OK, need some help, took the old tractor down to the lower field with a field master topper.
As I am topping, look back as I always do to check cutting and the topper looks like it's running on an angle, I lift the pto and it straightens up, lower, topping goes on an angle
Had a look and nothing obvious that I can see, the only thing I have differently is to run slightly higher cut, which I adjusted it for so it was still level.
At a loss and a quick google didn't bring anything up
Any help appreciated
