Now you have found the switch that controls the ignition. The next step is to remove the ignition key. 

In order to accomplish this, you will first need to turn the key so that it is in the “Off” position. And then you will need to carefully remove it from the ignition switch.

Step 3: Install the New Ignition Switch 

The next step is to turn the ignition switch on with the new key. You will need to insert the key into the switch to accomplish this. And then turn it to the “On” position. 

If everything works as it should, the engine will start when you turn the key to the “On” position. 

But there is a chance that the engine would not turn over. Then you will need to investigate the possibility that the problem is with one of the engine’s other components. In that scenario, visiting a John Deere dealership is recommended. 

Problem 2: Not Cooling Properly 

Overheating is pretty common with tractors. And finding the proper cause behind it can be tricky. 


Diagnose the cooling system to find the faulty component. Then repair or replace the faulty component. 

Step 1: Check the Coolant Level

Check to ensure that there is sufficient coolant in the radiator. It is possible that there is a leak present if the coolant level is low. Or perhaps there is a problem with the way the coolant is circulated.

Use the user’s manual for locating the radiator. The user manual will also be helpful for all the upcoming steps. 

Step 2: Check the Radiator 

Conduct a thorough inspection of the radiator as well as the hoses, looking for any obvious evidence of damage or leakage.

If you discover a leak, it will be necessary to get it fixed. If it is not fixed, you will not be able to use the tractor again.

Step 3: Check the Water Pump 

Check to see if there are any obvious indications of damage or wear on the water pump. If there is a problem with the water pump, the tractor will likely overheat. That is because the pump recirculates the coolant through the system.

Step 4: Check the Thermostat 

Make sure the thermostat is in good condition by giving it a thorough inspection. The thermostat is responsible for controlling how much coolant moves through the system. Tractors with defective thermostats have a higher risk of overheating.

Step 5: Replace the Faulty Component 

By now you have identified the faulty component in the cooling system. Replace or repair the faulty component to solve the cooling issue. 

The cooling system is quite complicated. Working on it with amateur skills is not recommended. So if you do find a problem, consult a mechanic or go to the John Deere dealership.

A wire harness can be found attached to the back of the tractor. It can be found on the right side of the vehicle’s rear end.

The wire harness has a wire that runs in a direction that is opposite to the other wires. It is a two-conductor cable that has a plug attached to it.

You will be brought straight to the switch that controls the PTO solenoid when you follow it.

Step 2: Unscrew the PTO Solenoid

The solenoid for the power takeoff (PTO) is the one on the left. To unscrew the 14-inch driver, the 14 mm socket will need to be used. Remove the plug from the wire as well.

Step 3: Take the Diverter Body Off the Transmission

It is necessary to empty the transmission fluid before removing the diverter body. Put a bucket or a towel under the work location you’re going to drain as you do it. This will prevent a mess from developing later.

The diverter body is attached to the transmission using four bolts. These are bolts with a 10 mm diameter.

For your help, take pictures of the setup. During the process of putting everything back together, this will be of great help.

After removing all of the bolts, carefully remove the diverter body from the housing.

Step 4: Install the New Valves

To remove the valve bodies, you will need to use the 7/8 box wrench. Now remove the old valves from the diverter body and put the new ones in their place.

Now, reattach the diverter body to its original location. Carry out the preceding stages using the opposite approach this time.

The problem ought to be fixed. In the event that the problem with the PTO persists, the issue is most likely with the PTO clutch. If this is the case, the John Deere 6135e should be taken to a mechanic as soon as possible.
