DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The management machine shown in FIG. 1 has an engine 1 mounted on a front upper part of a fuselage 6 having a transmission case 7 on the rear side, and an axle on both lower sides of the transmission case 7, which is a lower part of the fuselage 6. 2 is mounted on the axle 2, and an axle-mounted working device A including a mounting tool 3 detachable from the axle 2 and a plurality of tilling claws 4 mounted on the mounting tool 3 is mounted on the axle 2, On the upper side of the transmission case 7,
A steering handle 81 extending rearward and upward through the handle frame 8 is attached. Further, rotational power transmitted from the engine 1 to the transmission case 7 is transmitted to the attachment 3 via the axle 2. The attachment 3 is fixed to the connecting cylinder shaft 41 that is detachably connected to the axle 2.
An outer mounting member 40 having a rectangular claw mounting plate 42 to which a plurality of tilling claws 4 can be mounted;
0 between the transmission case 7 and the transmission case 7,
An axle 2 and an inner attachment (not shown) having a plurality of tilling claws 4 detachably attached to the outer attachment 40. In the above-described management machine, a resistance bar 10 is integrally formed at one end in the length direction on the rear side of the transmission case 7 provided on the body 1, and a tail wheel 11 is freely rotatable at the other end. Rotating frame 15 supported by
Are mounted so that the positions thereof can be changed between a resistance rod action position where the resistance rod 10 contacts the ground and a tail wheel action position where the tail wheel 11 contacts the ground, about the rotation shaft 14 extending in the longitudinal direction of the vehicle. In the embodiment shown in FIG. 1, a hitch 12 is attached to the rear side of the transmission case 7, and a support 13 having a support cylinder 13 a at the lower end is supported on the hitch 12 so that the height of the support 13 can be adjusted with respect to the hitch 12. And the rotating frame 1
The rotation shaft 14 protrudes from a middle portion in the longitudinal direction of the support member 5, and the rotation shaft 14 is rotatably inserted into and supported by a support cylinder 13 a of the support 13, and the rotation supported by the support cylinder 13 a is supported. By rotating the rotary frame 15 about the shaft 14, one of the resistance bar 10 and the tail wheel 11 is advanced to the lower operation position, and at this time, the other side is at the operation position. On the other hand, it is configured to be retracted to the upper non-operating position, and a lock pin 16 is provided between the support cylinder 13a and the rotating shaft 14 so as to be able to be inserted and removed, and the resistance bar 10 and the tail wheel 11 are moved downward. When rotated to the side working position or the upper side non-working position, the resistance bar 10 and the tail wheel 11 are configured to be locked at the respective positions via the lock pins 16. To the point where the wheel 11 touches the ground Is the H1, is from the center of the rotating shaft 14 of the resistance bar 10 is longer than the length H2 of up to the ground point for grounding. Next, the operation of the management device configured as described above will be described. First, when the axle 2 is mounted on the axle 2 of the transmission case 7 and cultivation of a field is performed by the axle-mounted working device A, the rotation shaft 14 supported by the support cylinder 13a is removed with the lock pin 16 removed. The rotation frame 15 is rotated so that the tail wheel 11 is retracted to a non-operation position above the tail wheel operation position, and the resistance bar 10 advances to the resistance bar operation position,
After that, the lock pin 16 is inserted between the support cylinder 13a and the rotating shaft 14 to lock, and the locking moves the resistance bar 10 and the tail wheel 11 to the working position and the non-working position, respectively. Hold in the locked state. By running the body in such a state, the running speed of the body is adjusted by the ground resistance by the resistance bar 10, and the tilling depth by the axle-mounted working device A can be adjusted. When the vertical position of the resistance bar 10 is adjusted according to the soil condition and the working depth, the vertical position of the resistance bar 10 can be easily changed by adjusting the vertical position of the support body 13 with respect to the body. When the resistance bar 10 is lowered with respect to the fuselage by adjusting the position of the resistance bar 10, the operator does not push down the steering handle 81 in other words, in other words, the fuselage 6 is viewed from a further side view. Therefore, the resistance rod 10 can be buried deeper in the ground without lowering the front height and the height, and the load of the engine 1 can be sufficiently applied to the axle-mounted working device A. Therefore, a sufficient traction force can be obtained, and the aircraft 6 can be effectively traveled to perform a good tilling operation. When the management machine is moved to a field or moved to another field after the work is completed, the rotating frame 15 is moved to the rotating shaft 1 with the lock pin 16 removed.
4, the resistance bar 10 is retracted to the non-operation position above the resistance rod operation position, and the tail wheel 11 is advanced to the tail wheel operation position. The tail wheel 11 is positioned and locked through the lock pin 16 in such a state, so that the aircraft can be moved using the tail wheel 11. When performing the tilling work of the same tilling depth as the previous field in the next field, since the vertical position of the resistance rod 10 is set in the previous field, the simple operation of reversing the rotating frame 15 again immediately immediately The tilling work can be started by positioning the resistance bar 10 at an appropriate biting position, and the working efficiency can be improved as a whole. In addition, by adjusting the vertical position of the support 13, the range of action of the tail wheel 11 can be increased, so that the posture can be easily changed to a comfortable posture for the worker according to road conditions such as when moving on a slope. You can do it. As described above, when properly using the resistance bar 10 or the tail wheel 11 according to the working state of the management machine, the lock bar can be used without removing and replacing the resistance bar 10 or the tail wheel 11 as in the related art. A pin 16 is inserted and removed, and the rotating frame 15 is connected to its rotating shaft 14.
With the simple operation of rotating around the center, the resistance rod 1
0 and one side of the tail wheel 11 can be quickly advanced to the operation position, and therefore the work efficiency can be improved.
In addition, since the unused ones of the resistance bar 10 and the tail wheel 11 are retracted to the non-operation position via the rotating frame 15, the troublesome work of separately storing unused ones can be eliminated. In addition, it may not be necessary to secure a storage place. In addition, the length H from the center of the rotating shaft 14 to the contact point where the tail wheel 11 contacts the ground is
1 is longer than the length H2 from the center of the rotating shaft 14 to the contact point where the resistance rod 10 contacts the ground, so that the axle is mounted while the body 6 is almost horizontal as shown in FIG. If the vertical position is adjusted so that the tip of the resistance bar 10 is located below the lowermost end of the work device A, when the tail wheel 11 is used by inverting the use state of the resistance bar 10 as it is, Since the tail wheel 11 is always grounded below the grounding length of the resistance rod 10, the tilling claw 4 can always be reliably lifted from the ground, and the management machine can be moved to the field or moved to another field after the work is completed. In such a case, the operator can move the body in a comfortable posture without forcibly lifting the front part of the body.

[Effects of the Invention] As described above, according to the present invention,
