1. Choosing the Right Hitch Pin for Your Tractor
Selecting the correct hitch pin is non-negotiable for safety when towing or operating heavy implements. A pin that is too small for the hole will vibrate and eventually shear, while a pin that is too large simply won’t fit.
At Jrs Farm Parts, we manufacture heavy-duty hitch pins designed to meet the rigorous standards of American and International tractor categories. Whether you need a standard red handle hitch pin or a custom-designed forged pin, understanding the sizing standards is the first step.
