  The front panel 44 has a front cover 52 that forms a front surface of a handle frame 51 that is erected in a reverse U-shape in front view, the upper portion of which is also used as a gripping portion 51A at the right front end of the body frame 1, and a rear surface thereof. The rear cover 53 to be formed and the top cover 54 to form the upper surface thereof are provided, and the front surface thereof is formed in a hollow shape having a substantially arc shape in a side view, and the left side of the top cover 54 adjacent to the cutting conveyance unit 4 The display panel 43 is provided at the site, and the control lever 42 is provided at the right side of the top cover 54 away from the cutting and conveying unit 4.

  The display panel 43 is equipped with a plurality of indicators 55 (an example of a display device) for lighting and displaying an abnormality in the oil lubrication system, an abnormality in the charging system, an engine tachometer (an example of the display device) 56, and the like. .

  The control lever 42 is configured as a cross swing neutral return type, and by swinging in the left-right direction, the aircraft turns in a direction corresponding to the operation direction with a turning radius corresponding to the swing operation amount. As shown, the left and right steering clutches (not shown) and steering brakes (not shown) installed in a mission case (not shown) are operated and linked via a steering linkage mechanism 57. The lifting control valve (not shown) for controlling the operation of the lifting cylinder 22 is moved up and down so that the cutting and conveying unit 4 moves up and down toward a predetermined upper limit position or lower limit position by the swinging operation in the front-rear direction. The operation is linked through the linkage mechanism 58.

  The front panel 44 is formed so that the right side portion, which is the lower portion of the control lever 42 in the front cover 52 and the top cover 54 bulges forward, so that the right side portion away from the cutting and transporting unit 4 is located inside the portion. It has a bulging portion 44A that expands the space, and effectively utilizes the internal space of the expanded right side portion, and the steering linkage mechanism 57 and the lift linkage mechanism so as to pass through the internal space. 58 are deployed.

  In other words, by forming the front-facing bulging portion 44A in the right portion of the front surface of the front panel 44, the steering lever 42 is used for steering the cross-swing type control lever 42 at a position below the control lever 42 inside the front panel 44. The relatively large space required for operating the linkage mechanism 57 and the lifting linkage mechanism 58 can be secured, and accordingly, the steering linkage mechanism 57 and the lifting linkage for the control lever 42 can be secured. The mechanism 58 can be easily linked. In addition, by setting the formation position of the bulging portion 44A to the right side portion of the front panel 44, the operator can visually observe the tip of each divider 16 in the sitting posture while expanding the internal space of the right side portion. In this case, the possibility that the bulging portion 44A is obstructive is avoided.

  The front cover 52 is detachably connected to the handle frame 51 by a bolt 59 with a knob, and a front lamp 60 formed in an oblong shape in a front view is formed at the front end of the right side portion thereof, and the lower side thereof from the upper side. Also, a headlamp mounting portion 52A for mounting in a forward tilting posture in which the upper side is positioned closer to the front side of the machine than the lower side is recessed, and the upper side is closer to the cutting and conveying unit 4.

  As shown in FIGS. 1, 2, and 9 to 11, the headlamp 60 is formed in a vertically long oval shape and a reflector 61 having a reflective surface 61 </ b> A formed on the surface by aluminum vapor deposition, and the reflector 61. The upper and lower halogen bulbs 62 are attached to the attachment holes 61B formed in both the upper and lower portions so that they can be easily attached and detached from the rear, and the front surface of the reflector 61 and the upper and lower halogen bulbs 62 are covered from the front. The lens 63 is formed in a substantially vertical bowl shape, and a ring-shaped seal 64 interposed in close contact between the outer periphery of the reflector 61 and the inner periphery of the lens 63. The headlamp mounting portion 52A formed on the right front end of the front cover 52 is configured such that the lower side of the headlamp is closer to the cutting and conveying unit 4 than the upper side, and the upper side is In inclined posture before positioned on the body front side than part side, the optical axis a is equipped projected to be horizontal.

