Benjamin Holt, onye Amerịka, mepụtara Crawler dozer (nke a makwaara dị ka crawler dozer) nke ọma na 1904. E wuru ya site na itinye bulldozer ebuli aka n'ihu traktọ crawler. N'oge ahụ, ike ahụ bụ injin steam. Mgbe e mesịrị, e mepụtara crawler dozers nke ike gas na injin petrol na-anya. E mekwara agụba bulldozer site na ibuli aka gaa na ibuli waya. Benjamin Holt bụkwa otu n'ime ndị guzobere Caterpillar Inc. na United States. Na 1925, Holt Manufacturing Company na C 50. Best Bulldozer Company jikọtara ọnụ wee mepụta Caterpillar Bulldozer Company, wee bụrụ onye mbụ na-emepụta ngwa bulldozer n'ụwa, ma wepụta otu mbụ nke bulldozer 60 nwere injin dizel na 1931. Site na ọganihu na-aga n'ihu nke teknụzụ, injin dizel na-arụ ọrụ bulldozer, a na-ejikwa silinda hydraulic ebuli agụba bulldozer na scarifier niile. Na mgbakwunye na bulldozer ụdị crawler, enwere bulldozer ụdị taya, nke dị ihe dị ka afọ iri karịa bulldozer ụdị crawler. Bulldozer crawler nwere arụmọrụ njikọta ka mma ma nwee ike ịrụ ọrụ nke ọma, yabụ ụdị na ọnụọgụ nke ngwaahịa ha n'ụlọ na mba ofesi karịrị nke bulldozer taya. N'ụwa niile, Caterpillar bụ ụlọ ọrụ mmepụta igwe injinia kachasị ukwuu n'ụwa. Bulldozer caterpillar ya gụnyere nnukwu, ọkara na obere usoro D3-D11, D11 RCD kachasị ukwuu, ike flywheel nke injin dizel ruru 634kw; Komatsu, ụlọ ọrụ Japan, nọ n'ọkwa nke abụọ. Na 1947, ọ malitere iwebata ma mepụta bulldozer crawler D50. E nwere usoro 13 nke crawler bulldozers, site na D21-D575, nke kacha nta bụ D21, ike flywheel nke injin dizel bụ 29.5kw, nke kachasị ukwuu bụ D575A-3SD, ike flywheel nke injin dizel bụ 858kw. Ọ bụkwa bulldozer kachasị ukwuu n'ụwa ugbu a; Onye ọzọ na-emepụta bulldozer pụrụ iche bụ Liebheer Group nke Germany. Ndị bulldozers ha niile na-arụ ọrụ site na nrụgide hydrostatic. Mgbe ihe karịrị afọ iri nke nyocha na mmepe gasịrị, teknụzụ a webatara ihe nlereanya na 1972. Na 1974, ọ malitere imepụta PR721-PR731 na PR741 hydrostatic crawler bulldozers. N'ihi oke nke ihe ndị mejupụtara hydraulic, ike kachasị ya bụ naanị 295Kw, ụdị ya bụkwa PR751 mining.
