Abstract
Tines of a baler pre-cutter rotor each include a plate having a plurality of points disposed at equally spaced locations about a rotation axis of the rotor, with each point having a leading region reinforced by a pair of straps fixed in sandwiching relationship to the point. In one embodiment, the pair of straps is also applied to opposite sides of a trailing region bordering a circular mounting hole of the plate. In another embodiment, a second pair of straps abuts each first pair of straps and reinforces a leading region bordering the circular mounting hole. Instead of the second pair of straps, a ramp may be provided on a side surface of the plate for deflecting crop towards a pre-cutter stationary cutting knife. Instead of including separate straps, the tines can be cast or forged as identical sections including a tine point.
