  OPERATOR OF THE YEAR  BELIEVABLE BUT VERY DIFFICULT

A bulldozer is a crawler (caterpillar tracked tractor)or wheels, equipped with a substantial metal plate (known as a blade) used to push large quantities of soil, sand, rubble, etc., during construction work and typically equipped at the rear with a claw-like device (known as a ripper) to loosen densely-compacted materials pull big stones or act as root extractor . The term “bulldozer” is often used to mean any heavy equipment (sometimes a loader and sometimes an excavator), but precisely, the term refers only to a tractor (usually tracked) fitted with a dozer blade. That is the meaning used here.
