Does anyone have any experience of the M-Series graders cracking cab door windows..? We have had 4 or 5 to date over a 3-year period. Operator jumps down, closes the door, and the window cracks. A right pane in the ass because they are bonded windows and take time to replace and for the bonding to harden before the machine can go back to work again.
Obviously with the change from H to M the windows have gone from 2 smaller panes of glass to one large one and the door structure surely must have become weaker as a result. Certainly as far as I can see the door frame on the M series does not appear to be made from heavier material than the H to counter the removal of the bar in the centre of the door.
I'd be interested to hear if anyone else has had the same experience.
