2007 850D Parking Brake Switch

Hi all,

I'm trying to locate the parking brake switch for a 2007 XUV850D. Supposedly the gator in question had the switch previously, but it no longer does. I haven't been able to find a part number anywhere for a replacement part, either. The parts manual doesn't even illustrate it. The physical terminal for the switch is there, and the parking brake light is as well, but the switch itself is non-existent.

Anyone have any idea where it is located or where I can get one? Did JD even make a switch for this model?

I noticed on a 2014 HPX how the switch should look, but on the 07 it doesn't appear that it would be the same...

Thanks in advance.

If I’m not mistaken, the parking brake is activated by the lever in the console. If you pull on the lever, the brake light icon on the dash should illuminate. If the lever is depressed the dash brake light should turn off.

I’m not aware of any auxiliary electric type brake switch on the Gator 850d.

Please see screenshot below look at part number 38 with red line to the left.



Please report back on your findings.

Hi Bradhill, thanks for the response. I believe you are correct, but unless I'm mistaken, the parking brake lever actuates a switch which in turn illuminates that light on the dash. That switch is what I'm missing.

Attached are a few images I took.

The circuit schematic (1st pic) shows that wires 810 Pink and 420P Yellow go to a "Park Brake Switch" labeled S3. Within the main wiring harness diagram, this switch would be attached at point #35, which is the terminal as seen in the list (2nd pic). I took a pic of the terminal wires themselves as well (center pic).

I also included a picture of the parking brake switch from the 2014 HPX 4X4 (4th pic). I was thinking about just buying one of these switches and trying to install it on the 850D brake lever, but there doesn't appear to be anywhere to mount it that would actually allow it to work.

Please keep me updated with whatever you all may find out. My company just threw $2,600 back into the machine to get it refurb'd so I'd like to make sure it's as functional and mint as possible

According to partscatalog.deere.com

The switch appears to be integrated within the lever?

Have you looked at the lever closely? See number 13 on diagram.







The cost of replacing the lever with switch is rather spendy.

I apologize, I didn’t make it out to the farm last weekend as planned. I hope to get out there this coming weekend and will take a couple of pics when I do. If I can find a part number on the switch I will make sure to get it for you.

Hi all, the switch being integrated with the lever itself seems likely, I just can't figure out where the wire connectors would plug into on the lever. Attached are a few pics I took a bit ago after removing the console. The first two are from above, the third is from beneath. I apologize if they aren't rotated correctly or aren't too helpful, I'm replying from my phone and couldn't get my phone to light up the areas I was actually looking at, especially while I was under the machine. Can anyone point it out? Are the connectors in the center of the lever? Would I have to remove the lever to connect the wires?

Thanks for all your help.

Looking at the second photo above it appears the “white” roller is part of the micro switch for the dash light.

I believe you will need to remove the lever, the wires may likely connect on the bottom of the switch?

Good luck

I was thinking that might've been something. It's a shame it's not easier to get to. Oh well, I'll look into it deeper the next time the machine's out of service for an oil change - should be soon. I'll report back with the findings when I do! Thanks

I looked at mine without taking all of the console out and the wires appear to come out the back of the lever and plug into the terminals you have pictured. Looking at your 2nd pic, does it look like wire ends burned off at the back of the switch with the white roller? I can’t get the pic I took attached

Ah, okay. Thank you for confirming that! I'm not sure if it's burned or if that is just dirt/grime. I'll definitely take a closer look to see if it's burnt up the next time I work on the machine
