Abstract
A self-propelled mower having a forwardly projected power unit containing a motor and mowing assembly, the deck is rotatably mounted on the axle of the machine so that the mower assembly can be raised and lowered in reference to the ground. The mower contains a riding unit mounted behind the axle. A linear actuator is secured to the riding unit that has an extendable rod which is coupled to the power unit by a pivoted link. The power unit is placed in a mowing position when the rod is extended and in an elevated position when the rod is retracted. The actuator is driven by a reversible electric motor that is controlled by a switch mounted upon the steering control of the mower so that the operator can raise and lower the mower without releasing the steering control.
