Bulldozers ifise ivyuma (nk’ugushirako amapantalo) ifise ukuboko kw’ibikorwa nk’imiterere y’ugushigikira ataco ihinduye ku ndobo:
Ingingo ngenderwako y'akazi: Igipande c'imbere kiragwira kandi kigasubira inyuma kugira ngo kitware ukuboko kw'akazi kugira ngo kiduze no hasi, kigatuma indobo iheza uruziga rw'"uguterera kw'ubutaka → gutera hejuru → guhinduranya umuzigo". Uburebure n’umwanya w’ukuboko kw’ukuboko kw’akazi ni vyo bigena uburebure bwo gukora n’ugukuraho umurongo w’indobo. Nk’akarorero, igihe umuntu ariko arakura mu mine, amaboko maremare akora arashobora gukuraho ibikoresho ku modoka zitwara abantu benshi.
Ihinduka ry’imiterere: Ukuboko kw’ibibindi akenshi bikoreshwa nk’igice kimwe canke bibiri (igice ca kabiri gishobora gupfungwa kugira ngo kigabanye ubunini bw’ugutwara), kandi inkomezi z’ukuboko zikeneye guhura n’ubushobozi bw’indobo (akenshi 3-10m 3) kugira ngo ntizigire ico zihinduye mu gihe co gushiramwo ibintu bikomeye.
Ivyiyumviro: gushiramwo ibintu no gutwara abantu mu buhinga bwo gukora kw’isi, gukoresha ubuhinga bwo gucukura ibikoresho mu gihe gito, gukoranya ibikoresho mu gihe co gutsimbataza aho hantu, n’ibindi.

Ukuboko kw’ikigega kinini c’amabuye y’agaciro gashobora guhindurwa n’igikoresho co kubohora ubutaka bukomeye, ubutaka bukonje, n’urutare rw’ikirere:
Ingingo ngenderwako y’akazi: ukuboko gukora ni kwo kugenzura imfuruka y’injira y’ubutaka n’uburebure bw’igikoresho co kurekura ubutaka biciye mu gitereko c’amavuta. Inyuma y’aho ubutaka bubohore amenyo bukorana n’isi, ukuboko kw’ibikorwa biratwara inguvu z’ugusesagura, bihindura igihimba c’umubiri c’amavuta kikagira inguvu zo kwinjira ubutaka mu buryo buhagaze, kandi kigashika ku guca ibice kw’ivu.
Ibiranga imiterere: Ukuboko kw’igikoresho co kubohora ubutaka akenshi ni ngufi kandi gukomeye, n’ukwiyongera kw’uburemere bw’ukuboko kw’ibice 20% gushika kuri 30%. Ivyo gutera ivyuma bifise ubushobozi bwo guhangana n’ibintu bikomeye (bibereye ku ngaruka nyinshi- Ingaruka z’incuro), kandi intebe y’ihuriro ry’amavuta irakomezwa kugira ngo ishobore kwihanganira inguvu nyinshi z’umurongo.
Ivyiyumviro vy’ugusaba: Guca mu nzira y’amazi imbere y’ubwubatsi bw’inzira, gukuraho ubutaka bwo hejuru mu binogo, n’uguca ibice bikomeye vy’ubutaka mu gusanura ubutaka bwo mu mirima.