  In other words, the headlamp 60 is configured in a vertically long two-lamp type with two halogen bulbs 62 at the top and bottom, and is formed at the front end of the bulging portion 44A that bulges forward on the front surface of the front panel 44. It is arranged in a state of projecting further forward from its front end, and is located on the front side of the machine body relative to the front panel 44 and the pulling device 17 of the cutting and transporting unit 4. When traveling or working, for example, the front of the boarding operation unit 3 including the front panel 44 (a predetermined range from the right front side of the boarding operation unit 3 to the left front side) is naturally cut at the front left side of the aircraft. The front end portion of the transport unit 4 and its periphery can be illuminated brightly without being blocked by the front panel 44, the pulling device 17, and the like.

  Further, the headlamp 60 is disposed on the right side portion of the front panel 44 erected on the right front end portion of the body frame 1 in a right-side down posture so that the lower side approaches the cutting conveyance unit 4 on the left side of the body. Compared to the case where the two parts are arranged in a vertical posture away from the cutting and conveying unit 4, the light from the lower halogen bulb 62 is used to move the front end of the cutting and conveying unit 4 located on the front left side of the machine body and its periphery. It is possible to illuminate more brightly, and the state in which the lower side of the headlamp 60 protrudes further forward from the front end of the bulging portion 44A of the front panel 44 by bringing the lower side of the headlamp 60 closer to the cutting and conveying portion 4 as described above. Even if the headlamp 60 is installed in a tilted-down position approaching the cutting and conveying section 4 on the left side of the aircraft as the upper side thereof, the upper portion of the headlamp 60 close to the height position of the driver's eyes is generated. Front panel close to the cutting and conveying section 4 By positioned on the left side portion 44, the operator of the seating posture becomes upper side baffle of the headlight 60 when viewing the tip of each divider 16 can be avoided in advance such a disadvantage.

  In addition, since the headlamp 60 is arranged in a state of projecting further forward from the front end of the front panel 44, the light from the headlamp 60 is located above the front panel 44 in the vicinity of the headlamp 60. The control lever 42, the display panel 43, etc., which are arranged in the vehicle, can be easily operated by operating the control lever 42 or visually checking the engine tachometer 56 during nighttime traveling or work traveling. In particular, by illuminating the display panel 43 relatively lightly with the light from the headlamp 60, it is possible to effectively suppress the possibility that the driver feels dazzled when the indicator 55 is suddenly turned on at night.

  In addition, since the lens 63 is formed to bulge into a substantially vertically long bowl shape, the lens itself can be provided with high rigidity.

  As shown in FIGS. 1, 2 and 9 to 13, the reflector 61 is engaged with the upper and lower mounting holes 52 </ b> B formed in the headlamp mounting portion 52 </ b> A of the front cover 52 on the upper and lower ends of the rear surface. The engaging projection 61C is formed, and a multi-reflector portion 61D formed in a multi-sided concave shape including a plurality of reflecting elements 61a is provided above and below the front surface serving as the reflecting surface 61A. A mounting hole 61B for mounting a valve is formed at the rear end portion (recessed bottom portion) of each multi-reflector portion 61D.

  The upper and lower multi-reflector portions 61D have the same shape, and in the mounting posture, the upper multi-reflector portion 61D is positioned on the front side of the machine body relative to the lower multi-reflector portion 61D, and a plurality of reflecting elements 61a provided for them. The lower left side portion and the upper end portion serve as a reflection area A1 for front light distribution in which light from the halogen bulb 62 is diffusely reflected toward a predetermined range in front of the aircraft along the optical axis a in the vertical direction. The lower right portion of the light distribution diffuses and reflects the light from the halogen bulb 62 toward the cutting and conveying unit 4 located in a predetermined range on the left front side of the airframe on the left side of the optical axis a. In addition, a reflection area for light distribution below that diffuses and reflects light from the halogen bulb 62 toward a predetermined range below the front of the aircraft, which is below the optical axis a, on the upper portion thereof. It is formed to have a A3.

