山西芮城县城关镇农民马东亮自行设计,制作了一台小四轮联合收割机。此机形似佳联产大型联合收割机,但又稍有区别。驾驶台和集粮仓分置于两侧,发动机置于脱粒清选装置的腹下,割台采用后悬挂方式。该机割幅为1.4米,配套动力为8.8千瓦(12马力)。该机已试割小麦50余亩,效果不错。 Ma Ruiliang, a farmer from Chengguan Town, Ruicheng County, Shanxi Province, designed and produced a small four-wheel combine harvester. This machine is like a large joint production of large combine harvester, but a little different. The bridge and the grain silos are arranged on two sides. The engine is placed under the belly of the threshing and cleaning device. The header is suspended by the rear suspension. The machine cut width of 1.4 meters, supporting power of 8.8 kilowatts (12 horsepower). The machine has been cutting wheat more than 50 acres, the effect is good.
