Chelsea Products, a division of Parker Hannifin, has developed a family of 10-bolt side-mounted power take-off (PTO) units in conjunction with Caterpillar to operate on Cat's new CX series automatic transmission. This new PTO will offer up to six internal speed ranges, seven shift options, horsepower ratings from 63.6 to 109.4, and output options to meet the user's power transfer demands.
Also being developed by Chelsea are two new rear-mounted PTOs for the Cat CX series designed for superior clearance, reducing installation costs. These PTOs will provide a torque capacity that can handle front-mounted hydraulic applications but with the versatility of locating these applications at the rear of the transmission. Chelsea will offer one rear-mounted PTO that employs its Powershift design, allowing the operator a smooth, clash-free engagement of the unit. The second rear-mounted PTO will remain continuously engaged, making this unit a suitable option for variable-displacement piston pumps. Both PTOs are being tested on the CX series transmissions.
