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 :

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.
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.
A badly worn or stretched belt can slip, causing the blades to turn very slowly or not at all. This is relatively common, as belts tend to stretch over time and need to be replaced regularly. A seized shaft on a spindle can cause the pulley not to rotate, and this can cause the belt to snap.
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.
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.
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.
Burned or Glazed Side Wall: As the mower belt continues to get used, the belt will wear down. As a mower belt wears down, the side wall of the belt will begin to look burned or glazed. This is another sign that your belt is worn and needs to be replaced.
Your Mower Won`t Start:

Other possible causes include: 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.

There may be old or bad fuel in the carburetor float bowl. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and make the engine hard to start. If the carburetor is clogged, try cleaning it with carburetor cleaner.
On a Putzmeister MR 688 series the PTO Pump/Drive switch gets its power from a fuse located in the Mack fuse block.
Most lawn mower blades rotate in a clockwise direction (counter-clockwise when viewed from below), and as such have the cutting edge on the right side. If you are unsure of how your mower rotates, check the position of the discharge chute; if it is on the right side angled back, the blade turns clockwise.
Place the blade bolt into the centre hole and then tighten it to a torque of 30-35Ft/Lb or 45–55Ft/Lb, depending on your mower type. It is important to check bolt specifications for your individual mower`s torque settings to ensure it is not over or under torqued.
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.
Generally speaking, the blade should be tight enough so that it doesn`t move around on its own, but you should be able to move with your hand by applying some pressure. The manufacturer should provide a proper tightening level expressed in foot-pounds, commonly found in the mower`s manual.
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.

Power to turn the blades is intermitent. What should I look for?
ANSWER : Loose connection, corrosion on connections. If this machine is new to you, do you have to have the brake or clutch on to activate the blades? I would lean towards wires/connections as the cause of your intermittent problem.

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.
ANSWER : 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

Good luck!!!

I have a 20 hp z force 44 and the mower blades wont come on . I have changed the pto switch and the safety switch under the seat. I have also checked the fuse and its good. what else is there?
ANSWER : Hi, check you have voltage at the pto plug in connector when the mower is running and the pto switch on. If so the pto needs replacing. If not you have a bad contact or broken wire somewhere. Hope this helps, regards Phil.
