My hover mower doesn’t hover
This is a common complaint with people that are relatively new to hover mowers. 99% of the time you can sort this problem out by slightly tipping the lawnmower to one side (about an inch), so that air can get underneath it. Turn the lawnmower on and then gently tilt it back so that it is level again with the floor. Now air has been allowed to get underneath the lawnmower a cushion of air has formed, allowing the lawnmower to hover and glide across your grass.
