2. Uneven Cut

First, check the blades if they are dull then you should sharpen them or replace them with new ones. 

Also, make sure that the air pressure in both tires is even. If one tire is low, it can throw off the balance of the mower and cause it to miss patches of grass. So, you should inflated both tires equally.

And also, take a look at the deck. If it’s not level or dirty, that could also be why your mower isn’t cutting evenly. So, you should clean the deck and level it.

Second, reason maybe the blades are dull due to which your mower require more power to mow due to which it loss power. In this scenario you should sharpen the blades because sharpening blades will reduce the load from your mower.

And also dirty air filter and spark plug can cause the engine to loss power. So, you should also clean both of them.

5. Hard to Start

If your Cub Cadet Pro Z 100 is having trouble starting up, these are a few possible causes. First, check the fuel level and ensure enough gas is in the tank. 

If gas is empty then you should first fill the gas tank with the quality fuel.

If the problem persists, it’s possible that the air filter is dirty. Therefore you should clean it however if this doesn’t work then you should replace it.

Also, you should make sure that the battery is fully charged.

If none of these solutions fix the problem, you may need to take the lawn mower to a certified dealer or service center for further diagnosis.

6. Not Mowing

If you’re having trouble getting your Cub Cadet Pro Z 100 to cut grass, these are a few things you can check. 

First, you should make sure that the cutting deck is leveled. An uneven deck can prevent the blades from making contact with the ground.

 Next, you should check the depth of the cutting blades. The blades should be set to a height that allows them to skim the grass’s surface barely. 

And the last thing, you should inspect the cutting blades themselves. If they are damaged or dull, you should replace them with the new sharp blades.
