Case MXU 135 Pto problem

[Alf]

The Pto stops after a few seconds . after about 6 trys I have to turn tractor off then back on to try again . Sounds electirrcal .any idea ?

Is your charging light out if it is change the bulb and if still not working it may be your alternator

 

[Alf]

The red light is out and it must be charging battery as it always starts .

 

[bazza3034]

Never mind that because mine started first bat but the bulb was fused and pto wouldn't work the brain needs nine volt s o r there abouts to tell them pto to come on

So did your pto start up then stop ?

Is there pto lights flashing

 

[Alf]

The yellow pto light comes on but then goes off as the pto stops

Is there pto lights flashing

 

[bazza3034]

Any green light flashing try the fuses and then the bulb all ways do they cheapest option first unfortunately i didn't talking from experience

 

[Alf]

No green lights flashing or any lights on that shouldnt . If the fuse was gone would it work at all ? I will check them . In my experance its never simple . Allways the expencive fix

 

[Alf]

I just phond an " expert " To be told it will be the solinoid that piuts it in gear . Apparently they give bother .

 

[Alf]

seems to have fixed itself for now

Sounds like the solinoid. Just done it on our NH 8360. When slurrying it would randomly cut out and after several tries restart a few mins later. When it cut out the yellow pto light went out and dash went back to showing lift arm height instead of pto speed

Where is solenoid ? I couldn't find it Found all the others under cab floor

the solenoid on my mx is down buy the pto, my pto light flashes all the time which is a pain but glows green when its on, the pto wont start unless you blip the revs when you engage the button, possibly solenoid?

PTO seems to be a problem on them

Mine is an MXU its dirrfrent from an Mx MXU is a N/H covered in Case plastic

I don't know, sorry. I wasn't around when mechanic came to it.

We had to do the 50k solenoid on ours not long ago and it was wheel and fuel tank off job, I think there was one marked PTO there as well but could be mistaken.

That doesn't surprise me . It could never have been simple .

The pto solenoid Is between the fuel tank and gearbox it can be changed without removing the wheel and tank but it is rather fiddly.
I changed the solenoid on my mxu at about 5000 hours,the symptoms I had sounds the same as yours so I'd have thought it's the problem. A new solenoid was about £200 and I changed it in an hour on the field.
One last simple thing to check would be the pto speed sensor wire. The Sensor is above the pto stub at the back of the tractor, the wire runs up the back beside the jaws for the top link.
The wire on mine had Chaffed through where the top link pin is, resulting in the pto engaging but only showing a few revs on the dash when At 540rpm,after a moment the tractor would realise the pto was not at the correct speed for the engine and disengage if you re engaged it it would be fine for an hour or two.
