The invention discloses a heading machine start traction method. The method comprises the following steps of paving start table rails on a work well ground and a tunnel ground, and lifting a heading machine to the start table rails; arranging at least one set of hoist group connected with the heading machine in front of the heading machine; starting the hoist group to drag the heading machine to move from a work well to a tunnel working face; after the front end surface of the heading machine is close to the tunnel working face, detaching the hoist group, arranging a reaction frame behind the heading machine, and arranging a negative ring pipe piece between the reaction frame and the tail end of the heading machine, so that the heading machine starts a negative ring until the heading machine completely reaches the tunnel working face. The method has the advantages that the hoist group draws and slides the heading machine to start, so that the workload that the heading machine starts the negative ring pipe piece can be reduced, while the construction cost is reduced, the start moving speed of the heading machine is greatly increased, and the construction period is shortened.
