It had a vg4d 4 cylinder 37hp wisconsin .plans are to re-power .but really with what i'm not sure .i have a vh4 thats smaller but it look as though its a small shaft size and bolt pattern different.if so i'm thinking if i have to go with an adapter of sort , a small three cylinder diesel might be better.maybe a kubota ,yanmar or perkins .i really don't know whats out there still kind of looking around.skid steer only had 482 hours on it and every thing is in good shape ,all pins and bushing are not wore out,the bucket in good shape and quick connect style.all the pumps worked well before the engine went pouf .
