Zigawo za ulimi wozungulira, masamba a rotary tiller, masamba a rotary tiller

Chogwirira chozungulira ndi gawo lalikulu la makina a ulimi, opangidwira makamaka kulima nthaka. Chopangidwa ndi chitsulo chapamwamba cha 65Mn kapena chitsulo cha masika, chimazimitsidwa ndi kutenthedwa, zomwe zimapangitsa kuti chikhale cholimba cha HRC 45-50, kuphatikiza mphamvu yayikulu komanso kukana kuwonongeka. Kapangidwe ka tsamba lake lopindika (komwe kumapezeka m'makhonde ndi kumanja) kumathandiza kugawikana kwa nthaka bwino, ndi kuya kwa kulima kwa 15-25cm ndipo koyenera mathirakitala okhala ndi mphamvu ya 20-120 horsepower. Pamwamba pake pali galvanized ndi penti kuti chisagwe dzimbiri, ndipo chogwirira cha tsambacho chili ndi kapangidwe ka modular kuti chikhale chosavuta kusintha. Choyenera minda youma ndi ya mpunga, komanso ntchito zobwezeretsa udzu, chimapeza kuchuluka kwa kugawikana kwa nthaka kopitilira 85%, chimathandizira bwino kulowetsa mpweya m'nthaka, ndipo chimapeza kuwonjezeka kwa 30% mukugwira ntchito bwino poyerekeza ndi kulima kwachikhalidwe, zomwe zimapangitsa kuti chikhale chida chofunikira kwambiri paulimi wamakono wolondola.
