How does PTO work?

A PTO transfers power from an engine to another piece of equipment or machinery that does not have its own engine or motor. Power is transmitted through the drive shaft.
The tractor’s PTO shaft transmits power from the tractor to the PTO-driven machine or implement. The drive shaft is connected from the machine to the PTO shaft of the tractor. The PTO and drive shaft rotate at 540 rpm (9 times per second) or 1,000 rpm (16.6 times per second), significantly faster than our reaction time

What is a PTO shaft?

A power take-off (PTO) shaft is a mechanical device used to transfer rotational power and torque from the engine (usually through a transmission) between the tractor and implements or accessories. Early PTOs were primarily driven by a transmission located at the rear of the tractor – this allowed easy access to the output shaft.
There are two main types of freestanding PTOs; mechanical and hydraulic.

How Long Will It Take to Get My Drive Shaft?

We understand that time is money for most of our customers, so we strive to provide the fastest turnaround time on our farm shafts.

Agricultural drive shafts require a great deal of attention, and safety is very important when operating any and all drive shafts. We will be able to provide you with an appropriate turnaround time estimate when you submit your order. We will notify you of any potential obstacles that could affect the readiness time of your farm drive shaft, such as parts availability and shipping times. Also, we will give you a quote before your propshaft is complete.

What Can We Provide

Our line of PTO shafts are available in a variety of lengths. These are rated for compact tractors and machinery. Length is measured by the overall length of the drive shaft when closed. Safety bolt and slip clutch (torque limited) PTO shafts are also available. These stop the drive from the tractor to the machine during overwork and are popular in rotary machines and other ground care equipment. All axles can be extended to a certain extent to accommodate different tractor attachments; lawn mowers, topping machines, rotary machines, etc.
