Check the spark plug for dirt or carbon build-up; if so, clean it out with compressed air; if this doesn’t work, check your fuel filter for clogs and replace it if necessary. If neither of these fixes works, then it’s possible that the carburetor needs cleaning or adjustment. Contact customer service for further assistance if you need help solving your problem.

Common Cub Cadet XT1 Problems and How to Fix Them‍?

Common problems that Cub Cadet XT1 can cause are given below. We also have mentioned their solutions below:

Tractor Won’t Start

The Cub Cadet XT1 is a well-built, reliable tractor. However, it can experience problems from time to time that may make it difficult to start the engine. The most common causes of an XT1 tractor not starting include the following:

  • A dead battery
  • Low fuel pressure
  • A clogged air filter
  • Incorrect fuel mixture settings
  • Corroded wiring connectors

What To Check If Your Engine Of Cub Cadet XT1 Is Not Starting?

When the XT1 doesn’t start, check these things first:

  1. The gasoline level is low; add fuel to the tank and try again.
  2. The starter cord is not fully engaged; pull it in until you hear it snap into place.
  3. The engine may be flooded from an over-rich fuel mixture; allow several minutes for fuel to drain from the carburetor bowl before trying again.

Why does my Cub Cadet XT1 click when trying to start?

You may need help with the starter solenoid or the starter motor. The starter solenoid is part of the ignition switch assembly and can be replaced separately from the ignition switch. The problem could also be a worn-out starter motor, which may require replacement.

Causes of clicking noises:

The battery: A weak or dead battery can cause a clicking noise when trying to start the engine. Check your battery connections and charge your battery if necessary.

Starter solenoid: If you hear a clicking noise from under the seat, it might come from your starter solenoid. To check if this is the problem, remove all cables from the battery and try turning it over with someone watching the starter cable while you turn it over (keep your fingers away from moving parts). If it doesn’t start turning over again, there’s likely an internal problem with your starter solenoid, which needs to be replaced.

Why is my engine clicking and not starting?

The clicking sound is the starter motor attempting to engage the flywheel. The engine is not turning over because it is flooded (too much fuel). 

Possible reasons could be:

  • The engine is not getting fuel.
  • The fuel filter is clogged.
  • The fuel pump is broken.
  • The spark plug needs to be fixed.
  • The spark plug wire is broken or disconnected.

Steps you may take are explained hereunder.

Step 1: Check the carburetor. The carburetor controls how much fuel gets pumped into the engine. If no fuel comes out of the carburetor when you press on the primer bulb, then something’s wrong with that part of the system. You’ll need to take off the air filter and look inside for damage or clogs. Clear anything that looks abnormal and try again. If there’s still no fuel from the carburetor, it might be time to replace it entirely.


Step 2: Check the fuel. Ensure the fuel tank is full, and test the engine with a can of starting fluid. If it still doesn’t start, move on to step 3.

Step 3: Check spark plug wire connections. The spark plug wire sends electricity from the ignition coil through the spark plug and into the engine block, where it ignites fuel/air mixture inside cylinders inside pistons which produce power that turns the flywheel which spins the crankshaft, which moves the drive belt.

Step 4: Check the air filter, air cleaner, and muffler. The air filter catches dirt and debris before it enters your engine and reduces air pollution caused by emissions from gasoline engines. Clean or replace a dirty air filter to keep your mower running smoothly. The muffler reduces noise created by exhaust gases, but if damaged or missing, this can cause rough running of your mower’s engine. Replace damaged or missing dampers with new ones as needed to get rid of this problem completely.

Cub Cadet Xt1 Runs Rough And Stalls Out

When the Cub Cadet XT1 stalls out, it might be because of a dirty air filter. This article will show you how to clean your air filter.

First, remove the air filter housing cover. Then remove the air filter element by pulling it straight out.

You can then see an access hole in the top of the carburetor where you can insert a small flathead screwdriver or other tools to turn off the valve that controls the fuel flow into your engine. When we did this, we found dirt blocking one side of this valve inside our carburetor, and we had to use compressed air to clear it out.

