One of the best features about tractors is the versatility of the trunk end. The powerful diesel engine has an end result shaft on the trunk coming out of the 3 point hitch known as the Power REMOVE or PTO. That is an engineering foresight which will be difficult to match. With the invention and wide implementation of this single feature, it gave tractors the ability to use three level attachments that had gearboxes and additional turning elements without adding an external power source or alternate engine. While the diesel engine that powers the forward movement of the tractor spins, it turns this PTO shaft driving tillers, mowers, sweepers, and several other attachments that really crank out the horsepower and complete the job. When searching at PTO shafts, you need to understand the forces that are put on these essential parts and the safety mechanisms that must be in location to protect yourself and your investment. The very first thing you notice when looking at a PTO shaft is the plastic-type sleeve that encases the complete amount of the shaft between the tractor and the attachment, the steel shaft is in fact turning within this easy protective casing, stopping curious onlookers from grabbing a high horsepower turning shaft and really doing some damage to their hands and arms. The next matter you might notice may be the bolts and plates that can be found at one end of the shaft, these bolts and plates will be the automatic pressure relief program that manufacturers placed on them release a pressure if for example a tiller digs partially into hard floor that it could not power through, 1 of 2 things may happen, the slip-clutch will engage and absorb the majority of the excess energy, or the “shear” bolt will break off permitting the PTO to carefully turn freely while disengaging the energy going to some of the working parts of the attachment. Tractor PTO shafts come in varying sizes, to truly get you close to the specific size of shaft that you’ll need for your unique purpose, but almost all PTO SHAFTS REQUIRE Slicing FOR PROPER FIT!
A electrical power take-off (PTO) shaft transfers mechanical power from a tractor to an implement. Some PTO-driven gear is managed from the tractor seat, but many types of farm products, such as elevators, grain augers, silage blowers, and so forth, are operated in a stationary job, enabling an operator to leave the tractor and move around in the vicinity of the put into action.

A PTO shaft rotates at a speed of either 540 rpm (9 rotations per second) or 1,000 rpm (16.6 rotations per second). At these speeds, a person’s limb could be pulled into and covered around a PTO stub or driveline shaft many times Tractor Pto Drive Shaft before the person, even a person with extremely fast reflexes, can react. The fast rotation rate, operator error, and insufficient proper guarding help to make PTOs a persistent hazard on farms and ranches.
