John Deere x320 Carburetor Problems

In cars, carburetor problems are generally caused by old or lousy fuel. As old energies are known to degrade and leave a grumpy residue inside the carburetor, they can create restrictions and prevent the proper flow of air and energy ratio from entering the engine cylinder. This is why you can refer to the mower’s dirty carburetor. There can be many symptoms of carburetor problems such as


  • Your John Deere X320 consumes extra fuel while operating a regular lawn and mode.
  • Due to the rough engine, smoke is coming out of your John Deere X320 muffler.

John Deere x320 Fuel Pump Problems

With age, any mower can have fuel pump problems. Fortunately with cars, you are getting sensors that will help you regulate proper fuel flow into the carburetor. But, if the sensor stops working, the pump will fail to supply enough fuel to the engine.

Thereafter, the mower’s engine is likely to backfire and shut off anytime. Condition: you should replace it first. To replace it, avoid using any electronic gadget.

Contact your authorized technician or nearby mechanic if you need to gain experience fixing technical issues with mowers. Below are a few steps to check and fix fundamental carbonator problems.

  1. Firstly remove the fuel cap to drain the fuel. It is recommended to put a fuel-catching container under the tank. 
  2. Now, unscrew the host and nut of the fuel line that must be located at the base of your John Deere X320’s fuel tank. 
  3. Once draining is done, remove any sediment or fuel residue using an extraction pump that has settled at the base of your John Deere X320 tank.
  4. If the debris is very sticky, don’t mind using air compression to blow it out there. 
  5. Remove all the fuel line that is situated before your injection pump and insert an air compression nozzle in the hose. 
  6. Blowing the air back toward the fuel line and removing the debris to replace and secure it is better. 
  7. Screw all the nuts and hose back. 
  8. Drain all water separators and replace the fuel filter as soon as possible.
  9. Now your tank is ready to be filled with fresh, high-grade diesel fuel. 
  10. Also, never mind replacing the fuel cap before starting your John Deere X320 engine.

Most of the hydrostatic problems in John Deere X320 Mowers are caused due to insufficient oil. Therefore, check the oil reservoir and fill it as necessary. Other than this, you should look at the faulty mechanical parts and replace them one by one with a new ones.

Hydrostatic problems may also arise due to overheating systems. Therefore you should always take preventive measures. If there is any leakage, sort it out as soon as possible.

While driving a John Deere X320, the most common issue you are likely to experience is low-power steering fluid. Make sure to keep your John Deere X320 steering fuel top-up once in a while to ensure its hydraulic power steering system functions properly.

With age, any mower can become challenging to steer. Sometimes, loose bolts can be as simple as a loose bolt that needs to be tightened up or replaced. Other than this, bushings that have been worn out may prevent proper gear engagement that is required for easy steering.

If you identify the problem area and replace the right part, you can quickly fix any steering that is too loose or too tight for your John Deere X320. Sometimes, you need to replace the bushings, and the problem is gone.

Other than this, air may also need to be replaced, but only if it has wear and tear. Make sure to leave it unattended, as it can hinder other components, and you might have to replace the whole sector plate, which will be very expensive.

John Deere X320 Transmission Problems

If there is any failure or damage to mechanical components, hydrostatic transmission problems may arise. It is essential first to check the operator’s manual that covers oil viscosity. If you have used old or overused fluids, it might be the culprit of hydrostatic problems.

Firstly, you should check for signs of liquid damage or leakage. Maybe, you need to replace the steering and fluids. However, the most common issue will be the oil itself. Here’s a step-by-step solution for this issue.

  1. Firstly get your John Deere X320 on level ground and set its parking brake. 
  2. Ensure the real is on the jack stand and all reservoirs are correctly filled. 
  3. Now you need to disengage the transmission and then start the engine. Check the operator manual to learn how to clear the message. 
  4. It would help if you moved the throttle control to a slow position when the engine runs while positioning the motion control lever in neutral. The brake pedals should be disengaged. 
  5. Now, you need to push the motion control lever forward and hold it for a few seconds. 
  6. Count to 5, pull the control lever back to the full reverse position and then hold it again. 
  7. Repeat this step 7-8 times to purge any air from the hydraulic transmission system. 
  8. You can neutralize the control lever and shut off your John Deere X320’s engine. 
  9. After setting the parking brake, top it off and check the oil. You need to disengage the brakes, remove from Jack stand and start the engine while engaging the transmission. 
  10. Now you need to move the control level forward to roll about 5 feet, slowly reverse to about 5 feet, and then return the lever to neutral. Also, switch to about 5 feet and then return the lever to neutral. 
  11. This process should be done at least three times before you start riding your John Deere X320.

After draining dirty fluid, refill the reservoir with a fresh high-grade fluid according to the manufacturer’s specs. If this doesn’t resolve the issue, you must replace the worn-out clutch discs.

John Deere x320 Deck Adjustment Nut Problem

If there is any deck adjustment or problem with your John Deere X320, your mower may end up scalping grass on your yard’s uneven areas or spots. I suggest you sit at the bottom of the wheel at least 1/8-1/2 of an inch from the ground. If you face problems adjusting the mower level, consider loosening the deck knot. If the nut is the problem, never mind replacing it.

  • Loosen the rear nut equally on each side of the John Deere X320 Mowers front lift rod.
  • Make sure to turn the front nut equally on each side clockwise. It will raise the front of your mower. 
  • On the other hand, turn the front nut equally on each side counterclockwise to lower the front of your John Deere X320 until the gauge slips in the adjustment point. 
  • As soon as the adjustment is made, tighten the rear nuts. 
  • If the nut is loose, always replace it first to prevent hindering the mechanical parts.
