1. Engine Starting Issues

Starting issues are probably the most frequent problem you can run into. 

Engine starting issues are quite common with the John Deere 1024r. The tractor may be difficult to start or cannot be started at all.


  • The gearshift lever was positioned wrongly
  • Worn spark plug
  • Stale fuel
  • Old oil
  • Dead battery


The gearshift lever is frequently misaligned or placed in the neutral position. To solve this problem quickly, make sure the lever is always in the high or low range before starting the tractor.

If that isn’t the cause, examine the spark plug and replace it if it is worn out or damaged.

If the fuel is stale or has left a sticky or slimy residue in the tank, drain it, clean the tank, and refill it. After that, replace the fuel filters if they are clogged.

Check the state of the oil. Drain out stale oil and replace it with a fresh one.

Finally, if your mower won’t start, it could be due to a low battery. If the battery is producing less than 12 volts, charge it. 

2. Engine Overheating

Overheating of the engine is another common John Deere 1025r problem. 

Engine overheating is usually a source of concern to vehicle owners because it can result in a loss of power and eventual engine damage, if not dealt with.


  • Debris accumulation in radiator fins
  • Dirty air filter
  • Fan belt issues
  • Stale engine oil
  • Low oil level


It is easy to have an accumulation of grass and debris in the radiator fins which will lead to overheating. Clean the radiator fins to get rid of this problem.

Clean the air filter if it is dirty or replace it entirely with a new filter.

Fan belt issues may cause overheating. A fan belt that is not working properly should be fixed or replaced. You should also make sure that the fan belt is tightly and well positioned.

Then, check the oil level using a dipstick. Top it up if it is below the ‘Add’ mark on the dipstick and drain and refill the oil compartment if the oil is darkened or stale.

3. John Deere 1025r PTO Problems

Some users of the JD 1025r complained about issues with the PTO. 

In most cases, the PTO shaft was unbalanced and kept causing issues even after being replaced.


  • Unbalanced PTO shaft 
  • Weak PTO bearings


Replace the PTO bearings if they are weak and causing a lack of balance.

Contact your dealer to replace or cut the PTO shaft if the issue continues to reoccur.

4. Hydraulic Transmission Problems

The hydraulic transmission system of the John Deere 1025r can develop some problems over time.

These problems include, a loud whining sound coming from the transmission, slow movement, and the tractor’s inability to move forward or reverse.


  • Stale hydraulic fluid
  • Insufficient fluid level
  • Clogged oil filter
  • Worn belt 
  • Pump issues


Replace the hydraulic fluid if it has gone stale. Check the vehicle’s owner’s manual to know when and how to change the fluid. Top it up if the fluid level is low.

Check the fluid filter and replace it if it is worn or clogged with dirt and debris.

A worn or damaged drive belt will cause movement issues in your JD tractor. If the belt is shredded, torn, or glazed, you will need to replace it.

Pump issues may cause a whining sound from the transmission. Disassemble the pump and replace any damaged shaft, bearings, and other parts. Replace the pump if necessary.

5. Rock Shaft Problem

The 3-point hitch is raised by moving the rock shaft. Loose or fallen snap rings can cause the rock shaft to shift. If the rock shaft is knocked loose, the lift arms are also harmed.

In some cases, the 3-point hitch keeps falling right back after being raised, in other cases, it refuses to come down when controlled with the rock shaft lever.


  • Loose rock shaft lever bolt
  • Fallen snap rings
  • Worn rock shaft


Tighten the rock shaft lever arm bolt if the rock shaft arm is too loose and falls back.

You may need to take off the tires to access the rock shaft lever arm bolt. You can also check your owners manual to find the location of the bolt on your tractor.

The rock shaft lever may be worn or damaged and will need to be replaced. It is best to have a mechanic or professional do this. 

6. Brake And Steering Problems

It probably doesn’t need to be mentioned that any issue with the brakes or steering could be fatal when operating your tractor—or any other machine, for that matter.

If you notice that either mechanism is taking longer to respond than is typically required, stop the machine and address the problem before continuing your work.


  • Loose steering wheel
  • Brake issues
  • Deflated tires


Your tractor might not have flat tires, but you should check them regularly to see if they are inflated properly.

Inflate lessened tires with a tire pump if you find any with a lower tire pressure than required.

Check the steering wheel and brakes for any loose or damaged components.

Fix the problematic component or replace it entirely to solve your brake and steering issues.

7. Excessive Fuel Consumption

You may find that your JD 1025r tractor consumes fuel excessively, faster than it should.

This is usually caused by problems with one of the fuel delivery components.


  • Leaking fuel injectors
  • Fuel tank leakage
  • Overheating


Check the fuel tank and fuel injectors for any leaking parts. Replace any if found.

Engine overheating can also cause the engine to consume more fuel than usual. Clean the air filter and radiating fans to cool the engine.

Change the oil if it has gone stale and top it up if the oil level is low.

8. John Deere 1025r Electrical System Problems

Some users of this JD model reported electrical problems with their tractors.

Most electrical problems stem from the battery, wiring, and starter. 


  • Low battery voltage
  • Dead battery cells
  • Corroded battery terminals
  • Faulty starter
  • Failed starter solenoid


Charge the tractor’s battery if it is producing less than 12 volts. Dead battery cells will result in the refusal of the battery to charge.

Make sure all battery connections are secure and try to charge the battery. If you discover that you have a faulty battery, replacing it as soon as possible is the best course of action.

Cleaning the terminals regularly can greatly reduce corrosion, which is a major problem.

Check the starter and starter solenoid as well and repair/replace any faulty parts as necessary.
