When working with this vibrating type work machine, for example, when performing plowing work with a vibrating type deep tiller, a tilling rotor is installed at the rear of the vibrating type deep tiller. You may want to be able to do the work on the frame that will be done later to create the cultivation bed.

However, if you try to do this, if the work equipment installed behind the vibrating work machine requires driving, such as a tilling rotor, the transmission mechanism for driving it will not work properly.
