D11 bulldozer gets tested against some of our other machinery. The dozer is pulling them up a 4 degree slope and still does it fairly easily. The tractors were in neutral with brakes applied. Legend has it that D11's dont walk forward or backwards. They sit in one spot and the earth revolves under them when they turn their tracks. I think everyone will agree with me in saying the tractors and the dump truck should be pulling also to see how strong the Bulldozer is. There's some old footage of the Acco super dozer in a tug o'war with a Cat D10 along with 5 other smaller tracked dozers chained up with the D10. At first the Acco is pulled backwards but when the Acco brakes and begins to turn it's tracks forwards, it pulls them all backwards instead! The Acco could likely pull the D11 here and the machinery. Look I knew that none of them could even touch the dozer but the fact that the didn't even feel the need to tie to the frame of the dozer is funny they're like "yeah the implement will handle this no problem"
