Langai, tractor ni a matu gat lawk ra kadawn ai lam hpe galai shai ai lam. Anhte a mungdan hta kaba ai hte lapran tsang-sized tractor ni a matu gat lawk gaw, shi ning jan na sai, madang tsaw ai hku galaw nga ai hpe yawng chye nga ai. Laksan hku nna, n-gun kaba hte lapran tsang n-gun n-gun n-gun hte shanhte a hkai lu hkai sha ai arung arai ni gaw wan 5.72 hte wan 8.94 du wa na re, 8.6% hte 8.1% shaning-on shaning jat wa na re. Dai rawt jat lam gaw, tractor kaji ni hte shanhte hte bung ai hkai sun arung arai ni hta tsa lam shadang 8 hte 7 daram tsaw ai. Grau kaba ai hte grau bung ai tractor ni a masa gaw grau dan dawng wa nga ai, tractor market a ra sharawng ai lam gaw shi a galai shai ai lam hpe lawan ladan galaw nga ai.
Lahkawng, gradient update gaw tractor ni a matu madung shadut ai n-gun byin wa sai. Shawng na quarter hta gat lawk a bungli galaw ai lam kaw nna, dai zawn dawdan na matu n yak ai: Miwa mungdan a tractor hpaga lam hta grai law hkra hkam sha ai lam a masa hta, tractor gat lawk a matu shadut ya ai n-gun gaw, madung hku nna, tractor kaba ni hte, tractor kaji ni hpe galai shai ai tractor ni hpe galai shai ai, n-gun kaba ni a kata na gradient update kaw na pru wa ai. Ndai update a madung manu gaw Miwa mungdan a tractor hpaga lam hpe gram lajang na matu n-gun jaw ai lam hta rai nga ai.
Masum, ndai shaning a shawng na mali ning laman hta langai hkrai a arawn alai ni hpe yu yang, lai wa sai shaning a shawng na mali ning laman hta, kaba ai hte lapran tsang n-gun n-gun n-gun jat ai tractor ni a matu gat lawk loi mi jat wa ai majaw re. Ndai shaning a shawng na mali ning laman hta, n-gun kaba ai platform hpe hpaw ninghtan ai gaw, gat lawk hta grai hkra machyi na re. Ndai gaw, kaba ai hte lapran tsang n-gun n-gun yawm wa ai de woi sa wa ai direct factor langai mi rai nga ai.
