Problem 1: Engine Does Not Start

This is the most common problem of John Deere 4110. It is primarily linked to complications in the fuel system.

If the fuel filter is damaged or clogged then the engine will not start. A corroded or loose connection and damaged or worn piston rings are also the causes behind the engine’s hard starting. 

Check these components one after another to diagnose which one is causing the issue. 


Following are some of the symptoms that can lead to the engine not starting:

  • Engine is hard to start.
  • Random misfire in the engine mainly due to a clogged fuel filter.


First, check for any corrosion or loose connection in the starter motor terminal. Clean the corroded wires with a corrosion cleaner or connect the wires properly if loose.

Make sure to clean the fuel filter if clogged with a fuel system cleaner. If damaged, replace the fuel filter. You also need to replace the piston ring if broken or worn and lubricate it properly.

Replacing the Fuel Filter:
  • First, locate the fuel filter. Make sure the fuel level is low. 
  • Close the fuel shutoff valve. 
  • Remove the fuel filter by twisting it clockwise and catch the excess fuel in a drain pan. 
  • Apply some fuel on the inner side of the new fuel filter and set it up on the filter head. Put the new filter up by turning it anti-clockwise.
  • Check for leaks and open the fuel shutoff valve to turn it on. 
  • Now, fill it up with fuel.  

Problem 2: Engine Hard to Start

The John Deere 4110 can be hard to start if low voltage is supplied due to a low-charge battery. Your engine will have difficulty starting if the fuel filter is clogged or damaged. 

Now, a damaged piston ring can also cause the engine to have difficulty starting. Damaged piston rings mean heat cannot be transferred properly to the cylinder component.

This leads to multiple problems, engine hard start is one of them. Idling the tractor for a long time can also cause this problem. 


These are the problems that you might expect to see with damaged piston rings. Finding these problems mean that the probability of an engine hard start is high.

  • Engine stalling.
  • Power loss in the engine.
  • White or gray exhaust smoke.


To solve the engine hard start on your John Deere 4110, make sure your battery is properly charging. If the battery is drained quickly or doesn’t hold the charge longer, the battery should be replaced. 

If the battery isn’t at fault, clean or replace the fuel line, fuel filter, and fuel injector. Replace if the piston ring is worn out or broken. Avoid long periods of idling or making frequent stops.

The process for cleaning and replacing the fuel filter has been discussed above.   

Replacing the Fuel Injector:
  • First, check the connection lines.
  • There should return line around it, and remove it using a wrench.
  • Remove the fuel injector inside.
  • Find the tap in the fuel injector. Pick it off and remove the washer in it as well.
  • Put a new washer into this tap.
  • Put this tap over to the new fuel injector.
  • Connect this fuel injector back to the line.
  • Finally, put all the return lines.
Replacing the Piston Rings:

In order to replace piston rings, you need to remove the engine components and put them back properly after the work is done.

The process itself is complicated and a mistake can lead to engine damage. If you want to do it yourself, you can follow this guide.

Problem 3: Engine Overheating 

Engine overheating is caused due to low coolant levels. If there is a lack of any coolant or it gets leaked then the engine will overheat.

Worn-out fan belts, clogged radiators, and excess fuel can also cause engine overheating.
