PTO Link® HD – Safety Plunger Pin (SLIC Pin™)

The PTO Link® Safety Plunger Pin (SLIC Pin™) also known as the Quick-Release SLIC Pin is truly one slick pin! SLIC is an acronym for Self Locking Implanted Cotter Pin, and as the name implies, it is a pin and cotter all in one! This one-piece locking clevis pin is fast and secure. It also acts as an alignment pin for the two mating couplers of the PTO Link® system and further secures the couplers (much like a dead bolt lock) to withstand most high torque scenarios or instances wherein reverse torque on the PTO shaft could possibly be experienced (e.g., while using flex-wing mowers, heavy duty shredders, tillers, augers, stump grinders, PTO auto-brakes or reverse safety switches etc.). Since these high torque or reverse torque scenarios on the PTO are often unforeseen, it is therefore required to always install the safety plunger pin during use of the PTO Link® system.

The PTO Link® system already comes with a replaceable spring-loaded locking pin affixed onto the tractor (female) coupler that engages with the implement (male) coupler for the initial connection. The Safety Plunger Pin (included standard in all system packages) provides the following benefits:

  1. Snugly aligns and secures the male and female couplers of the PTO Link® system together to minimize vibration and wear to your driveline;
  2. Balances and absorbs excess torque across the entire coupler diameter of the PTO Link® system, providing added strength to your PTO connection during high torque or reverse torque scenarios.
  3. Provides enhanced safety, protection and durability to your PTO Link® system.

The Safety Plunger Pin features a strong, spring-loaded plunger that functions as an easy insertion wedge. The wedge plunger retracts when inserted, then springs back up when through the joined couplers. The vertical face at the rear of the plunger prevents backing out and locks the pin into place!

Installation instructions: Prior to installing the plunger pin, first install the PTO Link® couplers each separately on the tractor’s PTO (female coupler) and implement shaft receiver (male coupler). Next, couple the male and female couplers together, aligning the studs of the male coupler into the openings of the female coupler. Then slightly rotate the male coupler counter-clockwise (or the female coupler clockwise) until the two connected couplers are fully mated and the stainless steel spring loaded locking pin has fully engaged. Now, note the aligned 1⁄2” opening through both couplers of the fully mated PTO Link® system, positioned across the coupler, opposite the stainless steel spring-loaded locking pin. To install the safety plunger pin, place tip of the pin into the 1⁄2” opening on the tractor coupler. With the head of the safety plunger pin always facing the tractor, push the pin through the aligned 1⁄2” openings on both couplers. The wedge of the plunger pin (now emerging from the implement side coupler) will release its internal spring and secure both couplers together.

To uninstall, just depress the wedge plunger and push the end of the pin toward the tractor. Then, pull the head of the emerging pin through the couplers from the tractor side, releasing the pin from the mated couplers. Once accustomed to the Safety Plunger Pin, your process to reinstall and uninstall will take only a few seconds. When the PTO Link® system is not in use, affix the safety plunger pin through the 1⁄2” opening on the tractor coupler for convenient storage.
