FEEDING SYSTEM

 Huge 283-sq.-in. (1,826-sq.-cm) feed opening allows SB balers to swallow large, uneven windrows. From here, the dependable Case IH feeding system takes over, providing a smooth flow of crop into the bale chamber for a uniform, well-shaped bale.

DENSITY CONTROL

Hydraulic density control is standard on the SB551 and optional on SB531, SB541 and SB541c.

All SB Series balers allow for easy bale density control by adjusting the tension applied to the bale chamber. For manual density control, tension springs are an economical choice.
