Furthermore, you may experience signs such as leaking fluid, frequent slipping of gears, and clunking noise. In addition, the lawn tractor will turn slower than usual.

Causes

2. John Deere X354 Steering Problems

Your John Deere X354 lawn tractor may become difficult to steer over time. The likely causes of this issue are worn bushings or loose bolts, preventing proper gear engagement.

3. John Deere X354 Mower Deck Problems

A faulty cutting deck can cause the lawn tractor to vibrate excessively, mow unevenly and scalp your grass. Here is an overview of mower deck problems:

Uneven Cut

The mower deck is capable of making the grass blades stand while they can be mowed evenly. 

If your John Deere deck is faulty or it hasn’t been cleaned for a long time, the grass buildup may prevent your mower from cutting your lawn evenly.

Causes

• Dull or bent blades.
• The brake or clutch isn’t properly adjusted.

Fix

• Inflate the tractor tires evenly.
• Change the blades when necessary.
• Adjust the brake or clutch as needed.

Clogged Discharge Chute

If the underside of your mower deck is dirty with debris and lawn clippings, your cutting deck can get blocked and this will cause inadequate airflow to discharge lawn clippings. 

Causes

• Low engine speeds
• Wet grass
• Travel speed is too fast

Fix

• Open the throttle fully.
• Avoid mowing wet grass to prevent it from clogging your mower deck.
• It is advisable to reduce the speed.
