The Twin Disc Inc. RO 314/311 "Remote Over Center" PTO remotely engages the over-center mechanism in the SP 314/311 PTO and is complementary to the previously released RO114/RO214.

The RO 314/311 can be engaged and disengaged remotely via a control valve and/or electronic control when machinery configurations or location hinder easy access to activation. 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's clutch operation is far more efficient and cost-effective than that of its competition.

The RO 314/311 is dimensionally similar to the current mechanical SP 314/311. It continues to utilize three 14 inch friction plates in the 314 and three 11 inch plates in the 311. Existing SPs may be field converted to an RO using kits available from Twin Disc. The advanced design of the PTO allows for side load and inline applications. External cooling, filtration or a rotary union are not needed.
