PTO and why you want it on your Work Truck

For over a century it was widely accepted that diesel engines were loud, noisy machines.  Adding a Power Take-Off (PTO) with its gears and hydraulic system seemed to amplify the rumbling sound of machinery at work.  Noisy engines and equipment were long considered normal by-products of work and construction sites, but governments in North America have been enacting laws to regulate the idling of diesel engines and help control noise pollution.  Portland Oregon is no exception when demanding cleaner quieter work trucks.  The Ford 6.7L Power Stroke V8 Turbo Diesel has many enhancements ( two stage combustion, structural integrity of the block, single turbocharger mounted to the engine block, etc.) for Noise?Vibration?Harshness improvements over the prior 7.3L diesel engine.  For that part, Chelsea Products division of Parker Hannifin must consider the noise characteristics of each new PTO design in addition to torque and speed requirements.  While we're on the topic of specifications, the pump flows up to 25.1 gallons per minute at 1200 engine RPM, providing 200 lb. ft. of torque (not coincidentally that PTO torque limit for a 6.7 diesel engine.) The goal is to achieve top-notch performance, yet so quiet that people will not be aware of the PTO from hearing it.


Features an output linked directly to the engine crankshaft providing “live” PTO operation anytime the engine is running, regardless of vehicle speed.  Provides the capability to power PTO-driven accessories, such as dump bodies, sprayer pumps, generators, salt spreaders and snowplows, with maximum flexibility.  Upfitter switches may be used as PTO control switches.  For more information contact Gresham Ford Fleet at 503.669.5343.
