Stiff steering is one of the most common issues faced by Cub Cadet 6284 tractors. When this happens, you won’t be able to turn your steering properly and will feel like it’s stuck.

There can be many reasons for this problem, like dirt in the shaft, lack of lubrication, and damaged inner bushings.

To solve this problem, you will need to look at your steering internals part by part.

Step 1: First, lubricate the shaft of your steering very carefully and make sure to remove any dirt on the internals.

Step 2: If step 1 solves your problem, then you do not need to come here. But, if it doesn’t, check the inner bushings for any damages; in case of damage, you will need to replace them.

Replacing inner bushings can be quite technical, so you might need to visit a repair shop where the cost can be anywhere from $150-$500.

2. Broken Deck Belt: Replace Pulley and Remove Any Debris From the Deck

On a Cub Cadet 6284 tractor, the deck belt wraps around the pulleys. However, it is susceptible to breaking under excessive stress. If your tractor deck belt keeps breaking, then there can be multiple reasons for that.

First of all, the belt itself might not be of good quality. Then there can be problems with the Pulley itself. Also, the belt can break down when the deck is clogged up with debris and grass clippings. To fix this issue, follow the steps below.

Step 1: Before you start with any repairs, make sure to check the tension on the belt, and whether or not it is enough for the load you are carrying on the tractor. Replace it if needed

Step 2: If your belt is okay, then turn over your tractor and clean the deck if it’s clogged due to grass clippings and debris

Step 3: Check the Pulley for any damage and replace it with a new one if necessary.

A good set of tractor pulleys and belts will cost anywhere between $40-$60. If you hire a mechanic for the work, the cost can rise up to $100-$200.

3. Smoke Coming Out: Drain and Change Engine Oil

When you try to start your Cub cadet tractor and see excessive smoke coming out of the engine, that means too much oil is going into the engine. It is a very common problem, especially when you overload your tractor with oil. Another potential reason is contaminated oil.

The solution is really simple for this problem. Pressure can build up inside when too much oil flows into the engine. Therefore, all you need to do to stop the smoke is drain some engine oil.

Now, if your tractor has been sitting ideally for a while, the fuel in the tank may become polluted with dust and air. The best course of action is to flush your fuel tank and refill it.

4. Tractor Stops Running: Clean Air Filter and Cooling Fans

If your Cub Cadet 6284 compact tractor often stops working suddenly in the middle of work, then there are internal problems inside your tractor. So before fixing it, you will need to detect the exact reason for this issue.

Step 1: Find the air filter, which is usually placed inside your tractor’s engine. Read the manual to find the exact locations of the air filter.

Step 2: You will see a housing inside the engine where there is a filter. There might be bolts stuck to the filter; unscrew them and remove the filter.

Step 3: Check if the air filters can be cleaned; blow some air to remove dirt. If it is beyond cleaning, just replace the air filter.

  • Dirty Cooling fans

The cooling fans are really important in your tractor and keep the engine cool. Dirt and grass might obstruct cooling fans. Simply cleaning the cooling fans at least once every two weeks is all that is required.

Air filters are cheap, and it will cost around $3-$10 to replace them.

If your tractor is vibrating more than usual while running and your engine is having a hard time starting, there can be faults or damaged spark plugs. Unfortunately, spark plugs can’t be repaired, and you must replace them.

Step 1: Changing spark plugs is a straightforward process. Before you begin, park your Cub cadet 6284 tractors on an even, flat surface and turn off the engine.
