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 :
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.
A Husqvarna riding mower commonly dies when blades are engaged because the grass box is not fully closed. Other possible causes include: Grass Box Misaligned. Grass Box Sensor Wiring Loose.
If all blades are rotating at the same time, there is no issue with the cutting deck belt that is connecting the blades. If one, or more, blades are not rotating, the cutting deck belt is worn out and needs to be replaced. This should be done by an authorised dealer.
Mower blades are spinning 4000 RPMs. An unbalanced blade spinning that fast will cause a significant amount of vibration, which will put stress on yout blade shaft, spindle, and even the engine.
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.
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.
For riding mowers using a manual clutch, the mower blades are engaged by manually shifting a lever that moves a pulley assembly to tighten the blade drive belt. The rotating engine shaft will then drive the belt, which in turn, rotates the pulleys to spin one or more cutting blades.
Pull the switch up to engage the blades and push the switch down to disengage the blades. 7.6 Deck Lift Control—The deck lift switch is used to raise and lower the deck. Pull the switch backwards to raise the deck and push the switch forward to lower the deck.
Over time the air filter will need to be replaced as it becomes clogged with small particles and debris, starving the engine of air, causing a loss in power. Locate the air filter cover on top of the carburetor and remove it. It may be attached by screws or just a tab. Once off, remove filter, replace, and re-assemble.
The spark plugs are worn or damaged If you find that your lawnmower keeps dying, or keeps stalling while cutting grass, then inspect the spark plugs. Look for signs of damage or wear. Something as simple as a cracked porcelain insulator can mean an electrode has been damaged or burned away.

Kohler engine 15.5 turns over but will not start
ANSWER : Hi hoho641…
Make sure you are getting spark at the spark plug, to do this:Remove your spark plug and check to be sure you are getting fire at the spark plug.You do this by grounding the plug on the head of the engine and pulling the crank rope, if you are getting spark then:
Sounds like you have dirt/debris in your caburetor jets,fuel passages or a diaphgram that is becoming non-flexible. Check/Clean/Replace your Air Filter, a dirty air filter can make your engine run to rich with fuel.
Note: ALWAYS USE COMPRESSED AIR TO CLEAN YOUR JETS AND PASSAGES, VERY IMPORTANT.
Note:Before you disassemble the carburetor:Mark each piece with a awl, or some kind of instrument that will make an alignment scratch before you disassemble the carburetor into separate pieces.That way you will know which way it goes back together when you reassemble it.
Sometimes you can get by with priming the carburetor or by using starting fluid 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.Be sure to check your fuel tank for water and dirt/debris, if there is water/debris then you need to clean your tank.Check you fuel line condition after a while they will degrade and need replacment.
Check/Clean/Replace your fuel filter if you have one.Make sure you are using fresh fuel.If the moweris over a couple of years old, then I recommend that you buy and install a new carburetor repair kit,because the diaphragm will get hard and that will cause it to be hard to crank.The diaphgram may look good and flexible, but it can be deceiving and not act as a fuel pump as it should because it has become too hard and will cause hard starting,start and run and shut off, etc.
When you clean your carburetor, I recommend that you use a laquer thinner type cleaner to clean and dissolve the laquer build-up in the float and needle jet passages.Be sure to remove all plastic and rubber parts before using the laquer thinner because it can dissolve the plastic parts and render them unuseable.Be sure to use COMPRESSED AIR to blow out all the fuel and air passages.The higher air pressure is needed to blow some of the trash/debris from the fuel or air passages.Be careful when blowing out the passages, because there are sometimes small rubber type seats in the bottom of some of the passages.Keep in mind that the float (if you have one) for the carburetor must be level when you go to reassemble the carburetor or follow the instructions you get with the carburetor kit, or you could also ask the parts man that you get your kit from.When you clean your carburetor and remove the jet screws, you will first need to lightly seat the jet screws.But before you lightly seat the jet screws count the number of turns it takes to seat the jet screws from their original position.Be sure to mark the turns down on a piece of paper.That way when you put the jets back in, you know to lightly seat them first and then turn them back out to their original position before you started.
After you have the carburetor rebuilt that should solve you starting problem.

ANSWER : I’ll bite, what’s your question Mike? If you are looking for a how to, you can probably find it at the manufacturer’s website, without going into too much detail however I can offer you a general approach.- Remove the front hood of the mower and the shroud if it has one.- Disconnect the carb, and exhaust and move it aside.- Remove the Spark plug- Carefully remove the valve cover in the front of the engine.- Look up the proper valve adjustment settings for your model.- Get the engine at top dead center.- Take measurements and adjust the valves accordingly.- Clean the valve cover itself, and where it’s going to be seated.- Apply a thin coat of gasket sealant, put the cover back on.- Wait for the sealant to bond (depends on manufacturer specs_- Fire it up.Keep in mind, this is a general guide, see your manufacturer’s manuals and technical diagrams for more details.
