A pivotable lever which may be pivoted into the path of advance of the starter pinion in a Bendix type starter as the starter pinion advances along a helical worm gear towards engagement of a flywheel is disclosed. The lever may be pivoted by means of a bowden wire arrangement, the opposite end of which is attached to the mower drive engagement mechanism or a linkage which moves therewith.