Once you have cleaned the carburetor, you can start Cub Cadet XT1 up again without any problems!

Cub Cadet XT1 is Not Driving Smoothly


The Cub Cadet XT1 lawn mower does have a drive belt that can cause trouble if it starts to slip or stretch out. If the belt is loose, it will cause the engine to run rough and the mower to vibrate and shake. The first thing you should do is check the tension on the belt. If it is loose, tighten it by turning the pulley clockwise until it feels tight enough. You can also adjust the height of your wheels to see if this helps with your problem.
If adjusting these things does not solve your problem, you may need to replace your drive belt. A new one can be purchased at any local hardware store or auto parts store, so be sure to bring your Cub Cadet XT1 with you when shopping for one so that they can match it up with your model correctly. Once installed, start up the engine and ensure everything runs smoothly again!

Why Cub Cadet XT1 Mower’s Engine Overheats?

The Cub Cadet XT1 mower is a great machine with lots of features and the ability to mow large yards. However, it has some issues that can be frustrating. The most common problem with the Cub Cadet XT1 is overheating. This leads to other issues like smoke from the exhaust pipe and a loss of power.

Too Much Oil In Cranks

The engine overheats because there is too much oil in the crankcase. The oil that lubricates the engine also gets contaminated with debris from the air filter and dust from mowing. This causes an increase in engine temperature, which leads to overheating and loss of power.

How To Fix Problem?

To fix this problem, you will need to dispose of all old oil and add new oil (or change your oil filter). Then, start your mower and allow it to run for 15 minutes while it warms up. This allows any excess oil or debris from your old oil to drain out of your system. After 15 minutes, turn off your mower and check for leaks before restarting it again for another 15 minutes with no load on the engine (no blades turning).

After waiting another 15 minutes with no load on the engine, restart it again for about 10 minutes with no load on it. When you do this, check your engine oil level and top it off if it needs more than 1/2 quart of oil added.

If your Cub Cadet XT1 doesn’t start after doing these two things, your carburetor may need cleaning or replacing.

Mower Blades Don’t Rotate Or Are Broken

The Cub Cadet XT1 lawn mower uses a rear-wheel drive system. This means the engine is mounted under the deck in the center of the mower, and the wheels are attached to each side of the deck. The wheels are positioned at an angle so that the blades cut grass as you push or pull the mower forward.

The Mower blades do not rotate.

The mower blade clutch is stuck. The clutch is a device that disengages the blades from their drive shaft. A lever can disconnect it on top of the mower deck. If this does not solve your problem, check the belt that drives the blades and make sure it is tight. If the belt is loose, it will slip and not spin your blades when you engage them. Also, ensure no obstructions between the blade assembly and its drive shaft.

Blade clutch does not engage (stuck)

Blade clutch
If your mower’s blades are stuck because of rust or other debris, spray some penetrating oil on them and allow them to soak for about 10 minutes before trying to engage them again. Also, if you have an electric starter, try engaging the blades manually with this engine running. This may free up any debris blocking your blade clutch from engaging properly with its drive shaft. If neither of these methods works, you probably need to replace your blade clutch assembly altogether.

The blade drive belt is broken.
The blade drive shaft has come loose from its mounting bracket on the deck.
To fix this issue, you must ensure that both of these components are securely fastened back into place and test your mower again by starting it up. If everything still works properly, there is no need to repair anything else on your machine since only those two parts were causing your blades not to rotate properly.

How To Replace Cub Cadet XT1 Mower Blades?

