Mu kinyejana cya 2 mbere ya Yesu, Ubushinwa bwari bumaze gukoresha imbaraga n’ingufu zitwa bamboo umuhengeri kugira ngo imyitozo ya conique igire ingaruka ku butaka kugira ngo ikore imyitozo ya percussion primitique, yari imaze igihe kinini ikoreshwa mu cyaro cy’Ubushinwa.Kugeza mu myaka ya za 1950, hashyizweho imyitozo y’umugozi w’insinga ziva mu mahanga, mu ntangiriro ya za 1960 zatangiye guteza imbere inkono nini, ntoya, ifata cone hamwe n’ubundi buryo bworoshye bwo gucukura.Mbere na nyuma ya 1966 batangiye guteza imbere imashini nziza yo kuzenguruka, mu 1974 mbere na nyuma yiterambere ryiza ryimashini ya dring rot rotine na mashini yo gucukura, impera za 70′s zakoze imashini yo gucukura.Uburayi na Amerika mu kinyejana cya 19, ikoreshwa ry’imyitozo ngororamubiri y’umugozi, mu myaka ya za 1860, Ubufaransa bwabanje gukoresha imyitozo ya rotary rotary, nyuma bwinjizwa muri Amerika kandi bugira iterambere ryihuse.Mu myaka ya za 1950, yatangiye guteza imbere imashini izenguruka imashini izenguruka, hanyuma igaragara hamwe n'umwuka ucogora aho kuba icyondo nk'imashini yoza iringaniza imashini icukura, kugeza mu myaka ya za 70 ikora imashini ya hydraulic power head rotary drine.
