PTO Overrunning Clutch

1-3 / 8 male X 1-1 / 8 female.
The unit is connected to the PTO output of the tractor through a rolling pin. Simply remove the grease fitting and install the roll pin through the hole on the tractor PTO shaft.
This is a high-quality unit. It is the same as those sold by TISCO, TSC, and other companies. There are other units with higher costs, which is the quality of the lessor. See below for its location. We also have a quick-release PTO version.

The simplest and earliest form of PTO is the transmission of PTO. The PTO shaft is connected to the transmission of the tractor. The PTO only works when the tractor clutch is released, so if the tractor is engaged during deceleration, the PTO will stop working, which is a disadvantage in applications such as mowing.
The transmission PTO usually requires an overrunning clutch. Without it, the driven equipment (such as the lawn mower blade) will exert a force on the PTO shaft and then change speed due to inertia. The equipment will “drive” the tractor, and you can still move after using the tractor’s transmission clutch. The overrunning clutch prevents this by allowing the PTO shaft to rotate freely in one ion. In newer models, this is built into the tractor. In older tractors, it is an additional device mounted on the PTO shaft. Overrunning clutch 1-3 / 8 external thread x 1 1 / 8 internal thread.

Overrunning PTO Clutch for Tractor

The overrunning PTO clutch is a device that allows the tractor’s power take-off (PTO) shaft to drive in one direction but rotate freely in the other direction (flywheel). The ratchet mechanism in the overrunning clutch is similar to the flywheel hub on a bicycle. The flywheel action of the overrunning clutch prevents the device from “driving” the tractor through its PTO shaft.
A typical example is a rotary mower (sometimes called a “Bush mower”), which operates behind a tractor with a transmission PTO. When the operator pushes the clutch to decelerate the tractor, the inertia of the rotating mower blade applies force to the PTO shaft. This force drives the tractor forward, causing an unsafe situation.
Overrunning clutch quick coupler some tractors with a transmission connected PTO shaft have an internal overrunning PTO clutch provided by the manufacturer. For tractors without clutches, many companies produce after-sales overrunning clutch mechanisms. A typical device is a quick coupler clamped on the tractor PTO shaft between the tractor and the equipment.

What does PTO overrunning clutch do？

This convenient small clutch slides on the existing PTO shaft of the tractor (six spline shafts protruding from the rear of the tractor). After pressing the clutch pedal, the rotation momentum of the mower will be kept, and the tractor will not be “pushed.” Installation takes about 20 seconds. If you use a lawn mower (all Myanmar) on a tractor without an active PTO, this is a “must-have.”
Want to be more professional? Without one of these clutches – when you go out to mow and press the clutch pedal, the mower will continue to rotate due to the rotational momentum of the blade. A lot of momentum is stored in the rotary mower. Since there is no disconnection between the PTO and the transmission, this momentum continues to rotate the transmission gears, and you continue to move forward. Many customers call to order these clutches after rushing into the garage door, the car, the tree, etc. When the clutch is pressed, the tractor will continue to drive, which is terrible (and dangerous). You can apply the brake, but it still takes a few seconds to stop, which is very difficult for the transmission due to the low gear. You will continue to move forward until 1 – shift the PTO or transmission to neutral (which is difficult to do in an emergency stop) or 2 – the mower stops rotating.
The overrunning clutch acts like a ratchet. Do you know how you turn the ratchet wheel hard in one way to tighten the bolt & then it turns quickly in another way? The same is true for the overrunning clutch. It allows the tractor to apply power to rotate the mower, but the mower cannot use its momentum to rotate the transmission. After installation, you can press the clutch & the tractor will stop immediately, but the mower will gradually rotate to a safe stop. For example, you can press the clutch to shift, and the mower will continue to rotate freely. This makes it easier to resume mowing because you do not have to rotate the mower from the entirely stopped position again.

How to install PTO overrunning clutch

1) Remove the grease fitting from the clutch.
2) Rotate the inner drive sleeve to align the holes in the drive sleeve With the oil nozzle mounting hole.
3) Install the clutch on the tractor so that the oil filler’s mounting hole is aligned with the hole through the tractor PTO shaft.
4) Align the oil filling holes on the tractor PTO shaft and install the Spring pin.
5) Test installation: when the clutch rotates clockwise, It should override the drive shaft. When turning counterclockwise Direction, which should engage the PTO shaft
