If you use a professional riding mower, you must know the starter motor and solenoid are very important. If these two parts are wrong, your mower can’t start. You will waste time and money. Today I tell you how to choose and maintain these parts, easy to understand, easy to use.

First, let’s talk about the starter motor.

The starter motor is like the heart of the mower. It drives the engine to start. Professional riding mowers work very hard. They run for long hours, in dust and wet grass. So you can’t use cheap or wrong starters.

Most professional mowers use 12V. You must match the voltage. If power is too small, the starter is weak. If power is too big, it may burn the wires. Just use the same as your original part.

For professional mowers, gear reduction starter is better. It has strong torque, small size, more durable. Old direct drive starters are not good for heavy work. They easy to break.

When you buy a new starter, check these points:

• Same voltage

• Same mounting holes

• Same gear teeth

• Same shaft length

If not match, you will hear loud noise. It will damage the flywheel. 

Next, the solenoid.

The solenoid is a strong switch. When you turn the key, it sends power to the starter.

Many problems are not from the starter, but from the solenoid.

Common problems:

• Only click sound, no start

• No sound at all

• Starter keeps running after engine starts

When you choose solenoid:

• Must be 12V

• Same pins: 3 pins or 4 pins

• Same wire position

• Good quality, pure copper coil

Don’t buy cheap solenoids. They easy to burn. Contacts will melt. Sometimes the starter can’t stop. It’s very dangerous.

Now, maintenance tips. These are very useful.

1. Keep wires clean and tight. Bad connection makes starter weak and hot.

2. Clean grass and dust often. They make parts overheat.

3. Don’t hold the key too long. Each start less than 5 seconds. Wait 10 seconds before try again.

4. Check the battery often. Weak battery hurts starter and solenoid.

5. Use good quality parts. Don’t buy cheap universal parts.

If you follow these tips, your starter motor and solenoid will work long time. Your mower will start easily every time. You don’t need to repair it often.

For people who use riding mowers for work, good parts mean good money. Choose right, maintain well, you save time, save money, work more efficient.
