I would think a 20 hp engine will be lacking a bunch of HP to move a machine of this size, and lift abilities,
I would guess OEM, it was more like double the HP your engine now has
but I would think using what you got at least can confirm if things work, before buying something larger to drop in it!
you mentioned your electric motor and compared things to a golf cart
well a golf cart only weight a fraction as to what this skid steer does, so, thats a big difference on what it can move with gusto!, HAHA!
