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 :

If the starter motor spins but does not crank the engine, you likely have a problem with… Faulty or damaged battery. To address this issues, check the battery and charging system for problems.
Look for the large terminal posts on the solenoid where the thick red wires connect to the solenoid. Touch the metal shaft of a screwdriver to both of the large terminals at the same time. If the engine turns over and starts, the solenoid is bad and should be replaced.
1 Start motor engages but the engine doesn`t turn

The simplest cause of this sort of fault is a loose or corroded electrical connection. If there is a fault with the internal windings of the starter motor, bad brushes, or other electrical faults, the starter motor may lack the torque to crank the engine.

A starter malfunction can have different causes: Electrical connections faulty. Solenoid switch (engaging relay) stiff or faulty. Electric motor damaged electrically.
One of the first and most common symptoms is simply no response from the starter when you turn the key – no noises or engine cranking at all. Sometimes, repeatedly trying the ignition can produce a result, but that`s not guaranteed. It usually means there`s a faulty connection in the solenoid.
If the starter engages but does not disengage when you let go of the key, the solenoid is likely bad and the starter may suffer significant damage as a result. Sometimes your car starts, sometimes it doesn`t. Intermittent operation can be a sign of a failing starter solenoid.
If your tractor is making a clicking sound when you turn the ignition, this may be a sign that there is an issue with your tractor starter motor. If you hear a whirring sound it may be due to the pinion gear not engaging with the flywheel.
The starter relay makes a clicking sound, but the engine does not rotate, which indicates that the starter motor is not receiving enough current from the relay. This may also be a sign of low or exhausted battery power. Only when it transmits enough current to the starter, the relay starts to work.
Starter motor issues can manifest as a single, loud click emanating from the starter relay or starter solenoid. Usually, this points to a faulty relay or solenoid, or a bad or jammed starter motor.
Starters Can Fail Due To Low Battery voltage

Welded contacts can cause the starter to stay engaged with the engines ring-gear and should the engine actually start the high revolutions will cause the starter to blow apart inside.

If the switch inside your ignition is stuck, it can continually cause your starter to crank. Faulty wiring or malfunctioning starter parts can also cause continuous cranking after starting your vehicle or removing the key.

Cub Cadet LT1050 lawn tractor won’t turn over and start. Starter motor does turn, but flywheel doesn’t turn very fast, and stalls each revolution at the top of the compression stroke. I can turn the flywheel past this point with my hand on the flywheel screen, although it is difficult. I first thought “low battery” but I jumped the tractor with a deep cycle marine battery and although i get very bright lights and good spark on the engine ground, the starter motor still won’t turn the flywheel past the high compression spot of the rotation. I’m guessing the starter motor isn’t generating enough torque, but I don’t know how to test for that. It does turn when hooked directly to the jumper battery. I’m not brave enough to try to stall it with my hand. Any ideas on how to diagnose this?
ANSWER : Three people i know plus myself have this same problem with this same model tractor. new starters and new batteries did not help any of us

How do I remove starter from 14 H.P. B&S vertical shaft engine?
ANSWER : Normally it hooks up to the engine at the top side where the flywheel is located..at the top you will find two small bolts..and at the bottom one or two wires..just disconnect the battery cables so no sparks or shorts when removing from the starter..then disconnect the starter wires set aside and then remove the two bolts..it should drop right out…note.. 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
