长期以来,由于小型拖拉机没有设计安装行驶牌照的位置,造成机手在购机之后将行驶牌照任意在机车上钻孔或穿挂铁丝乱悬乱挂,甚至有的机手将行驶牌照长期放在座垫下或工具箱内,常常出现断裂、丢失现象。总之,既不美观,又不利于农机监理部门统一管理。在湖南省农机监理处的指导下,桃源县农机化研究所研制出3种分别适应于东风-12、湖南-12及各种盘式小型拖拉机安装行驶牌照的悬挂支架,并于1990年12月27日通过省级技术鉴定。该悬挂支架设计合理,体积小、重量轻,安装方便,不损坏机车任何机件,且美观大方,工作可靠,均采用3毫米厚的扁铁裁
For a long time, since small tractors did not design a location for installing driving licenses, they would cause the drivers to drill holes or hang wire hanged on the locomotives arbitrarily after purchasing the aircraft. Even some of the drivers would leave driving licenses on the vehicle for a long time Under the cushion or in the toolbox, breakage and loss often occur. In short, it is neither beautiful nor conducive to the unified management of agricultural supervision departments. Under the guidance of Hunan Agricultural Machinery Supervision Office, Taoyuan County Institute of Agricultural Mechanization has developed three kinds of suspension brackets adapted to Dongfeng -12, Hunan -12 and various small disc tractor-mounted travel licenses, and in December 1990 27th passed the provincial technical appraisal. The hanging bracket design is reasonable, small size, light weight, easy installation, does not damage any parts of the locomotive, and beautiful and reliable, are used 3 mm thick flat iron cut
