No matter the need, the occupation or the bale size you prefer, Challenger has a baler that’s perfectly sized for your feeding style, transportation method or storage facility.

The newest choice of professional hay producers and contractors, Challenger LB Series balers feature more than just an industry-leading design. They offer everything customers have been looking for in a big rectangular baler. That’s particularly true of the new “B” Series models, which feature advanced technology from the pickup assembly to the bale chute…and 10 to 30 percent more capacity than the original LB Series balers.

• An on-board hydraulic system permits easier hook-up and ensures that variables in tractor hydraulic systems will not affect baler performance.
• True bale density is measured through load cells on the plunger connecting rods rather than gearbox deflection.
• An increase in the number of sealed and tapered bearings means fewer service points and a 50-hour service interval.
• The streamlined, one-piece side shields seal the twine boxes when closed to reduce crop build-up.
• Redesigned twine boxes hold up to 30 balls of twine at a 30-degree angle for greater capacity and easier loading.
• The option to produce silage bales or precut bales is available on two of three models.
• A state-of-the-art, control and monitoring system expands your management opportunities that comply to ISO standards.

Big balers that are big on productivity

All LB Series large rectangular balers feature unitized, welded box-beam construction with high-strength steel mainframe, axles, hitch and main components to resist twisting. These balers are equipped with large flotation tires that reduce compaction.

• The LB Series’ drive system is equally reliable, for less downtime, lower maintenance costs and greater resale value.
• An equal-angle driveline and swivel ball drawbar hitch allows short turns with minimal driveline vibration.
• Five simple chain drives perform all operating functions, for greater reliability and less maintenance.
• The packer drive and the pickup drive are slip clutch protected, while the stuffer drive, knotter assemblies and needle drive are shear bolt protected.
• An AutoLube knotter-lube system, which is adjustable from the in-cab monitor to match crop and field conditions, reduces  knotter maintenance.
• A rugged, dual-reduction (LB33B and LB34B) or triple-reduction (LB44B) gearbox is standard in all gearboxes, which now features higher speed for greater capacity,  transmits power from the tractor PTO to the baler without the need for extra chain drives and maintenance.
• A heavy, stress-relieved flywheel, which incorporates an overrunning clutch and adjustable slip clutch, helps maintain plunger momentum, while reducing vibration and shock loads to the tractor.

How it works

Challenger LB Series balers use a pre-charge chamber to pre-form the crop into uniform flakes from top to bottom, regardless of windrow size or baler speed. Uniform flakes make a square shouldered, better-stacking bale.

• As the crop is lifted by the pickup, centering augers assist in feed material to the packer. A set of packer fingers mounted on a crankshaft feeds the crop into the pre-charge chamber. A set of holding fingers retain the charge in the pre-chamber until the density reaches a predetermined level.
• The holding fingers retract and the stuffer latch is tripped. A set of stuffer forks engage o sweep the preformed flake into the bale chamber.
• The plunger sweeps the pre-formed flake of hay off the stuffer forks on the compression stroke and compresses it forming the bale.
