<p>A transaxle (12) including a self-adjusting brake mechanism. The transaxle includes a housing (14) and a speed reduction mechanism including a plurality of interconnected shafts (22,23) rotatably disposed in the housing. A brake assembly (38) is mounted on the housing (14) for applying braking force to one of the shafts (22,23), the braking mechanism including a threaded mounting member (50) and a brake lever (40) having an opening rotatably disposed around the threaded member (50). An adjustment nut (54) is threadedly disposed on the mounting member (50) and has a portion thereof disposed within the brake lever opening, the adjustment nut (54) operable when rotated in a given direction to adjust the brake (38) to compensate for wear. The brake lever opening has a pawl (74) that cooperates with a plurality of ratchet teeth (83) on the adjustment nut (54) to adjust the brake mechanism for wear. <IMAGE></p> |
