1. Engine Not Starting or Stalling

The engine stalling or not starting is common with the Cub Cadet XT1 LT50 model. 

Some reasons why your Cub Cadet mower may encounter this problem include inadequate gas in the system, defective spark plugs and frayed spark plug cables.

Some users have also complained that white smoke emanated from their engines after days of idling.

Causes

• Frayed spark plug cables and faulty spark plugs
• Inadequate/no gas in the system

Fix

• Check wires connection and replace spark plugs if you notice black carbon deposits on the electrode build-up.
• Drain stale gas from the fuel system and refill it with a fresh one.

2. Clogged Mower Deck

If excess grass is pushed through the Cub Cadet XT1’s mower deck, the lawn traction may get clogged. Several factors may cause blockage and clumping. This can be a result of age, the blade’s quality or how the mower is run.

Causes

• Warped blades
• Wet grass
• Dull or unbalanced blades

Fix

• Replace warped mower blades.
• Avoid mowing wet grass.
• Sharpen and balance your lawn tractor blades.

3. Overheated Engine and Exhaust Systems

This is also one of the common problems of the Cub Cadet XT1 lawn tractors. Some XT1 LT50 users have complained about overheated exhaust systems and engines.

In this case, the mower may only run for some hours before it will stall. You will also notice that the engine will run at a high temperature when you lift the hood.

Causes

• Using a wrong engine oil viscosity
• Dirty air intake screen
• Dirty cooling fins

Fix

• Use the correct engine oil for your lawn tractor.
• Clean dirty air intake screen
• Clean dirty cooling fins.

4. Uneven Cut

This is a common problem with the Cub Cadet XT1 Enduro Series lawn tractor. 

Your lawn tractor may cut unevenly as a result of worn mower blades, wrong rollers position, and low tire inflation, causing the mower to leave behind strips of uncut grass between the blades.

Causes

• Low tire inflation
• The deck is too low
• The gear is too fast
• Worn or bent mower blades

Fix

• Inflate the tire to the required tire pressure.
• Level the cutting deck.
• Select a recommended speed.
• Replace worn or bent blades with new ones.

5. The Battery Does Not Charge

If the battery of your lawn tractor does not hold a charge, you may need to check if there is a bad contact between the battery pole and the cable. 

This issue is familiar to the Cub Cadet XT1 LT42 lawn tractor.

Causes

• Battery cell fails
• Bad contact between the battery pole and cable

Fix

• Install a new battery
• Replace or clean the cable.

6. Deck Belt Popping Off

A deck belt that is popping off your tractor can be frustrating and annoying. This issue can be associated with worn or damaged brackets, faulty spindle housing, and interference of dirt with the deck belt tension.

This will hinder the performance of your XT1 lawn tractor.

Causes

• Worn or damaged brackets
• Faulty spindle housing

Fix

• Replace the worn or damaged brackets with new ones
• Replace defective spindle housings

7. Blades Won’t Engage

The blades of your Cub Cadet LT50 lawn tractor may get twisted, dinged up and dull after some time. In this case, the mowing machine may become less efficient over time due to this slow degradation.

Apart from the blades, you can also check components such as the PTO switch and PTO clutch to troubleshoot this problem.

Causes

• Faulty PTO switch
• Dysfunctional PTO clutch
• Faulty clutch solenoid
• Dull, twisted or dinged-up blades

Fix

• Change the faulty PTO switch
• Replace the faulty clutch solenoid.
• Replace the PTO clutch
• Sharpen dull blades or replace them if they are in a bad condition.

8. Vibration Issues

Vibration problems are also one of the problems that the Cub Cadet XT1 LT42 model may face. 

If you notice this, you need to check important components such as the drive belt, drive pulley, and deck blades to solve the problem

It is also possible that the mower can also vibrate excessively due to worn sheaves or belts.

Causes

• Dirty drive pulley
• Worn traction drive belt
• Deck blades are bent or unbalanced
• Worn sheaves or belt
• Debris in sheaves or on the cutting deck

Fix

• Replace the drive pulley when necessary.
• Check and change the worn traction drive belt with a new one.
