Parker Chelsea’s 870 Series Hydraulic Power Take-Offs are known for its power-dense design. The 870 Series PTO for Allison automatic transmissions features a compact housing that eliminates clearance issues and employs robust moving parts to ensure high performance. It is available only for 10-Bolt applications that have a high torque requirement and a demanding workload. This PTO solution offers two assembly arrangements to maximize installation clearance. High-capacity bearings and superior gear designs provide torque ratings up to 670 lbs-ft for the ultimate performance. There is no need to de-rate the PTO for continuous applications. The continuous torque rating of the 870 series PTO reduces the likelihood of failure as the PTO is no longer the weakest part of the system which will reduce the external spend on field service.

The 870 Series 10-Bolt powershift PTO features six shift options, four of which are integrated into the PTO housing that require one hose for a simplified installation - the hose is included with the PTO. Our popular Electronic Overspeed Control (EOC) is also available to protect the PTO and driven equipment. Eight internal gear ratios provide a wide variety of speeds to meet virtually all application requirements. Direct mount pump flange options are also available with our Wet Spline Technology that provides increased PTO and pump shaft life. Versatility, power, ease of maintenance and installation make the 870 Series the BEST choice for Snow & Ice, Refuse, Aerial, and Defense truck requirements.
