Deere 6800 revs for 540 PTO speed?

[Nla01]

Hi - we’ve recently purchased an old (P reg) 6800 and will be running the pto at 540e but strangely theres no indication on the rev counter as to what the engine rpm should be. Can anyone with a 6800 tell me what it should be? TIA.

I carnt remember exact but it’s around 1700 rpm. Is there not a mark on the rev gauge on the dash?

Can you not get the speed on the dash by clicking the switch under the wiper stalk?

No - theres no indicator as to what the engine revs should be to run at 540.

No - theres no indicator as to what the engine revs should be to run at 540.

And no digital display on the dash?

Yes there is but this just tells me the revs - not what level i need to hold the revs at to operate the 540 at the correct speed..

So have you operated the switch under the wiper stalk?

Is the dash not the same as this picture? The yellow line is 540e 1750rmp

That's a 10 series dash?

This is what mine looks like - the rev counter

That's a 10 series dash?

Is it?? Its on the 6800!

Yes. On a 10 series the rev counter goes round to the yellow section when the pto is on

Oh...well this just adds to the mystery then!

Yep 10 series dash. The rev counter will go to the yellow part when you seitch between modes with the switch under the wiper switch.
If you make a photo of the interior it is very easy to see if it is a 10 series ot not.

Very strange as the tractor IS a 6800....obviously one of the previous owners has changed the whole dash for some unknown reason...!!

Ah right I see the top of the dash is black, 10 series is brown.
Not sure whether all the functions are interchangable. Maybe @Tractortech knows.

It seems a bit of a mix as the diff light is on the dash, 10 series has it on the right hand console.

So are you thinking its not a 10 series dash?

Get a picture of the actual dash and a pic of the underside of the windscreen wiper control,there should be a little black switch you toggle to select between engine rpm,pto speeds F and R and the last one is the hrs.
Also a picture of the tractor serial number.

The very last 6000 series where very similar to the 10 series so it might be original but I can't be certain.
