A baler includes a frame, a pickup mechanism, and a pre-compression chamber coupled to the frame rearward of the pickup mechanism. A material flow is defined at least between the pickup mechanism and pre-compression chamber. The baler includes a feeder system coupled to the frame along the material flow path and between the pickup mechanism and the pre-compression chamber. The feeder system includes a feeding mechanism for transferring crop received from the pickup mechanism to the pre-compression chamber. The feeding system includes a floor assembly and knife system. The floor assembly is pivotably coupled to the frame about a pivot to move between a raised position and a lowered position. The pivot is located rearward of the pickup mechanism and feeding mechanism such that the floor assembly and knife system pivot from the raised position to the lowered position in a direction downwardly and towards a rear of the baler.
