ある。2. Description of the Related Art Conventionally, in this type of walk-type cultivator, usually, in order to perform work while setting the plowing depth so as to have a constant plowing depth, a sled body that follows the ground surface is used as a plowing device. It is well known that the mounting height can be freely set, and the mounting height can be integrated with the tilling device so as to be vertically movable. In addition to the sled body, conventionally, a resistance body that can give resistance to the aircraft's running is immersed in the ground so that the force to move forward against the aircraft due to the plowing reaction force when the field is hard does not act strongly. It is also well known that the structure is attached to the tiller in a ready state.

ことができる歩行型耕耘機の提供を目的とする。However, in the past, since the sled body and the resistance body were separately constructed and attached to the tiller, when the sled body was used and when the resistance body was used. Therefore, it has been troublesome to change the use postures individually. The present invention has been made in view of the above circumstances, and when the sled body is used and when the resistor body is used, switching between the sled body and the resistor body to the use posture is performed by a simple operation. The purpose is to provide a walk-behind cultivator that can be used.

る。In order to achieve the above-mentioned object, a walk-type cultivator according to the present invention has a cultivating depth configured to level the ground surface with a cultivating device mounted on the rear portion of a traveling body. A grounding tool provided with a sled body for setting and a resistance body that immerses in the ground to give a running resistance to the traveling machine body is provided, and the lower end of the sled body is compared with the lower end of the resistance body. And a state in which the lower end of the resistor is relatively lower than the lower end of the sled body is switchable. The operation and effect of this characteristic configuration are as follows.

きる。That is, a sled body and a resistor are provided on one grounding tool, and in the grounding tool, a state in which the lower end of the sled is located relatively lower than the lower end of the resistor, Since the lower end of the sled body is arranged to be relatively lower than the lower end of the sled body, the resistance body is mainly used by a simple operation such as switching the posture of the grounding tool. The sled body can be switched to a state where it is mainly used.

るに至った。Therefore, it is possible to switch between the state in which the resistor is mainly used and the state in which the sled is mainly used by a simple operation, so that it is not necessary to perform the work for individually changing the use posture. Since the workability can be improved and the workability can be improved, the number of parts can be reduced by providing both the sled body and the resistor body on the grounding tool.

面中に没入させるようにする。With the above structure, the pin 12 is mounted in the rear through hole 14 and the pin 12 is engaged with the appropriate concave portion 19 of the rod-shaped member 15, so that as shown in FIG.
The lower end portion of the sled body 17 can be in a sled body use posture in which the lower end portion is located below the resistance rod 18, and the pin 12 is removed from the rear hole through hole 14 and attached to the front hole through hole 13. By engaging an appropriate concave portion 19 of the rod-shaped member 15 with the pin 12, the lower end portion of the resistance rod 18 can be positioned below the sled body 17 as shown in FIG. It should be noted that the rod-shaped member 15 is provided to the recess 19 engaged with the pin 12 and the rear edge portion of the bracket 11 at the rear end portion of the rod-shaped member 15 regardless of whether the sled body is used or the resistor is used. The posture will be maintained by the contact with. Therefore, it is possible to change the height position of the grounding tool 10 with respect to the ground by manually gripping the gripping portion 16 and engaging and disengaging the pin 12 of the recessed portion 19 and the vertical position changing operation. When the working depth is set to a predetermined level, the sled body 1 is set with the grounding tool 10 in the sled body use posture.
In order to smooth the ground surface at 7 and prevent the traveling body A from unreasonably advancing due to the plowing reaction force when the field is hard, the grounding tool 10 is set to the above-described posture of using the resistor and the resistance rod 18 is set in the ground. Try to immerse yourself in.
