Ntchito zazikulu ndi mawonekedwe:

1. Kukolola:
- Mapesi a mbewu amadulidwa pogwiritsa ntchito mutu wakutsogolo (mpeni). Pamutu nthawi zambiri amakhala ndi tsamba lozungulira lomwe limatha kukolola bwino mbewu zautali wosiyanasiyana.

2. Kupuntha:
- Mbewu zodulidwa zimalowa m'malo opunthira, pomwe mbewu zimasiyanitsidwa ndi ngala kapena makoko ndi chopunthira. Kupunthirako kumatsimikizira kuti mbewuzo zisiyanitsidwe ndi zonyansa.

3. Kuyeretsa:
- Njere zopunthidwazo zimatsukidwanso ndi chofanizira ndi makina owonera kuti achotse udzu wotsalira, masamba, ndi zonyansa kuti mbewu zizikhala zoyera.

4. Kutsegula:
- Njere zotsukidwa zimatumizidwa ku ndowa kudzera mu njira yotumizira kuti ikasungidwe, ndipo pamapeto pake njereyo imatha kukwezedwa mugalimoto kapena chidebe china kudzera pa chipangizo chotsitsa.

5. Kuyendetsa ndi Kuwongolera:
- Zokolola zamakono zamakono zili ndi ma cab apamwamba ndi machitidwe owongolera, omwe amalola ogwira ntchito kuwongolera mosavuta ntchito zosiyanasiyana za chokolola, kuphatikizapo liwiro, kutalika kwa mutu ndi mphamvu yopunthira.

6. Mphamvu yamagetsi:
- Zokolola zophatikiza zili ndi injini zamphamvu zoperekera mphamvu zokwanira kuyendetsa machitidwe osiyanasiyana ndikuchita ntchito zosiyanasiyana. Mphamvu ndi luso la injini ndi zinthu zofunika kwambiri pozindikira momwe wokolola amagwirira ntchito.

7. Kusinthasintha:
- Zokolola zamakono zamakono nthawi zambiri zimakhala ndi mitu ndi ma adapter osinthika, omwe amatha kutengera mitundu yosiyanasiyana ya mbewu (monga tirigu, chimanga, soya, ndi zina zotero) ndi malo osiyanasiyana ogwira ntchito.
