4 Most Common Cub Cadet XT1 Problems And Quick Fixes

A mowing tractor is a practicable companion when mowing medium-sized lawns. Among the most reliable mowing tractors, you can lay your hands on is the Cub Cadet XT1 LT50, evident from its impressive specs. As with any garden utility, you must be ready for occasional malfunctions when using a Cub Cadet XT1. The most common Cub Cadet XT1 problems are starting issues, power loss, faulty tensioner pulleys, bad drive belts, and excess vibrations.

Read on as we detail these problems and practical solutions.

Cub Cadet XT1 Starting Problems

Nothing is as frustrating as trying to start your mower, but it is not responding. Cub Cadet XT1 starting problems appear to be frequent, judging by responses on multiple tractor forums.

Several things may cause starting issues, including insufficient or poor-quality fuel, a bad battery, low engine oil, a bad starter solenoid, and clogged fuel lines.


Start by checking if you have adequate fuel in the tank. It should be of high quality as per the manufacturer’s recommendations. In case of wrong or low-quality fuel, a fuel line flush will be necessary before you fill the tank with the right one.

A possible area that is easy to overlook is the fuel cap. If clogged, it can present starting issues, as it creates a vacuum in the fuel tank; thus, fuel doesn’t flow freely. Clean a clogged fuel cap for fuel flow and an easy start.

The next area of focus is the battery. Your mower may fail to start due to a dead battery. The solution is jumpstarting the battery or getting a replacement. Ensure the battery is in good shape by cleaning its terminals to eliminate sulfate buildup. 

Check the wires to be sure there is no problem with the connections. Fill engine oil and check for leaks to bid goodbye to mower starting difficulties.

Power Loss

You may experience Cub Cadet XT1 problems when working, where it suddenly loses power and dies. It may need a few hard starts before it revives, though it can shut down again. The hitch lies in the fuel or air systems, like a dirty carburetor, clogged or dirty cooling fins, blocked fuel lines, or a malfunctioning air filter.

How To Fix

You fix the problem by probing the fuel line and air system. You can start with the fuel line by checking the tank to see if you have enough fuel. Also, note that low-quality fuel can also be the culprit, so you need to go for the high-grade type for your mower’s best performance. Use a carb cleaner to unclog a blocked fuel line. 

Probe the cooling fins and clean them if dirty. Replace broken fins, or straighten them if possible. A dirty carburetor requires cleaning to allow for proper air and fuel mixture. Its parts should be okay; if not, make the necessary repairs and replacements.

Cub Cadet XT1 Transmission Problems

Most Cub Cadet mowers, including the XT1, use hydrostatic transmission. While this transmission is reliable for mowers, it is the source of various Cub Cadet XT1 problems. The common hiccups include a bad drive belt, low hydraulic fluid, and a faulty tensioner pulley.

Pointers of a bad transmission include grinding gears, wheels not moving, and sudden starts and stops during operation.


You troubleshoot Cub Cadet XT1 transmission problems by checking the hydraulic fluid levels. You should have enough transmission fluid. It should be the right one, as recommended by Cub Cadet. Please get rid of old hydraulic fluid, as it may be the root of the problem.

The solution for a bad drive belt is getting a new one. In the case of a faulty tensioner pulley, you should lubricate the tensioner arm or replace the pulley.

Excessive Vibration During Operation

Excessive vibrations are among the most common Cub Cadet XT1 LT50 problems. The shaking can sometimes be so intense that it affects steering. Possible causes of vibrations include:

  • Unbalanced or worn-out blades.
  • Improper deck height.
  • Low tire pressure.
  • Loose or missing engine assembly bolts.


Are the wheels in good shape? Inspect them to see if they have punctures or are worn out completely. It is easy to deal with punctures if you have a tire repair kit. You locate the puncture and patch it up. Replace a completely worn tire.

If the tires are fine, check the deck. Adjust its height to a reasonable level where it doesn’t touch the ground when mowing. Additionally, clean it to remove any debris that might contribute to the shaking.

Sharpening and balancing the blades is another answer to mower vibrations. After maintaining the cutters, you check the engine assembly to ensure all bolts are intact.

Final Thoughts

This piece looks at the frequent Cub Cadet XT1 problems and their fixes. As we can see, most issues are easy to sort, but it is better to avoid them by regularly maintaining the mower.

Inspect the mower routinely to determine if anything is amiss, and solve the hitch before it becomes severe. Meanwhile, ride the XT1 on your lawn and appreciate its efficiency.
