An excessive amount of vibration while operating the lawn mower is harmful to your tool. It typically occurs for a couple of reasons. Maybe the cutting blade is loose or properly not balanced during the installation process.

Besides, if the blade is bent or damaged, there will be excessive vibration. If the engine mounting bolts are loose or missing, there will be vibration. Furthermore, a failing clutch can cause vibration.

To solve the issue, you should check the blade and tighten it along with the spindle. If the blade is damaged, replace it. The cutting blade is easily available online or at any local tool shop. In that case, you may need to spend $15-$52 to get a new blade.

Also, check the engine bots and tighten them properly. If the clutch is not working properly, you need to replace that as well. The cost of a new clutch is anywhere in the range of $120 to $180.

2. Uneven Cut: Check Deck, Blade, and Tire

The lawn mower may perform uneven cuts which can be frustrating. There are several reasons behind the problem. Maybe the deck is not properly installed and leveled. If it is the main cause, you will need to adjust the deck from side to side.

Another cause can be a dull blade. In that case, you should try to sharpen it. If the efficiency of the blade is lost, try to go for a replacement. We already mentioned above that you will get the blade easily in any local tool shop or online.

If the tire pressure is uneven, you will not even get cut from the lawn mower. To solve the issue, you must perform a thorough checkup of all 4 tires’ pressure. Make sure there is even pressure in all tires.

3. Fails to Start: Find the Cause and do Appropriate Remedy

Sometimes, the Cub cadet pro z 100 won’t start which is quite frustrating. This problem can occur for many reasons. For instance, if the fuel tank is empty, the machine won’t start. In that case, refill the tank with fresh fuel.

If the spark plug is too dirty or damaged or there is a bad connection, this lawn mower will not start. To solve the issue, replace the spark plug and install it properly. Luckily, this part is not too expensive and you will find a decent one for under $10.

Besides, if there is too much dirt in the fuel filter, there will be no continuous fuel flow. It is another good reason why this mower fails to start. To rectify the situation, you need to change the fuel filter. The cost of a decent fuel filter can be anywhere between $5 and $10.

4. Sudden Power Failure: Identify the Cause and Take Proper Remedial Steps

Sudden power failure means the mower stops working as it loses power. It can happen due to clogged air filters. The air flow will be interrupted if any dirt or grass plugs into it. If you identify this issue, you must clean it properly after removing it from the machine.

When the filter is damaged, you should go for a replacement. The price of a good quality air filter can vary based on the model and brand. But, you will get a good one in the price range of $6- $25. Another potential reason can be clogged fuel lines.

If the fuel quality is bad or there is too much dirt, the fuel lines will be clogged. As a result, fuel won’t be able to flow to the engine and the lawn mower will lose power eventually. You can clean the clogging in the fuel lines by using a carb cleaner. The cost of a new carb cleaner typically starts from $15.

5. Issue with driving Straight: Check Tire Pressure or Replace the Damper

Another common problem with this lawn mower is you will not be able to drive or steer it correctly. There are two main causes of this problem.

Firstly, the tire pressure is maybe unequal. That is why the mower always drives one-sidedly. The remedy is quite simple here. You just need to check the pressure of all tires. Make sure that there is even pressure in all tires.

Secondly, the reason could be a bad damper that forces the machine to turn one-sided while driving. In that case, you need to replace the existing damper to solve the issue. The price of a new damper will be somewhere between $25 to $100 depending on the models and brands.

6. Smokes Generation: Check the Oil Level

If fuel enters the cylinder and starts burning off, you may end up getting smoke from your lawn mower. Too much or too low oil in the engine may create this problem.

If there is excessive fuel in the crankcase, oil can get into the cylinder and create smoke. So, you need to be aware of the recommended oil level from the manufacturer. Drain the excess oil and the problem will be solved soon.

Another reason can be the low level of oil in the tank. In that case, it may create additional friction. Thus, an extreme level of heat will be produced in the engine. The remedy is adding more engine oil. However, if the engine is damaged somehow, you may need to take the mower to a local repair shop.

7. Inability to Move: Replace Drive Belt or arm spring and Bleed Air from the Hydraulic System

Many users also face this issue when the lawn mower doesn’t move. The problem can arise due to a bad or missing drive belt, issues in the idler arm spring, or the existence of air in the hydraulic system.

If the drive pump belt is missing or not working properly, the lawn mower will not move. If it is worn, you should replace it with a new one. Luckily, these belts are not expensive and you can get a new one for $20. Besides, you should also check the idler arm spring that places tension on the drive belt.

If it’s not functioning properly, you need to change it. Another potential reason can be the presence of air in the hydraulic system. If it is the cause, you should follow the user’s manual to bleed air from the hydraulic system.

8. Difficulty in mulching grass: Increase Speed, Sharpen or Replace Blade

It can be frustrating if Cub cadet pro z 100 doesn’t mulch grass properly. There can be a couple of reasons. If the speed of the mower is too low, you won’t get the expected output. In that case, you should increase the speed of the machine.

If the blade is too dull, it won’t mulch grass up to the mark. Either sharpen the blade or go for a replacement. There are some other reasons for this problem as well. When the grass is wet, the mower won’t be able to mulch properly. Try to avoid wet grass when it comes to mulching.

If the grass is too high, the mower won’t mulch properly. So, try to avoid higher grass to get better performance.
