Key Features at a Glance

Work Faster in More Conditions

The camless pickup allows higher operating speeds across a wide range of crops and moisture levels. Five tine bars with close spacing capture more crop for uniform, well-shaped bales.

Cleaner, More Durable Pickup

Longer, thicker, and more flexible tines — plus offset end tines — ensure consistent crop flow into the augers, reducing losses and extending service life.

Complete In-Cab Control

The Bale Control Pro monitor, standard on XtraCut models, has a large, bright touchscreen that clearly shows baler settings and functions. Integrated ISOBUS lets you run the baler from a single in-cab terminal.

Precision Cutting Capability

The XtraCut™ knife system lets you select 0, 8, 9, or all 17 knives for forage cuts as short as 2.65 inches, ideal for silage, stover, or hay.

Perfect Bale Density

Set bale size and pressure from the cab. The Constant Pressure System keeps density even from core to edge, and four continuous belts give maximum traction for dense, uniform bales every time.
