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 :
Other things that could cause this issue are bad fuel, weak/colapsed/kinked fuel line, faulty spark plug, faulty ignition/coil, oil over full, clogged air filter, plugged/dirty carburetor, worn engine parts internal rings/valves/etc.
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 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.
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.
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.
Your lawnmower may stop running when hot due to an overheated engine, air leaks, a clogged fuel system, or the carburetor not getting enough gas. It is also possible that the engine is not cooling as it runs because of a dirty air filter. Finally, worn-out pistons may also be the problem.
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.
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.
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.
The most likely culprit is a dirty or clogged air filter. Issues with your fuel pump or fuel filter can also cause your engine to idle then die with any throttle. If you have an older car, it could also be a bad carburetor.
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.
If a mower is hard to start, it may be the result of a dirty carburetor and/or a clogged air filter. Use a screwdriver to remove the carburetor and clean any dirt out of it with a rag. Clean the air filter or replace it if it`s disposable.
The carburetor might be clogged. A clogged carburetor is most commonly caused by leaving fuel in the engine 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.
Problems arise in cold weather, because cold air is oxygen-rich, as you can imagine throws the ratio way off. Without the choke, the engine gets too much air for the amount of gas the engine receives. We call this a lean condition. A mower just won`t start or starts and stalls right away when the AFR is too lean.
Before mowing a lawn after a rain, inspect the grass closely to see if any blades are bent over. Once they are upright it`s probably safe to mow. Wet grass tends to cut less cleanly, resulting in larger clippings. These wet clippings like to clump together and block up the mower`s deck.
An engine that will fire and run with the choke closed but dies when the choke is opened likely has debris at least partially blocking the fuel passages in the carburetor. In this condition the closed choke provides enough extra fuel to enter the engine to overcome the lack of fuel flowing through the other passages.
what temperature is “too hot” to mow grass. When temperatures go beyond 80°F, your cool-season grass may begin to struggle. And when high temperatures last for extended periods of time, it can cause your grass` growth to slow down and its vibrant green color to fade.
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.

Look to the bottom right of the screen to make sure the engine is not starting to overheat. To make the job easier, mow to the highest allowable cut length when the grass is longer. This will reduce stress on the engine and save time when mowing.

I would like to replace the mulching blades on my Sears Craftsman riding mower with regular cutting blades. I can find plenty of sources for new mulching blades, but not cutting blades. My mower is a model 917.259541 tractor and the blades currently on it are part #134149. I want to make sure I get the right size to replace them. Also, is there a source for a bagging system for this mower, that won’t cost as much as one from Sears?
ANSWER : The straight blade for the 42 inch mower is 138971.They cut better and are easier to sharpen and you will need them if you use a gass catcher. If you do not want to use sears for parts you may be able to find good deals on ebay.

Mower cranks and runs smooth until i try to engage blades or put mower in gear. it then stalls out
ANSWER : The seat switch is not making. You can start the mower but if you try to move it or cut, the switch is acting as if there is no operator present. Find it under the seat.
