Imashini zihinga nka traktori cyangwa imashini zikata disiki zikoresha imiyoboro ya bevel, zimwe zikoresha imiyoboro ya bevel, izindi zikoresha imiyoboro ya bevel igororotse, izindi zikoresha imiyoboro ya bevel igororotse, izindi zikoresha imiyoboro ya bevel igororotse kandi izindi zikenera imiyoboro ya bevel igezweho. Ariko inyinshi mu miyoboro ya bevel zakoreshwaga mu mashini zihinga zari imiyoboro ya bevel ivanze, ubuziranenge bwa DIN8. Ariko ubusanzwe twakoreshaga icyuma gikozwe mu katoni gaciriritse, kugira ngo dukore carburizing kugira ngo duhuze ubukana bw'amenyo n'ubuso kuri 58-62HRC kugira ngo twongere ubuzima bw'ibikoresho.
