JD 3320 what is this switch for ?

[pokerboy57]

I own a JD 3320 I've looked at this switch for 3 years and have no idea what function it has and more importantly under what conditions I would want to use it ? Any help would be appreciated.

Total shot in the dark as the cab controls look a little different but is that your speed lock cruise control?

Maybe this will help you (the switch location in the picture should help):

This is from the Deere manual for the cab tractor instruments. If your tractor is an open station, take a look here:

thanks guys so it's a load match switch ..... SO when and why would I use it ?

I use mine when using front bucket getting a deep heavy load, for dirt and stone and when climbing a hill mowing or moving stone or ag...kinda acts like a governor.

Loadmatch will drop the transmission range down as soon as the engine begins to lug/stall under load... allows you to work at the speed you think you want to until the machine determines you picked the wrong one and "downshifts" to protect itself/keep you working.
Mine has only been turned off a handful of times... if you haven't had it "on", turn it on! Works great & keeps you from having to stop & shift constantly doing loader work & ground-engaging... also if you're transporting & hit any grade ("C" is anemic). I don't believe the PTO is influenced by it, except it keeps rpm's up when your mistaken selection range would start dragging the engine down.

I keep mine on all the time too. Although in almost 3 years of year-round use on 30 acres of steep Kentucky hillside, I've yet to experience it "downshifting" the transmission range. Mine intervenes as a rpm versus speed manager only. See LoadMatch switch
