5 Most Common Cub Cadet Challenger 750 Problems and Fixes

The Cub Cadet 750 is a practicable UTV, running on a robust 735cc engine. It is ideal for farm surveillance and outdoor adventure. Its bed sprayer allows you to tend to shrubs and young trees in your lawn.

However, like any utility vehicle, you should expect some Cub Cadet Challenger issues. The most common Cub Cadet Challenger 750 problems are stiff steering, transmission issues, engine failure, overheating, shaking, and wobbling. Recurrent hiccups with this UTV originate mainly from the engine, transmission, and steering unit. 

Do you own a problematic Cub Cadet 750, or are you interested in purchasing one? Read on for an in-depth view of Cub Cadet 750 problems and how to solve them. 

Steering Problems

According to Challenger 750 reviews, one of the 750 Cadet downsides lies in the steering system. While the steering wheel may seem light in two-wheel-drive mode, it becomes stiff when you engage the other wheels.

This issue is manageable, and you may get used to it with time. However, the steering wheel may become more rigid with time, making it challenging to drive the UTV.

The problem, in this situation, probably lies with the electric motor in your UTV’s power steering unit. Dust, overheating, and coming in contact with water are some causes of motor issues. Also, the circuitry and the electric board may be faulty.

How To Fix Steering Issues

If your steering wheel is stiff, you should turn off the engine and turn it on again. Start driving slowly to test the wheel’s maneuverability. If it picks up, then it is ok. Check the power steering assembly if the wheel is still stiff.

At times, you may notice noises when steering, especially when driving fast. You should dismount the steering assembly and probe the functionality of parts like the motor and circuit board.

In case of any damage, replacement is the best way to go. Please replace the entire electrical unit of the power steering system.

The Engine Suddenly Shuts Off

The engine is the source of various Cub Cadet Challenger 750 problems, including suddenly shutting off. You may encounter this problem due to issues with the fuel system, the electrical unit, or the injection. 

In the case of the fuel system, you may have inadequate fuel or have used poor-quality gas. Issues with the electrical unit are the probable cause when the vehicle fails to start. The other possible genesis of this hiccup is a dirty or clogged air filter.

How To Fix Engine Shut-off Issues

You should have sufficient fuel in the tank and ensure it is of the right variety, per the manufacturer’s recommendations. You should clean the gas tank and line if you use the wrong or low-quality fuel. Cleaning is also the solution for contaminations, mostly from debris that can clog the fuel line. A vacuum pump is handy for severe clogging.

Moreover, you should attend to a dirty air filter, as it may put a lot of pressure on the engine and affect fuel consumption. Replace it if it is worse off. Get new spark plugs if the ones you have are worn-out.

Transmission Issues

You may experience transmission issues when shifting the gears and notice a grinding sound. At times, the reversal gear may fail. Other symptoms that point to transmission system problems include a burning smell when driving, grinding, and shaking.

How To Fix Transmission Issues

Check the transmission fluid levels and fill up if low. The fluid may sometimes leak, explaining why it is running low. You may notice this issue from pools of the transmission fluid where you parked the UTV. You can weld the part with the leak or get a new system to prevent a repeat of the problem.

Probe the gears and other related components to see if they are functional. Broken gears need a replacement. The other cause of transmission problems is air in the fluid. Bleeding the system is ideal for expelling the air and restoring the unit’s functionality.

Shaking and Wobbling

Still, on frequent Cub Cadet Challenger 750 problems, you may encounter shaking and wobbling when driving your 750 UTV. The cause depends on the nature of the shaking.

Minor vibrations indicate a problem with the engine, especially if it has a rough idle. The spark plugs are the main culprit behind such an issue, though the fuel line and air filter can also be the source.

For excessive shaking, the issue may be due to misaligned wheels, a flat tire, or an extremely rugged terrain.

How To Fix Shakes and Wobbles in Your UTV

If you are dealing with vibrations, you should inspect the engine with more focus on the spark plugs. Replace old or bad spark plugs for optimum engine performance. Additionally, clean the air filter and use high-quality gas. 

You must correctly align the wheels of the Challenger 750 for stability when tackling the road. Let a professional from Cub Cadet service centers handle the job.

Adjust your driving depending on your terrain. Be slow and tactical if the road is rugged to avoid excessive shaking. Never drive on a flat tire, as you will damage other UTV’s suspension system parts.


The Cub Cadet 750 will occasionally overheat, which affects its performance. Causes of overheating include radiator malfunctions, low engine oil, and inadequate coolant.

Signs of this engine trouble are:

  • Excess smoke or steam from the hood
  • A hiked engine temperature
  • Loss of power
  • A sweet scent from the engine, indicating burning coolant
  • A strong burning odor: the engine oil is burning

How To Fix Overheating in Cub Cadet 750

Switch off the UTV’s engine and let it cool before you address the complication. The radiator is the regular source of this problem, mainly due to dirt and bent fins. Clean the radiator, straighten the fins and refill the coolant. Moreover, change the engine oil regularly to avert overheating.

Final Thoughts

The Cub Cadet 750 is an excellent farming and recreation utility with selling points like comfort, decent towing, and cargo payload. However, this UTV is prone to several issues.

Cub Cadet Challenger 750 problems affect the steering unit, transmission, and engine. You can avoid these issues by routinely servicing your UTV.
