Abstract
A blade brake assembly is provided for use with a lawn mower having a self-propelled power deck with a pair of drive wheels and a mower deck supporting at least a mower blade driven by the power deck. In order to change the cutting height, the mower deck is pivotable with respect to the power deck. The blade brake assembly includes an actuator mounted to the power deck and shiftable in response to a brake command by an operator, a band brake operatively coupled to the mower blade, a center pivot mounted on the mower deck and fixed with respect thereto, and a pivot lever pivotally mounted on the center pivot and having a first end pivotally connected to an end of the actuator. Furthermore, a link member is pivotally connected at one end thereof to a second end of the pivot lever, opposite the first end, wherein the center pivot is intermediate the two ends of the pivot lever, and wherein the link member is connected at the second end thereof to the band brake.
