: Over-running clutches provide a safe means to protect operators and high-priced machinery from circumstances when the inertia of PTO motivated put into action exceeds and over-works the tractor PTO quickness. In such a case, the over-working coupler will free-wheel
smoothly and safely. Over-running clutches will normally resist applications requiring up to 65 h.p. at 540 rpm and 100 h.p. at
1000 rpm. Severe shock loads or travel line angularity will reduce this capability
If the distance of your PTO does not fit properly within a tractor, a PTO adapter can extend the size without needing to replace it for a new one. This adapter has an overall amount of 7-3/16″ with a male end 1-3/8″ x 6 spline and a female 1-3/8″ x 6 spline end.

The over-running coupler can be an essential part of PTO travel on rotary mowers, bailers, hay conditioners or any implement where inertia of driven unit could be required to over-run driving source. The coupler drives solidly from tractor to put into action and free wheels efficiently when implement exceeds tractor PTO speeds. All measurements are nominal.
Converts a 1 1/8″ keyed spline to a 1 3/8″ 6 spline.
Expected with 1000 RPM gearcase upgrade or Three Point Hitch system for the 25PTOC.
