Well after 4 days of sweating in the french heatwave I with the brilliant help from Grapples and other members of this forum I have managed to get my old tractor working as it is supposed to ,the problem was a broken pin on the range lever which wasn’t allowing it to engage reverse it was a right bugger to get at as it was the inner lever and after hours wasted I tackled removing the hole assembly thanks again to Grapples .So it’s back together now and Can’t praise enough this great forum .Gotta add that fixing the old girl has been the highlight of my (Holiday)cheers Brian
