Abstract: An agricultural amphibious bait feeding boat includes a boat body. A bait feeding device is fixed to one end of the boat body, and a propulsion device is fixed to the other end of the boat body. The boat body includes two foam floating bodies, foam fixing carbon rods, a transverse carbon rod, tube ferrule fixing assemblies, and tee joints. The two foam floating bodies include a left foam floating body and a right foam floating body, the foam fixing carbon rods parallel to each other are respectively arranged above the two foam floating bodies, and the foam floating bodies and the foam fixing carbon rods are fixed through the tube ferrule fixing assemblies. The transverse carbon rod is connected to the foam fixing carbon rods through the tee joints, and the left foam floating body and the right foam floating body are fixedly connected to each other.

Abstract: A drawbar assembly for a motor grader is provided. The drawbar assembly includes a yoke plate, a backbar, a drawbar tube, and a sleeve. The yoke plate includes a first surface and a second surface. The backbar is attached to the first surface of the yoke plate. The backbar includes a tube facing surface. The drawbar tube includes a first end and a second end. The drawbar tube is attached to the first surface of the yoke plate, defining a clearance between the first end of the drawbar tube and the tube facing surface of the backbar. The sleeve encloses at least a portion of the drawbar tube. The sleeve includes a backbar attachment portion and a yoke attachment portion. The backbar attachment portion is attached to the tube facing surface of the backbar and the yoke attachment portion is attached to the first surface of the yoke plate.
