摘要
对进口的 ZT-323A 型大功率轮式拖拉机与国产东方红-75型履带式拖拉机的对比试验和计算分析表明,在京郊以旱地为主的农场,用 ZT-323A 取代东方红-75拖拉机在技术上和经济上是可行的,但在翻耕稻田时需要加装防滑装置。主要试验测定项目为发动机功率和油耗测定、田间牵引性能试验、生产查定和装防滑铁瓜翻耕稻地试验。
Through following tests,computation and analysis it is certified that using ZT-323A tractors,which imported from Democratic Germany,to replace Done Fang HonE-75 crawler tractor is feasible in technique and economic benefit in the state farms of Beijing,but if using it to plow paddy fields,antislip equipments are needed additionally.The test items are engine power and frel consumption,pulling performance in the fields, productive capacity measuring and recording in farming seasons,and ZT-323A plowing paddy fields with the antislip claws.
