Square baler L331R

large

Overview

• Large square baler designed for 80 x 90 cm bales with configurable length and density control
• MegaWide™ pickup and MegaTough™ pickup teeth for high-capacity intake
• Integrated moisture sensor and John Deere bale weighing system
• ISOBUS-compatible controls and BalerAssist drivetrain

MegaWide™ pickup with MegaTough™ pickup teeth
The pickup is manufactured by John Deere in Ottumwa, Iowa. A low-profile pickup drum with a large-diameter roller baffle compresses crop against the tines to increase intake efficiency and reduce crop loss.

• 2.2 m (7.2 ft) pickup available on L331R and L341R; tooth-to-tooth width 1.92 m (76 in.); standard or premium component options; eight staggered tooth bars to reduce overload; semi-pneumatic fixed gauge wheels for ground gauging.
• MegaTough pickup teeth offer increased strength and durability; heavy-duty end teeth improve crop retrieval.
• Chain-driven feeding with mechanical cutout clutch protection for durability.

Premium MegaWide™ pickup
Optional premium pickup upgrades include larger cams, cam bearings, and larger spider gears with bearings to extend service life and reduce noise during operation.

Double-tie knotter system
Gear- and driveline-driven double-tie knotters provide consistent knotting under high density and challenging conditions. Knotters feature integrated auto-lube, grease ports, and accessible adjustment screws.

• Integrated auto-lube in knotter frames with two internal grease ports to lower pre-baling maintenance.
• Split knotter frame mounted to intermittent gear for removal without servicing the knotter stack.
• Sealed gear tensioners for consistent twine tension; twine stored in single-row boxes routed to sealed tensioners.

Connection point and lube line reductions (knotter system)
L331 — Connection points reduced: 8
L341 — Connection points reduced: 12
L331 — Lube line reduction: 16.8 m (55 ft)
L341 — Lube line reduction: 25.3 m (83 ft)

Knotter trip system
The knotter trip is driven by gearbox and driveline to maintain needle-to-plunger timing with hardened cast-iron components. The gearbox rotates the system around 360° to complete ties. Two trip options are available: mechanical or electrical. The electrical trip enables bale-length adjustment and final-bale tie-off from the cab, reduces maintenance, improves length accuracy, and provides predictive tie functions.

Baler monitor and ISOBUS compatibility
ISOBUS-compatible control works with ISOBUS monitors and John Deere GreenStar displays. Features include user-selectable main screens, direction arrows for uniform bales, electronic knotter flags, status feedback (flywheel brake/precutter/greasing/lighting/bale chute/bale drop), and display of bale weight and moisture when equipped. Bale counts selectable by field/customer/season/lifetime.

Moisture sensor
Integrated moisture sensor mounted forward in the bale chamber provides real-time bale moisture readings during baling and can interface with the preservative system to adjust application rates.

Weighing system
John Deere bale weighing system measures bale weight flake-by-flake via sensors on the pre-compression chamber floor and displays current and prior bale weights on the monitor to support consistent bale production.

Preservative applicator
Optional factory-installed preservative system supports harvesting at higher moisture to reduce spoilage risk. Key elements: 567 L (150 U.S. gal.) poly tank, 12-V diaphragm pump, integration with John Deere electronics, ExactApply™ nozzles, and crop-detection sensors to apply preservative only when crop is present.

BalerAssist drivetrain system
Hydraulic drivetrain control enabling forward and reverse at two speeds each direction (up to ~4 plunger strokes/min). Benefits include faster plug removal, reduced maintenance time, and slower cycles for improved knotter troubleshooting. Controlled via ISOBUS display or included Bluetooth remote (functions: enable, slow/fast forward, slow/fast reverse, service lights).
