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 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.
An improperly routed belt can cause the engine to die when the blades are engaged. To check belt routing, lower the deck to its lowest setting and remove the belt guard by the drive pulley. Next, lift the belt over the pulley and remove the pins that support the deck at the rear.
If the mower vibrates when you engage the cutting blades, there might be a problem with the blade drive system. Deck vibration can be caused by an unbalanced blade, worn pulley or mandrel, bad blade belt or debris caught inside a pulley. Loose nuts or bolts on the pulleys, mandrels or blades can also cause vibration.
A broken shear pin is the most common reason the snowblower auger won`t turn properly so replace any broken shear pins. Worn or loose belts also prevent the snowblower auger from spinning. Check and adjust the belts and replace any broken or worn belts when you see the snowblower auger not turning.
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/when the PTO exceeds the preselected RPM setting, the EOC will de-energize the solenoid valve, disengaging the PTO.
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.
Mower blades are spinning 4000 RPMs. An unbalanced blade spinning that fast will cause a significant amount of vibration, which will put stress on yout blade shaft, spindle, and even the engine.
While there are several reasons this might happen, it is most commonly the result of an uneven deck or misaligned blades. Make sure the blades are facing the correct direction and are not warped. Check the mower spindle and repair it if necessary. Check if the deck is level and if not repair or replace it.
Worn bearings about to fail completely often make grinding noises, as well as unusual vibrations. The mandrels holding the mower deck`s cutting blades contain two bearings that need frequent lubrication to keep the bearings working properly. As bearings dry and overheat, seals fail and dirt enters the mechanism.

Do I need a new engagement motor?

Arien 34- Blades won't engage – Ariens 34 In. Zoom Series Riding Mower
ANSWER : This mower has an electric PTO on it. I had a Scag and the electric PTO clutch went out on it. Not the cheapest things to change but easy to do yourself with some basic tools. Also, before running out and getting a new one, check the wires to it and to the engage/disengage switch. You may have a bad connection.

Mower dies when the blade is engaged kawasaki 48″ cut walk behind.
ANSWER : Well first you should check to make sure that the blades move freely. While the engine is off you can (safely, with a glove) grab one off the blades and see if you can move it freely,(the other two should move as well) By process off elimination you should be able to figure out which blade is giving you trouble. I’m guessing it could be as simple as something wrapped around the blades, to as complex as a bearing has gone bad. If this doesn’t take care of your problem you can reply back, being more specific and I’ll do what I can to walk you through this. Please rate my answer.
