First, check the battery terminals for corrosion; properly clean using baking soda and water. Now take a multimeter and place it on the terminals, and if your battery is 12 V, you should have a 12.7v reading. If it has a lower reading, try recharging the battery. If it still doesn’t work, then you will need to replace the battery. 

Battery replacement can cost anywhere from $60-$100, depending on your lawn mower model.

2. Dirty Air Filter: Clean the Filter 

Another common reason for mowers not switching back is dirty air filters. Combustion might be hampered by an air filter that isn’t allowing sufficient air into the engine. 

The mower will be covered in a thick layer of dust because you’ll be cutting grass with it. As a result, grass clippings might block the air filter, especially while mowing a damp lawn.

To clean the air filter, start by locating the filter and giving it a thorough cleaning with an air blower. In most circumstances, this ought to be sufficient, but if it isn’t, you’ll need to replace it. Replacement air filters can cost between $7-$10.

Depending on where you are, a solenoid replacement costs between $112 and $123. Additionally, labor expenses between $30 and $50 will be incurred.

4. Damaged Spark Plug: Clean, Tighten or Replace

Spark plugs are a crucial part of lawn mowers because they spark the fuel-and-air combination within the engine’s chamber. If the spark plug is broken, disconnected, or covered in carbon or water residue, it can be the cause of your machine’s malfunction.

You must thoroughly examine the spark plug. If the connections are loose, simply tighten them using a screwdriver and a wrench. However, for dirty spark plugs, try to clean them. If it is impossible to clean them, replace them with new ones. 

Replacement spark plugs cost very little; you will find them available for around $5, and you can replace them yourself.

5. Problem with the fuel pump: Clean or replace the fuel pump

This is one of the rarest reasons for the lawn mower engine not turning over. Your engine receives oil and gasoline through the fuel pump. However, the components of the pump might deteriorate over time as a result of the old gasoline remaining in the pump.

Check your fuel pump if there’s any fuel on top of it. If yes, then pump all the old fuel out of the pump and clean the pump correctly and remove all dust and debris. If the pump still doesn’t work properly, you will need to replace it.

Replacing fuel pumps typically costs from $880 and $1000. While parts are priced from $600 and $780, workers’ wages are predicted to be between $150 and $200.

Your Scott lawn mower may occasionally not turn over even though the battery is in good condition. The source of this problem is a faulty charging circuit, and as a result, the battery will be discharged faster.

Circuit components are quite critical, and it is very common for some components to get damaged or some wires to come off. This is a critical problem to detect by yourself, so you should visit a lawn mower dealership.
