Innovative Remote Over Center PTO

Innovative Remote Over Center PTO


For nearly a century, Twin Disc has been the industry leader in power take-offs. Adding to its arsenal of rugged-duty products, the company introduces its RO 111/211 “Remote Over Center” PTO. This groundbreaking unit leverages a patent-pending design to remotely engage the over-center mechanism in the time-proven, best-selling Twin Disc SP 111/211 PTO.

When complex machinery configurations or location hinder easy access to activation, the RO 111/211 can be engaged and disengaged remotely via a control valve and/or electronic control. Hydraulic or pneumatic actuation is achieved through ports, making access to the fittings uncomplicated and straight-forward.

Hydraulic or pneumatic pressure is required only to engage or disengage the PTO, the fluid or air supply can be shut off when not needed. Without the constant hydraulic or pneumatic flow of other designs, the unit is far more efficient and cost-effective than that of its competition.

The RO 111/211 is dimensionally identical to Twin Disc’s current mechanical SP 111/211 and continues to utilize one 11’ friction plate in the 111 and two plates in the 211. Existing SPs may be field converted to and RO using kits available from the company.

The advanced design of the PTO allow for side load and inline applications. External cooling, filtration or a rotary union are not needed. Build strong to last, the RO 111/211 excels in a wide range of industrial applications including agriculture, construction, manufacturing, marine, mining, timber and oil and gas production. The units are installed OEM and in customs settings.

Generations have relied on Twin Disc to provide tough and reliable power products for use in the most grueling work conditions. For close to a century, the company has remained a leader in designing and manufacturing the most innovative heave-duty industrial equipment. Its line-up includes power-shift transmissions, power take-offs, gearboxes, torque converters, pump drives, air clutches, electronic shift controls and universal control drives.
