Chimodzi mwazovomerezeka zakale kwambiri za "macheka osatha" okhala ndi maulalo onyamula mano ocheka chinaperekedwa kwa Frederick L. Magaw wa ku Flatlands, New York mu 1883, mwachiwonekere ndi cholinga chopanga matabwa potambasula unyolo pakati pa ng'oma zopindika.Patent pambuyo pake yokhala ndi chimango chowongolera idaperekedwa kwa Samuel J. Bens waku San Francisco pa Januware 17, 1905, cholinga chake chinali kugwetsa matabwa a redwood.Makina oyamba onyamula makina adapangidwa ndikuvomerezedwa mu 1918 ndi wopanga mphero waku Canada James Shand.Atalola kuti ufulu wake ufooke mu 1930, zimene anatulukirazo zinapangidwanso ndi kampani ya ku Germany yotchedwa Festo mu 1933. Kampaniyi, yomwe panopa ikugwira ntchito monga Festool, imapanga zipangizo zamagetsi zonyamulika.Zina zofunika zothandizira pazitsulo zamakono ndi Joseph Buford Cox ndi Andreas Stihl;omalizawo anali ndi chilolezo ndipo adapanga makina opangira magetsi kuti agwiritsidwe ntchito pa malo opangira ma bucking mu 1926 ndi makina opangira mafuta mu 1929, ndipo adayambitsa kampani yowapanga mochuluka.Mu 1927, Emil Lerp, yemwe anayambitsa Dolmar, anapanga makina osindikizira oyamba padziko lonse opangidwa ndi mafuta a petulo ndi kuwapanga mochuluka.
Nkhondo Yachiŵiri Yapadziko Lonse inasokoneza kupereka kwa macheka a German ku North America, kotero opanga atsopano anatulukira, kuphatikizapo Industrial Engineering Ltd (IEL) mu 1939, wotsogola wa Pioneer Saws Ltd ndi gawo la Outboard Marine Corporation, yemwe amapanga makina akale kwambiri ku North. Amereka.
Mu 1944, Claude Poulan anali kuyang'anira akaidi a ku Germany akudula nkhuni ku East Texas.Poulan anagwiritsa ntchito chotchingira galimoto chakale ndikuchipanga kukhala chidutswa chopindika chomwe chimagwiritsidwa ntchito kuwongolera unyolo."Bow guide" tsopano analola kuti chainsaw igwiritsidwe ntchito ndi munthu mmodzi.
McCulloch ku North America anayamba kupanga makina osindikizira mu 1948. Zitsanzo zoyambirira zinali zolemera, zida za anthu awiri okhala ndi mipiringidzo yaitali.Nthawi zambiri, macheka a unyolo ankalemera kwambiri moti ankakhala ndi mawilo ngati magudumu.Zovala zina zimagwiritsa ntchito mizere yoyendetsedwa kuchokera pagawo lamagetsi lamawilo kuyendetsa kapamwamba.
Nkhondo yachiŵiri ya padziko lonse itatha, kukonza bwino kwa ma aluminiyamu ndi kamangidwe ka injini kunapeputsa macheka a unyolo moti munthu mmodzi akanatha kuwanyamulira.M’madera ena, ogwetsa ma tcheni ndi otsetsereka m’malo asinthidwa ndi odula mitengo ndi okolola.
Macheka ocheka matabwa aloŵa m’malo mwa macheka wamba opangidwa ndi anthu m’nkhalango.Amapangidwa mosiyanasiyana, kuyambira macheka amagetsi ang'onoang'ono omwe amagwiritsidwa ntchito kunyumba ndi m'munda, mpaka macheka akuluakulu "obaya matabwa".Mamembala a magulu ankhondo a injiniya amaphunzitsidwa kugwiritsa ntchito macheka a unyolo, monganso ozimitsa moto polimbana ndi moto wa m’nkhalango ndi kutulutsa mpweya woyaka moto.
Mitundu itatu ikuluikulu ya makina opangira ma chainsaw amagwiritsidwa ntchito: fayilo ya m'manja, makina opangira magetsi, ndi bar-mounted.
Makina oyamba opangira magetsi adapangidwa ndi Stihl mu 1926. Matcheni opangira zingwe adayamba kugulitsidwa kwa anthu kuyambira m'ma 1960 kupita mtsogolo, koma izi sizinali zopambana pazamalonda monga zida zakale zoyendera gasi chifukwa chakuchepa, kudalira kukhalapo kwa makina opangira magetsi. soketi yamagetsi, kuphatikiza chiwopsezo cha thanzi ndi chitetezo cha kuyandikira kwa tsamba ndi chingwe.
Kwa zaka zambiri zoyambirira za m'ma 2100 zopangira petulo zoyendetsedwa ndi petulo zidakhalabe zamtundu wodziwika bwino, koma adakumana ndi mpikisano wopangidwa ndi makina opangira ma lithiamu opanda waya kuyambira kumapeto kwa 2010s kupita mtsogolo.Ngakhale ma tcheni ambiri opanda zingwe ndi ang'onoang'ono komanso oyenera kudulira mipanda ndi maopaleshoni amitengo, Husqvarna ndi Stihl adayamba kupanga ma tcheni akulu akulu odulira mitengo koyambirira kwa 2020s.Makina oyendera mabatire akuyenera kuwona kuchuluka kwa msika ku California chifukwa cha ziletso za boma zomwe zidakonzedwa kuti ziyambe kugwira ntchito mu 2024 pazida zamagetsi zamagetsi zamagetsi.
