Pto mudguard switch jd 6420

[aidan]

The pto switch on the mudguard of our jd 6420 is getting sticky, 2006 common rail

is it possible put a drop of oil in it somehow or is it a strip down and clean it or is it a new switch

Just replace it. They go electrically open circuit then youll suddenly have no pto

No, tried some WD40 round ours and made it worse.... swelled the plastic expect.
As above, I’d get a new one.

Replace both sides when you’re at it, mine went a month apart

Replaced a seized one on our 6630 and I am still getting intermittent PTO drop outs

Now Then..
A replacement switch is the only solution (other than a paperclip)..

a new switch from john deere is only about £30

Replaced the switch a week ago and only got to use the tractor with the PTO for the first time today. Im informed the PTO is turning slowly, only half the speed it should be, and all it was doing is pottering around with the fertilizer spreader.

Informed too its reading 540 as expected on the dash.

Any ideas

What are you saying here??
The speed indicated on the display is 540 yet the shaft is actually turning at 270?? How has this 270 been measured??

a guesstimate that its only half speed, I guess I should have said it appears to be slipping.

What speed do you have selected on the speed selector lever?? Is full power available for the task in hand??
