In addition, as shown in FIG. 6, by attaching the name of the remote control weed lever 38 to the top surface of the sub handle 36, the remote control weed lever 38 is not erroneously operated.

  Next, a side view of the gear box 15 in FIG. 9 and a cross-sectional view taken along line AA in FIG. 9 are shown for a part of the structure of the power transmission system in the gear box (transmission case) 15 of the combine of this embodiment. .

  The first shaft 51 to which power from the engine E side is transmitted has a portion in which the inner peripheral side of the first shaft side slide gear 52 having a shifter groove 52a and a gear 52b on the outer peripheral portion is spline engaged. A sleeve 53 is arranged between a portion where the inner peripheral side of the first shaft side slide gear 52 is not splined and an outer peripheral portion of the first shaft 51. The sleeve 53 has a function of rotatably bearing the first shaft side slide gear 52 on the first shaft 51.

  Further, a second shaft 57 to which a pulley 55 for power transmission to the reaping device 50 is fixed is disposed at a position parallel to the first shaft 51. A second shaft side sub-shift gear 58 is attached to the second shaft 57 in a loose fit. The second shaft side auxiliary transmission shift gear 58 is a gear having three different diameters, that is, a gear integrally including a large gear 58a, a middle gear 58b, and a small gear 58c. The large gear 58 a is always engaged with the first shaft side slide gear 52. A traveling transmission shaft 60 is provided at a position parallel to the second shaft 57, and any one of the gears 58a to 58c having the three different diameters of the second shaft side auxiliary transmission shift gear 58 is provided. The small gear 61a, the medium gear 61b, and the large gear 61c having three different diameters to be engaged are fixed to the transmission shaft 60 of the traveling system.

  Accordingly, when power from the engine E side is transmitted to the second shaft 57, any one of the gears 58a to 58c having three different diameters of the second shaft side sub-shift gear 58 is transmitted to the traveling system. The power on the engine side is transmitted to the traveling wheels (not shown) by engaging with any of the gears 61a to 61c having three different diameters of the shaft 60.

    Further, since the gear 64 that is always engaged with the large gear 63 fixedly provided on the tip side of the second shaft 57 is fixed to the tip side of the first shaft 51, the engine is attached to the first shaft 51. When power is transmitted from the side, power is transmitted to the cutting pulley 55 fixed to the second shaft 57.

  When the first shaft side slide gear 52 that is spline-engaged with the first shaft 51 is moved in the direction of arrow B by a shifter (not shown) inserted into the shifter groove 52a, the outer periphery of the first shaft 51 is moved. When the spline on the inner peripheral side of the first shaft side slide gear 52 reaches the portion where there is no spline (a portion), the first shaft side slide gear 52 loses power transmission on the engine side, and the traveling system stops driving. . On the other hand, even if the first shaft side slide gear 52 is moved in the direction of arrow B by the shifter inserted in the shifter groove 52a, the large gear 64 on the tip side of the first shaft 51 is fixed to the tip side of the second shaft 57. Therefore, the engine-side power is transmitted to the reaping device 50 because the large gear 63 is always engaged.

  With the above gear configuration, the gear box 15 can be configured in a compact manner, and by arranging shift arms (not shown) opposite to the front and rear of the gear box 15, the link configuration space is not congested and can be configured in a wide space. And maintenance are improved, and the gear box 15 can be manufactured at low cost.
