2. Running Of Your Engine Erratically 

An erratic engine is a ubiquitous sign of a faulty machine; if not attended to immediately, your engine will likely die anytime soon.

Three primary running conditions lead to this problem; when you run the device with the choke on, stale fuel and a loose spark plug but some other problems include when your air cleaner is dirty or when a vent in the cap is clogged. 

In that condition, you should activate the choke control, clean the fuel tank, replace it with the right one, and connect the spark plug properly.

Sometimes the power might not even be stale, but it would be filled with dirt, needs proper cleaning, and then replaced with oil of the correct viscosity. Once you’ve done all these cleanings, your engine should be able to run correctly again. 

3. Starting Issues 

The cub cadet mower and several other mowers also experience starting issues. The cause of the matter is a bad engine, but you should be sure about the problem before you find a solution. Some reasons why your engine experiences difficulty in starting include; 

  • Insufficient or no airflow at all. 
  • When your spark plug wires are damaged. 
  • Incorrect setting of the throttle control levers. 

 You should also check the entire fuel system like the fuel pump, injector and fuel tank. Ensure you always use quality gasoline, check your spark plug occasionally, and change it if the need arises. Note that it is essential for you to place the knob in the disengaged position and also engage the parking brake. 

4. Smokes Emitted from The Lawn Mower 

Smoking from your cub cadet results from an insufficient amount of oil deposited and engine failures. Low engine oil can also lead to smoking. When this happens, ensure that you switch off the cub cadet mower and let it cool off for a while. After that, you can now replace the engine oil with more. 

When your cub cadet lawn mower emits smoke because of excessive oil that causes pressure buildup, you can remedy this by draining the right amount of oil so your mower can typically perform again. 

5. Mower Not Driving Correctly 

Many reasons affect how your cub cadet mowers drive. This is a result of either a lousy damper, tires with incorrect pressure or worn-out steering components. . if your tire pressure is unequal, ensure that you correct them as soon as possible and fill them up to the manufacturer’s spec. 

Bad dampers can also cause your mowers to jerk to one side and not move in a straight line like it is supposed to; in this case, it should be replaced with a new damper, ad if your steering component is loose or worn out, inspect and replace the parts with a new one. 

6. Excessive Vibration 

When you notice that your mower vibrates excessively when in use, the problem has to do with the cutting blade, whether it is loose or unbalanced or even bent. There is a straightforward fix: either you tighten your cutting blade and the spindle, or you replace the edge. 

7. Engine Overheating 

An overheating engine is a fatal case that you need to treat immediately to prevent accidents or a fire outbreak, which could be deadly. When this happens, check your engine oil to ensure it is at the right level, check if the cooling fins are dirty, preventing air flow, and check if there is sufficient gas or fuel. 

If the engine oil is under the average amount, ensure that you top it up; also, check your cooling fins to ensure that with debris or dirt.

When you have stale fuel, drive around for some minutes to provide that the fuel that settles underneath mixes properly before you finally empty the fuel tank and fill it with the right fuel. 

8. Uneven Cut 

Sometimes you notice that after mowing your grass, some parts are not correctly cut; this is either because you have a bent or blunt cutting blade, uneven tire pressure or an unlevelled deck. If your blades are the case, ensure that you sharpen, straighten or even replace your blades.

 Ensure that you check on the tire pressure of all four tires to ensure that they are all up to the right amount of air and level the deck so you would have a better cutting blade.
