Abstract
A mower cutting unit lift system includes a rotary motor connected to a power supply and turning an output shaft connected to a bell crank. A flexible link between the bell crank and a lift arm is used to lift a cutting unit to a transport position if the rotary motor turns the output shaft and the bell crank in a first direction, and lower the cutting unit to a mowing position if the rotary motor turns the output shaft and the bell crank in a second direction.
