Abstract
A power take-off (PTO) is used to selectively run a secondary device. The PTO includes a clutch assembly having first and second clutch members that are selectively engaged with each other to drive the secondary device. The first clutch member is associated with a driving input and rotates at an input speed. An accumulator is in power communication with the secondary device and is used to provide power to temporarily drive the second clutch member via the secondary device such that a speed of the second clutch member can be synchronized with the input speed for clutch engagement.
