ABSTRACT:
An apparatus wherein a self-propelled tractor mounts a support plate, a spool, and a reversing motor mounted to the spool to effectively extend and retract a cable wound about the spool. The cable is directed forwardly to a mounting plate positioned rearwardly and coextensively of a rear edge of an associated lawn mower housing to permit extension and retraction of a lawn mower about an incline of an associated slope in use of the lawn mower. A modification of the invention includes a plurality of spools, each including a reversible motor mounted in association with each respective spool to permit steering of each spool by selective relative rotation of each spool.
