20 Common Problems of John Deere 1435 and Their Fixes

1. Engine Being Overheated

Engine can be overheated if there is a coolant shortage, or if the cooling system parts fail or are dirty.

In addition to that, broken belt or misadjusted belt tension might cause you the issue. Poor amount of engine oil can also be a reason. If your thermostat malfunctions, your engine will get overheated eventually.


Add coolant to the cooling system and look for any leaks to repair. Keep the system clean by flushing it. Change the faulty part or parts of the system.

Repair or install new belt if required. Adjust your belt tension. Ensure sufficient engine oil. Check and replace your thermostat if required, to refrain your engine from being overheated.

2. Engine Is Difficult to Start

You might find it difficult to start your JD 1435 in case the fuel filter is clogged causing water, air, or dirt in the system. Defective or dirty fuel injectors can make it happen as well.

Blocked fuel supply valve is also a considerable reason. Faulty fuel injection pump and poor compression due to worn cylinder block parts will lead to difficulties in engine starting.


Keep your fuel filter clean or change it, and bleed out the fuel system to avoid any air, water, or dirt in the oil.

Check your fuel injectors and take actions accordingly. Keep your fuel supply valve open. Examine cylinder parts to tackle poor compression. And take care of your faulty injection pump to have a smooth start.

3. Stops While Running

Your JD 1435 might stop while running because of the misadjustment of fuel injection pump timing, worn or dirty injector nozzles, dirty fuel filter element, damaged fuel injection pump.

Clogged air cleaner will do the same as well.


Adjust your fuel injection pump timing. Take care of your injector nozzles and fuel filter element. Don’t skip the fuel injection pump and air cleaner to check as well. Do the servicing or replace the worn parts if required.

4. Stops While Idling

The major reason for your tractor engine stopping while it’s running is the incorrect adjustment of low idle speed. Some other cases may be faulty fuel injector nozzles or injection pump, and inappropriate valve clearance.


Correct your low idle speed adjustment to avoid such suffering. Check for faulty fuel injector nozzles or injection pump and repair, or replace according to necessity. Fix your valve clearance if needed.

5. Making Weird Noises

You might have a loud engine while using your JD 1435 if any of the following happens to you.

If the fuel injection pump timing is misadjusted, the engine oil is insufficient, injector nozzles are worn out or dirty, you’ll hear noises out of the engine.

Cold engine, broken piston rings, worn out crankshaft (main bearings), or misadjusted flywheel screws may be a reason as well. 


Fix your fuel injection pump timing. Always have enough engine oil and replace worn fuel injector nozzles to avoid a noisy engine.

Give some time to your engine to warm up, repair or change broken piston rings and main bearings, and tighten your flywheel screws to stop the unwanted noises.

6. Battery Isn’t Charging

Battery might stop charging because of dead battery cells. It can be the outcome of another issue like damaged electrical wire harness in the battery system.

In other cases, there might be reasons like loose battery cables and terminals, and damaged belt or the belt tension is inaccurate.


Look for dead battery cells and install new ones. If the battery wires are damaged, repair or replace them. Take care of loose or corroded terminals as well. Fix the belt tension and replace the belt if required. 

7. Slow Starter Motor

Starter motor may turn slow as a result of low battery output, or if the battery drains faster than usual. Damaged battery wiring harness and corroded or loose terminals might be a factor in distinction. 


For a fair amount of battery output, keep the battery charged duly. For battery draining faster, do a servicing of the charging system or change dead battery cells if required.

Examine battery wiring and fix the damaged ones or replace them. Same goes for battery terminals as well. 

8. Starter Motor Stopping

Starter motor will eventually stop at a low battery output, damaged or worn out battery cells, or the motor itself being damaged. Improperly connected or totally disconnected cables can cause you the problem as well.


Charge your battery, or change damaged battery cells to keep your starter motor working. Change the damaged motor and connect the cables in a proper way to sort out the issue.

9. Difficulties in Gear Shifting

Your gear shifting will be troublesome in your JD 1435 if the clutch is not properly adjusted. It might be an outcome of worn gear shift linkage as well.

Some other reasons may be damaged shift forks and unfit gear-shifting mechanisms. 


Adjust or replace your clutch. Do servicing of your shift linkage and change your broken shift forks. Take out the faulty parts of the gear shifting mechanism and install new ones. 

10. Lack of Transmission Fluid Pressure

The very basic reason for insufficient transmission oil pressure is that the transmission fluid is low in amount over time. The related factors are like the dirty transmission oil filter and defective relief valve. 


