Thread: Class ares 567 atz transmission problem

Hi all we have a class 567 with only 700 hrs on it that I drive at work,the problem is it won’t spin all 4 wheels when reversing up hill.when driving forward she will spin all 4 wheels but reverse won’t spin once you get over about 30-35 degrees slope,so you just stop and dig 2 holes with back tyres. Spoke to a dealer here in aus he said never seen or heard of it happening, we’ve got tractors with 10000 hrs pulling huge ploughs no issues. But that’s pulling not reversing up hill slashing or mulching.Tractor has a fel and 4in1 bucket or blade and root rake on so fairly heavy. Are any of you fellas working claas tractors in steep country and had or heard of this issue? Is there a safety or overload mechanism built in the transmission so you don’t overload drivetrain reversing? I’ve driven fiat,landini,mahindra etc tractors in steeper country doing same thing with no issues so the claas should be able to do it. Unfortunately it seems most claas tractors here in aus are only working flat dairy country or broad acre cropping country so the dealers may not have run into the issue but I thought maybe you fellas in nz may have. Thanks Steve

Sounds weird.

Screams electronics to me, as surely won't be a wear issue with such low hours.

Possibly ring a NZ Claas dealer operating in hill country over here and see if they have heard of this

Only thing I can think of from my experience, is that they seem to have two 4wd ‘modes’. Flick the switch and you’re in 4wd but it disengages automatically at hmm, 16 km/h from memory? May be more like 20, haven’t had much call for 4wd recently..

But if you hold the 4wd switch down for 5 seconds or so, it seems to lock in 4wd, and doesn’t disengage automatically at speed.

Probably not related to your issue, but could be worth a try.

I'd try a tractor in a darker shade of green

They are easy to find . . . Mostly within a small radius of the dealership or some sort of service truck . ...

Proof is in the pudding mate. Look at what all the contractors run, probably 10:1 JDs vs other brands and the guys that aren't running them are usually smaller operations hoping they can pinch a penny with some horrid red gear. I must say the euro guys know how to make the operator feel comfy, pretty nice interiors and fancy electrickery etc but when it's time to turn diesel into profit my loyalty will always lay very firmly in the green and gold camp.

I wonder if the cab tilting forwards isnt pulling on a wire or something?

Trace the wire from the 4X4 switch through the fuseboard and down to what actuates 4x4 on the trans is where I would look.Maybe even pop the switch out but keep it connected and then reverse up a slope,you could just be loosing continuity right there?

I have a Valtra tractor,complete with see through windows,interior seating,reciprocating windscreen wipers and circular steering wheel with rotational function.

Wow! thats one flash tractor you have there

Yeah I’m trying to get hold of the dealership in Tasmania as they are in hill country the other dealers in Australia all seem to be flat country,failing that nz might be the go,I was thinking wanaka but any recommendations?

I think it is a straight switch on or off but will try it.

Yeah it is possible, will be a nightmare getting at it under the cab

From experience here (with a different flavour of tractor, not all in same tractor); the 3rd one seems most likely

1. had a front diff partially go in one, would go in 4wd but would "slip" when doing certain things (shit your pants material pulling a feed wagon around in the wet)
2. as has been said before, dual switch for 'auto" 4wd, may apply for reverse but usually at a certain speed. Not sure about Claas but Fergusson have either a rocker type momentary switch to hold down or, in the more modern ones, two different buttons on the B pillar for auto or constant 4wd
3. back end oil, when you go nose down, oil runs to the front and can't be picked up by the pump. In quite a few of those tractors, oil flow is needed to keep the tractor in 4wd rather than just the change. This has caught me out a few times driving down a slope to retrieve something and then not being able to reverse out. It is probably worse if using oil flow for something else. I have found it helps to keep the back end over filled (on the dipstick) to avoid this.

As a side note for those saying get a JD, I think a lot of Claas tractors used JD engines

You're not by chance touching the brakes at all?

Some modes flick them into 2WD when a single brake is applied, or vice cersa, they engage 4WD when the brakes are applied.

Try touching the brakes while it's doing it if you're not already.

I vaguely remember a tractor I drove once that would flick into 2WD when the 3pt linkage was raised, it was setup for plowing so allowed a tight turn on the headlands when the implement was raised. Would've been a JD though.
