The invention discloses a crawler-type chassis for an agricultural machine. A left annular crawler structure and a right annular crawler structure are respectively connected to two sides of a chassis rack, wherein each of the left annular crawler structure and the right annular crawler structure comprises an annular crawler; a driven wheel set which consists of a front pulley, a rear pulley, bottom pulleys and two top pulleys is arranged in each annular crawler, and the top pulleys are positioned at the top of the inner side of each annular crawler and support each annular crawler upwards; a driving wheel is arranged at the top of the outer side of each annular crawler in a meshing manner, and the driving wheel is positioned between supporting positions of the two top pulleys and compresses the annular crawler from top to bottom, so that a circular arc is formed at the top of each annular crawler, and requirements for the transmission wrap angle of external teeth of the driving wheel are met; two support legs are respectively arranged on two sides of the chassis rack so as to support the two top pulleys of the left annular crawler structure and the two top pulleys of the right annular crawler structure; when the height of the support legs is adjusted, the height of the chassis rack above the ground can be adjusted; a speed change gear box is arranged between the left annular crawler structure and the right annular crawler structure; output shafts of the speed change gear box are respectively connected with the driving wheel of the left annular crawler structure and the driving wheel of the right annular crawler structure. The agricultural machine with the crawler-type chassis can turn by 90 degrees in situ or turn round by 180 degrees in situ.
