20 hp 42 in. Deck Lawn Tractor – CA Model

I have a Bolens 38″ twin blade mower. The engine will start fine, but I can’t get the mower to go forward or reverse. I can move the lever into F, N and R but the clutch will not engage. I looked underneath to see if the clutch spring was attached and everything looks fine. Any ideas?

How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

If the PTO clutch is not receiving power, the clutch solenoid is defective, or the clutch itself is worn out, the blades will not engage. Since a PTO clutch is not repairable, you will need to replace a broken or worn out clutch with a new one.
Belt-the number one cause for your blades not to engage is that your belt is either stretched or loose causing it to slip or fall off completely. Belt could have snapped also. When you are trying to process too much grass/leaves they could pack up under your deck and push off your belt.
Check the fuse

The fuse on most riding mowers is connected to the small red wire that connects to the starter solenoid post. Check the fuse and replace it if it`s blown. If you replace the fuse and it continues to blow, you`ll need to find the short in the wiring or component that`s causing the fuse to blow.

If the PTO clutch is not getting power, if the clutch solenoid is defective, or if the clutch is worn out, the lawn mower blades will not engage. The PTO clutch is not repairable—if the clutch is defective, you must replace it.
If you hear strange noises coming from your mower deck, it may be a sign that the spindle is damaged. A bad spindle can produce grinding, rattling, or squeaking sounds, which indicate that the bearings are worn out or the spindle is bent.
The possible causes of a lawn mower blade spinning but not cutting grass include a damaged or wrongly installed blade, a dull blade, or damaged lawnmower tires. Other possible reasons can be improper tire pressure, a clogged deck, or a broken mower belt.
Loose, Dirty or Disconnected Spark Plug in Your Lawn Mower: Check it out, clean off debris, re-connect and tighten. Dirty Air Filter: Clean or replace. Fuel Not Reaching the Engine: Tap the side of the carburetor to help the flow of gas. If this doesn`t work, you might need a new fuel filter.
What to Do If Your Tractor Won`t Start, Just Clicks. If your John Deere won`t crank and all you hear are clicking sounds when you turn the key, you likely have a bad battery or a bad connection somewhere between the battery and the starter. Double check that the alternator and battery connections are clean and tight.
To achieve this, many modern manual vehicles use a clutch switch (or clutch sensor) which is a small component located under the dashboard near the clutch pedal. Its job is to prevent the car from starting unless the clutch pedal is pressed down, disengaging the transmission form the engine.
Power take-off (PTO) clutches provide a mechanical disconnect between the power created by gas and diesel engines or electric motors to another piece of equipment. The PTO clutches enable the transmission of that energy to auxiliary equipment that does not generate its own power.
Signs Your Spindle Is Damaged

Looseness: A bad spindle can cause the wheel to feel loose when driving due to the spindle being bent or out of alignment. It can be a serious safety issue because it can affect the vehicle`s handling. If you notice that your wheel feels loose, have your vehicle inspected immediately.

If your clutch won`t engage, It usually means that the engine idle speed is different to the clutch idle speed. This can result in damage. To correct this, change the spring or change the engine speed to below the clutch idle speed. If damage is excessive it will require the repair or replacement of the clutch.
The clutch is operated by pushing on the clutch pedal inside the vehicle, which causes the clutch to disengage, and as the pedal is released the clutch will engage. Depending on the type of system the vehicle has, it will either have a hydraulic operated clutch or cable operated clutch.
To fix a riding mower that won`t move forward or reverse, you should fix the battery, check for the air filter and carburetor, inspect the transmission for damages, replace the damaged drive belt, and inspect the spark plug. You must also replace the tires, and adjust the wheel position.

Blades wont engage have 12 volts to the clutch when switch is pulled.
