I am changing the tires and rims on my L3010 and I don't have a jack appropriate to lift
rear to do that. What would it take to lift the rear to change tires?
buy a bottle jack
How Big? Its a Grand L 3010 with fluid in rear tires. I can lift the front wheels off with bucket and have done that before when I had a flat.
the whole tractor is about one and a half tons with FEL and loaded tires.
personally I would get a 5 or 10 ton jack (a lighter jack is harder to pump when they are near their rated load)
just make sure you lift on the correct part of the tractor or can damage the tractor. (I have seen those road side tire repair people bend axles on highway trucks ..more then once)
