The invention discloses a walking anti-deviation valve group of a skid loader, a hydraulic system and the skid loader. The walking anti-deviation valve group comprises an oil port x1-x4 used for detecting the walking state of the whole machine; the oil ports A1, B1, A2 and B2 are used for balancing the output pressure of the walking pump; an inlet of the shuttle valve I is connected with the oil ports x1 and x2, and an outlet of the shuttle valve I is connected with an oil port I of the reversing valve I; an inlet of the shuttle valve II is connected with the oil ports x3 and x4, and an outlet of the shuttle valve II is connected with a control oil port of the reversing valve I; an inlet of the shuttle valve III is connected with the oil ports A2 and B2, and an outlet of the shuttle valve III is connected with the oil port I of the reversing valve II; an inlet of the shuttle valve IV is connected with the oil ports A1 and B1, and an outlet of the shuttle valve IV is connected with an oil port II of the reversing valve II; a control oil port of the second reversing valve is connected with a third oil port of the first reversing valve. Under the condition that the original operation mode is not changed, the running working condition is automatically recognized, the pressure of the left and right walking motors is balanced, and the problem of linear running deviation caused by the load difference of the left and right wheel sides is solved.
