Abstract: A drum assembly for a vibratory compactor and method of retrofitting a vibratory compactor to measure the acceleration and/or vibratory movement of a drum rotatably mounted on the frame of the vibratory compactor. The drum assembly may comprise a drum including a shell, a mounting wall disposed inside the drum and a bulkhead disposed inside the drum and attached to the shell, a first bearing disposed between the frame and the mounting wall, a second bearing, a sensor, and a strap. The first bearing may include an inner race fixedly mounted to the frame. The second bearing may comprise a hub and a bearing shaft circumscribed by the hub and mounted to the bulkhead of the drum. The strap may be attached to the inner race and the hub.

Abstract: A hitch system between a first portion and a second portion of a machine includes a first frame with the first portion and a second frame with the second portion. A first axis is disposed along the machine's length and second axis along the machine's height. A link rotatably connects to the first frame at a first ball joint portion and the second frame at a second ball joint portion. A handlebar with the first frame includes a third ball joint portion, which is co-axial with the first axis and the second axis, and to which a coupler link is rotatably connected. The coupler link includes an oscillation restrictor pin. A relative play between an intermediary link with the first frame and the oscillation restrictor pin facilitates a restricted oscillation between the first portion and the second portion of the machine.
