The 540/540 economy PTO allows operators to select the engine rpm for reduced fuel consumption, reduced noise levels, reduced vibration, and less wear and tear on the engine, while at the same time keeping the proper 540 rpm at the PTO.
The economy PTO provides 540 rpm to the PTO at 1705 engine rpm. The 540 economy mode is ideal for any PTO application, for running a thresher, straw reaper, and other applications where full engine horsepower is not required.
Operating at lower engine rpm decreases fuel costs up to 30 percent and provides additional productivity by improving the operating experience through enhanced operator comfort from reduced noise and vibration.
A lever allows the operator to simply change between 540 and 540E when conditions merit the opportunity to save fuel without affecting performance.
For heavy-duty operations requiring maximum PTO power, the PTO shift lever is placed in the 540 position, the PTO is engaged, and the engine is run at a rated speed of 2400 rpm. This selection gives 540 rpm to the PTO shaft and delivers the fully advertised horsepower at rated engine speed.
When the tractor is in economy PTO mode, the engine is electronically limited to 1705 rpm, preventing accidental over-speeding of PTO implements and protecting against binding the PTO shaft.
This interlock also prevents accidental shifting of the PTO selector lever at engine speeds above 1700 rpm, which would lead to downtime for fixing implements or drivetrain components.
