ABSTRACT:
A lawn mower service lift has a mower supporting frame mounted for pivotal movement between raised and lowered positions on a base frame by a parallelogram linkage. A stop rail maintains the support frame in the raised position by abutting the parallelogram linkage in an over center position. The supporting frame lies between parallel side rails of the base frame which serve as a guide track to properly align a lawn mower on the supporting frame. The device is useful in performing repair and maintenance on push-type rotary lawn mowers.
