Zvikamu zvemichina yekurima: 65Mn simbi inogadziriswa kupisa uye isingaparare yemapuranga erotary tillers.
Chidimbu chemuti wekurima chinoshandiswa zvakanyanya mukugadzira kwekurima kwemazuva ano. Chinoshandiswa zvakanyanya nematractor, chinoshandiswa zvakanyanya pamwe chete nema rotary tillers, michina yekurima, uye vanodyara mbeu vasingarimi. Chigadzirwa ichi chakagadzirirwa ivhu rakaoma uye chinhu chikuru chekubvisa mashanga, kubvisa masora, kubvisa matombo, kusunungura ivhu. Kugadzirwa kwaro kwakasimba kunocheka ivhu rakaoma, kuchicheka midzi yepasi pevhu uye kugadzira nzvimbo yakachena uye yakasununguka yekudyara mbeu.
Mapanga aya akatevedzana akakamurwa kuita mafomu maviri: C-type neL-type. Ose akagadzirwa achishandisa nzira yekuumba, zvichiita kuti simbi ive yakakora uye isina maburi ejecha, ine simba guru rekudzivirira uye kusimba. Muviri webanga une zvikamu zviviri: mubato nemusoro webanga. Mubato une maburi ekugadzirisa akagadzirwa nemazvo kuti uve nechokwadi chekuti blade shaft inoiswa zvakanaka; musoro webanga une mupendero wekucheka wakabatana uye mupendero wekucheka wepadivi, nemipendero yacho yakasimbiswa kaviri uye yakapetwa, zvichiita kuti ive yakapinza uye isingapfeki.
Kuti ikwanise kutsungirira kukweshana kwevhu kwakasimba uye kurohwa nematombo, chigadzirwa ichi chinogadzirwa nesimbi dzesimbi dzakasimba dzesimbi dzakadai se60Si2Mn, 60Si2MnA, uye 28MnSiB. Maitiro ekurapa kupisa epamusoro anoita kuti kuoma kwebanga kudzorwe pakati peHRC 42 ne48. Izvi hazvingovimbisi chete hunhu hwakanaka hwekuzvirodza (kuchengetedza mupendero wakapinza panguva yekushandiswa) asiwo zvinoita kuti banga rive rakasimba zvakakwana kudzivirira kutyoka panguva yekushanda.
Muviri webanga une dhizaini yakakotamira yakagadzirwa zvakanaka (arc inokombama inosvika 120°), iyo inoderedza zvakanyanya kusimba kwesimbi kana ichichekwa muvhu, zvichideredza kushandiswa kwesimba retractor nokudaro zvichichengetedza simba. Panguva imwe chete, kureba kwebanga rakachekwa zvakanaka padivi kunoita kuti kurimwa kurambe kwakadzikama kunyangwe mushure mekusakara kwebanga, zvichiwedzera nguva yekutsiva.
Chigadzirwa ichi hachingokodzeri chete pakugadzirisa nekudzura minda yekurima, asiwo chinoshanda zvakanaka mukugadzira matombo, kupwanya mashanga, kubvisa mashanga, uye kusadyara mbeu. Kana chikashandiswa pamwe chete nebanga risingarimi, chinopwanya mashanga epamusoro nemashizha, zvichiita kuti mashanga adzokere mumunda uye kuwedzera huwandu hwezvinhu zvakasikwa muvhu.
