摘要：
The present invention relates to an agricultural machine having various functions by an operation of a braking pedal. The agricultural machine comprises: a main shift lever (10) which is operated by a user； a potentiometer (12) which senses an operating direction and an operating amount of the main shift lever； a braking pedal (23) for braking； a limit switch (23b) which senses an operation of the braking pedal； an electric controlling unit (20) for operating an engine rev count of the agricultural machine and output of HST； and a controlling unit (50) which controls the electric controlling unit based on a sensing signal of the potentiometer. The electric controlling unit includes a driving motor (22)； a sector gear (24)； an HST connecting rod (26)； a cam member (30)； and a throttle lever (28). The sector gear (24) is operated by the driving motor, and is installed in a base to be able to rotate. The HST connecting rod (26) is connected to the sector gear and operates a swash plate of the HST by rotation of the sector gear. The cam member (30) is connected to the sector gear and includes a forward cam curved surface and a backward cam curved surface. The throttle lever (28) allows a lower roller to touch the forward cam curved surface and the backward cam curved surface, is rotated in the base through a center shaft, and allows an upper end unit to be connected to a throttle cable (Wa) for increasing the rev count of the engine. The controlling unit controls the HST to be a neutral state and controls an engine to be in an idle state with a sensing signal of the limit switch of the braking pedal.본 발명은 제동페달의 조작으로 다양한 기능을 가지는 농기계를 제안한다. 본 발명 농기계는, 사용자가 조작하기 위한 주변속레버(10), 상기 주변속레버의 조작 방향 및 조작량을 감지하기 위한 포텐셔미터(12), 제동을 위한 제동페달(23), 제동페달의 작동 여부를 감지하기 위한 리미트스위치(23b), 농기계의 엔진 회전수 조작 및 HST의 출력 조작을 위한 전동제어유닛(20), 그리고 상기 포텐셔미터의 감지 신호에 기초하여 전동제어유닛을 제어하기 위한 제어부(50)를 포함한다. 전동제어유닛은, 구동모터(22)와, 상기 구동모터에 의하여 작동되고 베이스에 회동 가능하게 설치되는 섹터기어(24), 상기 섹터기어와 연결되어 섹터기어의 회전에 따라서 HST의 사판을 조작하는
