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 :

Your Mower Won`t Start:

Other possible causes include: Loose, Dirty or Disconnected Spark Plug in Your Lawn Mower: Check it out, clean off debris, re-connect and tighten. Dirty Air Filter: Clean or replace. Fuel Not Reaching the Engine: Tap the side of the carburetor to help the flow of gas.

Two thousand hours is generally the number you`ll hit without any major repairs.
The symptoms that indicate a bad solenoid on a riding mower are difficulty starting the engine, engine stalls or shuts off suddenly, reduced engine power and performance. Moreover, it would also go through a decrease in fuel efficiency, and an unsteadiness in idling, lastly, the engine cranks but doesn`t start.
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.
Starting relay position

The fuse box (also called the power box), the instrument panel under the fuse panel, or the right fender are all possible locations. In most cars, it will be under the hood, in a large box with a black lid. This is where car fuses and relays are installed. It is also called a fuse box.

A dirty filter chokes off air to the engine making it hard to start so check to see if yours needs to be replaced. If you need a new filter be sure to use the original manufacturers part or the correct Toro replacement. These can often be purchased at your local Toro dealer or a home improvement store.
The average life expectancy of one of these commercial grade engines is usually 3,500 hours with oil change intervals of 50 hours. Typically at 2,800 you can start to notice a lack in power, usually do to low compression.
Yes and no. It`s not much at all if you happen to buy one that has all good quality parts, especially the deck, engine and transmission. I won`t name names, but there are plenty of makes out there these days that will have MAJOR problems within that five hundred hours, WITH proper maintenance.
Rusting, power failure, irregular pressure, missing equipment, an incorrect amount of voltage or current, dirt stuck in the system and corrosion are some of the possible reasons why a solenoid valve may not properly close or open.
When a solenoid is first energized, its coil receives a pulse of high inrush current that decreases as the plunger closes. If the plunger does not close, the high inrush current continues, which can cause the coil to overheat and burn out. This is the most common cause of solenoid failure and spotting it is easy.
Solenoid coil failure can be caused by a number of factors. Applying an incorrect voltage to the coil will cause it to fail and may cause the coil to burn out. Electrical surges or spikes may also damage the coil. Burnt out coils cannot be repaired and will need to be replaced.
Incorrectly wiring a starter will have a huge impact on how well it performs. “Bigger displacement requires you to rethink things, just like with fuel delivery, valvetrain parts, and so on. The starter got bigger and the output grew, so the wire must get bigger too.
An inability for the solenoid valve to operate may prevent your car from downshifting, and the engine will continue to rev as you attempt to brake. You may discover that the transmission will not shift out of neutral, as the solenoid is not receiving the proper signals or opening enough to shift the transmission.
Bad Wiring

Poor and hurried wiring lead to either inadequate current supply to the starter solenoid or a more dangerous problem of shorting. Both can make a starter solenoid to malfunction and cause starter system problems. Bad wiring instances include terminals that are left loose or connected the wrong way.

Loud popping, knocking, and stuttering noises from the hood of your vehicle are cause for concern, and could be a sign of major engine damage.
Use Carburetor Cleaner

Fortunately, you can generally do this without even taking the carburetor out of the engine. Start by purchasing some commercial lawnmower carburetor cleanerOpens a new window, which comes in a simple spray can and will make it easy to clean the inside and outside of the carb.

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 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.
This lawn mower is equipped with a self-charging electric start system that charges the battery while the engine is running. If the electric starter does not start the engine, the battery may need to be recharged.
Alternators power the small engine while it is running, keeping the battery charged by circulating power back through the system. For the easiest method to check your alternator, simply turn on the headlights to your lawn mower or outdoor power equipment. Then, turn off the engine.
Riding Mower Clicks but Doesn`t Crank

When you hear a click as you turn the key, a weak battery, bad starter solenoid, faulty wiring, failed starter motor or a seized engine could be the cause. This DIY troubleshooting will help you figure out what to fix.

A dirty carburetor is the most common cause of a Toro lawn mower won`t start. Other possible reasons include the following: Fuel Valve Off. Choke Not On.

In some cases you may need to remove the engine shroud on the top to get at the bolts…not a hard job..if more the one wire…mark them or draw a diagram as where they were attached..good luck

Toro recycler will start until primed gas is consumed.
ANSWER : I had similar problem and cleaned the spark plug and that seemed to have worked, but I think that may be a temporary fix because the engine still seems to be running unevenly. I feel that it must be a larger problem with the carb. If anyone can help this novice to adjust the carb or clean both carb and filter, or offer other solutions I would appreciate your assistance.

I need the wiring diagram for the solenoid/1999 16hp hydronamic Simplicity
ANSWER : The two big terminals are one fom the battery and the other to the starter.
The two smaller ones one comes from the ignition switch and the other might just be a ground.
Test becareful is hook the battery and starter wires up; take a wire and stick one on the battery terminal and tap each of the smaller terminals; when you get a click that will and should fire the stater; make sure it is out of gear or it will start. remember that terminal and hook the ignition key to it. check the other smaller terminal is or isn’t a ground one.