If your Cub Cadet XT1 mower blades don’t rotate or have broken, you’ll need to replace them. You can order replacement blades from your local hardware store or online retailer.
If you want to replace yourself, follow these steps:
Step 1: Remove the Mower Deck
Remove all of the bolts holding down the mower deck. Lift on both sides of the deck and remove it from the machine. Set it aside for later use.
Step 2: Remove Blade Bolts
Using a wrench, loosen each blade bolt located by each wheel by turning counter-clockwise until they come out of their respective holes in the deck. Remove all four bolts before moving on to step three.
Step 3: Replace Blades
Replace all four bolts with new ones included with your new blades; tighten them by hand to ensure they are secure before proceeding with this task. Once they are tight enough, go ahead and finish tightening them all securely with a wrench before returning your mower deck to your machine.

Mower Deck Accumulates Grass

Mower Deck Accumulates Grass

This is a very common problem with this mower. It happens because the grass catcher needs to be bigger or the grass catcher bag is full.

The fix for this problem is simple: just empty the bag and increase the size of your grass catcher.

This can be done by going to your local hardware store and buying larger bags or by purchasing an attachment to increase the size of your current bag.

Another option would be to buy a second bag and use them at once. The drawback is that you will have twice as much grass to deal with at once, but it’s better than having clumps of grass stuck in your lawn every time you mow!

Why Is The hydrostatic Transmission System Not Working?

A pump and a circuit board control the hydrostatic transmission system. If broken, the circuit board needs to be replaced, but the pump can be replaced separately.

The hydrostatic transmission system on the Cub Cadet XT1 is a hydraulic system that uses oil to move the wheels in relation to each other. This differs from a traditional transmission, which uses gears and cogs to change gears.

When you engage the clutch on your Cub Cadet XT1, it sends oil through tubes that connect to the wheels of your lawn mower. The oil presses against one wheel and pushes it forward while at the same time pushing against another wheel and pulling it backwards. This allows you to move the wheels in any direction at any speed you want without using a gearshift or changing gears with cogs and gears.

How Does Hydrostatic Transmission System Work?

The transmission system uses the power from the engine to move all four wheels. You will lose control of your mower if something goes wrong with that system. The most common cause of this problem is that the belt has snapped or broken. Another possibility is that the drive pulley has broken off completely. You can fix this problem by replacing the belt and/or pulley on your mower’s transmission system.

If something goes wrong with your Cub Cadet XT1’s hydrostatic transmission system, you may notice that it doesn’t work properly or at all anymore. You might notice that one wheel doesn’t turn when you engage the clutch, turns too slowly when engaged in reverse gear, or both wheels spin at different speeds when engaged in forward or reverse gear modes. These symptoms indicate that something isn’t working properly within the transmission system.

The Most Common Causes Of Hydrostatic Transmission System Problems?

The most common cause of these problems is a worn out drive belt. If this happens, you can replace the belt by following these steps: 

  1. Park your tractor on level ground and set it, so it’s leaning backwards slightly on its rear wheels. This will allow for enough room for you to reach underneath the tractor and pull out the two drive belts from underneath its hoods.
  2. Remove both drive belts from their pulleys by sliding them off each pulley’s centre shafts with your hand until they come off completely from their respective pulleys’ ends (this should take about 10 seconds).
  3. Remove both drive belts from their pulleys’ centre shafts by sliding them off each pulley.
  4. Inspect all three belt pulleys for cracks or wear marks. If you find any of these problems, replace the damaged belt pulley with a new one.
  5. Clean both drive belts with a damp cloth or paper towel, then replace them on their respective centre shafts in their original locations.

Do Cub Cadet CT1 Have Excessive Vibrations During Operation?

One of the most common complaints about the XT1 is excessive vibrations during operation. Many owners have commented that they feel like they are riding a jackhammer when they cut their lawns. The vibrations are so bad that they make it difficult to cut the grass in certain areas because of their unevenness. This causes uneven cuts and poor performance from your mower.

Another problem is that the blades sometimes strike each other when you engage them for cutting. This can cause damage to your blades and even lead to them breaking off if you continue using the mower as it vibrates too much for safe operation.


We cover some of the most common problems owners of this model tend to experience and how to fix them. If you can’t find what you need here, we recommend checking out the manufacturer’s website directly or enlisting the help of a local dealer.
