Abstract: A support apparatus adapted for use with a riding lawnmower. The support apparatus is configured to assist a user in mounting, dismounting, and provide stability while operating the riding lawnmower. The support apparatus comprises a pair of ergonomically shaped support legs and a crossbar member connecting the pair of support legs at one end of each of the support legs. Each of the pair of support legs is attachable to a platform of the riding lawnmower via a mounting plate. Each mounting plate is perpendicularly attached to an opposite end of the respective support leg as the crossbar member.
