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
