Rubber Block Drive PTOs
This special purpose PTO is intended for heavy-duty applications not requiring a cut-off clutch. The need for a flywheel pilot bearing has been eliminated in some models. Twin Disc's proven rubber block drive absorbs the minor misalignment usually found between the engine fly-wheel and the PTO connecting member. Depending on the load to be transmitted, a single or double row of rubber blocks can be used.
Straddle Bearing PTOs
The Straddle Bearing PTO was explicitly designed for high horsepower, high side load, heavy duty applications. Rugged benefit features include cast iron housings, cylindrical roller bearings, nodular iron drive ring and ball bearing throw out collar. Unique style sheave housing easily accepts a 14" diameter 10 groove sheave, This sheave housing allows for belts to pass inside and/or outside of housing. Housing versatility also allows for repositioning. Additionally, the need for an engine mounted pilot bearing has been eliminated.
