All-Mechanical Automatic Hitch Pin

All-Mechanical Automatic Hitch Pin HITCHES Hitches 19-5-12 Here's one of the slickest automatic hitch pins you'll ever see. It's called the "Drop-Pin Hammerstrap" and was invented by Brian Olson, inventor of the hydraulically-operated Olson Power Pin previously featured in FARM SHOW. "It's all mechanical with nothing to wear out on it," says Olson. "The operator just backs up into the drawbar and watches as the pin automatically falls into place." The Hammerstrap bolts to the top of the existing tractor drawbar (you drill holes into the Hammerstrap to match the draw-bar holes). It's designed to be used with Olson's "Perfect Hitch", which bolts onto the front of the implement tongue. To set the pin for automatic hookup, the operator lifts the drawpin up, allowing a handle on the drawpin to rest in a cradle. When the tractor driver backs up to the implement, the nose of the implement hitch hits a trigger that pushes the drawpin handle out of the cradle. The drawpin then drops down through the tractor drawbar and the handle comes to rest in a depression at the back of the Hammerstrap, where it keeps the drawpin in place. "The only way the drawpin can come out is when you lift the handle and pull up the pin," says Olson. The round front part of the Perfect Hitch adapter fits into a round alignment cup on the Hammerstrap so you don't have to be dead center when you back up. The Drop-Pin Hammerstrap sells for $179. The Perfect Hitch sells for $100. Contact: FARM SHOW Followup, Power Pin, Inc., 3018 Gordon Road, Regina, Sask., Canada,S4S 2T8 (ph 306 525-8833).
