Error 20 ?

[reprosser]

Anyone know what error 20 is for 3240 HST? Was backing out of some heavy brush, and it just shut itself down and now shows Error-20 on the display. I think I have a branch stuck next to the hydrolics on the right side. Too dark to tell tonight.

I am looking at my book(owners manual)and error 20 says "communication error between ECU and the IntelliPanel" but error 20 is under the GST glide shift tansmission and not a HST section.. error codes in my book show 80 thru 94 error numbers for HST. The GST has error 00-65 numbers? I bought my tractor in July it is a 3240 GST but the books are for all the 3240's, so my book is new.

yeah - I missed that in my manual. Just looked under the HST codes.

Found the broken connector. It (used to) plug into the side of the main rear housing, but looks like a branch or something just stripped away the connector. Just some broken plastic showing.

I removed the sensor and took it to local dealer. They say it is a speed sensor and will order a replacement - for $91 ! WOW

I will have to make sure that the new one is better protected. I cannot afford to loose them at $91 a pop. It sticks straight out from the side of the housing - right in line for anything taller than the deck to brush across it. (and I have lots of undergrowth on the property that is chest high...)

Resurrecting an old post. Trying to be efficient yesterday, mowing (well clearing) an overgrown pasture before it got to hot, I made a decision to just take out a fledgling hedge tree in my path. Heck, it was only about 4 inch diameter and ten feet tall, the FEL protects the radiator, I hunkered down and went over it. Always impressed by the 6 foot BMB monster. She groaned a little bit but ate that hedge tree fairly well. BUT, there was still signs of a tree out there, so on my return pass I decided to go over it again in the other direction

Then ALL fell SILENT. The Kubota L3240 HST shut down and flashed ERROR 20, WHAT is that supposed to mean??

Luckily I store a copy of my manual behind the seat, I pulled it out and it said,

Error 20, Call Kubota.

Geez, I am about as far from the house as I can get on my property, it is around 10 am and just creeping over 90, and I am STUCK. Well I called Kubota, we had a good laugh, I found a wire unplugged on the right side of the transmission. The wire and connector looked OK, But the piece sticking out of the transmission had taken the deathblow from that hedge tree.

I walked back to the house to get some tools and let the tractor cool off, I knew that pulling that sensor was going to get messy.

I rolled back out on my trusty Honda Forman, laid a tarp out under the tractor so that I would NOT be laying in chigger heaven and removed the sensor. As I laid there trying to catch as much Super UDT in a pan as I could, I attempted to concentrate on not LOOSING anything. But somewhere in the excitement of the UDT shower and the recognition that I had lost the battle for containment, I LOST the fastener.

NOTE to self?
1. STOP trying to mow over trees!.
2. Also do better HANGING on to things in the middle of the pasture!

I was able to order a new sensor (and HOPEFULLY the CORRECT fastener), but it will take a week to get here. Of course, AFTER I took the plunge (literally in the UDT skin conditioner), It HIT me,

IS there a MANUAL OVERIDE to the L3240 computer?

I think that the sensor that was damaged was for PTO speed. I can see why that would be necessary for computer operation, but is there a manual over-ride that would at least let a person get back to the driveway to make a mess?

Heck it is too HOT to mow now anyway. This is probably some good karma to keep me from playing all week trying to mow when it is too darned hot to be doing stuff like that. But it was AMAZING how fast that tractor shut down. Sure hope that the sensor gets here next week. I am probably going to pull that tractor off the spot with a truck and spend some time looking for that fastener in the next few days.

Any chance of posting a photo of this sensor location so maybe I could make some sort of protection for it before this happens to me?

I have an L3540. Yesterday in thick brush the tractor shut off and I got an "error 20". I read this thread and assumed it was a broken/disconnected wire underneath the tractor. I spent a lot of time looking under the tractor but never saw anything obvious. For the heck of it, I checked the fuses. I found the "Control P" (10 amp) fuse burnt. I replaced it and the error 20 message disappeared and the tractor started right up! I used it for a couple of hours afterwards and it appears to be operating normally. Try this before taking it to the dealer. I don't know if the brush was just a coincidence or what, but I am glad I checked the fuses!

I encountered this error today on my 5740. The workshop manual basically says to replace the ECU, but fortunately that's not the problem. As noted earlier. the problem is the wires getting pulled off the connector for the travel speed sensor on the right side of the transmission just forward of the rear axle. In my case the wires were pulled out of the plug, and the plug shell broke at the same time.

But what I discovered is that the broken connector is the first of two problems that result in the ERROR 20 code. With the dangling, exposed wires, they can short and that blows one of the control fuses. With the fuse blown, ECU communications is disrupted and the get ERROR 20.

I found that if you tape up the wires so they are protected and can't short, then replace the fuse, the tractor will run just fine. I was able to finish mowing, and get the tractor back to the shop. Now I just need to get a new connector shell.....
