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 :

A clogged carburetor is most commonly caused by leaving fuel in the lawn mower for a long period of time. 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 cause the engine to stall.
Check that all the safety switches are working correctly, it is possible the seat switch is bad or loose plug/ bad wire. Also if battery weak or charging system weak/faulty the clutch will stall out engine, charge battery up with charger and try.
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.
A Dirty Carburetor Can Cause a Lawnmower To Start Then Die

By far, the most common issue that causes a stalled motor is a dirty carburetor. The carburetor on your engine is the thing that draws in air and mixes it with the fuel. Contrary to what the movies might make you think, gasoline itself is not very flammable.

Being Overworked

One of the most common reasons that a lawn mower might stall while it is cutting grass is that it is being overworked. This is a mechanism that is intentionally incorporated into the mower to prevent the motor from being blown.

On a Putzmeister MR 688 series the PTO Pump/Drive switch gets its power from a fuse located in the Mack fuse block.
To bypass a safety switch on a lawn mower, you will need to disable either the PTO or seat safety switch. Disabling the PTO switch requires cutting the wires near the engine. You must disconnect and cut wires under the mower`s seat to disable a seat switch.
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.
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. So if you want to get the most life out of your mower… keep the blades balanced! If playback doesn`t begin shortly, try restarting your device.
A full gas tank and oil reservoir are the essential first steps when checking why the lawn mower won`t stay running, but the problem could also be a dirty filter, clogged carburetor, improper fuel mixture, or a dirty spark plug.
Condensation inside the gas tank is one culprit, but moisture can also enter the system through a loose or ill fitting gas cap. The best solution is to drain the mower`s gas tank and refill it with fresh gasoline. A clogged fuel filter can also cause a mower engine to die.
The most common cause of a mower that runs for thirty minutes and then dies is a faulty armature. A faulty gas cap is the second most likely cause.
A dirty carburetor is the most common cause of a lawn mower that starts and then dies. Other possible causes include: Stale/Dirty Gas. Faulty Choke.
Your lawn mower runs for 30 minutes then dies if you are having issues such as a bad spark plug, air problems, a malfunctioning carburetor, or a faulty gas cap. You may even encounter the issue that your lawn mower runs for 5 minutes then dies.
For power shift operation, when a power shift PTO is engaged, a solenoid is energized. Air or hydraulic fluid then compresses a clutch pack in the PTO. This locks the PTO output gear to the output shaft and allows work to be done. When the power shift PTO is disengaged, the solenoid de-energizes.
This operation is crucial to the overall functioning of riding mowers, and thus PTO clutch repair may need to be immediately performed on riding mower models that have a failed clutch. Fortunately, you can fix your clutch irrespective of your experience with PTO clutch installation.
The power take-off shaft on a tractor transmits power from the tractor`s engine to PTO-driven machines or implements. The machine`s drive shaft is connected to the tractor`s PTO stub shaft and transfers energy from the tractor to the machinery.
The PTO is engaged and disengaged using the main transmission clutch and a remote control mechanism which operates on the PTO itself. Typically, an air valve is used to engage the PTO, but a mechanical linkage, electric or hydraulic mechanism are also options.
If full PTO hp is required, the tractor should be run in standard 540 modes. A live PTO, normally, has a 2 stage clutch. You can depress the clutch 1/2 way in and the transmission will stop but the PTO will continue to spin under a load (not just free spin).
An overrunning PTO clutch is a device that allows a tractor`s power take-off (PTO) shaft to be driven in one direction, but to spin freely (freewheel) in the other direction. The ratchet mechanism in an overrunning clutch is similar to the freewheel hub on a bicycle.
The tractor`s stub shaft, often called the PTO, transfers power from the tractor to the PTO-driven machine or implement. Power transfer is accomplished by connecting a drive shaft from the machinery to the tractor`s PTO stub shaft.
Trip switches are basically fuses; when too much current (AKA load) passes through a given circuit the switch (which are rated e.g. 13 AMP) is `tripped` and the circuit is broken.
Overloaded circuits, short circuits and ground faults are all legitimate reasons why your fuses blow on a regular basis or causes for your fuse box to trip out. Other causes could be a result or ageing or faulty wiring as well as power surges.

When cutting with pto on and going into reverse and forward again the pto cuts off
