Tractor Drawbar Clevis on PTO Driven Implements

Clevis Hitches—A tractor drawbar equipped with a clevis hitch (hammer-strap) can cause interference with the PTO driveline IID [Implement Input Driveline]. This interference can cause serious damage to the IID guarding and the IID telescoping members. The clevis hitch on the tractor must be removed.

ADMA recommends that a warning note and sketch be placed in the Owner’s Manual similar to the following:

If this implement is attached to a tractor with a clevis hitch (hammer-strap) style drawbar, the hammer-strap must be removed to prevent damage to the IID guarding and the IID telescoping members. [See Figure 1]

If this implement is attached to the tractor with an offset in the drawbar, be certain it is in the down position to prevent damage to the IID guarding and the IID telescoping member. [See Figure 2.]
