3720 Motion Match

[greg_g]

Before I go to the dealer and try to make this a warranty issue, I'd like to make sure it's not actually an operator error. It's a 3720 cab model with eHydro, Load Match, Motion Match, automotive style cruise control. I have the Load Match workin' fine, cruise control too. Motion Match however, is being a PITA. Biggest problem seems to be that it's a 2011 model, and there have clearly been changes to the cab layout made since the operator manual was written. I've followed the limited Motion Match instructions in the manual, with no satisfaction. And my dealer so far hasn't impressed me in knowing much about 3000 series operation. So I'm kinda wingin' it here.

Tractor was delivered with Motion Match set to 5 (mid scale). I'm in 1 now. Problem is that it doesn't make a lick of difference where I set the Motion Match on the 1 to 9 scale. Nothing changes. Whether going forward or in reverse, as soon as I take my foot off one of the go pedals - the tractor lurches to a halt. When running with cruise control, as soon as (a) hit a pedal, (b) tap the brakes, (c) change directions, or (d) disengage the cruise control switch - the tractor lurches to a halt. And the lurch is sudden enough to where the R1 tires actually tear up the pasture sod. When doing so at 17mph on the highway is a bit unnerving too.

Am I doing something wrong? Or is this something I should bring to the attention of the dealer?

I am no expert on this by any means...but I though there was a separate program that's standard for the rate-of-deceleration that is unrelated to the MM option/upgrade.

Sounds to me like something is definitely wrong. I have an 06. 3520 open-station. and there is a hugh difference between 1 and 9 on mine. Mine has a "short" / "long" switch. The "short" can be set anywhere from 0 to 4, and the "long" can be set from 5 to 9. I have mine set to "3" and "8" respectively. I use "short" when operating at low rpm or in very tight locations when I need maximum control. When mowing the field I run at pto rpm with the cruise set at 4 to 5 mph and mm set to "long". When I disengage cruise the tractor will brake to a stop in about 8 to 10 feet. If I just switch to the "short" setting (leaving everything else the same), the tractor will brake so firmly that the rear wheels will slide for 1 to 2 feet (the large R4's, loaded).

I agree something's wrong, but I don't want to go to the dealer and find out it's me. But based upon your description, I don't have the same kind of MM setup you have. And the Hi/Lo settings you mentioned aren't described in my manual either. But then again - maybe the problem is the manual. Cuz it's already clear there are differences between cab photos in the book - and the actual cab layout of the 2011 model. Maybe I'm just not pushing switches in the correct sequence. Would you be so kind as to describe the procedure you use to engage/adjust/disengage MM on your '06? I mention this because there's also the word COAST on my status display, which one might assume is related to Motion Match.

Greg did you go to the online manuals and find your configuration listed? I checked the manual in instructions that I thought would be your model against mine 07 4320 Cab and they were the same instructions.

Changing MotionMatch Setting

1. Press and hold the display mode switch until the display reads Release?

2. Release the display mode switch and display should read Coast?

3. Press the display mode switch once again.

4. For machines without MotionMatch switch:

a. Push the turn signal switch and return to neutral position to change to desired setting between 1 and 9. Position 5 is displayed as DEF? the factory
default.

6. To confirm the changes for MotionMatch setting, press display mode switch once again.

This is all you should have to do providing your machine does not have the Motion Match Switch with the long and short lines on it.

'06, 3520 Motion Match instructions:

I had to pull out the manual - I played around with those settings at first, but once I found settings I liked, Ihaven't changed anything since. I also looked at the current 3520 manual on-line, and the instrucitons are still the same as those in my original printed manual. Hope this helps!

Using MotionMatch (eHydro)

MotionMatch enables the operator to adjust machine acceleration and deceleration rates. Shorter starting and stopping distances can be set for applications requiring rapid changes in direction, such as operating with a loader. Longer starting and stopping distances can be set to avoid turf damage in other applications.
A MotionMatch setting of 1 is the shortest rolling (starting/stopping) distance, and a setting of 9 is the longest rolling (starting/stopping) distance.
1. Fully depress top of MotionMatch switch for quicker acceleration/deceleration response levels, and to reduce machine starting/stopping distances.
2. Fully depress bottom of MotionMatch switch for slower acceleration/deceleration response levels, and to increase machine starting/stopping distances.
Changing MotionMatch Setting

1. Press and hold the display mode switch until the display reads è¿*elease?
2. Release the display mode switch and display should read 鼎oast?
3. Press the display mode switch once again.
4. For machines without MotionMatch switch:
a. Push the turn signal switch and return to neutral position to change to desired setting between 1 and 9. Position 5 is displayed as æ³¥EF? the factory default.
5. For machines with MotionMatch switch:
a. Push the turn signal switch and return to neutral position to change to desired setting between 5 and 9. Position 5 is displayed as �ONG_D? the factory default.
b. Push the turn signal switch and return to neutral position to change to desired setting between 1 and 5. Position 5 is displayed as 鉄HRT_D? the factory default.
6. To confirm the changes for MotionMatch setting, press display mode switch once again.

Yeah, all that's the same in my manual too. Thank you guys for posting that stuff by the way. But I've got the same OMLVU23778 (IO) that's available online, and they both read identical to what you posted. One of my problems is that my interior cab switch layout doesn't match the photo or labels/locations in the manual.

So since I couldn't positively identify a MM switch, I followed the "without switch" instructions. The status display responded exactly as the manual said it should. Only problem is, it don't matter what number I select - there's absolutely no effect. So I guess I have to gamble that I'm actually doing it right, and approach the dealer about it.

Thanks to everybody who tried to help so far. It may be a while before I get any dealer action - positive or negative. But I'll follow this thread up as soon as there's any progress to report.

I had an issue on one of ours at work , the switch wasn't working so i pulled the switch to find out it wasn't pluged in . simple enough to check , your dealer may just send out a tech instead of trucking it in .
