I am a dozer owner & operator. One of the critical mistake i see with new operators is running the machine hard and then just put it park and kill the machine without letting idle for a few minutes. This mistake burns the seals in the turbo and subsequently fries the engine.The best advice I ever got on a dozer was all the work is done in the seat of the machine. You can feel yourself slipping forward in the seat pull up, if you feel like you are getting pulled back push down. Same thing for side to side.
