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 most common cause of excessive vibration is an unbalanced blade. If you`ve recently had your blade sharpened, it`s possible the blade hasn`t been properly balanced during the sharpening process. To fix this, the blade should be removed, rebalanced and refitted.
If you suspect your mower is vibrating excessively due to an issue with the blade, inspect the blade for damaged and test for balance. If it is damaged, replace it. If it is out of balance sharpen the blade so it is balanced or replace it.
When your mower vibrates severely, start by checking whether the blade is damaged, imbalanced or loose. Tighten the blade bolt if it`s loose. Replace the blade if it`s damaged. A rough-running engine can also cause severe vibrations so tune up the mower to cure engine vibrations.
An easy method to reduce vibration is to install a clean damper on the rear shaft of the motor. Clean dampers are basically hermetically sealed plastic cases with an inertia body packed with silicon gel. The extra inertia and silicon gel help absorb the vibration and provides a stable damping effect.
Gas-powered lawn mowers are loud, especially in urban areas where the sound bounces off the structures. Electric mowers do not have the loud noises, or the vibrations mowers typically need to deal with when using gas.
The most prevalent cause of vibration is problems with your wheels or tires. The potential problems include improper wheel and tire balance, uneven tire wear, separated tire tread, out of round tires, damaged wheels and even loose lug nuts.
Worn or dirty spark plugs can cause a petrol car`s engine to misfire in one or more cylinders, which can cause vibrations when the car is idling or at running speeds. The easiest solution is to replace your spark plugs and check the related wiring. Engine vibrations can also be due to the air and fuel systems.
Installing new spark plugs is the best way to resolve such vibration related issues. The timing belt ensures the accurate functioning of many critical components of the engine. Any issues with the timing belt can cause your car`s engine to vibrate.
Vibration-induced white finger (VWF) is the most common condition among the operators of hand-held vibrating tools. The symptoms of VWF are aggravated when the hands are exposed to cold. Vibration can cause changes in tendons, muscles, bones and joints, and can affect the nervous system.
Music and lyrics. McKinnon states that the album`s title, Bad Vibrations, is derived from feelings of stress and anxiety.
As per ISO standards 10,816, the vibration velocity of the induction motor must be within 5 mm/s. In the induction motor under test, it is observed that the vibration velocity is 15.3 mm/s using numerical analysis which violates the ISO standards.
An acceptable vibration level would be below 0.16 in/sec (pk) or 2.8 mm/sec (rms). Restricted Operation – the same motor/pump operating a vibration levels between 0.16-0.25 in/sec (pk) or 2.8-4.5 mm/sec (rms) should be considered to have a problem causing excessive vibration, such as unbalance or misalignment.
In terms of engine life, a gas mower will run for 10 years or more, while a battery-powered mower will need to be replaced after about five years, on average.
If bought new and maintained, most lawn mowers will last between 8 and 10 years. However, homeowners should be prepared to replace the battery in an electric mower after about five years.
It is quite normal for your car engine to vibrate at optimum levels during operation. The rotation of the crankshaft, transmission gears, and other vital components inside the car engine can cause slight vibrations.
Hand-Arm Vibration (HAV) is caused by the use of power tools. It can result in painful and disabling disorders of the blood vessels, nerves and joints. Hand-Arm Vibration Syndrome (HAVS) can be prevented, but once the damage is done it will be permanent.

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

ANSWER : There is a little spring that works the carburetor arm. If that popped off then the mower will not run.

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.
