我场每年种植青贮玉米1万多亩,以满足5000多头奶牛的饲草需求。每年收获正逢雨季,E281青贮收获机很难进行作业,只能靠人工割倒定点抱铺粉碎,造成劳力紧张,收获期延长。为此我们于1987年将原机改装了防陷半链轨,经过两年使用证明改装是可行的。 Each year I plant more than 10,000 mu of silage corn to meet the forage demand of more than 5,000 cows. The annual harvest is coincided with the rainy season, E281 silage harvester is difficult to operate, only by artificial cut-point hold shop smashing, resulting in labor stress, harvest period extended. To this end, we modified the original machine in 1987, half-rail anti-roll rail, after two years of use that modification is feasible.
