The HOLLAND PH-990ST71 is an under-frame mount, pin coupler with a “fish mouth” style head and integrated rubber cushions for shock absorption at the coupling.

For severe off-road applications, reduce the above capacities by 25%.
The PH-990ST71 Coupler features:
Heat treated body and clevis pin for durability
Replaceable wear plates in “fish mouth” to minimize drawbar movement
