PROBLEM TO BE SOLVED: To provide an agricultural implement having a means for increasing the rotational speed by obtaining part of the rotation power from a tractor, which is compact and excellent in the weight balance, and enabling to enhance the speed increasing ratio.SOLUTION: The agricultural implement 2 attached to the tractor 1 for the agricultural work includes: an input shaft 11 for receiving the rotation power from the tractor 1 and transmitting the power into a transmission case 114 first speed increasing means 13 and 15 for increasing the rotational speed by obtaining part of the power of the input shaft 11 second speed increasing means 17, 18 and 19 for further increasing the rotational speed increased by the first speed increasing means 13 and 15 and a power generator 20 for receiving the rotation whose speed is increased by the second speed increasing means 17, 18 and 19. The rotational frequency increased by the first speed increasing means 13, 15 and the second speed increasing means 17, 18 and 19 is at least three times as many as the rotational frequency of the input shaft 11.COPYRIGHT: (C)2012,JPO&INPIT【課題】トラクタからの回転動力の一部を得て回転を増速する手段が、コンパクトで重量バランスに優れており、かつ、増速比を高くすることができる農作業機を提供することを目的とする。【解決手段】トラクタ1に装着して農作業を行う農作業機2において、トラクタ1からの回転動力を受けてミッションケース114内に伝達する入力軸11と、入力軸11の動力の一部を得て回転を増速させる第1の増速手段13、15と、第1の増速手段13、15で増速した回転をさらに増速させる第2の増速手段17、18、19と、第2の増速手段17、18、19で増速した回転を受ける発電装置20とを有し、第1の増速手段13、15及び第2の増速手段17、18、19で増速される回転数は、入力軸11の回転数の3倍以上である。【選択図】図1
