The invention discloses a track vehicle walking and transmitting device which is capable of realizing continuous steering, convenient to control, applied to harvesting, planting, cultivating and sowing. The track vehicle walking and transmitting device comprises an input wheel driven by power. The track vehicle walking and transmitting device is characterized in that the input wheel is connected with a left hydraulic stepless speed changer and a right hydraulic stepless speed changer; the left hydraulic stepless speed changer is connected with a left driving wheel through a left transmission gear box; the right hydraulic stepless speed changer is connected with a right driving wheel through a right transmission gear box; the left hydraulic stepless speed changer and the right hydraulic stepless speed changer are controlled by a walking and steering control mechanism, so that the steering or the forward and backward moving of a track vehicle is realized. The track vehicle walking and transmitting device is simple in structure and convenient to control; a double-HST transmitting system structure is adopted, besides, a left driving speed-changing part and a right driving speed-changing part are independently arranged, so that the continuous steering can be realized, the failure rate of a speed-changing box is greatly decreased, the maintenance costs are reduced, and the walking and transmitting device can be applied to the track vehicle used for harvesting, planting, cultivating and sowing.
