My dream dozer would be a Komatsu D85ex-15 which may be a little big but you can do small jobs as well as large one. Would be fitted with a air cab, heavy duty cannopy and cab guarding and sweeps, bull tilt blade with tree pusher. Would have a komatsu winch because they pull well and are built heavy. Anyway Dads knows someone who has owned a few dozers and the komatsu D85ex is the best machine he has ever had. He has owns a Komatsu D60E-8 like dads which has been teriffic machine for Dad. 2x Komatsu D65EX-15, owned a Cat D7G and not sure what else.
