If your Ferris electric PTO (power take-off) is not working, there could be a problem with the charging/generating system. The engine makes electricity to charge the battery and actuate the electric blade clutch. Problems with the PTO clutch can include slipping, voltage loss, or complete jamming. To fix this, you can replace the clutch with a new one. However, before replacing the clutch, you should verify which part is correct for your particular Ferris unit by entering the model number and selecting the appropriate diagram and part.

What You'll Learn
Identify the issue: PTO clutch slipping, voltage loss, or jam
The PTO clutch, or Power Take-Off clutch, is the main link between the engine and the mower blades, transferring power from the engine to the blades. When the PTO clutch slips, voltage is lost, or the clutch jams, it can cause the blades not to engage. This can be due to several issues, including:
PTO Clutch Slipping
PTO clutch slipping can be caused by abrupt engagement or release of the PTO lever, which can cause misalignments and belt slippages. To avoid this, it is important to engage or release the PTO gradually and to disengage other attachments before operating the PTO lever. Proper maintenance, such as regular oiling and cleaning, can also help prolong the lifespan of the clutch and reduce the likelihood of slipping.
Voltage Loss
Voltage loss can occur if the charging/generating system is not working properly. This system is responsible for generating electricity to charge the battery and actuate the electric blade clutch. A faulty battery can also cause voltage loss, preventing the PTO from functioning properly.
Jamming
Jamming of the PTO clutch can be caused by a variety of factors, including mechanical failures, debris buildup, or corrosion. Regular maintenance and cleaning can help reduce the likelihood of jamming.
Troubleshooting Steps
To identify the specific issue with your Ferris electric PTO, you can perform the following steps:
- Check the battery: Use a multimeter to test the battery voltage and ensure it is functioning properly. If the battery is weak or faulty, replace it.
- Inspect the charging system: Verify that the charging/generating system is functioning correctly. If there is an issue, you may need to repair or replace the system.
- Examine the PTO clutch: Inspect the PTO clutch for any signs of damage, wear, or debris buildup. If the clutch is slipping or jammed, it may need to be replaced. Refer to the Ferris mower parts website for replacement parts and instructions.

Check the battery and charging system
To remove a Ferris electric PTO, it is important to first check the battery and charging system. Begin by inspecting the battery to ensure it is in good condition and holding a charge. A faulty battery may exhibit symptoms such as a rapid drop in voltage or an inability to hold a charge. If you suspect the battery is faulty, consider replacing it with a new one.
Next, verify the proper functioning of the charging system. The engine should generate electricity to charge the battery and activate the electric blade clutch. If the engine fails to start despite a functional battery, there may be an issue with the charging system.
One way to test the charging system is to use a multimeter to measure the voltage and amperage. This will help determine if the system is generating the correct amount of electricity. Additionally, you can observe the behaviour of the electric blade clutch. If the clutch is slipping, experiencing voltage loss, or jamming completely, it indicates a potential issue with the charging system.
In some cases, the charging system may not be the root cause of the problem. For instance, a faulty PTO switch or a weak battery may be responsible for the blades not engaging. It is important to systematically check each component to pinpoint the exact source of the malfunction.
If you are unsure about the condition of your battery, consider investing in a load tester to accurately assess its performance. Alternatively, consult a professional or a repair service to help diagnose and address any issues with your Ferris electric PTO equipment.

Use a jump-starter or load tester
If your Ferris electric PTO (power take-off) is not working, one possible solution is to use a jump-starter or load tester. This method can help determine if the issue is related to a faulty battery. Here's a step-by-step guide on how to approach this:
Use a Jump-Starter:
- Obtain a compact jump-starter that matches the voltage of your Ferris mower, typically 12 volts. Ensure it has sufficient amperage, such as 12V/1000amp, to turn the engine over.
- Connect the jump-starter to the battery terminals, following the manufacturer's instructions for proper polarity.
- Attempt to start the engine with the jump-starter connected. If the engine cranks and runs, it confirms that your mower battery needs replacement.
- Proceed with caution and mow your lawn, but be aware that the PTO may still not engage due to a weak battery.
Use a Load Tester:
- Acquire a load tester, which is a device used to test the condition of a battery.
- Connect the load tester to the battery terminals, ensuring proper polarity.
- Interpret the results: a good battery will show a healthy charge and be able to handle the electrical load. A bad battery will show low voltage or high resistance, indicating it needs replacement.
- If the battery tests bad, replace it and then attempt to engage the PTO.
By using a jump-starter or load tester, you can isolate the issue to the battery and make an informed decision about replacement. However, if the problem persists or other symptoms arise, further troubleshooting or professional assistance may be required to resolve the issue with your Ferris electric PTO.

Replace the PTO clutch belt
To replace the PTO clutch belt on a Ferris mower, you will need to identify the correct replacement part for your specific model. This can be done by referring to the mower's manual or by contacting the manufacturer. Once you have the correct part, follow these steps:
- Park the mower on a flat, level surface and engage the parking brake to secure it in place.
- Disconnect the power supply to the PTO clutch. This will typically involve removing the wire harness connected to the clutch.
- Locate the PTO clutch assembly, which includes the clutch, gearbox pulley, idler pulley, and idler arm.
- Loosen and remove the PTO clutch anchor bolt using the appropriate tools. This will allow you to access the clutch belt.
- Inspect the clutch belt for any signs of wear or damage. Replace the belt if it is damaged or excessively worn.
- Remove the old clutch belt by sliding it off the pulleys and idler arm. Clean any debris or grass clippings from the pulleys and idler arm before installing the new belt.
- Install the new clutch belt by routing it around the pulleys and idler arm in the correct orientation. Ensure the belt is properly aligned and seated in the grooves of the pulleys.
- Tighten the PTO clutch anchor bolt securely, but be careful not to overtighten it as this can damage the threads or put excessive pressure on the clutch components.
- Reattach the wire harness and any other disconnected components. Ensure all connections are secure and properly routed.
- Release the parking brake and start the mower to engage the PTO clutch. Observe the operation of the clutch and ensure it is functioning properly.
By following these steps, you can safely replace the PTO clutch belt on your Ferris mower, ensuring it continues to transfer power efficiently from the engine to the blades. Always refer to the operator's manual for specific instructions related to your mower model and seek assistance from a qualified technician if you are uncomfortable performing any of the tasks.
