Abstract
Disclosed is a mine roller for attachment to a military vehicle such as a tank. The mine roller includes a frame vertically swingably connected to the tank and a set of disks mounted to the frame for eccentric rotation thereon. A ground engagement annulus is rotatable on the outer diametrical surface of each disk to provide rolling contact between the mine roller and the ground. The frame of the mine roller extends no further from the tank than do the annuluses, thereby minimizing interference between the frame and the ground. The mine roller also has means to limit the swinging of the mine roller relative to the tank, the limiting means including a cantilever arm or spring fixed to the mine roller frame and engagable with the tank after the mine roller swings a predetermined amount.
