Electric operated PTO problem

[steveR]

Went out today to finish off the top dressing with the compact tractor on some of the more,,, challenging land.

Into the field, and positioned and hit the PTO rocker switch and build the revs ready to head off... Nope, no PTO drive!

I had a little hiccup yesterday where the PTO failed to engage but then it kicked in and went OK afterwards.

Checked the switch, cables and connectors, checked the fuse box, checked no safety cut-outs stopping it from starting, All seemed OK.

I am wondering if there is a solenoid or relay gone, but not had any experience of an electric pto problem before...

Can anyone offer any suggestions to look at please? My auto sparky is unavailable at the moment... :-(

First question is what make and model

If it's new holland it's likely alternator also seen one with the speed selector in neutral

My Bad.

Its a Kioti EX50, Korean tractor. VERY similar to Kubota. Not a chinese cheapie

In fact all of the Jap/Korean tractors look as if they roll out of the same factory... Bit like cars really, all using the same suppliers for bits!

I can believe that... The manner in which the electricals are all controlled by a CPU which is then placed in a less than logical location bemuses me! The autoelectrician was telling me last year about a few tractors he has worked on. JD was a particular favourite.

You could Check the stop buttons on the mudgard by pass them with a little bit of wire one at a time and you find one could be faulty then replace I had similar problem

Cheers, not got a remote stop on this model.

Can u not get a live to the solinoid and see if it engages then. Could be good place to start

Good idea that...

I will have a root around a bit later and see if I can locate where the solenoid is positioned. I just hope it is external!!!

If powering the solenoid directly, make sure the pto brake is off. Learnt the hard way!

No PTO brake... as such as far as I am aware!

Think any initial testing will be done with the engine Off.

LGP Spreading BEFORE the problem

Wont be much weight in that wee yoke. All you need now is a slurry reeler hung back and front for wet fields

1.8t, more once I get in the cab! Ballast I call it....

Might need the upgraded 60hp version for that job ....

Ahhh electrical issues.... as you rightly indicate...

Hijacking the thread..... I have a JD6630 with a PTO that is playing up too... Is there a load sensors or something in the drive system? Pull the PTO switch up and it will sometimes choose not to engage, particularly at low revs, just flashes the PTO light on the dash.. If Iplay with the throttle and try the switch a few times eventually the drive engages. What is more annoying is when it chooses to disengage whilst fert spreading without any audible warning, did it once yesterday and once today... could do half the field without the discs spinning if I wasn't switched on to it! Have had it drop out turning hay and power harrowing too so seems to occur regardless of which PTO speed is selected. Any ideas?

Well, your're a Shropshire Lad, so come on in... even if the tractor is lowering the whole tone of the thread! ?

Sounds a bloody nightmare if the drive drops out.... nothing worse than a fert spreader doing that!!

i had soething similar on mf 6400 series was stop button on rear wings had failed would intermittently operate its self turn off pto.

Thanks Joe. It could well be something like that. I will try pressing the external buttons with the PTO running and see if that replicates the same effect of stopping the PTO and flashing the PTO light on the dash. The only thing that makes me question that being the issue is the PTO stopping mid work is still rare but the PTO failing to start is really common. If it was a external swtich fault I would have though it would be as likely to stop during work as be reluctant to start.
