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.
The most likely cause of a no-start mower after running out of gas is dirt in the carburetor, but other possible causes include: Air locked gas system. Faulty carburetor. Contaminated gas.
The blades and/or spindles could be worn or out of balance. There may be bent, damaged, or disconnected deck hangers that would require service.
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.
If your lawnmower is starting and then stalling, the most likely issue is the carburetor. The most common issue is that the carburetor is dirty. Here`s what you need to know about how a dirty carburetor can cause a lawnmower to start, then stall out and die.
If the engine will not crank, you likely have a problem with… Discharged / defective battery or faulty electrical connections. To address these issues, check the battery and charging system for problems. Faulty parts: potentially the safety interlocks, starter motor switch (open circuit) or solenoid.
A small pipe called a venturi runs alongside the gas nozzle. When the end of the venturi pipe becomes submerged with the rising gas, it chokes off the air pressure that holds the nozzle handle open and shuts down the gas flow.
There is a reason gas pumps have an annoying habit of shutting off. Gas pump nozzles are designed with a device on the end that turn off the fuel flow when the gasoline runs back into it. This is a safety mechanism which prevents the gas from coming out and spilling when filling up the tank.
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.
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.
As the fuel level drops, a vacuum begins to form in the fuel tank because air can get in to fill the space the consumed fuel occupied. After about 10 or 15 minutes, the vacuum will become strong enough that fuel will stop flowing to the carburetor and the lawnmower will die.
Use Carburetor Cleaner

Fortunately, you can generally do this without even taking the carburetor out of the engine. Start by purchasing some commercial lawnmower carburetor cleanerOpens a new window, which comes in a simple spray can and will make it easy to clean the inside and outside of the carb.

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.
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.
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.

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. Check the crankshaft connection to see if it rotates freely. Inspect the connecting hardware for damage or rust.

This is a cub cadet zero turn 2007 model

The problem: electronics will not engage.

The unit was mowing and running when I moved to another location and started the mower it started fine.

Unloaded and went to engage the blades but they would not engage. Got off the machine to check things out belts etc. were OK got back on the machine and it wouldn’t start even the hour meter failed to light up.

Battery is fully charged, I can take a screw driver and “jump” the leads at the seleniod and get the engine to turn over, but not start.

I just need to know where to start looking for the problem. I though about hard wiring the safety switches starting with the seat.

On my cu cadet zero turn only the left side turns and the right side moans but wont move ever with the release lever to free wheel released
ANSWER : Check the hydraulic oil level for the hydrostat drives(if it has a reserve tank located under the seat. Some ZT’s don’t have the reserve tank. Don’t over fill that tank. 1/4 inch above the bottom is all it needs.)

Also, check the steering arm bolts. Very often they work themselves loose and the arm doesn’t pull the valve rod that controls the hydrostat unit.

I have a cub cadet 2165 I just put in a new battery and it is slow turning over any ideas?
ANSWER : If battery is good and everything is hooked up right. Most likely could be the pto clutch bearing. Not the bearing on the pulley but on the clutch inside. Had the same problem, took the spark plugs out got it free. Turned over easy with plugs out, Started right up after and then burned up my bearing. Don’t burn up bearing. If do field assy. For that is 200$ if you can get away with just that. Otherwise 350-400$ for full assy.
