PTO Link HD Quick-Connect System - Safety Plunger Pin (Recommended Spare)(NOT Compatible w/Compact Systems)

INSTALLATION INSTRUCTIONS: Prior to installing the stand-alone Plunger Pin (grade 8 pin), first install the PTO Link couplers and then couple the male and female plates together. The final step is to install the Plunger Pin ONLY from the tractor side...so it secure through both couplers. (see more details in product description)
INSTALL PLUNGER PIN by inserting the pin through both couplers, starting from the tractor side, towards the implement side, the wedge of the plunger pin (now emerging from the implement side plate) will release its internal spring and secure both couplers together.
TO UNINSTALL: Depress the wedge tip and push the end of the pin toward the tractor. Then, pull the head of the emerging pin through the coupler from the tractor side, releasing the pin from the mated couplers.
QUICK INSTALL and REMOVAL (Pro-Tip): Once accustomed to the Safety Plunger Pin, the stand-alone one-piece locking clevis pin (grade 8 bolt), your process to install and uninstall will take only a few seconds for a quick and easy removal. PRO TIP: To remove any "side-load" pressure from the Plunger Pin...lift up slightly on the implement side coupler/shaft...which aligns the Plunger Pin holes for easier insertion, rotation and removal.
STORAGE: When the PTO Link system is not in use, affix the safety plunger pin through the 1⁄2” opening on the implement coupler for convenient storage. NOTE: a Plunger Pin (grade 8 pin) is included with every Tractor (Female) coupler. We RECOMMEND keeping a couple SPARE pins, since they are a stand-alone pin and can be easily misplaced while not in use. DIMENSTIONS: 1.5” L x 0.625” W
