SB Series Small Square Balers

Bale Better Than the Rest With Newly Improved Equipment

High-quality baling isn’t just about productivity — it’s also about quality. A proper baler should help you achieve more in a day while offering accurate, stable and consistent baling at high speeds. With new smart features designed to improve bale length consistency and track data, such as bale count, bale length and more, the original lineup of SB series small square balers has been improved to help you bale better than ever before. With three industry-leading models to choose from, you’ll get the job done right knowing you’re relying on extra-wide pickups, smooth rotary feeding systems and other best-in-class advancements.
  • Plenty of Sturdy, Closely Spaced, Curved Finger Tines

    • Gently lift the crop while keeping leaves intact
    • Rugged tine bars run on sealed ball bearings for long life and trouble-free operation
  • Standard Pickup Gauge Wheels Adjust to Five Positions

    • Guides the pickup through the contours of the field
    • Allows you to get every bit of the windrow
  • Raise Pickup for Transport

    • Select the manual latch or optional hydraulic pickup lift

Feeding System

Provides For A Uniform, Well-Shaped Bale

Huge 283-sq in (1,826-sq cm) feed opening allows SB balers to swallow large, uneven windrows. From here, a uniform, well-shaped bale is produced by the dependable Case IH feeding system:

  • High-throughput rotary feeding system delivers high capacity in any crop
  • Heavy-duty, double-rotating tines overlap to feed crop smoothly and continuously
  • Adjustable double-packer fork folds hay into the bale chamber
  • No-plug feeding system effortlessly moves crop from the pickup area to the bale chamber with minimum shatter loss

Density Control

Easy Bale Density Control

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.

  • Provides "set-it-and-forget-it" convenience
  • Ensures consistent bale weight and density

Ties & Twists

Handle Challenging Baling Conditions

Case IH small bales hold up to handling from the rack to the elevator and from the barn to the bunk.
  • Dependable Gear-driven Twine Knotters:

    • Hard-surface material at all wear points
    • Bill hooks are chrome plated for extra durability and reduced maintenance
    • SB541 is also available with a gear-driven wire twister
  • Large-Capacity Twine Storage Increases Field Time Between Refills:

    • SB531— load six balls of twine
    • SB541 and SB541C— load eight balls of twine
    • SB541 wire-tie version features four-coil wire storage
