PTO Shaft

We get a lot of questions surrounding PTO shafts and how to attach them to your tractor. In today’s post, we’ll cover the basics of PTO, PTO Shafts, and PTO adapters for your tractor mounted implements. 

Spoiler alert: Yes – PTO shaft is included with all tractor implements purchased from Victory Tractor at!

What is PTO?

PTO stands for “Power Take-Off” and is the primary mechanism for providing power to an attachment or implement (such as a flail mower) via PTO shaft.

By providing rotational energy through the driveshaft (or cardan shaft) a variety of tractor mounted implements can be operated by small and mid-sized tractors.

What is a PTO shaft?

A PTO shaft transfers the power from the tractor to the PTO powered attachment.  This enables the tractor to power a variety of tractor implements including flail mowers, wood chippers, rotary tillers, excavators, and more.

PTO shaft connectors on tractors are not standardized which can lead to complications when connecting the PTO shaft.  For example, some older tractor models have the connection flange closer to the tractor itself making it difficult to connect and lead to a potential safety hazard.

PTO Adapters

To avoid potential connectivity issues, you may want to consider a PTO Adapter for your tractor. The PTO adapter extends the connection to the implement, providing additional space for the PTO shaft to turn without touching the Arm Weldment or other parts of your tractor or the implement.

As a precautionary measure, it is a good idea to purchase a PTO adapter to ensure compatibility with your particular tractor model.

PTO Shaft and Adapters for Embankment Mowing

The PTO shaft included with all Victory Tractor mowers has a longer extension than the typical PTO Shaft.  The added length is necessary because of the far reaching movement of the mowers to the right of the tractor.

A PTO Adapter will be useful when operating Victory’s EMSD and EMHD Embankment Flail mowers.

The absence of a PTO Adapter could cause the PTO shaft to conflict with the arm weldment, which connects to the CAT I/II 3 point hitch.

How do I operate the PTO on my tractor?

Prior to running the PTO, you will need your tractor to reach the starting RPM (revolutions per minute).  Once the starting RPM has been reached you can begin operating the PTO.

Once the PTO has begun to power the attachment, steadily increase the throttle until you reach the operating speed.  The typical running RPM (revolutions per minute) for a tractor mounted PTO is 540 RPM, although there are tractor models that rev higher. 

Always refer to your particular tractor model for instructions prior to first-time use.

PTO Shaft Safety Tips

The most common PTO related injuries tend to occur when articles of loose clothing become entangled in the shaft. 

When operating the PTO, never reach over the shaft for any reason and avoid wearing loose-fitting clothing.

Injury can occur quickly, providing the operator little time to react, and in some cases resulting in death.
