MOWING MACHINE BRAKE APPARATUS WITH SLIDEABLE ENGAGEMENT

摘要

A brake apparatus for a mowing machine that includes a brake gear operatively rotatable with a rotatable member and a lock assembly for meshing with the brake gear to restrict rotation of the brake gear. A guide rail assembly is fixable relative to a support for supporting the rotatable member for rotation. The guide rail assembly guides a lock assembly movable between an unlocked arrangement and a locked arrangement. An actuator plate and the guide rail assembly jointly engage the lock assembly to effect meshing and unmeshing of at least one engagement member of the lock assembly, such as a roller or a jaw member, with the brake gear. The actuator plate is selectively rotatable about an axis of rotation of the brake gear relative to the guide rail assembly, where rotation of the actuator plate effects movement of the lock assembly between the unlocked and locked arrangements.
