Power takeoff for tractor having parallelogram front wheel suspension
A tractor having a rigid frame under which a mower can be carried longitudinally intermediate rear driving wheels and steerable front wheels. The tractor comprises an engine mounted on a front portion of the frame, a rigid laterally extending support member near the front end of the frame, laterally opposite wheel supporting brackets, one pivoted to each end portion of the support member to swing about a longitudinally extending upper axis. The tractor also comprises a laterally extending link pivoted to each of the brackets on a lower axis that is below and parallel to the upper axis to cooperate with the support member in connecting the brackets in a parallelogram linkage, and an axle member for each bracket having a laterally inner portion pivoted to the bracket to swing about a substantially vertical axis and having a laterally outwardly extending axle portion on which a front wheel is rotatable. The tractor is characterized by: A. a tubular bushing secured to the support member intermediate the ends thereof with its axis extending longitudinally; B. a power takeoff shaft coaxially rotatable in the bushing having opposite end portions that respectively project forward and rearward beyond the bushing; C. a laterally extending hitch support having means near its opposite ends for detachable connection to it of forwardly projecting hitch members of a mower; D. a sleeve secured to the hitch support intermediate its ends and surrounding the bushing to pivot the hitch support for tilting about the axis of the bushing; E. a connection between the link and the hitch support whereby substantially lateral motion of the link imparts tilting motion to the hitch support; and F. a driving connection between the engine and one of the end portions of the shaft.
