Achieve High-Efficiency Hay

TwinePro
Accumulators
Feedrate Control

New for Model Year 2020

The new design allows for up to 30% increased knot strength. Bale density may be increased using the same twine or current bale density maintained using lower strength twine.

Improved Forage Quality

The knot looping process eliminates offcuts, which prevents twine pieces contaminating feed and reduces environmental impact.

Automatic and Uniform

Fully automatic

Reduces loading time by up to 50%

Holds three to five bales

Dumps uniform, pickup-ready bales

Works on a variety of bale lengths and conditions

Available in vertical and horizontal stacking models

AC3108: standard horizontal three-bale accumulator for 3x3 bales
AC4108: standard horizontal three-bale accumulator for 4x3 bales
AC5150: horizontal five-bale accumulator for 4x3 bales
VS1206: vertical three-bale accumulator for 4x3 bales

Advanced Baling Technology

Feedrate Control enables the baler to run at optimal performance by controlling the speed of the tractor. Using Feedrate Control, the baler controls the tractor’s forward speed through ISOBUS Class 3 commands, maintaining desired capacity by using a charge sensor. The system then calculates the best speed based on the information received from the sensors.

Charge Control

Charge Control automatically adjusts the tractor's speed to reach optimal capacity inside the baler. This results in a higher feedrate throughput by up to 9 percent overall. Available on LB334R, LB434R and LB434R XL rotor cutter configurations.

Slice Control

Slice Control automatically adjusts the tractor's speed based on bale slice thickness. This allows the operator to predetermine the number of slices per bale to create more consistency. Available on all configurations of LB4 models.

Design Features

More Style. More Substance.

The LB4 series large square baler isn’t just another pretty piece of equipment: It is designed from the ground up for long life and superior performance. On the outside, the unique curved shape allows it to shed crop debris. The baler width has been reduced by 2 feet to improve visibility to the rear and sides of the baler and takes up less space on the road and in the shed. Composite side panels are lighter, rust proof and fade resistant. And underneath that curvy red exterior is an amazing workhorse that has more capacity than its forerunners.

Serviceablity
- Three-stage opening assembly: easy ground-level access to key service points and full visibility of gearbox for routine checks
- Ground-level flywheel brake lever has to be in place before you can raise the shield
- New styling includes a newly designed service platform, which features one level for easy access to key bale chamber service points and knotters
- The foldable ladder provides quick access to the platform and stores easily without being an obstacle.
Operator Visibility
- Narrow sleek design of the LB4 series balers increases operator visibility to the rear and sides of the baler for increased operator efficiency
- Curved shape allows for crop debris to fall off baler for less ingress of debris into knotter assembly and twine storage areas, resulting in less operator maintenance and increased performance
One-Piece Design
- One-piece twine box panels utilize durable thermoform technology
- Composite shields: a one-piece design with automotive seals for minimal debris in twine box and provides easy maintenance and less ingress of debris into twine and knotters
- Front gearbox shield: a composite shield using rotomold technology for lighter weight and durability.
- Choose from either a single-piece roller chute or two-piece roller chute

Drive Option
- Same proven design
- Upgraded primary and secondary drivelines offering increased capacity
- Three-joint design and angle input shaft reinforced reducing vibrations, resulting in better reliability and longer life
Higher-efficiency Flywheel
- Larger diameter high-inertia flywheel, resulting in 48% more energy, smoother operation and increased fuel efficiency.
- Heavier duty components inside the gearbox provides durability and increased strokes per minute from 42 to 48 as well as giving 20% more capacity
Versatility
- Larger tire options provide improved flotation and a lighter footprint
- Choice of three axle configurations: Single, Steered Tandem and Large Steered Tandem

Configurations

Pack it in. And Stack 'em High.

Match your baler to your tractor and then match your bales to your feed, shipping and storage needs. Case IH LB4 series large square balers form bales that stack perfectly and are denser, thanks to things like left and right steering sensors that you can observe through your AFS Pro 700 display and quickly and easily adjust for perfect bale formation. In addition, a removable floor liner adjusts to different crop types. Adjust to your specifications, whether you’re baling for your own livestock or running a commercial hay operation.

Matched Systems
- Suspended roller wind guard with feed-assist roller to efficiently move your crop into the pre-chamber
- Channel Opening is matched to the width of the bale chamber; cutter and pre-compression chamber widths match also
- Results: better capacity, more efficiency and, ultimately, better bale quality
- Heavy-duty pickup reel handles varied crop types, including cornstalks and other tough stubble
The Perfect Finish
- Reduce the risk of twine breakage with drive shaft-driven double knotters
- Increase daily output of dense bales that can stand up to rough handling
- Our best-in-class double knotters have new improved shielding: repositioned fans to keep them clean as well as providing protection and efficient operations
- Reaching the preset bale length engages the knotter system
- Twine moves around the bale as it is formed eliminating stress on knotter components and providing greater reliability to the system and tying cycles
- Dual bale chamber ejector tines offer complete bale clearance and works independently to remove the rearmost bale

Extras That Help You Go the Extra Mile
- Each twine box easily flips up to provide additional clearance for cleanout or maintenance
- Twine storage with 16 balls on each side
- The easy-thread system allows you to keep baling when the conditions are right
- Case IH ThirtyPlus™ hay preservative
- Bales at a higher moisture content without worrying about heating or mold damage resulting in higher-feed-value bales
- For maximum flexibility and bale density, add an optional Case IH rotor cutter
- This system uses a large rotor to feed crop from the pickup through a row of spring-protected knives before entering the compression chamber.
Don't Let the Sunset Stop Your Productivity

Technology Helps you Tie it All Together

The LB4 series baler is no exception when it comes to a built-in AFS experience. The same intuitive easy-to-ready AFS Pro 700 display used with Case IH tractors, combines, sprayers, and planters can control and monitor key parameters on LB4 series balers. A camera feed on the bale chute allows a visual from the cab on every bale as it’s ejected. Monitor bale weight, moisture, and density; flake count and consistency; and detect misties all while recording these important details with each bale drop location. All your data can be seamlessly uploaded to AFS Connect and viewed on the web and mobile experiences offered by Case IH.
