The present invention relates to a wheel shifter for an agricultural machine. According to the present invention, a width of a wheel is variable to suit a working condition even when the agricultural machine is stationary as well as moving. Therefore, work efficiency can be increased while crop damage is prevented, and user convenience can be increased. The wheel shifter for the agricultural machine of the present invention comprises: a frame having a resting plate at an upper part; a driving shaft installed in the transverse direction to a shaft housing fixed to both sides of the center of the bottom surface of the frame; left and right female spirals formed on both sides of an inner diameter of the driving shaft; a left drive shaft forming a left male spiral and a right drive shaft forming a right male spiral, which are coupled to both sides of the driving shaft; a driving means installed on the lower surface of the frame to forward and reverse rotate the driving shaft; and a wheel frame wherein front and rear wheels are attached to outside ends of the left and right drive shafts.

    본 발명은 농기계를 정지중인 상태는 물론 이동중인 상태에서도 바퀴를 작업지 여건에 맞게 폭을 가변시켜 농작물의 손상을 방지하면서도 작업 효율성을 높일 수 있고 이용자들의 편의성을 증대시킬 수 있도록 한 것으로서; 상부에 안치판을 가지는 프레임과; 상기 프레임의 저면 중앙 양측에 고정되는 축하우징에 횡방향으로 설치하는 원동축과; 상기 원동축의 내경 양측에 형성하는 좌암나선 및 우암나선과; 상기 원동축의 양측에 결합하는 좌수나선을 형성한 좌구동축 및 우수나선을 형성한 우구동축과; 상기 프레임 저면에 장착되어 원동축을 정,역 회전시키는 구동수단과; 상기 좌,우구동축의 외측단에 앞바퀴와 뒷바퀴를 장착한 바퀴프레임과 연결하여 구성하는 것이 특징이다.
