The crate on the back has a 3 gallon bucket that my chlorine tablets come in for my pool. Inside that bucket is ten 10lb plates out of my gym. In the 2nd video it was very slick out there. I didn't have any problem with the tractor slipping. The snow was kind of light, it wasn't the dense wet snow that is always a challenge no mater how you move it. I prefer my ballast removable that is why on both tractors you find it on the rear and not on the wheels. The clip in my signature is a different video than the one in the thread
