Cub Cadet Challenger 750 Problems

  3. Transmission Issues
  4. Engine Suddenly Shuts
  5. Steering Problems
  6. Secondary and Primary Clutch Housing Issues
  7. Broken Muffler

1. Too Hard To Shift

Cub Cadet UTV users report experiencing a hard shift even while using their UTVs for light jobs. The Cub Cadet Challenger is not an exception.

We come across customers who are concerned about the shifting. It works fine until around 200 hours, then this issue arises.

Most users say the shifting lever becomes hard to shift, which causes problems while operating the machine. Having too much oil in the primary clutch housing is the biggest culprit for this.

The poor design of the shift system does not help either. You could ensure you have the correct oil level in your Cub Cadet Challenger 750.

Sometimes, lacking enough acceleration to shift to a certain gear also causes this problem.

If persistent, try accelerating the Cub Cadet Challenger to the correct RPMs before shifting. Mostly, you’re required to brake while shifting.

The solution

If clutch problems caused this, try cleaning the primary clutch before going for a test drive.

If you live in one of the unforgiving cold states, the issue could be the greasing. It’s advisable to stop using grease. Instead, try using Moly Dry Spray.

2. Shifting Lever Issues

Of the few Cub Cadet Challenger 750 problems reported by customers, this is the most common.

The lever issue comes up when users are trying to shift into reverse gear. The Cub Cadet either delays the gear engagement or refuses to engage.

Replacing the built-in accessories with different parts causes shifting problems after returning the parts.


When replacing parts on your Cadet Challenger 750, empty all the attachments and clean them before returning them to the machine. Also, check the gears to ensure there’s no debris or dirt.

3. Transmission Issues

Most Cub Cadet Challenger 750 users say they sometimes engage the reverse gear, only for the machine to grind while backing up.

Sometimes it’s a clutch problem—where the gear does not engage, but in most cases, it’s a transmission problem.

Transmission problems occur when the Cub Cadet Challenger 750 runs on oxidized or old hydraulic oil. A faulty transmission part could also be the reason.


We suggest taking apart the transmission of the Cub Cadet Challenger 750 and cleaning it. Check for and replace any faulty parts.

Next, put new fluid before putting it back. With this, you’ll be guaranteed that the transmission is not faulty.

After that, fix the clutch issue by adjusting it. Ensure all the gears engage properly.

4. Cub Cadet Challenger 750 Engine Suddenly Shuts

The engine of your Cub Cadet UTV may suddenly turn off. This happens after using the vehicle for some time.

You’ll notice when you turn on the ignition, it just cranks away. Cub Cadet won’t start if it’s running on overheated engine oil.

This Cub Cadet Challenger 750 model lacks an oil indicator, which can be blamed for this common problem.

Users don’t know how much oil there is. They end up overusing the oil without refilling or replacing it. This causes engine overheating issues.

A clogged air filter also causes sudden engine stops. With a clogged air filter, the engine does not receive enough air. It ends up overworking to produce enough power.

A faulty spark plug will cause engine problems to the most powerful engine and your cub is not an exception.

Having old or dirty fuel will also cause the engine to stop suddenly because this fuel does not burn properly to produce enough power.

If engine oil is the issue, we recommend solving it by refilling the oil to normal levels and cleaning the oil filters.

Also, check your air filters and ensure they’re clean and they allow enough air into the engine. Remove any faulty spark plugs and replace them with new working spark plugs.

You might also need to check the quality of the fuel you use. If it’s old or poor quality, use newer fuel. If none of this fixes the issues, contact your dealer to rebuild the engine.

5. Steering Problems

With a two-wheel drive vehicle, you expect the steering to feel light. You hope this is the case for the Cub Cadet 750 until the drive lock sets in motion.


You can solve the heavy steering problem of your Cub Cadet Challenger 750 by taking the steering out and spraying it with lubricant. That is if you don’t get used to the heavy steering.

6. Cub Cadet Challenger 750 clutch problems

The Cub Challenger 750 has two clutches; primary and secondary clutch. It is the clutch system that connects the engine to the transmission systems.

If any of the clutches fail, you can expect transmission problems. Your Cub Challenger 750 may also experience gear engagement issues because of a loose clutch belt or a worn-out belt.

The clutch belt powers the clutch. If it’s loose, it works inefficiently. A loose clutch belt sometimes slips and eventually causes transmission issues.

Another reason is: the clutch may have come loose due to wear. Most people are unaware, but you can adjust your Cub Cadet Challenger 750’s clutch to improve it.


First, try changing the clutch fluid by removing the clutch lines. That’s because, without proper clutch fluid, the clutch system will not work.

You should also tighten a loose clutch belt and replace a worn-out belt. If all the above does not work, try replacing the clutches.

7. Broken Muffler

The broken muffler is not a common problem among Cub Cadet UTV users. If your machine has a broken muffler, you’ll experience loud rumbling sounds from the machine.

A crack or a hole in the exhaust pipe or muffler will also result in Cub Cadet Challenger 750 problems. When you press down on the accelerator pedal, your vehicle will make more noise.


As a precaution, if you have a broken muffler problem, stop the vehicle because it can cause a serious accident.

You should take it to a professional mechanic immediately to fix the problem or use the manual.
