Iyo vhiri doza inowanzo hombe pane inotevedzwa doza uye ine yakataura hydraulic steering uye inofamba pane diki axis.
Iyo crawler dozer ndiyo yakajairika dozer, inozivikanwa nemakwara ayo uye ripper kumashure.Nekuti chinokambaira (kana kuti track bulldozer) chine matinji, chinonyatso kuenderana nenzvimbo inoda kukweva (senzvimbo ine madhaka kana inotsvedza).
