Error code 20, plus screen reads “Depress Clutch”

[BudGoat]

Tractor will not turn over from ignition switch, only be jumping across starter solenoid.

Error on screen is 20.

“DEPRESS CLUTCH” message. So I tied the clutch pedal down to actuate the safety switch. Still no crank.

Any tips on how to get it started?

Test or replace the switch that the clutch operates???

 

[BudGoat]

I tested the clutch switch and it had continuity when depressed. Not sure where to look next.

I had a similar issue on my L4740. I was seeing multiple errors preventing startup, so I went through and tested/jumped each of the safeties to find the culprit. In my case I think the post the clutch switch was bolted to got bent, so the clutch pedal could not depress the switch enough. I bent it back and redid the PTO switch bypass and I was back in business.

Instead of just checking the clutch switch, can you try jumping it temporarily?

 

[Russell King]

If you need it running you can turn on the key and jump the starter. Unless there is some safety switch involved it should start and run.

Just be careful not to get run over by the tractor if it starts in gear.

I have no idea what type of safety control is on your tractor but you just need fuel, air and compression to run so older tractor can run with the key in the off position.

Check all your fuses. You might have a dead short somewhere in your harness.

My clutch pedal assembly was bent by a tree branch intrusion a few years ago. I bent it back with a pry bar and sledge hammer. It worked passable all this time. But I will test it electronically when reinstalled to be sure.

I checked all, all good.

I am going to go through all the safety switches as you did.

I did jump the switch’s plug with a bare wire and it still would not start when turning the starter over by jumper at solenoid with key on.

I jumped it at the switch but still no fire or start up

I will take your advice and start at the PTO switch and work around to all the others. Thanks

You really need to start with the wiring diagram from the WSM.
You need to KNOW what switches are involved with 'no start' and 'depress clutch'.
Does the 'error - depress clutch' go away when you short out the actual clutch switch connector ?
Why look at PTO switches when the error says 'depress clutch' ?

 

[Schmitty]

Do you have an L3240-1 or L3240-3 HST? Here is the ERROR-20 text from the LXX40-3 WSM:

And the wiring diagram:

The ERROR-20 communication issue is something I've not had to troubleshoot and is concerning. I have an LXX40-1 WSM, too, if needed. Can you jump all the way to the ECU, i.e. with the seat and seat pan out of the way?

 

[GreensvilleJay]

curious, just where doers the 'depress clutch' message appear ?
and

this tractor WAS working fine before ? what was the 'history' ?

Thank you for the wiring diagram. Mine is the HST model.

I found a couple safety switches (eg, the PTO and parking brake dog) that were worn out. No continuity even when depressed. I will buy new ones and t

I checked for voltage at all the safety switch plugs after removing them and all were positive for 12volts

I learned that using rusty wire to jump across connectors at switches is a bad idea. Rust insulates a bit. Will retest with clean new wire.

I will print out and study the wiring diagram and see what to test next.

thank you

I called that one switch the parking brake dog in error. It is most likely the HST Pedal Sensor.

The tractor incident “history” is included in the initial post.

the depress clutch message comes onto the screen when you hit the starter key. The massage shows up where it states ERROR-20 in the attached photo. The depress clutch message flashes into the screen then disappears

OBTY. The immediate issue started when I ran it out of diesel on a very steep hill. It cranked by key a bit to prime engine but never fired.

To test switches can I bypass them with a jumper wire or paper clip?

 

[GreensvilleJay]

not necessarily, depends if it's a NC or NO switch for operation.
normally to 'test switches' with an ohmmeter(beep is closed, ----- is open )
