It is formed in a loop shape from a grip portion forming body 33 integrally formed in a frame shape.
A clutch lever 33a is held together with the holding portion forming body 33 of the handle 30 so that the operation can be performed while maintaining the power connection state of the clutch mechanism according to the operation position of the operation lever 4 shown in FIG. Can be done.
When the clutch lever 33a is released, the clutch lever 33a is restored to the upright state by the rotation biasing force, and the clutch mechanism is held in the power disconnected state.

Further, as shown in FIGS. 3A and 3B, at the front center of the handle main body 32, an operation lever 4 that can be tilted to the left and right for performing a switching operation between the traveling speed change and the rotary speed change is inclined backward. A lever guide having a lever guide groove 5a having a width that can be freely moved in the lateral direction corresponding to the positions of "reversing", "neutral", "moving", "plowing", and "plowing on the spot" A panel 5 is attached to the handle base bodies 31 and 31.
And the display (H) of “reverse, neutral, movement, plow, plow on the spot” is displayed in order from the left side, and each power transmission operation is performed by setting the operation lever 4 to each display position in the left-right direction. Can be done.
Further, the operation position identifying means S of the operation lever 4 of the present invention is inclined forward from the middle part of the operation lever 4 and close to the upper part of the display part of the lever guide panel 5 as shown in FIGS. 3 (a) and 3 (b). It is attached so that it may become substantially parallel. In the present embodiment, a magnifying lens is adopted as the operation position identification means S.
With the above configuration, by moving the operation lever 4 in the left-right direction, the “plow” position can be clearly identified at a glance as shown in FIG. I can do it.
Further, the lever guide panel 5 is provided with a protrusion 5b so that the operation lever 4 does not go unconsciously at the “reverse” position at the left end and “plow on the spot” at the right end.

The rotary tiller 2 is covered with a rotary cover 21 from the top of the rotation trajectory of the tillage claw 18 to the front.
The rotary cover 21 is fixedly attached to the middle portion of the transmission case 14 and is supported by an attachment rod 21a that is extended with the rear side also serving as the handle portion 22.
That is, the mounting rod 21a can be formed into a U-shape in a plan view and protrude rearward from the rotary cover 21 to be a grip portion 22 that can be gripped when the machine body is lifted.

  Further, the mounting rod 21a is supported by a rigid structure by connecting the rear side thereof to the front end portion of the transmission case 14 by a connecting frame X. The connecting frame X rotates the lifting / lowering wheel support arm 23a that pivotally supports the lifting / lowering wheel 23. Dynamic adjustment is possible (height adjustment is possible).

  As a result, when the elevating wheel 23 is set at the lowest position shown by the solid line in FIG. 1, the rotary tiller 2 can be levitated and supported in a direction away from the ground between the traveling wheels 16 and 16, and the road travels smoothly. It can be performed. Further, if the lifting and lowering wheels 23 are sequentially positioned and fixed upward as shown by the dotted lines in the figure, the rotary tiller 2 can be lowered stepwise based on the ground contact position of the traveling wheels 16 and 16, and the tilling depth is gradually increased. Tillage work can be performed.

The rotational power of the engine 11 switched by the switching operation is transmitted from the transmission case 14 to the tilling shaft 17 to drive the tilling claw 18 in the normal direction.

  In the above configuration, when the operator starts the engine and travels the machine body 1 to perform farming work, when traveling on the road, the rotary tiller 2 is arranged as shown by the solid line in FIG. If the control lever 4 is set to the highest position, the position of the operating lever 4 is adjusted to the moving position of the lever guide panel 5, and the clutch lever 33a attached to the tip of the handle 32 is gripped to the solid line position in FIG. When the power transmission is driven and the fuselage 1 moves forward, on the contrary, when the user wants to move backward, set the position of the operation lever 4 to the reverse position of the lever guide panel 5 and hold the clutch lever 33a in the same manner as described above. For example, the airframe 1 moves backward.

  In the case where the tilling operation is performed while the machine body 1 is traveling, the mounting position of the elevating wheel 23 is set as shown by the chain line position in FIG. If the position of the lever guide panel 5 is set to the plowing position and the clutch lever 33a is gripped in the same manner as described above, the power transmission device drives the axles 15 and 15 and the tilling shaft 17 so that the machine body 1 While plowing work, the vehicle runs forward.

  Further, when plowing work is performed on a hard field, the lever guide of the operation lever 4 is set with the mounting position of the elevating wheel 23 set as shown by the chain line position in FIG. 1 according to the desired plowing depth. If the position of the panel 5 is set to the plowing position and the handle 32 is lifted gradually while grasping the clutch lever 33a on the handle 32, the power transmission device drives only the tilling shaft 17 and the airframe 1 In a state where the traveling of the vehicle is stopped, it can be plowed to a predetermined depth like a normal field.

  The present invention provides an operation device for a mobile vehicle having an operation lever 4 that can be moved and operated along a guide groove 5 a of a lever guide panel 5, and includes display portions H corresponding to the operation positions of the operation lever 4. Since the operation position identifying means S that moves above the operation position display portion H in conjunction with the operation 4 is provided, the operation lever 4 is set to various operation positions of the lever guide 5 in conjunction with the operation of the operation lever 4. At the set stage, the operation position (reverse) (neutral) (neutral) (moving) (plowing) (by plowing) (with the magnifying glass of one embodiment of the operation position identifying means S attached to the middle of the operation lever 4 inclining forward) It is possible to improve the visibility by clearly enlarging (plowing on the spot) and improve the visibility, and it is possible to provide an operation device that is easy to use for people unfamiliar with the machine with peace of mind.
