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 :

The pulleys in your lawn tractor are driven by the drive belt, and turn the spindles. If a pulley doesn`t spin freely, it can cause the engine to die when the blades are engaged. To check the pulleys for sticking and damage, first remove the drive belt from the engine pulley and lift the lever to engage the blades.
There is a safety switch at the end of the cutter engage lever which has gone faulty and needs replacing, overiding the switch by keeping it pressed in will allow the mower to be operational till replacement switch is fitted.
Whenever the blade is engaged, it rotates on a crankshaft to cut the grass. But if there is interference in this rotation, the engine can overload and shut off or lose power.
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.
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.
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.
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.
A dull blade is the number one reason for leaving uncut grass. The blunt blade will damage your lawn in no time at all; it tears the grass and leaves a jagged edge which turns the grass tips yellow. The recommended way to repair the yellow grass damage – regularly cut with a sharp lawnmower blade.
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.
Replace dirty or clogged fuel filter. Replace old gas with fresh gas (properly dispose of old gas). Check oil level and add if low. Adjust cutting height of mower before cutting tall grass.
Worn or broken blade drive belt – If the riding mower blades are not spinning, the blade drive belt may be worn or broken and unable to engage the blades. If the belt is intact, inspect it to see if it`s loose or slipping on the pulleys then replace it with a new one if necessary.
A good rule of thumb for the average homeowner is to replace your mower blades annually. You may also think about replacing them if they become damaged. Dig up that product manual if you want a more clear-cut answer. Always make sure to take protective measures whenever sharpening your mower blades at home.
Most problems that will cause a John Deere lawn mower to stall after 20 minutes occur due to the distribution and rate of flow in the fuel and air systems. If these systems are dirty or restricted, the mower will stall out and be difficult to restart.

Clogged or Dirty Air Filters

It is one of the most common problems that cause lawnmowers to sputter. The mowers take the air from the surrounding through air filters and mix it with fuel inside the engine. So, if the air filter is clogged or dirty, it will affect the flow of air into the carburetor.

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.
