Chelsea 859 Series

8-Bolt, High Torque Capacity



The versatile 859 Series is a shiftable P.T.O. that exceeds the torque capacity of an 8-Bolt P.T.O. while offering the tighter sealing of a 10-Bolt pattern. The 859 Series is an excellent choice for market applications requiring greater torque such as fire and rescue, refuse, and oil field exploration. It is available in five-speed ratios and multiple output types, along with a rotatable shift valve option, including Chelsea’s popular 360° rotatable flange.



Seven (7) speed ratios and Six (6) output options

Electronic Overspeed Control available to protect driven equipment from overspeeding.



No Backlash to set
