Since it is arranged close to the inside of the unit 49, the pulling input vertical case 39 (the pulling input vertical axis 39a) is positioned closer to the inside than the left end of the pulling input horizontal case 40 (the pulling input horizontal axis 40a). Connected. Therefore, the speed change case 39b provided in the pulling input vertical case 39 is also disposed at a position inside the left end portion of the pulling input horizontal case 40 (the pulling input horizontal shaft 40a). As a result, a space for arranging the light cover 83 can be secured in the vicinity of the left end portion of the pulling input lateral case 40 without being obstructed by the speed change case 39b or the like. Of course, since the vicinity of the right end portion of the pulling input horizontal case 40 is away from the connecting portion of the pulling input vertical case 39, a space for arranging the light cover 83 can be secured.

  Further, the cutting device 3 includes a pulling case 42 of the pulling mechanism and a pulling input lateral case 40 that supports the upper end side of the pulling case 42, and a direction indicator lamp reflector 90 is provided on the side end side of the pulling input horizontal case 40. A direction indicator lamp 84 is provided on the mounting / direction indicator lamp reflector 90. Since the pulling input side case 40 is configured to be highly rigid so as to support the upper end side of the pulling case 42, a direction indicator lamp reflector 90 is attached to the side end side of the pulling input side case 40, and this direction indicator lamp By providing the reflector 90, the direction indicator lamp 84 can be supported with high rigidity. Therefore, even if vibration or the like is applied to the direction indicator lamp reflector 90 due to traveling of the traveling machine body, it is possible to suppress the inconvenience that the attachment of the direction indicator lamp reflector 90 is loosened. In addition, you may comprise so that the direction indicator lamp reflector 90 may be attached to the pulling input vertical case 39. FIG.

  Further, a headlamp reflector 88 is attached to the side end portion side of the pulling input side case 40, and the headlamp 81 is provided on the headlamp reflector 88. Since the pulling input lateral case 40 is configured to be highly rigid so as to support the upper end side of the pulling case 42, a headlight reflector 88 is attached to the side end side of the pulling input lateral case 40. By providing the reflector 88, the headlamp 81 can be supported with high rigidity. Therefore, even if vibration or the like is applied to the headlight reflector 88 due to traveling of the traveling machine body, it is possible to suppress the disadvantage that the attachment of the headlight reflector 88 is loosened. The headlight reflector 88 may be attached to the pulling input vertical case 39.

  Further, the left and right light covers 83R and 83L form an upper side cover that covers the left and right sides of the pulling input side case 40, and the headlamp 81 and the direction indicator lamp 84 are arranged on the side of the pulling input side case 40. Therefore, even if the left and right light covers 83R and 83L are arranged above the left and right side covers 82R and 82L, the vertical dimension including the side cover and the light cover can be made compact.
