1. John Deere X324 Won’t Start

The most common John Deere X324 problem is difficulty starting the engine. Starting difficulties might appear as a failure to start, a difficult start, or a hard and slow start.

Older John Deere mowers that have been actively used for several years tend to have more difficulty starting their engines.


  • Spark plug malfunction
  • Wrong carburetor adjustment
  • Clogged fuel lines/fuel filter
  • Stale fuel
  • Starter problems or damaged electrical wiring
  • Low battery voltage


Check the spark plug for burnt ends, broken surfaces, or carbon buildup. If dirty or damaged, clean the spark plug or replace it.

If the fuel is stale or has left behind sticky or slimy residue in the fuel tank, drain it out, clean it, and refill the tank.

After that, replace the fuel filter if it is clogged and clean the fuel lines using a carburetor cleaner to clear any obstructions.

The carburetor may be adjusted too leanly, letting only a tiny amount of fuel into the engine, if the engine starts and stops abruptly. Set the carburetor mix and idle screws so that there is enough fuel flow.

Additionally, make sure the carburetor is clean and, if it isn’t, apply a carb cleaner to clean the jets and bowl.

Finally, if your mower isn’t starting, the issue could be a faulty starter or low battery. If the starter is damaged, repair/replace it.

Charge the battery if it is producing less than 12 volts. If it refuses to charge, battery cells may be dead and you may need to replace the battery.

2. John Deere X324 Steering Problems

Your John Deere lawn tractor may become difficult to steer over time. This could be the result of a loose bolt or worn bushings, which prevents the gear engagement necessary for easy steering. 

Whether your steering is too loose or too tight, it can be corrected by locating the source of the problem and replacing the necessary components.


  • Loose bolts or screws 
  • Worn bushing
  • Worn steering sector gear
  • Damaged pinion gear


The bushing holds the pinion gear in place. The pinion gear begins to experience friction when the bushing gets worn out.

The pinion gear at the end of the steering wheel shaft is synchronized with the steering sector gear. By moving the steering wheel, the sector gear allows you to rotate the wheels from left to right.

If the sector gear or pinion gear gets damaged, it results in steering problems. Identify and replace the damaged parts to fix your steering problem.

3. John Deere X324 Transmission Problems

The John Deere X324 uses a sealed hydrostatic transmission system that facilitates its forward and reverse movements.

You may have a problem with your transmission system if you experience difficulty moving the tractor forward or backward. The engine running and the tractor refusing to move is also an indication of transmission problems.


  • Insufficient transmission oil
  • Worn out pump seals 
  • Aeration/cavitation
  • Glazed/misplaced belt
  • Damaged pulley
  • Disengaged hydrostatic lever


Examine the fluid level. If the fluid level is too low, do not top it up yourself as the transmission is sealed. Contact your John Deere dealer for fluid replacement.

If the fluid level is continuously low, look for and repair any leaks in the transmission system.

Purge the hydraulic system if there is any air pollution or leakage. After that, check the belt and pulley system for damage and tighten or replace the belt as needed.

If the piston pump seals are worn or damaged, they should be replaced. This would help to prevent abrupt power outages in your mower.

Also, ensure that the hydrostatic lever is properly engaged to the transmission system and hydro pump to facilitate movement.

4. John Deere X324 Mower Problems

Mowing issues are fairly typical in John Deere mowers and can happen in many ways.

Your John Deere may be cutting unevenly, skipping random lawn patches, or the blades may not be cutting grass effectively.


  • Cutting deck obstruction
  • Low cutting deck height
  • The mower blade is bent or blunt
  • Slack or damaged belt
  • Dirty pulley
  • Fast ground speeds


Cleaning the mower deck to remove obstructions should be done first. Using a water hose, scraper, or pulley knife, remove caked-on grass and debris.

Then, if the cutting height deck is too low, especially if your grass is thick and tall, adjust it. Are the blades bent? Is it dull or out of balance? If so, adjust, sharpen, or replace the blade.

Mowing issues can also be caused by a faulty belt and pulley system. If the belt is loose or glazed, it should be replaced.

Inspect the pulley and idler springs, clean them, and replace any damaged parts.

Cutting grass at fast speeds might result in uneven cuttings and other mowing issues. When mowing, use slower speeds.

5. John Deere X324 Engine Surge

In certain circumstances, the John Deere X324 starts perfectly, but then the engine begins to surge and perform poorly.

Slow acceleration, rattling noises while mowing, rough running, excessive engine vibration, a surging mower, engine running only on choke, and other symptoms may indicate a badly running engine.


  • Stale or old fuel
  • Clogged fuel filter/fuel lines
  • Stale engine oil
  • Dirty air filter
  • Worn out spark plug
  • Carburetor problems
  • Worn drive belts
  • Clogged mower deck  


A clogged fuel filter or old, unclean gasoline may be the cause of poor engine performance. Avoid using gasoline with alcohol additives, for smooth engine running.

After 50 hours of use, you should change your oil at least once a season to avoid having an engine that runs poorly due to unclean oil. Don’t forget to clean or replace the air filter when you’re changing the oil.

If your John Deere is having trouble starting, it may also be time to change the spark plugs.

Next, look for blocked jets and bowls in the carburetor. To clean the carburetor, use a carburetor cleaner, or use a carburetor repair kit to rebuild it.

It’s usually time to replace the drive belts if the tractor surges or vibrates severely even after you’ve tightened all the loose nuts. Another indication of a worn belt is slow acceleration.

Lastly, unclog the mower deck. To prevent engine running issues, it is a good idea to frequently lift the tractor and remove any sticks or weeds that are clogging the pulleys and belts.

6. John Deere X324 Electrical Problems

Electrical issues in your John Deere X324 could appear as a faulty starter, defective lights, a dead battery, or a battery that won’t charge.


  • Blown fuse
  • Low battery voltage
  • Poor terminal connection
  • A faulty starter
  • Wiring damage
  • Dead battery cells
  • Damaged light connections


A faulty starter and improper wiring will cause the engine to refuse to start. If the wiring is faulty, it should be repaired or replaced.

Examine the fuse and replace it if it is blown. Then, using a multimeter, determine the voltage of the battery. It is low if it is less than 12 volts and should be charged.

If the battery won’t charge, the terminals and wires may be dirty. Clean them and tighten all connections. If this does not work, some of the battery cells may be broken, and you will need to replace the battery.

Check for short circuits and a damaged light connector if you have faulty lights. After that, replace the light bulb.
