PROBLEM TO BE SOLVED: To provide farm equipment which enables regulation of switching to a backward motion of a transmission mechanism by a gear shift lever and regulation of switching to a forward motion and a high speed to be performed during high-speed power transmission, in the state of selection of a high-speed-side clutch from high-speed-side and low-speed-side clutches, which makes operability proper in that case, and which enables the regulation to be performed at a low cost.SOLUTION: A high-speed-side clutch and a backward-motion-side regulation member 38 are mechanically associated with each other by a linkage mechanism 43 so that the backward-motion-side regulation member 38 can operate to be switched to an action attitude when the high-speed-side clutch is operated to be connected. The backward-motion-side regulation member 38 is supported on the side of a high-speed-side regulation member 29 so that regulation of a backward-motion operation by the backward-motion-side regulation member 38 in the action attitude can be concurrently performed by making the high-speed-side regulation member 29 regulate a high-speed operation.SELECTED DRAWING: Figure 7
【課題】高速側クラッチ及び低速側クラッチのうち、高速側クラッチが選択され、高速動力が伝動されている最中は、変速レバーによる変速機構の後進への切換の規制及び前進高速への切換の規制を行うことが可能であり、その際の操作性が良好で、且つ安価なコストで規制が可能な農作業機を提供することを課題とする。【解決手段】高速側クラッチを接続作動させた場合に後進側規制部材38が作用姿勢に切換作動するように、該高速側クラッチと後進側規制部材38とを連係機構43によって機械的に連係し、高速側規制部材29によって高速操作を規制させることにより、作用姿勢の後進側規制部材38による後進操作の規制が併せて行われるように、該後進側規制部材38を、前記高速側規制部材29側に支持する。【選択図】図7
