The utility model discloses a cable tractor, including tractor, support, haulage rope, the tractor setting sets up a plurality ofly on the cable laying route at the terminal point of cable laying route, support, and the tractor includes take -up pulley, motor, and the rotation axis of take -up pulley is connected with the pivot of motor, and the haulage rope twines on the take -up pulley, and the length of haulage rope is greater than the length of cable laying route, the support includes support, leading wheel, and the leading wheel is installed at the top of support through the pivot, the free end of haulage rope pass in proper order behind each leading wheel with cable junction, cable ringing is on the cable drum, the rotation axis of take -up pulley passes through the coupling joint with the pivot of motor. Laying of cable is realized through regaining the haulage rope to the tractor, and the tractor is unmovable, has avoided the damage to plough or the problem of crop, through setting up the support, makes the cable break away from ground, greatly reduced the cable risk of wearing and tearing with dragging, reduced in the cable use risks such as the electric leakage that leads to the fact, cable explosion of breaking because of the crust.
