How to Adjust the Wheel Height on a Lawnmower to Cut Tall Grass

Virtually all powered mowers and some old-fashioned mechanical mowers have a deck adjustment to raise the wheels for cutting tall grass. If you've been away on vacation or just let the lawn chores slide an extra week, raising the wheels to clip higher grass helps the mower operate more efficiently, with less strain and reduced risk of cutting off from clogged grass clippings. Adjusting the wheels takes only a few minutes, and no tools are necessary.

Instructions

    • 1

      Shut off the lawnmower.

    • 2

      Grab the handle that extends upward from the mower deck next to any wheel. Pull inward slightly to flex the handle away from the wheel.

    • 3

      Pull the handle toward the rear of the mower to raise the wheel to the desired height then release it so that the square cutout in the side of the handle locks onto one of the serrated prongs on the steel plate next to the wheel.

    • 4

      Repeat the adjustment with the remaining three wheels. Set each handle at the same height for level mowing.

    • 5

      Pull the handle inward then forward to lower the wheel height.
