| 68 | Horse driven hitch cart | US626717 | 1990-12-17 | US5071144A | 1991-12-10 | Baron L. Tayler |
| A horse-drawn hitch cart has its tongue adjustably positioned laterally, by means of a clevis and plural hand-actuable locking pins, along an apertured drawbar suspended forwardly and below the floor level of the cart frame to be rotatable about a laterally-extending axis. A yoke bar is attached to the distal end of the tongue by means of a yoke ring circumscribing the tongue between two longitudinally spaced and hand-actuable stop pins preventing the ring from being disengaged from the tongue. The proximal stop pin position is adjustable to accommodate different length horses by virtue of a series of through holes defined along the tongue rearwardly of the most distal stop pin. A clutch assembly, actuable from the cart floor by means of a lever, permits a ground driven power takeoff unit to be selectively engaged quickly and easily without requiring the driver to leave his seat. A bias spring and a mechanical stop acting on the lever prevent inadvertent engagement and disengagement, respectively, of the clutch. Selective lateral positioning of a towed implement is made possible with a three-point hitch unit modified to permit rotation between the drive arms and the sidelinks about respective axes disposed in vertical planes. | ||||||
