Abstract
A single lever height adjustment mechanism for adjusting the height of an associated mower has an adjustment bracket fixedly attached to the mower body, front and back pivot assemblies operatively connected to the axles of the mower, a control rod connecting the front and back pivot assemblies, an adjustment lever, and a lift assisting torsion spring. To adjust the position of the mower blade relative to the lawn, the operator moves the adjustment lever causing the back pivot assembly to raise or lower the back wheels relative to the mower body and causing the front pivot assembly to raise or lower the front wheels relative to the mower body.
