Why won’t my blades engage on my John Deere?
It is possible that there are a few different things that could be causing your John Deere blades not to engage. First, if your machine has an electric clutch, it is possible that the clutch is not engaging correctly.
Check the wiring harness and connections and make sure everything is securely connected. If the connections are all good, then the clutch could be bad and need to be replaced. Another potential issue could be with the PTO (power take-off) switch or relay.
The switch can potentially become damaged, worn out, or have a wiring issue. Make sure all connections are secure and the switch is not stuck. If the switch is still not functioning correctly, it will need to be replaced.
Another potential issue could be that the drive belt that runs the blades is worn out or loose. Inspect the belt for any signs of wear or looseness, and if needed, replace the belt. Finally, it is possible that the blades just need to be sharpened.
A blade that has become dull or nicked can cause the blades not to engage. Check the blades for any signs of damage or dull spots, and if needed, sharpen or replace the blades.
What is a PTO clutch on a riding mower?
A PTO (Power Take Off) clutch on a riding mower is a device used to transfer power from the lawn mower’s engine to the cutting blades. When engaged, the PTO clutch allows the cutting blades to spin and cut grass or other material.
The PTO clutch is usually engaged by means of a lever or switch located on the dashboard area of the lawn mower. Engaging the PTO clutch requires the engine to be running and is usually done when the operator is ready to begin cutting.
When the PTO clutch is engaged, the lawn mower’s blades begin spinning at a speed that is proportionate to the engine speed. The PTO clutch provides a direct mechanical connection between the lawn mower’s engine and blades, which increases the cutting efficiency.
PTO clutches are available as both electric and hydraulic models. Electric PTO clutches are easier to install, but require the operator to touch the clutch lever in order to engage it. Hydraulic PTO clutches are a quieter option, and may provide more torque in certain situations.
Regardless of the type of PTO clutch used on a riding mower, it is important to inspect and maintain the unit regularly in order to ensure safe and efficient operation. Additionally, only specific types of blades should be used with a given PTO clutch model; using the wrong type of blade could lead to poor performance and/or damage to both the PTO clutch and engine.
How do I turn the blades on my John Deere riding mower?
To turn the blades on your John Deere riding mower, you need to locate the PTO switch, which is usually located on the dashboard of the mower. Once you have located the switch, turn it clockwise, which will activate the PTO power take-off.
This will engage the blades on the mower, allowing you to begin mowing your lawn. It’s important to ensure that the PTO switch is turned off after you are finished mowing. Be sure to disconnect the spark plug wire from the spark plug, and then turn the switch back to the engaged position.
This will ensure that the blades do not become engaged and cause injury or damage to yourself or the mower.
Where are the safety switches on a John Deere riding mower?
The safety switches on a John Deere riding mower can be found in two places. The first is on the handlebars. On some models, there will be a Red button, which needs to be pressed in order to start the mower, or to move the mower from the forward to reverse position.
On other models, you’ll find a yellow lever which needs to be squeezed in order to start the mower.
The second location of the safety switches on a John Deere riding mower can be found under the seat. On some models, there will be a Red button that needs to be pressed in order to start the mower, or to move the mower from the forward to reverse position.
On others, there will be a black handle that must be pulled up in order to start the mower.
It is extremely important to make sure that both safety switches are functioning properly before attempting to use the mower. To do this, you’ll want to inspect the switches, and make sure they are both able to move freely, as well as making sure they both properly activate when pressed or pulled.
How does a PTO switch work?
A PTO (power take-off) switch is an electrical switch used to disable or enable the transmission of power to an auxiliary device such as a winch or dump bed on a vehicle. The switch activates a solenoid mounted on the transmission, which in turn disengages the power being provided by the transmission.
When the switch is used to enable power to the unit, hydraulic pressure pushes the solenoid closed and the power is transmitted. When the switch is used to disable power to the unit, the solenoid is opened and the power is cut off.
The most common causes of failure of a PTO switch are improper installation, corrosion, and age. If a PTO switch is not installed correctly, it can be difficult to operate and may not be reliable. Corrosion of electrical contacts can result in intermittent performance or a complete lack of power delivery to the auxiliary device.
If a PTO switch is more than 10 years old, the contacts may be worn and the unit may not be providing power reliably. It is recommended to replace a PTO switch if it is more than 10 years old to ensure reliable operation.
Which way do mulching blades face?
