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 fault could be a dirty spark plug, air filter or carburetor, or it could be related to the quality of the gasoline used. Slow starting can also be the result of a failure to clean the blades. In most cases, you should be able to restore performance yourself.
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.
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.

If the engine starts, but does not run smoothly, it means that the spark plug and ignition system are in order and you need to look elsewhere for the source of the problem. The usual culprit is air intake or fuel system related.
The engine pulley

One pulley is connected to the engine while the other is located behind the lawn mower. The engine pulley on the other hand is located on the engine`s crankshaft. Increase the size of both pulleys will significantly increase the speed of your lawn mower.

The governor system is like a cruise control system. It maintains the speed of your lawn mower or outdoor power products.
The most likely reason a mower is hard to push is that the drive cable needs adjustment. Other possible causes include: Worn drive belt. Damaged pulley.
If your lawn mower starts, runs for a while, then dies, check the ignition coil, gas cap, and spark plug. One or more of these parts could be causing your problem. Follow our repair and symptom guide to help you fix this.
If your lawn mower starts, runs briefly, then dies these are the four most common reasons that`s happening: Dirty carburetor / clogged carburetor bowl. Old gasoline that has gone bad. Dirty or defective spark plugs.
Use carburetor cleaner to remove deposits, clogs & debris

Luckily, you can take care of many of these problems quickly and easily; often without even removing the carburetor from the engine.

Poor combustion makes your RPMs high and makes you slow down on acceleration. Bad spark plugs lower the car`s mileage too. Hence, immediately replace your car`s faulty plugs.
But we conduct our mowing tests at about 3.5 mph, the optimal speed for achieving the most even cut. (Depending on grass density and height, you might need to go even slower.) Mow at twice that speed and you`ll finish more quickly, but we don`t think you`ll be satisfied with the results.
The type of lawnmower: The average, common lawn mower speed is 3 mph for a push mower, 3–5 mph for a lawn tractor, and 7–13 mph for a commercial stand-on mower. Your speed in mowing: Some clients may not consider this factor so much, but it is important for them to consider it.
A dull blade can make your lawn appear yellow, brown and raggedy. A dull lawnmower blade may even pull up portions of the grass because it actually pulls on the entire plant instead of slicing through the blades of grass cleanly.
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.
Dirty air filters are one of the most common reasons lawn mowers sputter. Dirt can be present in the apertures that lead from the carburetor and the fuel filter and interrupt the flow of fuel supply to the combustion chamber. You want to be sure to clean or replace dirty air filters.

A dirty air filter is one of the most common causes of a poorly running lawn mower, since it starves the engine of the oxygen needed for combustion. Fuel Filter: Check the fuel filter on the mower to make sure it`s clean, and replace it if needed.

I have had a poulan pro 550 series push mower for almost 1 year at the end of the season last year the mower would start briefly and then stop. i have cleaned out the air filter and that did not help.the mower started, i made one revolution around the yard 3/4th of the way the mower quit. I then primed the mower it started then quit and now it will not start at all. Does anyone have any suggestions of what to do. Thanks
ANSWER : There is a little spring that works the carburetor arm. If that popped off then the mower will not run.

Mower runs at slow speed only
ANSWER : Sounds like you will need to clean your carburetor.
Sometimes you can get by with priming it a few times, and letting it run a few times like that and it will flush the gunk out of the jets,but most of the time you will need to rebuild the carburetor.If the mower is over a couple years old, then I also recommend that youbuy and install a new carburetor repair kit, because the diaphragm willget hard and that will cause it to be hard to crank.When you clean your carburetor and remove the jet screws, count the number of turns it takes to seat the jets from their original position.That way when you go to put the jets back in, you know how many turnsthey were in/out.Please rate me, ThanksGood Luck, I hope this helped

I have a Poulan push mower that after mowing in a ditch started making a loud noise and running rough. It almost sounded as if metal was hitting metal. The mower was vibrating more than normal. I checked under the mower and nothing is hitting. After a few times of stopping the mower engine because it sound as if it is going to die down the mower will not start now. The shaft does not appear bent and the blade appears ok. The mower has oil, a good spark plug and a clean air filter. It was running fine until that moment. I did not see anything that I hit but it is possible I hit something in the ditch like a pine cone or branch. What could the problem be and how would I go about fixing it?
ANSWER : If you are sure the oil level is correct then it sounds like it’s about to die, unfortunately. A pine cone shouldn’t cause any damage, but a large branch may do so. Was it smoking before you shut it down? The vibration could be caused from a bent blade. It could also be caused from a part breaking in the motor. I wish I could have given you better news!

Good Luck,

Jim

Lawn mower cranck but wont start…
ANSWER : Since you already checked for spark and air I would drain all the fuel out of it and check that fuel for water. Over time some lawn mowers end up with contaminated fuel. You can see the water sitting on the bottom of the fuel if you let it stand for a bit in a small plastic bowl.

Be sure to empty and dry out you fuel can as well. Especially if the mower stopped running right after a refuel. Which is a good sign your gas can is contaminated too.
