PROBLEM TO BE SOLVED: To provide a snow removal attachment for a construction machine which reduces hydraulic piping prepared on the arm side. SOLUTION: An auger and a blower are housed in a case body 11 attached to the arm 31 of the construction machine 3, and a shooter 14 is attached to the case body 11 of the snow removal attachment 1 for the construction machine. The shooter 14 is used for determining the discharging direction of snow from the case body 11. Then the snow removal attachment 1 for the construction machine is provided with a main hydraulic motor, a sub-hydraulic motor, and a selection circuit. The main hydraulic motor drives the auger and the blower, and the sub-hydraulic motor performs horizontal turning of the shooter 14. Then the selection circuit, which is connected to the feed piping and to the return piping of the arm 31, drives only the main hydraulic motor through the oil which is sent from the feed piping. Then the selection circuit drives only the sub-hydraulic motor through the oil which is sent from the return piping. COPYRIGHT: (C)2007,JPO&INPIT
