How A Riding Lawn Mower Is Powered

Riding mower is powered by a four-cycle engine . Some mowers use gasoline as their fuel and a spark plug to combust it. Others are powered by diesel and require no spark plug. In either case, the engine runs the transmission and drive wheels, and rotates the cutting blades underneath the machine.

Like automobile car, riding mower requires to charge a battery, starter motor, and ignition switch. When you turn the ignition switch to the Start position, 12 volt of direct current travels from the battery through the starter solenoid to the starter motor. This current also flows through a cable to the anti-afterfire solenoid in the engine

When you release the key to the Run position, this DC of twelve volts is then redirected. Instead of going to the starter and motor, it moves to the alternator and anti-afterfire solenoid only. Together, these parts help to charge the battery and start auxiliary power sources like headlights and power plugs.

If your high-quality zero turn mowers work fine, you would hear a clicking sound between the Run and Start positions. This implies that the starter solenoid is getting power from the battery. On the other hand, when you dont hear a click from the engine, the starter has failed, or its coil isnt getting power from the battery.

Although mowers differ from models, they all work on the same principles.

• Accessing the battery, which is usually under the driver’s seat.
• Connecting the charger clips to the battery terminals.
• Plugging the charger to a power outlet. The charger should work on at least 10volts to charge the battery. Still, a 12-volt charger is sometimes preferred.

I have the same issue, except I’ve had it for a couple of years. Mine recently started misbehaving and not shutting off when blade control handle was let go, and took me pushing the little metal switch thingy on the mower in. I recently fixed that, and electric start worked for a bit, and then suddenly it wouldn’t start anymore. So I bought a new off brand mower only to have it suddenly start running slow, and it’s self propel quit working. It of course has an engine that needs primed . Then I managed to fix the mower after discovering the ground wire was half broken, so I redid the ground wire And replaced the cover and lo and behold it started but then later on electric start stopped working at some point. It still starts with the the pull cord, but also it will sometimes spit black exhaust out when starting. Not a lot, but once it gets up to speed meaning the engine, no color to exhaust which is good. But when you shut it off it smells strongly of fuel. I’ve done carb cleaner and fuel treatment and it runs better, but still does the black exhaust.
