it later on.
I wouldn't put a hired man on one of those foot eaters. If you operate it by yourself that is your business. Yes, they are a workout for sure and throw chips everywhere.
I'd salvage the engines as they are worth more than what you paid for them, if they run good that is and get rid of the rest of the machine.

Good sound advice on who should run it and who shouldn't but I think somebody already mentioned what really needs to be done with that insane piece of scrap. I have never actually seen one of these only heard. Now I see What a stupid idea it is, Promark deserved the lawsuit.
I have used ( and was looking to buy) one of their models which didn't amputate your leg while you used it as it had the wheel in the front. These where decent if they where running well and sharp.