Mulching blades are designed to be installed with the cutting edge facing downward. The angle of the blade is also important and should be installed so that it is angled to cut the grass cleanly. Installing the blade with the wrong angle or with the cutting edge facing upward can cause scalping, where it will cut down on the blades of grass, leading to an uneven lawn.
Taking the time to properly install the mulching blade with the cutting edge facing downward will ensure you get the most out of your lawnmower and a well-maintained and manicured lawn.
Are John Deere blades reverse threaded?
No, the blades on John Deere mowers are not reverse threaded. They use standard threading that is normal for most lawnmower blades. The threading pattern is right-handed threading, meaning that any rotation of the blade in a clockwise direction is tightening it, and any rotation in a counter-clockwise direction is loosening it.
John Deere blades used to have simulated reverse threads, but these were discontinued with newer mowers. The simulated reverse threads were designed to make it more difficult for people to remove and replace the blade without the proper tools.
Why won’t my riding mower blades engage?
It’s important to narrow down the possible cause first, so you can make a plan for repair.
One potential reason for the blades not engaging could be an issue with the engine. If your riding mower is not getting enough power, the blades will not engage. Check the fuel, air filters, and spark plugs to ensure the engine is receiving the proper power necessary to turn the blades.
If these check out, the next step is to inspect the belt and pulley system that turns the blades. Make sure that the belt is in good condition and is properly connected to the drive pulleys for the blades.
If the belt and pulley system is in good condition, then there may be an issue with the electric clutch that engages the blades. If there is no power reaching the clutch, it will not engage the blades.
Test the electric clutch with a multimeter and make sure power is being provided when the engine is running.
Finally, if all of these steps check out, then you may have a broken blade switch or solenoid. This part is part of the electrical system controlling the blades and sends power to the blades when the switch is engaged.
If the switch or solenoid is broken, it is advised to replace the parts to ensure proper operation.
Why will my Husqvarna not move?
These could be related to your drive belt, tires, or fuel system.

Additionally, the pull cord may not be working, or the starter solenoid may be faulty. It is best to check all of these components before troubleshooting further. If all else fails, it is best to take your mower to a service center so that an experienced technician can diagnose and repair the problem.
Why is my mower deck not engage?
There could be a few potential causes for the mower deck not engaging. It could be due to the pulley not being aligned properly, the belt not having proper tension, the pulleys being worn out or a failed clutch, or a failed transmission component.
It is important to check the pulleys and tension, as well as the belt for signs of wear or damage. If you’re comfortable enough, you can test all these components by manually engaging and disengaging the mower deck from the tractor.
If any of these are damaged, they will need to be replaced. It’s also possible that the transmission is not engaging properly, in which case the entire transmission would likely need to be replaced. If you find that the clutch is to blame, it is likely the result of a worn out bearing or a damaged component within the tractor’s drivetrain that needs to be repaired.
In any case, it would be a good idea to consult with a professional mechanic or mechanic repair shop to make sure that you correctly identify the issue and correctly repair it.
Can a PTO clutch be repaired?
Yes, a PTO clutch can be repaired. Depending on the type and severity of the damage, it may involve replacing individual components or the entire unit. If it is a minor problem, such as bearing wear or worn electrical parts, then the components can be replaced to restore the PTO clutch to proper working order.
In more severe cases, such as if components have been damaged by water, wear, or other elements, it may be more cost-effective to replace the entire clutch. Additionally, due to the complexity of the PTO clutch, it is generally recommended that the repair or replacement be performed by a qualified technician or mechanic.
How do I know if my mower PTO is bad?
If you suspect that your mower’s Power Take-Off (PTO) is bad, there are a few steps you can take to check. First, turn off the mower and ensure that all parts are at a complete stop. Make sure to remove the key and disconnect the spark plug to ensure that the mower is completely shut off.
Then you can check the PTO clutch itself. Depress the clutch lever, and inspect the mechanism. You should see a confirmed engage when this lever is pressed. If there is no motion or engagement when depressing the lever, the clutch may need to be replaced.
You should also check the PTO cable for any signs of wear or damage. There should be no kinks, broken strands or frayed edges on the cable. If these are present, the cable may need to be replaced. You should also examine the shaft that runs from the clutch to the PTO pulley.
This should turn freely, so if it does not, it could be another sign of needing a replacement.
Finally, start up the mower and try engaging the PTO. If the lever acts as expected and the PTO pulley moves, the clutch is likely in working order. If you experience unexpected movements or the lever is not properly functioning, you may need to replace the PTO clutch.
