    • A method of producing compounds in which the rubber phase contains a polyolefin and a halobutyl rubber, which is partially crosslinked, to which composition is then added additional polyolefin and a vulcanizable olefinic rubber, which is then further crosslinked using organic peroxides, and then blended with a styrenic rubber. The TPE compounds incorporate (A) polypropylene 10-90 weight parts (wt. pts.), (B) halobutyl rubber 90-10 wt. pts. (where (A)+(B)=100), (C) an olefinic rubber 10-120 wt. pts., (D) mineral oil softener 5-120 wt. pts., which are then treated thermally in the presence of (E) MOx and/or MCl, to which composition of 100 weight parts is added (F) polyolefin 100-600 wt. pts., and (G) a vulcanizable olefinic rubber 50-500 wt. pts. The resulting blend is then thermally treated with (H) organic peroxide(s), to which blend of 100 wt. pts. is then added and uniformly dispersed (I) 5-150 wt. pts. of styrenic rubber.The method produces thermoplastic elastomer compositions which can be molded into large parts with smooth surfaces that accept paint well, have a good balance of flexibility and strength.

    • The present invention provides a tractor in which necessity of maintenance of a precleaner can be checked without opening a bonnet every time. In a tractor in which the outside air which is purified through a precleaner is further purified through an air cleaner before the outside air is supplied to an engine, a radiator is arranged in front of the engine, the precleaner is arranged in front of the radiator, and the engine, the radiator and the precleaner are covered with a bonnet, the precleaner is arranged such that the interior of at least a dust collecting/storing portion of the precleaner is viewable from the outside in a see-through manner, and the bonnet includes a viewing portion through which the interior of the dust collecting/storing section is viewable.
    • 本发明提供一种拖拉机,其中可以在每次都不打开发动机罩的情况下检查必要的维护预清洗器。 在将外部空气供给发动机之前,通过预净化器净化的外部空气通过空气净化器进一步净化的拖拉机中,散热器布置在发动机前方,预排气器布置在散热器前面 发动机,散热器和预清洗器被罩盖盖住,预清洗器被布置成使得至少预清洗器的集尘/存储部分的内部可以以透视的方式从外部观看,并且 发动机罩包括观察部分,灰尘收集/收集部分的内部可通过该观察部分观察。
