Safety Hitch Pin
A positive-lock safety hitch pin, developed and patented by Iowa farmer Gary Goodlove, of Palo, uses a large cotter pin to lock and hold it in place. But unlike conventional safety hitch pins, this one `s differentù the locking pin is on top rather than underneath the drawbar.
"Hitching is much safer with this top-side locking pin," explains Goodlove. "Corn stalks and other debris can't strike it and bounce it out."
Goodlove adds that, when tandem axle rigs are pulled over heavy trash, the problem of hitch pins bouncing out is compounded. "Tandem axle equipment increases the vertical thrust on the drawbar, causing the tongue to bounce and thus increase chances that the pin might bounce out. This can't happen when the locking pin is positioned on top the drawbar."
The 6 in. long pin `s pivoting handle hinges at the top and its bottom end inserts through a hole at the bottom of the pin. The configuration is' self-locking in itself but "foolproof" locking for all situations is virtually assured by inserting the large cot-ter pin through the top-side hinge so the locking handle can't pivot, Goodlove points out.
Available with 3/4 in. dia. pin ($9.95) and 7/8 in. dia. pin ($10.95).