  That is, the upper and lower multi-reflector portions 61D are for reflected light from the front light distribution area A1 while irradiating a predetermined range in front of the fuselage from the boarding operation unit 3 side while focusing on the far side. The reflected light from the reflective area A2 irradiates the predetermined range on the left front side of the machine body where the cutting and conveying unit 4 is disposed, and the reflected light from the reflecting area A3 for light distribution below and the reflected light from the cutting and conveying part 4 It is configured to irradiate a predetermined range in front of the aircraft where each divider 16 and the road surface just before are located, so that the irradiation range is set to the left of the aircraft while securing the irradiation amount in front of the aircraft. And wide-angle illumination extended forward and downward can be performed well.

  Further, due to the light distribution described above, the left light distribution toward the cutting and conveying unit 4 on the left front side of the machine body with respect to the light from the halogen bulb 62 heading forward of the machine body and the reflected light from the reflection area A1 for front light distribution. Cross-lighting in the left-right direction (see FIG. 12) that intersects the reflected light from the reflective area A2 for the vertical and the cross in the vertical direction that intersects the reflected light from the reflective area A2 for the left light distribution toward the front and lower of the aircraft Lighting (see FIG. 11) can be performed in front of the boarding operation unit 3, so that the halogen bulb 62 adopts a low output that can suppress power consumption, while the front of the boarding operation unit 3 can be used. It is possible to illuminate brightly with an appropriate amount of light in a concentrated manner, thereby making it feel brighter than when the front of the aircraft is illuminated uniformly as a whole.

  Moreover, since the posture of the headlamp 60 is set to the right-tilt posture in which the lower side is closer to the cutting and conveying unit 4 than the upper side, the lower halogen bulb 62 and the multi-reflector portion 61D are placed on the upper halogen bulb 62 and While approaching the cutting and conveying unit 4 more than the multi-reflector unit 61D, the upper and lower halogen bulbs 62 and the upper and lower cross-lighting portions by the multi-reflector unit 61D are cut and conveyed by the lower cross-writing portion than the upper cross-writing portion. As a result, the front end portion and the periphery of the cutting and conveying unit 4 can be more effectively illuminated, and the upper and lower cross-lighting portions overlap in the left-right direction. Excessive lighting can be avoided.

  As a result, when traveling at night or during work, the front multi-reflector unit 61D of the headlamp 60 illuminates the front of the boarding operation unit 3 in a brighter and wider area, thereby improving the forward visibility. While ensuring, it is possible to more effectively illuminate the front end of the cutting and transporting unit 4 located in the lower front side of the machine body and its surroundings, and the divider 16 provided at the front end of the cutting and transporting unit 4 Visibility to planted cereals and the like located in the vicinity thereof can be improved.

  As shown in FIGS. 11 to 13, the plurality of reflective elements 61 a provided in the multi-reflector part 61 </ b> D can obtain a predetermined light distribution pattern by diffuse reflection to a predetermined irradiation range by the respective reflective areas A <b> 1 to A <b> 3. Each is formed so as to have a unique optimum three-dimensional curved surface, and many of them are formed in a vertically long shape that facilitates subdivision of light distribution in the left-right direction. On the other hand, each halogen bulb 62 is attached to the corresponding attachment hole 61B in a state in which the filament 62A is vertically oriented along the longitudinal direction of the reflective element 61a.

  That is, by providing a large number of vertically long reflective elements 61a and making it easier to subdivide the light distribution in the left-right direction, it becomes easy to perform appropriate light distribution adjustment in the left-right direction by the multi-reflector unit 61D. In addition, by attaching the halogen bulb 62 so that the filament 62A is vertically oriented along the longitudinal direction of the reflecting element 61a, the light emitted from the filament 62A is efficiently diffused and reflected in the left-right direction by the multiple reflecting elements 61a.
