Cub Cadet 6284 Problems and Solutions

Here are the known problems together with their solutions:

1. Stiff Steering

This problem causes difficulties when turning or navigating the tractor around tight corners. The steering will feel like it is resisting. And you may hear strange noises when attempting to turn the wheels. 


  • Check the tires and ensure they are properly inflated. 
  • Inspect the steering linkage and lubricate any dry or rusty parts. 
  • Tighten any loose bolts or nuts that you may find. 
  • Check the steering wheel and shaft for any damage or wear, and replace them as necessary. 
  • Finally, check the steering gear or box for any obstructions or debris and clean or replace it as necessary. 

Here is a video illustrating how you can fix this issue:

2. Broken Deck Belt

The deck belt drives the blades that cut the grass. When it breaks, the blades stop turning. You may hear strange noises from the deck, and the tractor may not cut the grass evenly. 


  • Ensure that the mower is powered off and remove the deck belt from the mower. 
  • Purchase a new belt that matches the exact model of your lawn mower to ensure compatibility. 
  • Install the new belt by attaching it to the pulleys and threading it through the necessary parts. 
  • Make sure to check that it is properly aligned and tight enough.

3. Smoke Issue

The smoke can be white, blue, or black and have different causes. For this model, you will mostly have white smoke.


  • Check the oil level. Smoke can indicate too much oil in the engine. 
  • Remove the air filter and check if it’s dirty or clogged. If it is, replace it.
  • Check the fuel quality. Drain the fuel tank and replace it with fresh fuel.
  • Remove the spark plug and inspect it. Replace worn-out and dirty plugs.

4. Stalling or Stopping

Your Cub Cadet 6284 machine may stall or stop even when handling simple tasks. This model is built to withstand even the harshest environments. So, when it stalls or stops, something is up.


  • Check the fuel level. Ensure enough fuel is in the tank.
  • Check the fuel lines, filter, and carburetor for any blockages or damage. Check your fuel pump too as it can result in stalling when not working normally. 
  • Remove the air filter and inspect it. If it’s dirty, clean or replace it with a new one.
  • Check the ignition coil, spark plug wires, and other components for damage or wear. If any of these parts are damaged or worn, replaced them.
  • Check the seat, PTO, and other safety switches to ensure they function properly.

5. Excessive Vibrations

When driving in rugged terrain, you will experience vibrations. However, if you are on a good surface with no potholes and your machine vibrates, it could indicate a problem. These vibrations are no joke and can be uncomfortable for the operator. 


  • Start by disconnecting the spark plug wire for safety, and then inspect the blades for any signs of wear or damage. Also, check if the blade is properly balanced. 
  • Inspect the belt for any signs of wear or damage. If the belt is worn, replace it immediately.
  • Look for cracks, breaks, or excessive wear on the mounts. Try to move the engine back and forth to check if the mounts are loose. 
  • Find loose or worn parts of the steering, such as tie rods, ball joints, or steering linkages. If any parts are loose or worn, tighten or replace them as necessary.

6. Rough Engine

A rough engine can manifest in different ways. You might hear loud engine noises, including knocking or pinging sounds. The engine might hesitate or stall when you’re trying to start it, or it might not run at all. 

Sometimes, a rough engine can cause smoke or an unpleasant odor to come from the engine.


  • Check the air filter and clean or replace it as necessary. A dirty air filter can restrict airflow to the engine, causing it to run rough. 
  • Next, check the spark plug and replace it if worn or damaged. 
  • Inspect the fuel system for any clogs or obstructions. Ensure the fuel tank is clean, the lines are clear, and the filter is not clogged. 
  • Lastly, check the carburetor for any clogs or debris. Clean or rebuild the carburetor if necessary. 

7. Oil Leaks

Oil leaks can manifest in different ways. You might see oil dripping from the engine or other parts of the tractor. Thus, you might notice that the oil level is lower than it should be or that the engine is making strange noises. In some cases, the engine might overheat or stop working altogether.


  • Check the oil level to ensure it is not overfilled. 
  • Next, inspect the oil filter and drain plug for any signs of damage or wear. If either of these parts is damaged, they may need replacement. 
  • Check the gasket or seal between the engine block and the oil pan for leaks. If the gasket or seal is damaged or worn, replace it. 

8. Uneven Cuts

If your mower is leaving uneven patches of grass in your lawn, it’s likely that you’re dealing with an uneven cutting problem. Several issues can cause this. 

One of the most common causes is a dull or damaged cutting blade. When the blade is dull or damaged, it can’t cut the grass evenly, leaving some areas longer than others.


  • Use a leveling gauge to check the level of your mower deck. Adjust the deck height until it is level. 
  • Check the blades for any signs of damage or wear. If the blades are dull, sharpen them or replace them if necessary.
  • Check the tire pressure on all four tires and adjust as necessary. You should check it after every 50 hours on the mower.
  • Always clear the lawn of any obstacles before mowing. Rocks, sticks, and other debris can cause the mower to bounce and result in uneven cuts. 


From stiff steering to uneven cuts, there are several Cub Cadet 6284 problems that you may encounter when using this machine. But with the right maintenance and troubleshooting, you can keep it in top condition and enjoy a beautiful lawn all season long.

So, don’t let a few problems with this model discourage you. You can keep your mower running smoothly and enjoy a beautiful lawn with a little know-how and a positive attitude.
