PROBLEM TO BE SOLVED: To simplify mounting of a hydraulic pump 104 in a farm working machine and to reduce parts for power transmission.SOLUTION: The outer peripheral front side of a driving side pulley 21 is covered with a cover part 29b of a support body 29 used as a cover, with a base part 29a fastened to the side face of an engine 5 by a bolt 110, and a fixed sheave 25 is fixed to the inner surface of a tip support part 29c extending backward from the cover part 29b, while the hydraulic pump 104 is fixed to the outer surface. The tip of a boss part 25a of the fixed sheave 25 and an input shaft of the hydraulic pump 104 are detachably connected in series through a universal coupling means 105.COPYRIGHT: (C)2003,JPO【課題】 農作業機における油圧ポンプ104の取付けを簡単にし、且つ動力伝達のための部品も少なくする。【解決手段】 エンジン5の側面に基部29aをボルト110止めしたカバー兼用の支持体29のカバー部29bを駆動側プーリ21の外周の前面側を覆い、カバー部29bから後方に延びる先端支持部29cの内面に固定シーブ25を固定し、外面に油圧ポンプ104を固定する。固定シーブ25のボス部25aの先端と油圧ポンプ104の入力軸とを自在継手手段105を介して直列状、且つ着脱可能に連結する。
