Abstract: A compactor machine can include a machine frame; at least one cylindrical roller drum rotatably coupled to the machine frame and rotatable about a drum axis oriented generally transverse to a direction of travel of the compactor machine; a plurality of cameras mounted to the machine frame so as to provide a 360° bird's eye view of an area around the machine; a display showing the 360° bird's eye view; and a controller; wherein, the controller is configured to determine certain conditions regarding a compacting operation of the compactor machine and the controller overlays a highlight symbol on the 360° bird's eye view on the display notifying a machine operator of the certain conditions.

Abstract: A vibratory compactor includes a roller and an eccentric shaft. The roller is rotatably mounted on a main frame and may include a first vertical support and a second vertical support. The eccentric shaft is rotatably connected between the first vertical support and the second vertical support in the roller. The eccentric shaft includes a first end, a second end, a first eccentric weight, a second eccentric weight, and a center portion, casted as a single piece. The first eccentric weight is proximal to the first end and the second eccentric weight is proximal to the second end. The center portion may be disposed between the first eccentric weight and the second eccentric weight. The center portion may include at least one cavity on a surface of the center portion. The at least one cavity is elongated between the first eccentric weight and the second eccentric weight.
