That is, the direction indicated by reference numeral F in fig. 1 and 2 is the front side of the machine body, and the direction indicated by reference numeral B in fig. 1 and 2 is the rear side of the machine body. The direction indicated by reference symbol L of fig. 2 is the left side of the body, and the direction indicated by reference symbol R of fig. 2 is the right side of the body.
Fig. 1 shows the front of a conventional combine harvester. The travel machine body of the combine harvester is provided with a machine body frame 1 and a crawler travel device 2. A harvesting part 3 for harvesting crops (vertical grain stalks) in a farmland is arranged in front of the traveling machine body. The harvesting section 3 has: a reel 4 for pulling in the vertical grain stalk; harvesting the cutter 5, and cutting the vertical rice straw; and an auger 6 for transversely conveying and collecting the harvested rice straw in the harvesting width direction and feeding the harvested rice straw backward. A steering unit 7 is provided behind the harvesting unit 3. The cab 8 covers the cab 7. A grain storage box 9 for storing grains after threshing is provided behind the driving part 7. The threshing device 10 for threshing the whole straw from which the straw is harvested is disposed in a state of being arranged in the transverse direction to the grain storage box 9. The harvester 3 and the thresher 10 are provided with a conveyor 11, and the conveyor 11 conveys the whole straw from which the grain straw is harvested toward the thresher 10.
As shown in fig. 1 and 2, the driver section 7 includes a driver seat 12, a front panel 13 having various operation elements, and side panels 14. Although not shown, a power unit is provided below the driver unit 7. The power unit includes an engine, a radiator, and the like. The upper part of the power unit is covered with an engine cover 15. The driver seat 12 is supported by an engine hood 15.
The cab 8 has an upper roof panel 16, a front glass cover 17 at the front, and a left glass window 18, and the cab 8 covers the cab 7. A passenger compartment 19 is formed in the right side portion of the cab 8, and the passenger compartment 19 is closed by an openable and closable door 20. A dust box 21 for sucking combustion air of the engine is provided on the rear side of the door 20.
The rear pillar 22 located at the rear of the door 20 has a hinge 23 supporting the rear of the door 20. The door 20 is supported by a rear pillar 22 so as to be swingable about an upper and lower axial center via a hinge 23.
The front pillar 24 is provided with a grip 25. The grip portion 25 is located on the side of the front pillar 24 and extends vertically along the front pillar 24.
The grip portion 25 extends from a position of the front pillar 24 corresponding to an upper portion of the door 20 to a position corresponding to a lower portion of the door 20.
