As indicated, faulty fuel system is the primary reason behind the problem related to the engine. 

Problem 1: Engine Does Not Start 

One of the most common problems that you will face is your diesel does not crank over.

It could be due to using the wrong type of fuel or a bad fuel system. What do I mean by a bad fuel system? It means a clogged fuel filter, a blocked nozzle.

But most importantly, a damaged fuel injector is one of the key reasons for your engine not starting.

Solution 1: Replace Fuel Injection Pump

It is best to replace the pump rather than repair it. Whenever a fuel injection pump is damaged, there is no scope for repair.

Although technically you can replace the fuel injection pump by yourself we do not recommend you to try it unless experienced. Therefore, consult an expert on this one.

Solution 2: Replace the Fuel Filter

Step 1: Remove the bracket from the fuel filter using a screwdriver.

Step 2: Take the fuel filter off.

Step 3: Put another fuel filter in the place.

Step 4: Tighten the nut and bolt.

Solution 3: Use the Correct Type of Fuel

For diesel engines like the one used in tractors, use 15W-40 or anything with 20W grade. This is because for heavy machinery activity more viscous fluid is desired.

Problem 2: Engine Takes Time to Start

Another issue related to engines is that it is either hard to start or it takes a lot of time.  

It happens when your fuel pump is dirty, fuel filter is clogged and piston rings are deformed. However, a bad injection nozzle can also delay the engine starting time. 

Solution 1: Replace Fuel Injector

Step 1: Pop the hood and locate all the lines.

Step 2: Remove all the return lines using wrench on top of the injector.

Step 3: Take the injector out.

Step 4: Use a wrench to remove the tap off the injector.

Step 5: Remove the washer from the tap and put it in the injector.

Step 6: Put the new rubber washer over the tap.

Step 7: Put the tap on the new injector.

Step 8: Fix the injector back to its position.

Step 9: Connect all the fuel lines to the injector.

Problem 3: Engine Knocking

Unfortunately, even tractors are not immune from the problems of engine knocking. 

If the coolant temperature drops, and the oil pressure is low then the engine will be prone to knocking. But faulty fuel injectors can also lead to this problem. 

Solution 1: Replace Fuel Injector

If the fuel is not atomized and sprayed properly then it won’t be enough for complete reaction. It is a problem because incomplete combustion leads to higher pressure. It leads to knocking.

Solution 2: Add More Oil

The typical oil capacity for John Deere 5425 is 9 qts. Keep the oil capacity within that range while you are using your tractor.

Problem 4: Engine Overheating

A tractor’s diesel engine is also susceptible to overheating. It happens for reasons like insufficient coolant, damaged cooling system, and radiator fins.

Solution 1: Fixing Leaked Coolant

This is the primary cause of engine overheating. Whenever there is a lack of coolant, the engine’s cylinder head expands and becomes more heated.  One of the consequences of this failed gasket.

Solution 2: Use More Coolant

Remove the radiator cap and check the level of coolant. If the portion is not adequate, then add more coolant.

Solution 3: Clean Radiator Fins

All you need to do is brush over it. You can also spray water straight through the radiator fins instead of sideways. 

Problem 5: Engine Loses Power

The engine loses power due to a problematic fuel filter, faulty injection nozzle, and non-synchronized fuel injection timing.

John Deere 5425 Transmission Problems

Problems  Reasons  Solutions
PTO keeps shutting off Faulty connection

Problem with PTO clutch lever

Fix the electrical connection.
Front Axle Howling Constantly Worn out bearings Change bearings.

Problem 1: PTO Keeps Shutting Off

PTO is key to transmitting energy from the power source to different components. But it is not immune from problems shutting off. 

It happens due to problems like faulty connection in the actuator and clutch lever. 

Solution:

It happens when the clutch does not engage as expected with the PTO. The primary reason is any fault with the wiring or the device not being charged enough.

To fix this, check the voltage through a voltmeter and make sure that it reads above 12.50. If it doesn’t then charge it.

If it still does not recover then change the wiring.

Problem 2: Front Axle Howling Constantly

It indicates the howling-type noises from the front axle of the tractor. It can happen due to defective bearings.

Solution:

The solution is to change the bearing. Unfortunately, this is not DIY work. It is hard to fix it by yourself unless you have experience in such crafts. It is better to consult professionals for this.

However, you can prevent it by using the proper grade of fuel and lubrication.

John Deere 5425 Steering Problems

Problems  Reasons Solutions

Problem 1: Steering Wheel Won’t Move

If the steering wheel stops working it is because of problems like minimum oil rating, or uneven tire pressure. Leakage in the hydraulic system can also lead to steering wheel problems. 

Solution 1: Adjust the Tire Pressure

Typically, the tire pressure should be around 35 psi. After determining the correct pressure, adjust the pressure using the right devices.

Solution 2: Fix the Leak

The hydraulic leak is one of the key reasons for problems in the steering system. It can be solved by sealing off the source of the leak.

You can add temporary fixes through commercial sealing products. But it is better to seek professional help.

Problem 2: Loose Steering Wheel

Sometimes your steering wheel might be too easy to move or it is loose. It happens due to minimum oil rating, and defective power steering pump.

Solution 1: Repair the Power Steering System

The repairing procedure involves changing the power steering pump, removing air from the steering system, and fixing the source of the leak.

Solution 2: Replace the Seal

Finally, you can tighten the steering wheel through replacing the seal in the steering system.

Repair the axle.

Increased Vibration Transmission based Problem

Worn out bearing

Replace the bearing.
RPM does not change with gauge Damaged wire at the alternators Fix the wiring.
FEL does not lift properly Defective connection to the control valve Adjust the connection to the control valve.

Problem 1: Tractor Does Not Move

Contrary to what you may think, it is not just because of the engine. It could be due to problems in the gear and axle. Your tractor will not move if the clutch malfunctions. 

Solution 1: Change the Clutch

The problem with the clutch will disable it to shift to different gears properly. Therefore, the first step will be to replace the clutch.

Solution 2: Repair the Axle

One of the key reasons for the tractor not moving is a broken axle. It can be solved by consulting a professional to repair the axle.

Problem 2: Increased Vibration

Vibration is another problem of this tractor. It is extremely uncomfortable for you as a user.

Solution:

Here, worn-out bearing is one of the reasons behind increased vibration. It can be solved by replacing the bearing.

It is recommended to seek help from professionals for this due to the complicated nature of the process.

Problem 3: RPM Does Not Change with Gauge

If the tractor’s tachometer does not relate to the actual RPM, it is due to damaged wire at the alternators.

Solution:

It can be solved by fixing the wiring of the tachometer. 

Problem 4: FEL Does Not Lift Properly

A defective connection to the control valve can make it harder for the Front End Loader (FEL) to lift properly. 

Solution:

The control valve helps to determine how the FEL will react to the commands. If there is any problem with the wiring or cable connection to this valve then it will not act properly.

So, replacing this cable will solve the problem.
