The John Deere 3025E (Economy) is a well-rounded and popular compact tractor great for use in heavier-duty projects on bigger spaces of land. This model will need maintenance and may require repairs over time due to frequent use. Most occurring problems are easy to fix on your own. 

Owners of the John Deere 3025E have experienced the following problems: 

  • Engine struggles to start
  • Engine stops during operation
  • Diminished engine power
  • Irregular fuel consumption
  • Abnormal engine noise
  • Transmission shifts hard
  • Steering issues
  • Front axle rattles
  • Differential lock assembly breaks down
  • Engine overheats
  • Exhaust spews smoke
  • Power take-off problems

This article will explore these problems and their fixes in more detail below. You will also learn why owners like this particular model of John Deere.

1. Engine Struggles To Start

An engine may have a hard start or not start at all due to a blockage, worn-out cylinder block, or excessive use. Your engine could also have issues with the fuel shut-off valve or clogged injectors.


To fix this you can refer to your user manual to find the parts on your tractor. 

Check that the battery and connections are charged and clean.

Look at the following and see if they are clogged and need cleaning, adjustment, or replacement:

  • Fuel filter and lines
  • Fuel shut-off valve
  • Fuel tank
  • Fuel injection pump
  • Sediment bowl
  • Cylinder block’s components
  • Starter
  • Piston rings
  • Head gasket

Additionally, make sure that there is no water or air in the fuel or lines, and that you have used the correct oils throughout the machine. 

If all of these are in good condition, and the engine still will not start, you will likely need a service professional to take a look.

2. Engine Stops During Operation

An engine that halts while using it is a frustrating experience, but can typically be resolved by looking over a few things related to the engine and fuel filter and lines.


  • Allow the engine to warm up. Do not turn it on and drive right away.
  • If the fuel filter or lines are dirty or clogged, clean or replace them. There should not be any water or air in the fuel lines. 
  • Make sure that the fuel clamps are tightened into place.
  • The engine will seize up if it has insufficient oil or the wrong oil type. Check this to see if you need more or different oil.
  • Make sure the exhaust pipe is not clogged, dirty, or broken. Replace if needed.
  • Charge the battery and do not let your tractor idle for long periods.
  • Make sure you have coolant in the system.

3. Diminished Engine Power

This economical tractor has a powerful engine for various jobs. However, it can lose its vigor after rigorous use. As a result, parts will become worn including the injectors, hoses and pipes, and filters. These worn parts can become faulty, use the wrong pressures, become blocked or jammed, and possibly overheat or diminish the tractor’s engine.


  • Check each system that affects the engine for worn parts that need cleaning or replacing.
  • Change clogged and dirty fuel injectors. Check the setting so that the fuel pressure is correct.
  • Fuel hoses and fuel and air filters must be clean for the engine to work at full power.
  • Check the governor spring. If it is deformed it will result in a low engine rpm. Replace or adjust this.
  • Make sure that the low idle setting is adjusted and balanced for operation.
  • Do not overload the tractor according to its maximum capacity. If you do, the engine will struggle to retain its power and do the job. Straining your engine could result in greater repairs and costs.

4. Irregular Fuel Consumption

The John Deere 3025E tends to use more fuel over time than other models. In most cases, this is due to a dirty carburetor, faulty cylinder liners, or an oil leak in the tank or connecting hoses.


  • Check the fuel tank and hoses to see if there are any leaks. Replace them if necessary.
  • If the cylinder liners are faulty, replace them and ensure that the cylinder is aligned properly.
  • Make sure you use the correct fuel according to your user’s manual.
  • Locate the piston ring and tighten it. If it is deteriorating, it will need replacement.

5. Abnormal Engine Noise

If the engine sounds like it is knocking, it can be caused by irregularities with the fuel injection pump, unclean fuel nozzles, a worn crankshaft or governor spring, or low levels of oil.


  • Fill up the oil to the correct level with the proper kind. 
  • Consider if the crankshaft or governor spring needs to be replaced.
  • Ensure that the fuel nozzle and pump are clean and aligned. Make sure the fuel pump timing is correct and adjust if not.
  • Allow the engine to warm up before driving the tractor.
  • Use the correct fuel grade.

6. Transmission Shifts Hard

If the transmission is shifting hard, especially in reverse, you likely don’t have enough lubricant or fluids to properly operate it.


Check the transmission fluid level. If it is low, simply filling it up may not be the only fix. You have to make sure there are no other reasons for its low level.

Aged transmission fluid will lose frictional properties leading to poor shifting and gear movement. If it smells burnt or looks dirty, that is an indication to drain and completely replace it. If you do not replace it right away, your transmission will endure greater and more costly damage.

Use high-quality synthetic transmission fluid designed for use in a tractor for optimal shifting. Synthetic fluids do not contain waxes, meaning that they will not flow as slowly in cold conditions. Keeping the moving parts lubricated well will extend the life of the transmission.

7. Steering Issues

Similar to the John Deere 1025R, if the steering wheel is loose or moving too easily, fill up the hydraulic oil. Look over the steering cylinder and repair or replace it.  

If you frequently use a loader, this added weight can strain the moving parts, including the steering. Jack up the front of the tractor and check the front axle and bushings for signs of wear and tear. If this is the case, replace the parts, including the pin holding them together. Tighten any connecting bolts. 

If the steering is difficult to move, first check the oil and top it off if needed. Then, check the tire alignment, hydraulic connections, steering pump, and power steering. If there are signs of wear and tear, replace or adjust as needed.

If the steering completely stops working, the hydraulic system is to blame. There may be air in it, a low level of hydraulic oil, or the hydraulic steering cylinder is broken. You will need to remedy or replace parts to get the steering working again.

8. Front Axle Rattles

When driving the John Deere 3025E the front axle may rattle. This can cause the steering or overall operation to be uncomfortable. The teeth of the gears may have broken. You will need to replace the gear(s). Check the ball bearings and see if those need replacement as well.

9. Differential Lock Assembly Breaks Down

Differential locks connect axles to transfer torque to the wheels for traction. If this breaks down, the wheels may spin at different rates (especially when turning) or show signs of uneven wear.

Evaluate the system and look for worn or loose carrier bearings, joints, discs, clutches, and gears. Tighten and replace as needed. 

If the tires are unevenly worn, they should be replaced to reduce further strain on other parts of your tractor.

10. Engine Overheats

Like the John Deere 2025R, if your engine is overheating, refill the coolant to optimal levels and clean the radiator fins. Make sure that the belt is tightened at the proper tension.

Make sure the tractor can handle the load and reduce it if necessary. The John Deere 3025E has a lift capacity of up to 1,356 pounds (615.1 kg). Also, if you are cutting brush that is too high for the machine, you may overwork the engine.

11. Exhaust Spews Smoke

If the exhaust system is spewing smoke, turn off the tractor immediately. Make sure you have used the correct oils throughout the entire system, and that they are filled up. 

Piston rings may also need to be replaced if you see smoke. If the smoke continues after trying these, you will need to contact a professional for service on the tractor.

12. Power Take-Off (PTO) Problems

PTO problems generally occur if the tractor is overloaded or cutting brush that is too high or too thick. You will notice that you may not have enough horsepower to complete the job.

Make sure your engine and transmission are functioning well and have the correct kind and levels of oil. Ensure that the PTO shaft is intact and properly aligned. Otherwise, you may need a different tractor for the kind of project you are trying to do. 

Don’t let the grass get too tall, and reduce the load to allow the PTO to work as it was designed to do for this smaller-sized tractor.
