フトアームの上下位置を油圧シリンダ内の圧力で
感知する感知装置を備えた農用トラクタにおいて
、リフトアームに引綱の一端を結着し、この引綱
の引き方向で油圧シリンダの加圧方向にリフトア
ームを回動させる引綱案内装置を備え、上記リフ
トアームの上下位置に対応した油圧シリンダ内の
圧力から引綱の引き度合いを報知する報知装置を
設けて構成したことを特徴とする農用トラクタを
利用した綱引き練習機。 In an agricultural tractor that is equipped with a hydraulic cylinder that drives the lift arm up and down and a sensing device that detects the vertical position of the lift arm using the pressure inside the hydraulic cylinder, one end of the tow rope is tied to the lift arm, and the hydraulic pressure is applied in the pulling direction of the tow rope. It is characterized by being equipped with a tow rope guide device that rotates the lift arm in the direction in which the cylinder is pressurized, and an alarm device that notifies the degree of pulling of the tow rope based on the pressure in the hydraulic cylinder corresponding to the vertical position of the lift arm. A tug-of-war training machine using an agricultural tractor.
