I was pushing gravel out with the 299d and the front door just exploded. I spent 10 minutes looking for bullet holes inside the cab. I guess the cab must have tweaked in on it? I want to believe it was a crazy self levitating rock but the bucket was half full and the cab sits so high and far back compared to bobcats and other machines. anyone have this happen? And are there any good sources for replacement glass? Is oem better or all the same. I see aftermarket on eBay for $240.
