Abstract: A towed implement includes apparatus adapted for being driven by a power take-off shaft of a towing tractor. The implement includes a tongue having a hitch bracket at its forward end, the bracket incorporating a ball coupler. A hitch adapter is provided for coupling the hitch bracket to a three-point hitch of the towing tractor, the adapter including a hitch bar connected to the ball coupler by a pin. The implement includes a power transmission assembly separate from the hitch adapter and including identical first and second right angle gear boxes, with the first gear box being rigidly fixed to the tongue and the second gear box being drivingly coupled to the first gear box along an axis passing through the ball coupler and about which the second gear box may rotate.

Abstract: A hydrostatic drive for a windrower includes wheel motors having speed control arms movable between "hi" and "lo" speed stops by means of a pair of push-pull cables coupled between the control arms and a speed control lever. The cables have housings mounted to the motor control arms so as to isolate the cable from noise and other vibrations induced in the control arms. The cable housings are also mounted to the frame by a shock absorber load assembly which acts through the cable housing to resiliently bias the control arms against their respective stops and to further isolate the cable from vibrations.
