"Instead of struggling with improper jacks, or paying to have your lawn mower serviced, use the Guardian Hydraulic Lawn Mower Lift to safely elevate your lawn mower for easy access to the underbody. Manufactured with powder-coated steel, this lift can support up to 500 pounds of mower when one axle is lifted off the ground and the second axle stays on the ground. This lift has three locking height positions at 18.5"", 22.5"" and 26"", so that you can set it to the height best suited for your model and the type of maintenance work you want to perform. The open wheel tray fits wheels that are 18.75"", 23.75"" or 26.25"" wide."
