Abstract
According to an embodiment of the disclosed subject matter, a lift assembly for a lawnmower can include a mower housing configured to house blades for cutting vegetation. A frame can be located above the mower housing, the frame including two longitudinal extending frame members, and at least one pivot bar extending between the two longitudinal extending frame members. A linear actuator can be located adjacent the frame members and connected to the pivot bar such that actuation of the linear actuator causes the pivot bar to rotate about a rotational axis of the pivot bar. At least one cam can be connected to the pivot bar so as to rotate with the pivot bar, the cam including a mower housing attachment element that supports the mower housing such that rotation of the cam varies a distance between the frame and the mower housing.
