Magawo ophatikizira okolola ndiwo maziko omwe amathandizira kugwira ntchito bwino, kukhazikika komanso kwanthawi yayitali kwa makina onse. Gawo lirilonse limagwira ntchito yosasinthika pa nthawi yonse yokolola, yopuntha, kuyeretsa ndi kusonkhanitsa tirigu.

Magawo akuluakulu a chowunira chophatikizira amaphatikiza chamutu, chodulira, reel, ng'oma yopunthira, mbale ya concave, fan yoyeretsera, auger, tcheni cholumikizira, zonyamula, makina opangira ma hydraulic, magawo otumizira ndi masamba. Zigawozi ziyenera kukhala ndi mphamvu zambiri, kukana kuvala ndi kukhazikika kuti zigwirizane ndi ntchito ya nthawi yayitali, malo ovuta komanso nyengo zosiyanasiyana.

Zigawo zokolera bwino kwambiri zimatha kuchepetsa kulephera, kuwongolera magwiridwe antchito ndikuchepetsa mtengo wokonza. Kuvala zingwe monga ma blade, maunyolo ndi mayendedwe zimafunikira kuyang'aniridwa nthawi zonse ndikusintha kuti makinawo aziyenda bwino panthawi yokolola. Magawo okhazikika, odalirika komanso ofananira bwino amathandizira chophatikizira chokolola kuti chikwaniritse kutayika kochepa, kuchita bwino kwambiri komanso magwiridwe antchito apamwamba.

Pazaulimi zamakono, kuphatikiza zokolola sizimangokhala zowonjezera komanso chitsimikizo chofunikira chokolola chakudya. Mbali zabwino kwambiri zimapangitsa makinawa kukhala amphamvu kwambiri, amathandizira alimi kukulitsa zokolola, komanso kupereka chithandizo champhamvu pakukula kwaulimi komanso chitetezo cha chakudya.
