John Deere x320 Problems

1. Carburetor Problems

The carburetor provides the chamber in which the fuel and air burn. Thus, the John Deere x320 carburetor design utilizes the latest fuel injection technology.

The technology allows it to be more efficient in burning fuel and releases fewer environmental pollutants. But sometimes, the carburetor develops problems and could make mowing a nightmare.

So, when you notice the engine start hunting for power at high speed or in idle mode, it is a tell-tale sign that the carburetor is problematic.

In some cases, the engine may fail to start from idle. This happens when the carburetor does not output enough power.


  • Check for oil leaks in the carburetor and seal them.
  • Check the mixture adjustment and idle screws. If they are damaged or there is a crack, you may need to tighten or replace them.
  • Adjust the control cable to help control the carburetor.
  • Remove all non-metallic parts and clean the carburetor.
  • Check fuel delivery.

2. Low Rpm Problem

Sometimes the motor revs up, but you will feel it is weak. This could happen when the RPM experiences problems at Wide Open Throttle (WTO).

The problem may be bad fuel, defective coil, worn-out fuel filters, and plugs. The low Rpm problem may be mild and still allow you to use the tractor to perform unhindered tasks.

However, the issue must be fixed before the tractor’s performance deteriorates.


  • Check if the coil has enough power and can produce enough energy to withstand a hot and weak spark. If it cannot, replace it.
  • Check the oil level and change it.
  • Clean the air filters and fuel filters.
  • Apply grease and orient the fuel filters to see if you get the best results.
  • If you do all these things, but the error persists, you may need to visit your dealership.

3. No Sparks On Both Plugs

The tractor plugs could refuse to produce sparks, making it difficult for the engine to start. Typically, the engine absorbs the plug spark heat before it swings into action.

Thus, if the plugs do not produce the sparks, the engine may not start. This could happen if the socket is faulty or if there is an unresponsive control module.


  • Test the control module to determine why the plug is not producing the sparks.
  • Replace the tractor’s control module.

4. John Deere X320 Transmission Problems

After extended use on gardening and lifting tasks, the transmission pump seal may wear out. If allowed to go on for long, the transmission may lose its power.

Also, if the belt has an issue, it is likely to make the transmission lose its power. When it happens, the engine fails to turn if the straps and the pulleys are misplaced.

Similarly, if the drive pulley is stripped out of position, the transmission may need to be fixed. In some cases, the tractor may only move forward or backward.

This tells you that the reverse paddles may need more pressure. So the paddle finds it challenging to engage the wheels.


  • Check if your tractor’s seals are worn out and replace them accordingly.
  • Place back the misplaced belt on its path.
  • Clean out the accumulated debris in the transmission tunnel.
  • Drain the old oil and replace it with the new one.
  • Remove excess oil.
  • If the drive pulley is soft, replace it.
  • Lubricate and apply transmission oil, if applicable, to your pulley.

5. Steering Problems

The steering is an essential part of the tractor. It determines the direction in which you move the tractor. When the tractor is still new, the steering will work well.

But over time, it may start experiencing problems. Hitting a rock at high speed or wear and tear may damage the steering wheel bearings.

Also, the steering is likely to lose calibration over extended use. So it is vital that the problem gets fixed before it results in an accident.


  • Realign the steering wheel
  • If the ball joint is loose, tighten the nut that holds it in place.

6. Fuel Pump Troubles

The fuel pump may refuse to work if it is cracked or the outer metal surface is damaged. If the fuel pump and filter are dirty, you will likely experience fuel pump issues.

A dirty air filter can also lead to pump issues. On rare occasions, the fuel valve may remain open or closed. This could also lead to pump issues, so you must fix it as soon as possible.


  • Close the fuel valve.
  • Remove the mounting screws, disconnect the hoses and remove the broken parts.
  • Replace the damaged parts with new ones.

7. Starting Problems

When the mower refuses to start, the first person you will think about is your mechanic.

However, this need not be the case always because sometimes you can fix the cause of the problem on your own.

A dirty fuel filter or air filter could cause the starting problem. Furthermore, a dead battery, faulty ignition, or loose contacts may cause the problem.


  • Replace the spark plugs
  • Replace oil filters and air cleaner
  • Recharge the battery
  • Replace the battery
  • Check the ignition coil air gap

When the drive belt cannot turn the trans or input drive shaft, the traction drive belt could have an issue. Also, a loose belt may make it difficult for the trans and the input drive shaft to turn.


  • Replace the belt
