Nā pahi ʻoki disc disc mīkini mahiʻai, nā pahi ʻoki notched kaumaha, nā mea pono mīkini mahiʻai, kūpaʻa i ke kapa a paʻa

He mea pono kēia huahana no nā hana mahiʻai o kēia au, i hoʻohana nui ʻia no ka wāwahi ʻana i ka lepo ma hope o ka palau ʻana, ka hoʻopololei ʻana i ka ʻāina, ka weeding, ka hui ʻana i ka lepo a me ka mea hoʻouluulu, a me ka mulching i ka wā hoʻomākaukau ʻāina. Hana ʻia kā mākou mau pahi harrow me ka hoʻohana ʻana i ke kila kiʻekiʻe a me ka ʻenehana holomua. ʻO ko lākou kūpaʻa kūikawā i ka ʻaʻahu a me ka hopena, i hui pū ʻia me ka hana paʻa, e hoʻomaikaʻi nui i ka pono a me ka maikaʻi o ka mahiʻai ʻana, e lilo ia i koho kūpono no nā mahiʻai a me nā hui mahiʻai e hoʻokō ana i nā hana mahiʻai pololei a me ka mālama ʻana i ka mahiʻai.

1, ʻenehana: Me ka hoʻohana ʻana i ka ʻenehana lapaʻau wela holoʻokoʻa holomua (quenching + medium temperature tempering), hiki i ka paʻakikī o ka lihi o ka pahi harrow ke hiki i ka HRC 42-48, me ka mālama ʻana i ka paʻakikī maikaʻi o ke kumu, e ʻoi ai a kūpaʻa i ke komo ʻana a ʻaʻole maʻalahi e haki. Ua hoʻolōʻihi ʻia ke ola lawelawe ma mua o 30% i hoʻohālikelike ʻia me nā pahi harrow maʻamau.

2. Ma hope o ke kaʻina hana wela kūikawā, loaʻa i ka huahana ke kūpaʻa maikaʻi i ka luhi a me ke kūpaʻa i ka hopena me ka mālama ʻana i ka paʻakikī kiʻekiʻe. Hiki iā ia ke hoʻoponopono pono i nā wahi hana paʻakikī ma ke kula (e like me ke one a me nā poloka lepo paʻakikī) a pale i ka deformation a i ʻole ka haki ʻana i hoʻokumu ʻia e ka hopena.
