Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention is an improvement of the carrying tool, more specifically, it is possible to stably carry the carrier while maintaining a good supporting posture, and it is possible to omit the positioning adjustment at the supporting portion of the claw blade portion, and The present invention relates to a rotary tractor for agricultural tractors that can reliably protect a claw blade.
[0002]
[Prior art]
As is well known, a rotary is attached to the rear of a tractor and the tow is performed while rotating a claw blade of the rotary in order to plow a field or the like. By the way, when detaching this rotary, this rotary is very heavy and the claw blades are exposed downward, so that it cannot be placed on a normal bogie while maintaining a good posture. Falling out of balance was extremely dangerous.
[0003]
Therefore, conventionally, as a device for transporting such a rotary, a device has been disclosed in which a support is integrally attached to a cover of the rotary and can be transported in a suspended state using the support (see Patent Document 1). . However, in the case of this support, since it is supported only by the mounting bracket, the load may be concentrated on the mounting portion and may be damaged, and furthermore, there is a risk that the rotary falls and the worker is injured, The rotary itself may be damaged.
[0004]
In addition, there is disclosed one in which a part is attached to a rotary cover and a rotary claw shaft is supported (see Patent Document 2). However, in the case of this support, in order to support the claw shaft, the positioning must be adjusted so that the claw shaft support base does not interfere with the tilling claw, work is troublesome, and the tilling claw is damaged by mistake in the support position There is a risk of doing it.
