Abstract
A rotary vegetation cutting unit having: a frame having a drive shaft; at least one cutting element that moves with the frame; and a debris blocking assembly on the frame with a unitary part that moves relative to the frame in opposite directions around an operating axis. The unitary part is configured to deflect away from the at least one cutting element objects approaching the at least one cutting element in a radial direction. The rotary vegetation cutting unit further has a bearing assembly including: a) a bearing that guides movement between the unitary part and the shaft; and b) a holder for the bearing. The rotary vegetation cutting unit is configured so that any debris spaced radially from the rotary vegetation cutting unit is required to traverse a non-straight path to contact the bearing.
