1. Move To Basics If The Cub Cadet CC30 Isn’t Starting

Oftentimes, the Cadet CC30 won’t start or move. This problem may seem crucial but in usual cases, it’s not. However, there are quite a few reasons behind this but the good news is that these reasons aren’t very serious most of the time and their measures are hidden in the basics.

There is a PTO switch under the steering. If that isn’t pulled out, the CC30 mower won’t start. Make sure to pull that out before starting. Another thing is, making sure the battery terminals are connected tightly.

If both of those scenarios are in your favor but your CC30 is still not starting, check if both the spark plugs are properly plugged in. Also, check your fuel filter. If your fuel filter is quite a few days old, it’s better to go with replacing this one.

Most of the solutions won’t cost you any money. But in the case of replacing the fuel filter, it will cost you not more than $16-$17.

2. Check The Tire, Deck, and Blades For Uneven Cuts

The Cub Cadet CC30 mower cutting grass in an uneven manner is yet another common problem. Usually, the reasons behind this problem are pretty normal and obviously not a matter of headache. You won’t have to toil a lot or break your bank for fixing those issues.

It takes place if there is imbalance with the tire pressure or the deck isn’t adjusted properly.

First of all, before making any kind of move, make sure to check if the tire pressure is in the required state or not. The required tire pressure for the CC30 mower is 14 PSI for the front ones and 10 PSI for the rear ones.

If the tire pressure is okay, you need to go with properly adjusting the deck. You will find the entire labeling adjustment process in the user manual.

But what if both the above-stated solutions don’t work? Then check the blades. Maybe they have worn out and if that is the case, you will have to replace them. A new set of blades will cost you around $33-$34.

3. Fix The Battery To Solve The Clicking Sound When Starting Issue

The Cub Cadet CC30 may start making a clicking or chattering noise when you try to start it. This problem takes place mostly because of battery issues. But there can be other reasons as well.

Make sure the battery has enough charge. If it’s low on power it will make that sort of noise. Also, check if the wires that connect the battery to the solenoid and heavy black cable are properly connected. If they are loose or not properly connected, the problem will remain.

Furthermore, there can be problems with the solenoid. See if it is properly grounded to the frame. Also, if the solenoid is faulty, making a replacement is a must and it will cost you around $16-$17.

However, there can be other unidentified problems for which you should call the experts or reach out to the company’s support.

4. Take Left Turns And Adjust Deck For Uncut Grass Striping

The Cub Cadet CC30 mower has twin or two blades and they are designed in such a manner that the right side is for discharging. Also, the right blade is placed a bit backward or behind the left blade.

So, when you take left while riding, the cutting overlap is properly maintained. That’s why, whenever you ride your Cadet CC30 to cut grass make sure you take left turns most of the time to get the best outcome.

Moreover, if the cutting deck isn’t adjusted properly, this problem will show up. So, make sure you adjust it in the right way. Use the user manual. However, if you fail to do that, it’s better and safe to consult with someone who is an expert in this.

5. Replace The Pulley Belt, Idler Bracket, And Tension Spring If The Cub Cadet CC30 Slows Down Going Uphill

Sometimes the CC30 starts slowing down while going uphill. This thing is pretty obvious and happens for almost all kinds of vehicles. But there can be a few legitimate reasons behind this problem.

First of all, check if the pulley driving belt is worn out or is in working condition or not. If it’s not in working condition, you must replace it. If there is no problem with the belt, check the tension spring and idler bracket.

See if they are worn out or somehow got damaged or not. If these are also not in good condition, replace them.

The pulley driving belt won’t cost you more than $25-$26 dollars. The idler bracket will cost you around $33-$34 and the tension spring around $9-$11.

However, while replacing these materials if you face any difficulties or in plain words you don’t know how to replace them, consult with an expert.

6. Check The Gear and Deck If Engine Shuts Off

There are times when the engine shuts off while the cutting deck is working or engaged. This is yet another commonly witnessed issue.

Check if your Cadet CC30 is in reverse gear or not. If it’s in reverse gear and the cutting deck is engaged, the engine will shut down. This is a part of one of their automated safety measures.

Also, don’t forget to check if there is any sort of object stuck in the deck or not. If anything gets stuck in the deck, the engine will eventually shut down. So, make sure to keep an eye on that.
