How to Identify and Fix Common Gardening Problems ?

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.
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.
If the engine dies when the blades engage, it could be the result of a damaged safety switch. The first step in assessing the safety switch is to make sure it is plugged in securely. The switch is located underneath the seat, and you may have to remove the seat to reach it.
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.
Find the plunger at the top of the attachment lift lever. Press the plunger inward with your thumb, and move the attachment lift lever back, or toward you, to lower the cutting blade. Release the plunger and attachment lift lever. Pull the attachment clutch switch outward to “Engage” to make the cutting blade rotate.
If your mower blades will not turn after the blade controls have been engaged, your deck belt may be broken. The deck is located directly under the operators seat. This belt spins the mowers blades and runs through a pulley system of idlers. The exact configuration of the deck belt will depend on your model of mower.
Details. Where are the safety interlock switches located on a riding mower? There are 4 safety interlock switches on our lawn and garden tractors.
You Lose Power in the Middle of Mowing:
Here`s why this happens and what you can do: Dirty Air Filter on Your Lawn Mower: Clean or replace. Dirty Spark Plug: Clean or replace. Build Up of Clippings & Debris: Clean underside of your lawn mower deck as noted above.
Powershift PTO engagement problems could be from blocked hoses or fittings, bad connections or ground or the solenoid. Mechanical PTO engagement problems could originate from low air pressure, improper cable installation or back lash too tight.
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.
The engine powers both the wheels and the blade, just like a walk-behind self-propelled mower. But instead of being directly connected to it by an axle, the blade on most riding mowers is powered by a belt connected to the engine.

Replaceing mower deck belt on 20 hp 42 mower model no 917275660. Got the belt on. How do I get the cluch spring back on.
Are you refering to the spring attached to the end of the cable that runs up to the lever on the dash to engage the blades? All you needed to disconnect was that cable on top of the idler arm that’s held in place by a ‘hairpin’ and the left pulley cover to put the belt on.

Have you checked the bearings?
I started the mower but the blades will not turn. I shut it off and was able to manually turn the blades by hand. I also was able to turn the belt wheel under the engine and have it turn the blades. With it running and me on the seat, they don’t turn. With it running; brake engaged; and I pull the mower switch to engage them, the mower wants to die. Two questions: Is there a swtich on the seat to insure the blades can not turn while no one is on the seat? Is there a key between the belt wheel and the PTO shaft that needs to be replaced? Thank you.
Most all riders have a safety seat switch now and they do malfuction alot. They are under the seat and are ez to replace most of the time. First look for a wire that is grounding due to rubbing a sharp object. That can be fixed with black tape
