I know the different sensor’s on CNH but never heard about this on MF.
It’s auto-steer ready yes, but without autosteer, in fact speedsteer mode use the valve to steer the wheels with less angular movement of the driver on the steering wheel. Anyway that mode allow to get the desired can messages for guidance.
@Cat_Doctor
Very interesting, now if I must go to the dealer I have a clear idea of what to ask!
I already tought about checking the WAS next time, but I had nearly no hope that it could be adjustable, your message give me that hope again, that’s very nice to know.
However, as you said, the difference to center position seem big and I’m not sure there would be enough slotted distance, but it worth to try it…
Thanks for all this!
By the looks it is like cnh axle.
Sensor in top of king pin. 3 screws under holders for mudpad.
The wire you show in picture goes to a 3 pin connector that sensor fit down into (in center of king pin)
Don’t remember if sensor house is totally circular under the 3 screws, so house can be adjusted as you like.
Good monring BL08,
The housing you have disassembled is the junction box. The sensor lead and the tractor’s engine harness meet here. This would most likely be the DANA 750 or Dana 755 axle. I have attached the parts manual page for you to reference. Item 11 is your actual W.A.S. I have also attached the section from the WSM regarding the removal/installation of the W.A.S. Let me know if you need any further assistance. 750 Front Axle WAS.pdf (1.3 MB) wk051039-1.pdf (118.3 KB)
Thanks for anything, really useful.
I understood with it it’s like russian roulette to adjust manually as after you re-assemble, if you aren’t exactly at the center you have to dissasemble again!
My dealer have problem with EDT but we will adjust thanks to it…
By the way, I saw EDT licence around 200€ from china, but what about the can-usb interface?
The AGCO one cost minimum 700€!
There is a cheaper alternative or not?
Puh, I am also looking for the CanUSB.
Tried to get a fake one on aliexpress, but they wanted 6000€ for it. At least in Germany you get one for about 5000€ on ebay. The Interface is made by Sontheim Elektronik but they do not offer it. With the interface they sell you can only have access to the engine control unit.
Where to find the CanUSB for 700€;?
BL08,
Unfortunately I do not have a CAN box to spare. I do know that there are pirated versions of EDT available but I’m not sure if there is an offbrand CAN box as well. Ferdi is correct and the boxes are made by Sontheim, they used to be sold by Snap-on but I’m not sure on availability any more as everything seems to be in short supply these days. In addition to the box you will need an adapter cable 930.203.600 (ATP8089) which just adapts the 9 pin Deutsch connector (at your X183/X184 diag ports under the right hand cover in the cab) to the 7 pin on your CAN box. With the rollout of TCD (AGCO’s latest diagnostic tool) the dealers are now renting laptops with EDT and all necessary cabling. I believe the price was approximately 500$ for 3 months, which in my opinion isn’t worth it if you can buy the pirated version for a tick more and a CAN box (odds are you’ll need it later down the road if you do your own repairs).
Let me know if I can be of any other assistance.
Free Internet Connection
Using the smartphone for hotspot in the past was fairly easy, but not very comfortable.
I used a cheap 4G USB surfstick (Alcatel one touch L850V) and the “netzclub sponsored basic” cellphone tariff, where I get 100mb/month free highspeed data usage. After that, transmission rate is 64kbit/s - this should be enough for RTK correction. You can sign up (for free) in Germany only, but using it is possible in the entire European Union.
We have mf 7724 2016. I thought it was autosteer ready but now I think mayby it isn’t. There is X230 socket but no autosteer button on side panel and no socket on roof. I tried to look if the is eny wires going to orbitrol and I did not see eny. In front axle, left side, there is a cable going inside so there is a sensor?
If there is a sensor for wheel angle can it be used for AOG via can bus or is it different kind of sensor for only 4wd and dif.lock use?
I would be grateful for eny help. I’am geting more and more interested on autosteering every day and thinking of doing a project of my one.
You can very likely poll the WAS over canbus - that’ll be there to trigger 4wd/difflock disengage as you steer. If there’s no autosteer button on the pillar, I’m guessing it won’t. But try it !
I think the Massey Fergusons that are equipped with auto steer ready hardware have 2 or 3 extra buttons on the right side of the cabine (under the 4wd and dif lock buttons). On the picture the tractor isn’t equipped with auto steer and misses the buttons.
Hey, have you solved your problem? I have the same problem with the centring. However, I can’t get to the menu on Cat_Doctor’s screenshot with the edt. According to my dealer, an extra auto-guide box is needed. Auto-Guide is activated in the main menu, but I can’t get to this callibration menu. Does anyone have any other ideas on how to set this up?
No other box is needed, all those settings are done in the valve via EDT on the older tractors and the newer tractors ones it’s inside the main tractor ecu.
What model tractor? Did you know if it has a PVED-CL (old) valve or PVED-CC (newer S models)
No, but maybe yes.
Calibration of the steering sensor was done by my dealer, however barley seeding arrived, I focused on another machine for the moment and didn’t tested yet.
Probably there is just to plug-in and adjust now but now we have too much work and no enouth time (it’s a special year for us), I plan to finish my 7720 this summer but my “new” sprayer before and I’ll tell you then but I believe you’ll be faster than me…
Just a trick for everybody NEVER leave a board nude for test that someone can make shit with, especially if this can lead to SHORT THE CAN WIRES.
We have also MF autosteer ready tractor.
We would like to control the PVED valve through CAN.
We have tried to send the following msg every 100 ms:
data[0] = 234; //example
data[1]=124; //example
data[2]=253;
CAN0.sendMsgBuf(0x0CAD131C, 1, 8, data); //Send CAN Curve Command
When I press the autopilot button, I feel like the valve gets activated for a very short time (few hundred ms), and then it goes off. The wheel does not move actually.
