Wide implement haulage boom - has pivot coupling to bring road wheels into position for endwise transport by road

摘要

The haulager boom is for disc harrows and other wide agricultural implements, to allow transport along public roads. It pivots through 45 deg. so as to bring the road wheel into the working position and allow the harrow etc. to be hauled endwise along the road. The wheels can be moved hydraulically or mechanically between the working and stowed positions.
