Abstract
Steering sulkies of the present invention are based upon the 'crank/steering-rod' mechanical principle but provide profound refinements thereover. Cranking is provided at first and at second stations. At the first cranking station, preferably overlapping left-link and right-link effect simultaneous rotation of the two sulky wheels about their transversely separated vertical axes in response to towing vehicle steering; such first crank is contingently abuttable against blocking stops to prevent sulky jackknifing. The second crank, which is co-rotatable with the first crank, is connected to the rearward end of elongate steering-rod that herein intersects the frame longitudinal-axis before being terminally connected to a frontal hitch. A preferred hitch provides a convenient, reliable, and multi-directional flexural connection between a lawn-mower or other towing vehicle and the trailing self-steering sulky.
