vermeer sc252

*preface*. I know absolutely nothing about stump grinders but I do know this one needs a new engine. My daughter was gifted it and has used it for a year or so. It needs a new engine. She is wondering of the harbor freight 22hp predator would work with this stump grinder. It was suggested...

After pressure washing then blowing mostof the water off with an air blower, grinder won't turnover without the gas and hydraulic access lid fully in open position. Could anyone explain why this would happen or have ever had this happen to them?

I noticed that my sc252 driveshaft bearings that have three bolts holding them on the body that the main shaft that the tires and chain go on are completely shot. Anyone have the part numbers for these as I can't find them.
