The new 590 Series PTO from Parker Chelsea provides maximum power with a compact design, according to the company. The coaxial designed rear-mount PTO has a compact housing that helps eliminate clearance issues and was designed specifically for the new Allison TC10 transmission. High capacity bearings and superior gear designs give torque ratings up to 660 ft/lbs, or 900 Nm, for the ultimate performance and there is no need to de-rate the PTO for continuous applications. The 590 Series is a clutch pack design which allows for easy engagement with no gear clashing. The four direct mount pump flange options come standard with our Wet Spline design and provide increased PTO and pump shaft life.
