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. 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 🙂
