I have spent a couple of hours adjusting the arms and blades today.
It is impossible to stop thr blades going over the windscreen frame. I have the parked position adjusted so that the blades rest right up to the frame, they still go over the frame by about 1/2" on the other side of the sweep.
To stop this shorter blades would be required, the stock blades are approximately 7" long, should be nearer 6 1/2".
Everyone with a late model must have the same problem.
Any thoughts on trying to commission some shorter blades?