Keep sufficient amount of transmission fluid, the transmission oil filter clean and fix or replace the relief valve to ensure the pressure.

11. Transmission Being Noisy

Transmission becomes noisy over time because of worn out bearings, low amount of transmission fluid, or the fluid being contaminated. Improper backlash, worn gears, and damaged shift forks can cause the sound as well. 


Change the damaged parts of the bearing or all at once, fill in transmission fluid regularly and keep them clean. If they get dirty or contaminated, change them. Replace backlash, gears, or shift forks according to necessity. 

12. Leak of Transmission Fuel

Transmission oil leaks only when the gaskets or seals are unfit, and the cracked transmission housing. 


Replace the gaskets or seal and the transmission assembly or housing.

13. Insufficient Hydraulic Pressure

Low hydraulic system pressure occurs due to insufficient hydraulic fluid. If the hydraulic oil filter and hydraulic pump is faulty then the problem will occur as well.

Worn or misadjusted hydraulic spool valve and damaged cylinder might be the reason too.  Don’t forget the leakage in hydraulic lines. 


Refill hydraulic fluid and keep the hydraulic oil filter clean. Change it if required. Look for the hydraulic pump flow and replace if needed.

Adjust the spool valve correctly and replace the damaged cylinder. If there is any leak in the system, fix it. 

14. Hydraulic System Getting Overheated

Your JD 1435’s hydraulic system might get overheated if the hydraulic pressure is not adjusted correctly.

Malfunction of the main relief valve either for being damaged or misadjusted, can do the same. The hydraulic oil being contaminated or air being stuck in the system will act as a factor as well. 


Adjust the hydraulic pressure and main relief valve or replace the valve upon requirement.

Change the contaminated hydraulic oil and bleed out the system to get the stuck air out for refraining your hydraulic system from getting overheated. 

15. Stuck 3-Point Hitch

3-point hitch is mainly related to the hydraulic system. So, if there is any issue with the hydraulic system, you will find your 3-point hitch stuck.

Check the hydraulic system issues as mentioned earlier. Look for damaged or loose suction pipe.


Upon finding any issues with the hydraulic system, take actions as required. Fix if possible or replace the suction pipe. 

16. Slow Dropping or Uprising of the Hitch

If the hydraulic fluid is cold, or there is any issue with the hydraulic system, you will encounter the slow dropping or uprising of the 3-point hitch. 


Give your tractor a while and warm up the hydraulic fluid to move the hitch smoothly. Take a closer look at your hydraulic system and do servicing as needed at the same time in the previously mentioned ways. 

17. Jerky Hitch

Your 3-point hitch becomes jerky because of hydraulic system failure.

To be exact, any air leaks in the system, the fluid being contaminated, the pump being defective, cylinder being worn out, or hydraulic control valve is inaccurately adjusted. 


Check the pump seals, other fittings and suction pipe for any air leaks and fix them. Change contaminated hydraulic fluid. Adjust or replace hydraulic control valve or any parts of the cylinder. 

18. Steering Hard to Move

Steering turns hard to move around if there is any issue with the steering column, any air gets stuck in the steering system, malfunctioning steering pump, etc.

Improper toe-in and worn out front tires will cause you the same problem. A silly reason might be insufficient steering oil or any oil leaks in the steering system. 

Worn out or defective steering box components and power steering valve can also make your steering hard. 


Check your steering column for any broken parts and fix or replace according to necessity. Bleed out the steering system.

Examine your steering pump and do servicing. Adjust the toe-in and install new tires if needed. Ensure there are no oil leaks in the steering system and refill steering oil duly. 

Look for defective steering box components and change them accordingly. Fix or replace the power steering valve if needed. 

19. A Pull to Right or Left

Improperly inflated tires and misadjusted toe-in will get you a pull to right or left in your steering. Worn steering box components and linkage can also do the same.

In other cases, if the power steering valve is worn out or damaged, or the front hub bearings become faulty or misadjusted, you’ll feel a pull to the right or left in your steering. 


Inflate your tires as needed and adjust the toe-in to avoid any pull to the right or left. Check steering box components for broken parts and take actions as required.

Replace worn steering linkage. Fix or change power steering valve and adjust front hub bearings. 

20. Excessive Free Play in the Wheel

When your steering shaft is worn out, steering box components are damaged, and power steering valve is damaged, then this issue happens.

In different scenarios, defective hydraulic steering pump and steering linkage can be a factor as well. 


Fix the defective part of the steering shaft, steering box components, and power steering valve or replace them if not fixable.

Change the faulty components of steering linkage and the defective hydraulic steering pump to avoid excessive free play in the wheel.
