Towing wood

Towing wood

One of the first tasks I wanted Yarbo to do is transport firewood from a pile in my lawn up a hill to the back of my yard (150-200ft) around 3 cords. Does a module, i.e. the S-1/M-1/b-1 need to be attached while doing this or can the body be driven by itself? I don’t get much snow where I am, so looking to utilize Yarbo in other ways through the winter. I didn’t want to use the s-1 auger on the grass if I didn’t have to.
