7 John Deere 3025e Problems and Possible Fixes

1. Engine problems

The engine is the most important part of a tractor. When it develops a problem, the tractor won’t start or move. In some cases, it may stop mid-stream tasks.

Thus, keeping the engine in an apt condition is the only way to ensure you get the best service from the tractor.

Note that the engine will always be the first to check when your lawn tractor refuses to start. Firstly, the engine may refuse to start due to fuel delivery or spark plug issue.

Secondly, you may find it hard to keep the engine running if there are problems with the carburetor. Also, the engine may refuse to idle when the gap between the spark plug is inappropriate.

Finally, the engine will run rough if there are loose screws in the muffle or clamps. Whatever engine-related problem the lawn mower has, you must find an appropriate fix.


  • Review John Deere diagnostic codes
  • Check the fuel delivery system or the spark plug.
  • Adjust the choke plate to stop air from getting into the carburetor’s combustion chamber.
  • If the engine can’t idle, check if the spark plug is ok.
  • Tighten the screws on the muffle.
  • Check the gas cap and ensure you tighten it.
  • Sharpen the blades to enhance performance and enable the engine to be more efficient.
  • Clean the clogged or dirty carburetor.

2. Rust-related damages

When the fuel tank rusts, it causes the build-up of debris and sediment around the fuel shut-off valve.

So when they accumulate and become too much, they make it hard for fuel to flow freely to the combustion chamber.

Ensure to use fuel additives compatible with ethanol-blended fuel before you store the tractor. It could save you from more trouble.

Other than the debris, rust can also affect many other parts of the tractor. Specifically, rust can impact the deck.

This is likely to happen if you have the habit of mowing wet grass. If the rust is not attended to immediately, it can become widespread and render the mower useless.

Even so, the mower may continue giving you service, albeit posing a safety issue. So ensure to fix the problem as soon as it becomes apparent.


  • Open the gas cap and turn on the tractor while the throttle is engaged. This will force out any rust formation.
  • Use fuel additives to neutralize rust if you use ethanol-blended gas.
  • Unfortunately, you may not repair the deck when it rusts. You must visit a dealer to replace it.
  • Clean fuel filters.
  • Clean the dirty fuel nozzles.

3. Tractor refuses to move

If you turn on the engine, but the tractor does not move, the throttle lever may be wrongly set. Also, the tractor may refuse to move if the blades are not sharp or the ground is not even.

The uneven ground makes the tractor lean on one side. Additionally, the tractor may refuse to move when the drive belt cannot transfer the engine power to the wheels.

Thus, the engine may run, but the wheels cannot move if the belt is broken. The mower will not move when the pressure switch is faulty.

Also, if the switch is starved of oil, there will be no pressure in the system. A faulty switch will thus prevent the mower from moving forward or backward.

Besides a defective switch, when the tensioner pulley has an issue, it may not transfer the power to the wheels.

This will compromise the ability of the mower to move and could make it hard for the mower to work efficiently.

Lastly, if the axle key shears off, it may not continue holding the wheel on the axle. As a result, the mower will not move forward since no engine power is transferred onto the wheels.

  • Set the throttle lever and turn the tractor on with no throttle engaged. It forces the rust out.
  • Remove the blade cover and sharpen the blades.
  • Replace the broken belt.
  • Replace the pressure switch.
  • Get a mechanic to replace the axle key.

 4. The tractor cuts the grass unevenly

The tractor may cut unevenly when the blades are dull or not correctly positioned. Similarly, the mower could cut the grass unevenly due to a bent crankshaft, damaged wheels, and cutting deck.

When the wheels are set at different heights, the mower may cut the grass unevenly. This happens even if the wheel is a notch above or below the other.

But if the height is ok, check for damaged wheels. Damaged wheels may make the mower harder to drive since the deck may dip on one side.


  • Sharpen the blades.
  • Adjust the position of the blades to ensure that they cut the grass evenly.
  • Inspect the four wheels and ensure they are at the same height. If not, adjust them and consider replacing them if damaged.

5. The lights do not work

If you work in a commercial place, you may only be allowed to work at night. It means that your tractor headlight should be working.

Unfortunately, the headlight may refuse to work at night. In most cases, the lights will flicker when you turn them on.

The light problem needs to be sorted out as fast as possible to allow you to continue working.


  • Check the lighting circuit. If the wires are charred or nipped, you may need to replace them.
  • Replace the headlights.

6. The battery does not charge

If the battery refuses to charge, starting the tractor could be a big problem. So you may not mow the grass as planned.

If you can identify where the problem is and fix it, you will be able to operate the tractor smoothly.


  • Ensure you tighten the battery terminals.
  • Clean the battery terminals.
  • Replace the battery.

7. The tractor vibrates excessively

After some hours of mowing, you will discover that the tractor vibrates so much. This could make the operator feel uncomfortable.

The mower will vibrate if the blades are damaged, improperly sharpened, or out of balance. It may also vibrate due to worn-out engine bolts.

Similarly, the tractor may vibrate due to failed bearing in the clutch. Whatever the case, you should find an appropriate solution to the problem.


  • Inflate the tires.
  • Sharpen and balance the mower blades.
  • Remove any foreign item that may wrap itself around the blade when mowing.
  • Replace the damaged bearings.

John Deere 3025e Review

John Deere 305e was designed for anyone interested in working on small parcels of land. The tractor is comfortable and easy to use.

Besides, it runs quietly if it is in tip-top condition and could allow you to work for many hours. Also, the tractor can lift more than 1,200 pounds and consumes very little fuel.

Unfortunately, the tractor features too many plastics. So it may hold poorly compared to those fitted with metals.

The plastic parts break up easily, meaning you will incur more expenses replacing them. Furthermore, the lights are mounted on the outside and so they break easily if you don’t install a cage.
