6 Reasons of Cub Cadet Riding Mower Won’t Start (Easy Fixes Included)
Here are several signs that your Cub Cadet riding lawn mower won’t start and how to fix them.
1. Damaged Battery
The mower’s electrical system depends on its battery to operate; without a functional one, the engine won’t start and the mower won’t run. The battery won’t supply the necessary power to start the engine if it is weak or dead.
The mower’s battery may eventually run out of power, especially if it hasn’t been used for a while. Old age, lack of usage, or leaving the headlights on for a lengthy amount of time can all also cause the battery to get drained.
Try using a battery charger to recharge the battery if it is weak but still functional. If the battery has fully run out of energy or isn’t holding a charge, you might need to replace it.
Examine the battery connections for corrosion or debris; if so, the mower’s electrical connection may be affected. To clean the terminals of any corrosion or debris, use a wire brush or battery terminal cleaner.
Verify that the battery wires are secure and free of corrosion. The battery may be unable to supply power to the mower’s electrical system because of loose or corroded wires.
2. Spark Plug Issues
The spark plug may eventually become clogged with carbon or oil, which will stop it from sparking. This may occur if the mower is not properly maintained or if a filthy air filter is utilized.
The spark plug may be unable to create a spark if the space between its electrodes is either too large or too tiny.
You might try using a wire brush or a spark plug cleaner to clean a clogged spark plug. Check the manufacturer’s instructions carefully before cleaning the spark plug.
You might need to replace in a new spark plug if the old one is worn out, broken, or incapable of being cleaned.
Use the proper spark plug type for your Cub Cadet riding lawn mower, and then adjust the gap as recommended by the manufacturer.
3. Faulty Fuel System
The engine might not function and the mower might not start if the gasoline tank is empty. Also the fuel filter may clog up with dirt and debris over time, preventing gasoline from reaching the engine and resulting in the mower not starting.
Old or stale gasoline in the fuel tank may not support combustion and cause problems with the engine.
Ensure that new gasoline is poured in the fuel tank. It is required to change or thoroughly clean the fuel filter if it is blocked.
The carburetor might need to be cleaned or replaced if it’s unclean. Use brand-new fuel whenever possible, and don’t keep it in storage for a long time.
Check for efficient functioning or repair the defective fuel pump if necessary if the Cub Cadet riding lawnmower is equipped with one.
4. Broken Safety Switches
The seat switch, brake switch, PTO switch, and ignition switch are just a few of the safety devices found on a Cub Cadet riding mower. The lawnmower could not start if any of these switches are not working properly.
The mower could not start until someone is seated on the seat, for instance, if the seat switch is malfunctioning. The mower could not start if the brake switch is broken unless the brake pedal is used.
The safety switch itself might be broken or defective, which would make it impossible to start the mower.
Make that the seat switch, blade engagement switch, and other safety switches are in the appropriate positions by checking them. If not, make any necessary adjustments or switch replacements.
Check to see whether the problem is fixed by adjusting or cleaning the switch. If necessary, modify or replace the switches after making sure they are making good contact.
5. Clogged Carburetor
Many issues that may make the engine difficult to start might result from a dirty or clogged carburetor. It may hinder the proper quantity of air from blending with the fuel, which might lead to a weak or nonexistent spark.
To resolve these problems, consider using carburetor cleaner on the carburetor and its jets, changing the defective float valve, and checking and adjusting the stuck choke.
Checking the spark plug and air filter to make sure they are clean and working correctly is also a good idea.
