I built an onboard hydraulic jack for my mower. I just push a button and the front end of the mower goes up in the air 35 inches. Enough to change blades and clean under the deck. Still have some refinements to make to the jack, but it works. Eleven yr. old walks in and I'm sitting there making my mower go up and down, with this strange look on my face. She made some comment about how I needed to get out more!!!!!!!
