本研究係以國產野興牌YS 1300 型水稻聯合收穫機改良而成為高粱聯合收穫機，除可收穫高粱外，換下部分機件即可收穫水稻，反之亦然。本試驗機依據收穫高粱之試驗結果所顯示之缺點，分七個步驟改良完成。1. 提高機頭扶起裝置動力傳動橫軸，並拆除前閘門橫板，以允許較高高梁穗通過。2. 底部夾送鏈條與其夾導桿間之展開間隙加大，可讓較粗之株桿通過。3. 增長可調傾斜橫向夾送鏈總成長度，以調整高粱穗脫粒之適當位置。4. 改良可調傾斜橫向夾送鏈條與脫粒夾送鏈條間之轉接導桿，使株桿能順利進入脫粒夾送鏈。5. 增置導穗板，便利高粱穗部之導入脫粒室。6. 增加鼓風機迴轉數，提高風選能力。7. 增加回送管旋轉葉片迴轉數，增強擲送同脫粒室能力，避免同送管阻塞。
本試驗機已達可推廣使用階段，收穫高粱之作業能量為每日0.8~1.5 公頃（一日以8 小時計算），作業流量可達1,060 kgs / hr ，場地工作效率為78~82%，人工收穫高粱之費用每公頃約需7,500 元，用本機收穫所需費用每公頃約需5,500 元，則每公頃約可節省2,000 元，同時替代勞力20~25 人工次（man-day）。
An attempt was made in 1980 to modiyy and improve the locally made rice combine for harvesting sorghum grain. This Yeh-hsing YS 1300 rice combine has been modified or improved in seven steps to attain the aim, in accordance with the demerits exposed by the original combine which has been used to harvest sorghum.
The modified or improved components are: 1. Raise the power transmission transv-erse shaft 36 cm higher than the original position, and the front transverse gate plate was removed, so that it will alow the passing of sorghum heads. 2. Widen the open gap between the bottom gripping chain and guide rod to permit the passing of stalks, these stem diameters are larger than 1 .6 cm. 3. Elongate the inclined adjustable transverse gripping chain assembly for 25 cm, so it can be used to adjust he proper length of the stalk of sorghum head entering the thresher. 4. Improve the guide rod between the inclined adjustable transverse gripping chain and threshed gripping chain, this will alow the stalks to enter the threshed gripping chain easier. 5. Add guide plates to the blank side of the combine caused by lifting the transverse shaft support, for guiding sorghum heads into the threshing room. 6. Increase the fan speed to increase the blowing ability of dirts.7. Increase the speed of No. 2 auger with throwing back vanes in order to accelerate the ability of throwing material back to the threshing room.
This modiffied machine has reached the stage for commercially available at the present time, and has the abilityof sorghum harvesting capacity of 0.8 to 1.5 ha/day, grain flow capacity: 1,060kgs/ha, field efficiency: 78% to 82%. The sorghum harvest cost by human labor is N. T. $ 7,500/ha, and by this machine requires N. T. $5,500/ha, therefore it will save N. T. $ 2,000/ha, also it will take place the human Jaber labor of 20 to 25 man- days.
