Abstract:
1. A caster wheel locking system for a walk-behind mower comprising: a mower deck supported by a pair of front caster wheels and a pair of rear wheels, and a handle attached to the mower deck; a traction drive bar connected to the handle and moveable between a neutral position and a forward drive position in which the pair of rear wheels rotate to propel the mower forward; and a caster wheel lock on each of the front caster wheels which locks the front wheels and aligns the front caster wheels in a forward direction, a cable from the caster wheel locks linked to the traction drive bar, and a caster control lever attached around an upper end of the cable to vary the tension on the cable to either lock the front caster wheels in a forward direction regardless of the position of the traction drive bar, unlock the front caster wheels regardless of the position of the traction drive bar, or lock the front caster wheels if the traction drive bar is in the forward drive position, and unlock the front caster wheels to allow the front caster wheels to steer freely if the traction drive bar is in the neutral position.
