What Are PTO Shafts for a Tractor PTO?
A PTO shaft provides power to a motor, usually a chain or a hydraulic cylinder.
These shafts are available in different sizes and shapes and are designed to withstand pressure, impact, and tension.
Some of these shafts feature a slip clutch or shear pin to protect against common obstacles.
Check out the selections below if you're looking for a new PTO shaft.
They can be used with different implements, such as tractors and lawn mowers.
The Power Take-Off (PTO) shaft is responsible for transferring mechanical power from a tractor to various farm equipment.
Whether you use a rotary tiller or a mower, a tractor PTO shaft will control the power and speed of the device.
This mechanical driveline is a crucial part of your tractor and will not run without it.
A damaged PTO shaft will result in a breakdown of the machine.
PTO shafts experience high levels of stress during operation.
While designed to handle high loads, they can fail for various reasons.
Signs of failure can be found on tractors, implements, and connecting shafts.
In some cases, the failure of a PTO shaft can be caused by a compression of the shaft.
Shortening the PTO shaft will require a significant amount of experience.
Contact a professional if you are not confident in your ability to shorten a PTO drive shaft.
There are many different types of PTO units available on the market.
Some are rated for continuous or intermittent torque.
Different models feature different PTO shaft rotation to engine RPM ratios.
A typical PTO shaft has six splines, while a dual PTO has twenty splines.
A dual PTO allows the same engine to run at both speeds at the same time.
If you're looking for a Dual PTO, choosing a unit with multiple splines is best to increase its versatility.
Choose one with a patented lever release when shopping for a PTO shield.
You'll find operating easier if you use the universal fit PTO shield by BARE-Co.
The shields are two sizes based on the shaft's yoke-bearing groove diameter.
Smaller shields are suitable for yoke-bearing grooves that are one-fifth to two inches wide.
Bearings are included with each shield.
Most PTO shaft failures are caused by improperly adjusted clutches.
Excessive work angles can also cause damage to the yoke ears.
Extreme angles can also lead to premature ware of shield bearings, so lubricate the PTO shaft at least once every eight hours.
It's a good idea to check the yoke for excessive angles if you have any doubts.
Some engines have multiple models of PTO shafts for different applications.
For example, a semi-permanently mounted power take-off is located on a marine or industrial engine.
These engines use a drive shaft to power secondary implements and accessories.
Aircraft applications also include accessories drives.
Jet aircraft, for example, have four types of PTO units.
A power take-off shaft is the most efficient for mowing, shredding, and other purposes.
