What to Do: Grasshopper Mower PTO Won’t Engage?

A not engaging PTO is undoubtedly a noteworthy problem for the mower. But, without proper info of it, you can not move ahead to troubleshoot it.

For that reason, the reasons and proper fixes of the Grasshopper mower PTO won’t engage are described here.

So, don’t forget to take a glance at them.

Reason 1: Less Delivery of Power

One of the most common reasons the PTO is not receiving a sufficient amount of power.

It can be caused by the battery that can have loose connection with the PTO unit. As a result, the voltage needed to function the PTO is not being delivered.

Solution: Check the Connections and Fix Them

In this case, checking the connections of the PTO unit and the battery can let you reach the root cause. For the loose connections, you can fix them by tightening the wires. After that, charge the battery and check for continuity.

Reason 2: Fuse is Blown

The fuse which is a connection between the PTO and the electric unit can be blown.

When any wire of the PTO unit becomes damaged, it can let the short circuit reach the fuse. As the fuse is already bad, the PTO won’t be engaged.

Solution: Get a New and Compatible Fuse

First, take a look at the fuse and search for blown signs. In case it is not working at all, get a new and compatible fuse for your Grasshopper mower.

Reason 3: Less Transmission Oil

A notable cause is the Grasshopper mower is running with less transmission oil.

A proper amount of transmission oil is required to help the PTO to work. But, when the transmission oil level decreases to a lowest range, the PTO fails to engage.

Solution: Refill New Transmission Oil

To get the PTO back on duty, refill the Grasshopper mower with new transmission oil. But, don’t overfill as the leakage of oil can bring more troubles.

Reason 4: PTO Switch is Bad

A bad PTO switch is the most effective reason behind the PTO not engaging.

Because when the PTO switch is defective, it doesn’t have any continuity. As a result, though you turn the switch on, it fails to send the command to the PTO.

Solution: Check and Replace the PTO Switch

Using a multimeter, you can check the continuity of the PTO switch. Without inspecting, don’t make any move. If you notice it as bad, replace the PTO switch without delay.

Reason 5: Defective Clutch Pack

A defective clutch pack is a barrier for the PTO to get engaged.

In most cases, when you put extra pressure on the PTO, the clutch pack fails to bear that. Consequently, it gets defective over time and causes the PTO to stay disengaged.

Solution: Inspect and Change the Clutch Pack

First, get an inspection of the clutch pack done and see where the issue is. In case the clutch pack is already in an unrepeatable state, learn how to replace PTO clutch on Grasshopper mower.

Why is My Grasshopper Mower PTO Clutch Not Engaging?

Answer: In a Grasshopper mower, the PTO clutch rejects engaging when the clutch solenoid gets no power. In case it is worn out or has got any damages, the engagement may not complete. An old PTO clutch solenoid seems to have this problem frequently.

What Causes a Grasshopper Mower PTO to Stop Working?

Answer: A Grasshopper mower PTO stops working as soon as the air pressure gets lowered and it doesn’t increase. Because the air pressure has a significant role in helping the PTO to function. However, the overtightened backlash can affect the job of the PTO.

Final Thoughts

In the end, a fact is clear that simple mistakes of the rider can cause the PTO issue. From now on, Whenever your Grasshopper mower PTO won’t engage, make sure to check the listed possibilities.

As for applying the fixes, first be sure of the accurate cause. However, if your Grasshopper mower blades won’t engage and they are bad, learn how to change blades on Grasshopper mower.
