First build ,cat D11

Hi Cooper
You have created one great machine for sure. I was a operator in a d10 for two years, and that dozer had a huge blade mounted on. I added a concrete block mounted on the ripper and tilted the blade backwards and when it started to fill up with dirt I lifted the blade slightly to don't dip down, the extra counter weight in the rear made the entire track surface stay in touch with the ground and ad traction. Your machine seems to have a lot of power so I think you can try to hang a weight temporary on the rear and see what happens.
Cool video
