JD 6610 pto problem

[wr.]

JD 6610 slipping out of pto. My son said he has to push the pto lever/button back down and lift it again to start the pto when it disengages itself. It doesn't always come back into gear first time. Thinking the trouble is in the switch but has anyone else had the same problem? The tractor is on the feeder so it's a bit of a pain at the moment.
Any ideas before I go poking around please?

On the 7000 series you could swap diff lock solenoid wires with pto wires, if it stays running then you need a switch

Possibly the switch , but could be the ECU , we had this problem with a 6510 and had the ECU repaired for £90
when the dealership wanted £1500 for a new one ,

Mud guard button causing grief?

No mud guard button on this one.

First of all try the solenoid, swap it from the difflock, if that makes no difference then it could well be the switch, if not the switch then it could be the mosfet in the bcu, but that could take a while to sort by the time its sent to david kings.

Now Then..
It's often the PTO switch. Is it a Premium type tractor or an SE??
On a Premium type tractor, the codes are accessible through the screen. See the operators manual for details..

Pto switch on 6800 here did the same about 10 years ago. New switch and been fine since. 6410 still on original one.

Premium type. Thanks, I'll check codes when I get a few minutes to myself.

Solenoid on back, had to replace ours on 6910 (if it's same) 3 times in about 8000 hours, no idea why keeps failing but it's in a position that gathers debris/water so maybe that...

Same symptoms every time, pull up PTO knob and it'll work for few seconds/minutes and drop out, or sometimes won't engage at all. Save yourself £80 on the switch till you check solenoid... Have a switch laying around on shelf here...

JD 6610 DIF lock fault

Got a year 2000 JD 6610 premium. Recently when you engage the diff lock the diff lock light comes on .after about 10 seconds the diff lock light starts to flash and it disengages the dif lock.to stop the diff lock light flashing you have to put the diff lock back in and then push the brake pedal...

thefarmingforum.co.uk

this was a thread a week or so ago about diff lock problem. Swap the solenoids as described. This is a common fault and looking at it this way means you don’t waste money on parts that are still serviceable.

It was a solenoid problem. Thanks for all advice.

Have a similar problem with my 6210. When engaging PTO, it takes a few twists to the button to get it going. Will then run for about 2-3 minutes and stop, the blue lamp starts flashing. Then turn off switch and repeat a few times to get it going. Have tried to swap leads with diff.lock. pto runs as long as I can keep my foot of the brake. Therefore i assume the solenoid is ok. Also replaced pto speed sensor.

Have you tried the switch?

Have you tried the switch?

No. This was my next move. Are there many wires,or just two to jump?

More than two wires, can't remember how many sorry, can you try another switch?

 

[Kalvegjerdet]

Have searched a bit online and it seems like there is three leads. One hot (+12v) and one that is powered when pto is engaged, and one wich is powered when pto disengages. Will try to figure out which is what.

 

[Kalvegjerdet]

Have you tried the switch?

Now I've measured the switch, it seems to work as intended. Will my problem create any fault codes except from the blue (!) flashing? Because I can't find any codes. I have two yellow lights flashing occasionally. The battery symbol and the yellow central warning.

Is this a normal spec tractor or the 'poverty' spec SE version??

The seller (which I doubt tells the truth) told me it was a premium. Chassis nr L06210V274681
