Problems encountered in the use of PTO shaft

1. What if the PTO is not engaged but the PTO shaft is turning?

When the engine RPM rises above 1500, the shaft stops. However, when the engine speed drops below 1000 RPM, steering continues. While turning isn’t very hard, sometimes turning an attachment (whether it’s a pile hole digger or a winch) is enough.
You may have a bad clutch pack, but it’s unlikely to leak. It could also be a bad clutch pack brake disc that won’t stop the clutch. If this is the case, a visual inspection is required. Remember, the entire teardown will take place on the card.
Most likely, the PTO control valve is not properly adjusted, allowing it to only partially engage or float. A simple pressure test of the control valve will reveal if this is a potential problem. If the RPM is changing engagement, it may be a weak seal. When flow and pressure rise high enough, you experience shutdown. On the other hand, when flow and pressure decrease, it engages again.

2. Why doesn’t the PTO shaft turn after you engage the clutch and the PTO light comes on?

Your tractor model will be considered here, but we will provide some troubleshooting ideas for a Kubota tractor PTO not fully engaging. However, your PTO is likely all mechanical and has two handles. A lever is used for the clutch plate. The other is for the PTO shifter.

You’ll notice the driveshaft runs from the engine’s clutch all the way to the agricultural gearbox at the rear of the tractor. This reduces the RPM to PTO speed and includes a shifter that engages and disengages the PTO. Some models have a two-speed, and some have a single-speed with neutral.

To check for yourself, check the handle of the clutch. This link can bend and will definitely prevent the clutch from engaging. Next, look at the connecting rods for the rear gearbox. Make sure it’s not broken or bent. You’ll see a shaft going through the box located in the upper left corner, and from the back, the shaft moves the gear lever inside. You may want to try disconnecting the outer rod and using a vise to exercise the lever.

Finally, try turning the PTO shaft manually. When moving one way, it should be free and very easy to turn. When reversing the other direction, it should be connected to the PTO drive shaft, clutch, and steering more difficult.

3. What if the PTO is ground but not bonded?

Kubota tractor power output problem
For most PTOs, there is no external adjustment. It’s all internal, and it consists of a clutch pack that can of course be replaced. You should be aware that the damage to the clutch pack is due to overloading the PTO’s task. For example, asking a 50-hp tractor to do the job of a 65-hp grinder/mixer will quickly cause problems with the clutch pack.

Often PTO clutch rings and shafts need to be replaced because people use tractors to run 4-5 feet of garden tillers and bush hogs without a slip clutch.

PTO Shaft for Agricultural Gearbox

Agricultural equipment includes a variety of PTO shafts. Each one is connected by yokes at each end and rotates between 540 and 1,000 rpm. A safety shield is commonly installed on both ends of a PTO shaft to protect the operator. These protective shields are also found in tractors and agricultural implements, ensuring maximum efficiency. The use of internal yokes also provides added safety.

The agricultural PTO gearbox is designed to change the output speed of a PTO shaft. It can be used as a decreasing or increasing ratio gearbox. With the decrease ratio gearbox, it reduces the PTO shaft’s speed from 1000 rpm to 540 rpm, allowing you to use equipment designed for 540 rpm. On the other hand, an increasing ratio gearbox increases the speed of the PTO shaft from 540 rpm to 1000 rpm.
