Cab Operated Hitch For Tractors
"We think it's better and safer than any other automatic hitch system on the market," says inventor Brian Olson, a Tompkins, Sask., fanner. "You don't need help and you don't have to leave the cab to hook or unhook implements. And, by moving all hydraulic hoses to a manifold type hookup within reach from the rear window, you can make the entire hookup ¨hitch and hydraulics ¨ without leaving the cab."
Brian's initial prototype was a hydraulically-operated version which we told you about in FARM SHOW last fall (Vol. 12, No. 4, 1988 issue). Since our report, Brian has developed a lower cost, hand operated, cable controlled model that sells for $290. Called the Power Pin, it's patented and comes equipped with a "lift ramp" that automatically lifts and guides the tongue of an implement into position for hookup with the Power Pin, which is activated manually from inside the cab.
The hitch for Deere tractors attaches with 8 bolts and requires no cutting or drilling of holes and mounts below the drawbar so it doesn't interfere with a pto or the swinging drawbar. If you're stuck in the field and the 1-1/2 in. dia. hitch pin binds tight in the hole, you can unlock the control lever in the cab and manually pound the pin straight down to remove, it. The pin, which enters from the bottom, has a smooth base to eliminate trash accumulation.
"The agricultural industry standard of the future will be single tongue' implement hitches and double tongue tractor drawbars. Some older implements still have the double tongue, which the Power Pin can work on with the use of the top tractor drawbar hole. To achieve a single tongue standard on my farm equipment, I removed one tongue and welded it to the other tongue, thus keeping the same amount of steel in the hitch," Brian points out.
