Likarolo tsa mechini ea temo: mahare a rotary tiller, a teteaneng, a thatafetse, a hana ho tsofala, 'me a hanela ho kobeha.

Mahare a ho lema a potolohang ke dikarolo tsa mantlha, tse kgathatsehang habonolo tsa mochini o potolohang. Ha a hokahantswe le shaft ya ho tlosa matla ya terekere, a potoloha ka lebelo le phahameng ho seha mobu, a fihlella tshebetso e kopaneng ya ho roba mobu, ho tlosa dikutu le ho lekanyetsa mobu. Jwalo ka karolo e thusang e sebediswang haholo mechining ya ho lokisa mobu, boleng ba yona bo laola ka ho toba bokgoni le ditjeo tsa mesebetsi ya masimo.

Letoto lena la di-rotary tillers le sebedisa tshepe e matla ya alloy (jwalo ka 60Si2Mn) e le thepa ya motheo mme e etswa ka ho etsa die forging ho netefatsa hore lehare le na le lehare le lengata mme ha ho na tshenyo e patehileng. Ha re sebetsana le dibopeho tsa ho kgohlana ha mobu, re sebedisa mokgwa o tswetseng pele wa kalafo ya mocheso: kamora ho tima letsoai ka botlalo, e futhumatswa mochesong o itseng, e fihlella thata ya lehare ya 55-60 HRC, ha mohele o boloka matla a hoo e ka bang 45 HRC, o etsa sebopeho sa "thata ka ntle, se thata ka hare" se hanelang ho tsofala le ho robeha.
