Like any gas-powered engine, a John Deere Z915E will also stop if the fuel amount is insufficient. If there is no power in your Z915E, look for any improperly timed spark or faulty spark plug. Sometimes a John Deere Z915E engine does not get the proper amount of air, Spark, or fuel needed to prevent a loss of power.
Dirty or Clogged Air Filter
Since the filter of your John Deere Z915E is responsible for cleaning the air before it is drawn into its carburetor, the engine will have no power if it malfunctions due to any debris buildup. It is essential to address any clogged air filter that does not allow the proper amount of air to be drawn into the carburetor as soon as possible to reduce engine power.
Stale Fuel
If your John Deere Z915E engine needs more power, there might be wrong or dirty fuel. Make sure the energy is not contaminated or older than 30 days.

Dirty or Clogged Fuel Filter
If your John Deere Z915E fuel filter is clogged, the fuel flow will be restricted to the engine, causing no power. It is essential to clean the filter to remove dirt from time to time as a regular part of maintenance.

Tall Grass
If you continuously try to cut wet or tall grass, your John Deere Z915E may lose power while mowing through that terrain. It is essential to use the right kind of mower deck height settings to more tall grasses.
Improper Oil Level
If there is insufficient oil level, your John Deere Z915E engine will lack the power to operate correctly.

If the oil level is taller, the System’s ability will be limited due to inadequate lubrication and more load on its engine.
Faulty Spark Plug
You will notice inconsistent ignition if there is any problem with your Z915E spark plug. If you see any dirt, carbon, or oil buildup on your John Deere Z915E spark plug causing a loss of power, make sure to clean it.
