Ibiti bizunguruka Ibiti bizunguruka bihuza na traktori

Gushyiraho no gushyiraho icyuma gihindura imiterere y’icyuma gihindura imiterere y’icyuma ni akazi gakomeye. Gushyiraho nabi bigira ingaruka zikomeye ku mikorere, kandi bitewe no kuzunguruka ku buryo budahuje kw’icyuma, bizangiza ibice no kongera ubwivumbure bw’icyuma, ibyo bikaba bidafite umutekano.

Uko intera iri hagati y’icyuma gikuraho ibyuma igenda ipfunyika mu butaka ni nini, ni byiza kwirinda kuziba. Mu gihe cyo kuzunguruka rimwe k’icyuma gikuraho ibyuma, ku nguni imwe y’icyiciro, icyuma gikuraho ibyuma kigomba kwinjizwa mu butaka kugira ngo gikomeze gukora neza kandi umutwaro w’icyuma gikuraho ibyuma ugere ku rugero rumwe. Iyo ibyuma birenga bibiri byashyizweho, ingano y’ubutaka bugomba kuba bungana, kugira ngo ubutaka busenyutse bugere ku bwiza kandi bugire umuyoboro woroshye nyuma yo guhinga.
