NH T6 4WD issue

[jamesy]

Having an issue with 4WD on my T6.155, currently sowing with combi dril/front fert tank. 4WD doesn’t seem to work correctly.
It comes on as I can feel the difference when travelling if I switch it off then on again, but, when I come to a damp spot and the going gets tough the 4WD seems to up sticks & bugger off. All 4WD lights come on & I changed the collar on shaft thinking it might be it worn - which it was but made no difference. Any ideas? Local NH guy was out today & plugged in laptop and found no issues

is that with it on the Auto setting?

You’ve obviously never seen my sowing! No auto steer

I lost a fair bit of trans oil when feed pipe to front fan went. Didn’t have enough oil to fill it right up, would that effect the 4WD?

I mean the Auto 4wd setting, or 4wd on full time. I've never had much luck with it on auto. never there when you need it

 

[jamesy]

Ah, I get you. It’s the same in both… I never tend to use the auto function either.
Anyway, I’m sowing last field one way to get it done then a trip to the dealer for it will hopefully solve the problem!

I am having a similar problem with a T6020, the mechanic recons its either a faulty solenoid or the pressure plates. It's booked in next week for him to get a proper look.

Normally if there is an issue most machines tend to switch on 4wd as a safety feature not switch it off. It normally takes pressure to knock it out rather than switch it on.

Must be some sort of clutch pack giving in. They grip to a certain degree but when really need gives up

 

[jamesy]

Sowing one way is somewhat tedious

Could there be some interesting tramlines?

Hope not, as I didn’t even have the control box plugged in!

Certainly on our TM the default fail puts it into 4wd, can't see it would be different in the T series, never had our T6070 have a fuse blow or other fail to know.
