Posachedwapa, mtundu watsopano watsamba lozungulira la chogwirirayakopa chidwi chachikulu m'munda wa makina a zaulimi. Tsambali limagwiritsa ntchito zipangizo zatsopano komanso kapangidwe kake, zomwe zimapangitsa kuti ulimi ugwire bwino ntchito komanso kuti ukhale nthawi yayitali, komanso limapereka chithandizo champhamvu chaukadaulo pakukula kwa ulimi wamakono.
Masamba achikhalidwe ozungulira amatha kusweka akagwiritsidwa ntchito, ndipo amadya mphamvu zambiri. Masamba atsopanowa amawongolera mawonekedwe ndi kapangidwe ka tsamba kuti achepetse kukana kwa nthaka ndikuchepetsa kugwiritsa ntchito mafuta ndi pafupifupi 15%-20%. Kapangidwe kake kapadera kopindika ndi m'mphepete mwa tsamba kumatha kudula nthaka yolimba mosavuta, kuphwanya nthaka mofanana, ndikukweza kwambiri mtundu wa ulimi.
Masamba atsopanowa amapangidwa ndi chitsulo champhamvu kwambiri ndipo agwiritsidwa ntchito mwapadera pochiza kutentha, zomwe zimapangitsa kuti kukana kuwonongeka kukhale kolimba komanso kukana kugwedezeka. Deta yoyesera ikuwonetsa kuti pansi pa mikhalidwe yomweyi yogwirira ntchito, nthawi ya masamba atsopano imakhala yayitali kuposa 30% kuposa ya masamba achikhalidwe, zomwe zimachepetsa ndalama zosinthira ndi nthawi yopuma ya alimi, ndipo ndi yoyenera kwambiri pantchito zazikulu zaulimi.
Masambawa amapezeka m'njira zosiyanasiyana za mitundu yosiyanasiyana ya nthaka, kuphatikizapo mitundu yapadera ya dongo, mchenga ndi nthaka yosakanikirana. Kapangidwe kake ka modular kamapangitsa kuti kusintha kukhale kosavuta, ndipo alimi amatha kusintha mosavuta malinga ndi zosowa zenizeni kuti atsimikizire zotsatira zabwino zaulimi.
Pamene kuchuluka kwa makina a ulimi kukupitirirabe kusintha padziko lonse lapansi, makina a ulimi ogwira ntchito bwino komanso osawononga mphamvu akhala chizolowezi chamakampani. Tsamba latsopano la rotary tiller silimangowonjezera magwiridwe antchito, komanso limachepetsa kuwononga mphamvu ndi mpweya woipa, zomwe zikugwirizana ndi lingaliro la chitukuko chokhazikika cha ulimi. Ndemanga kuchokera kwa alimi zikusonyeza kuti mutagwiritsa ntchito tsamba ili, mtengo wa ulimi pa ekala imodzi ukhoza kuchepetsedwa ndi 10%-15%, ndi phindu lalikulu pazachuma.
Pakadali pano, mankhwalawa akwezedwa ndi kuyesedwa m'maboma ambiri akuluakulu a ulimi ku China, ndikutumizidwa ku Southeast Asia, Africa ndi madera ena, ndipo alemekezedwa kwambiri. Makampani oyenerera adati apitiliza kukonza bwino magwiridwe antchito a malonda mtsogolo, kulimbikitsa kuphatikiza ukadaulo wanzeru wowunikira ndi masamba, ndikupititsa patsogolo kuchuluka kwa makina a ulimi.
Akatswiri adanenanso kuti ngakhale kuti masamba a rotary tillers ndi ang'onoang'ono, ndi zinthu zofunika kwambiri zomwe zimakhudza bwino ulimi. Kapangidwe katsopano kameneka sikuti kamangothetsa mavuto a masamba achikhalidwe okha, komanso kamayala maziko a chitukuko cha ulimi wanzeru. Ndi kupita patsogolo kosalekeza kwa ukadaulo, makina aulimi ogwira ntchito bwino komanso olimba adzakhala mphamvu yofunika kwambiri pakulimbikitsa kusintha kwa ulimi.
