It takes a pretty big guy to lift the back end of an 1100 lb GT, with or without implements or ballast. The engine weighs only a bit more than the hydro and final drive and it's behind the front axle. The 80 lb of tires and rims are a bonus.GTs' are a different animal! My GT has down pressure on the rockshaft, with a little travel in the links that connect to the 3PH arms.
That said, I can easily lift the back of the GT with the arms. I have done it when I got hung in a ditch, mowing. I threw a rock under the arm, lifted the tractor, and got it out. PHEW!! It saved a walk to the shed for another tractor!!
Actually, a good sized guy can pick up the back of a GT, they are not that heavy.
Except for Gravely, the engine is in the front. :dunno:
