Designed for Versatile Forage Baling

The 504 Pro G4 combines variable-chamber bale formation with a wide pickup to support efficient collection of windrows. Its 75 double rubber-mounted pickup teeth are designed to gather crop across the pickup opening, while hydraulic pickup lift and spring-assisted gauge wheels help provide operating flexibility. The 17-knife chopping system adds processing capability for forage applications where chopped material is preferred.

Bale size can be selected across the 36- to 60-inch diameter range, allowing operators to match bale dimensions to crop conditions, handling preferences, and storage requirements. The baler has a maximum bale weight of 2,400 pounds (1,088.6 kg), depending on crop and operating conditions.

Control and Bale-Handling Equipment

The Atlas Pro control system uses a 7-inch color touchscreen for managing bale-related functions. Bale-shape indicators are standard, and the net gauge and net-tension control are operated through the control system. Standard rear-load netwrap and extra-roll net storage support the baling workflow, while the spring-loaded bale ramp assists with bale release after formation.
