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 :

Blue or white smoke coming from your engine usually indicates burning oil, which can be caused by: Overfilling the crankcase with oil. Incorrect oil grades. Operating engine at greater than a 15 degree angle.
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.

If you have a riding mower like a lawn tractor and there is white smoke, this is usually an indication of excessive oil being added to the reservoir, or you may have a fault with the carburetor. It could also be a sign of a blown head gasket, but that is more rare.
White or blue smoke may indicate an oil spill on the engine.

The smoke may look disconcerting, but it`s completely harmless. Solve the problem by restarting the mower and allowing the spilled oil to burn off.

White Smoke

In extreme cases, you will need to replace your head gasket. At the first sign of white smoke you can try head gasket repair treatment to seal the leak before you do serious damage to your engine.

White smoke from your exhaust almost always indicates a blown head gasket, and just like there is coolant mixed with your engine oil, there will also be engine oil mixed with your coolant.
If your smoke problems persist, chances are the oil seals in the engine lubrication system or around the pistons are the issue, or you may even have a cracked crankcase. These are repair jobs for a small engine pro, unless you`ve got experience working on engines.
A sputtering engine is a sign of a lean fuel mixture in the combustion chamber. This can happen if you have a clogged somewhere in the fuel system that impedes the delivery of fuel into the chamber. For example, your fuel filter or fuel lines might be clogged.
If your car sputters when you step on the gas, it`s crying for help. A sputtering car might mean you`re about to run out of gas, or it could point to something more serious like an issue in the fuel or exhaust system, including dirty or worn-out parts.
White smoke coming out of your exhaust suggests that coolant or water has inadvertently entered the combustion chamber. When it`s burned within the block, it produces thick white smoke that exits through the exhaust.
If you`ve noticed your lawn mower smoking and leaking oil, it`s most likely due to a dirty air filter. The air filter in an engine keeps debris and dirt out of it, while the grass and dust accumulate over time. When the air filters are clogged, oil can leak into the engine and out of the exhaust system.

Have a toro recycler white smoke continuous after starting
ANSWER : This is not a good sign!! You have blown a head gasket, the rings around the piston have gone bad, or you have blown a hole in the piston.The head gasket isn’t so serious, and it may be worth fixing. However, the other two scenarios are serious and wouldn’t be worth fixing if the mower is old.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.

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.

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
