Be very careful with how much you fill the dump trailer, I overdid it a little with a 16T drum trailer full behind my 900. Tipped it, the muck stuck right at the back and next thing I knew was that I head butted the windscreen!!!
The weight was all behind the rear axle and it picked the 900 back end up about 4 foot, had to select diff lock and drive forwards and it came down really quick.
Will try and find the picture(i think I posted it before?)
