The invention relates to a travelling transmission mechanism for a tracked vehicle. The mechanism is applied to agricultural mechanisms for tilling, harvesting, planting, seeding and the like. The mechanism comprises an engine (1), a clutch (3), a travelling turning control device (9) and a travelling driving wheel (10); a hydraulic pump, a hydraulic motor, a high-low pressure overflowing valve which forms a system are connected between the clutch (2) and the travelling turning control device (9) and mounted into a housing to form a closed-loop system; the hydraulic pump, the hydraulic motor and the high-low pressure overflowing valve are intercommunicated through integrated oil channels formed in the housing. According to the mechanism, the flow rate and flowing direction of hydraulic oil can be changed to achieve stepless speed variation and forward moving and backward moving; the power transmission structure is simple; the repair is convenient; the weight of the whole device can be reduced; the operation performance and travelling passing performance of the agricultural mechanisms can be improved.
