Pro-Lift Lawn Mower Lift Hydraulic Jack 550 Lbs

What they don't tell you is the lift has to be all the up or the mower you're lifting will slide off the lift. Even though the lift has graduated stops for the safety arms, you can't use them as the lift will lean forward towards the mower, then kick out towards the operator dropping whatever you are lifting hard to the floor.Very unsafe. they don't advertise that the lift must be used all the way up and don't mention it in the instructions. I tried it with the brakes on in the mower and brakes off. The wheel cradles are not adjustable, therefore are always trying to let the mower slide off them. terrible product
