My 88 316 refurb project is moving along, ive got the motor out and am sealing up some oil leaks on it, i replaced all the hydro hoses on the tractor, but am not quite ready to fill it up, bc i am replacing the h1 valve with a 317 h2 valve, and am waiting on some parts to come in to actually hook it up. My question is, am i safe to push the tractor in and out of the garage with the hydro drained? I would just use a jack or car wheel dollies, but i wanna get it out on the gravel drive to degrease/pressure wash before the motor goes back in.....
