Designed for Flexible Bale Production

The 604 Pro G4 uses a variable bale chamber to accommodate a broad range of bale diameters, from compact 36-inch bales through full-size 72-inch bales. The 48-inch bale width provides a consistent finished-bale format, while the rear-load netwrap system supports efficient bale tying during repetitive baling operations.

The camless wide pickup is 73 inches wide from tooth to tooth and 78 inches across the outside flare. Its 75 double rubber-mounted teeth are supported by flotation gauge wheels with spring assist, helping the pickup follow field contours. Hydraulic pickup lift further supports convenient operation when entering, leaving, or moving between working areas.

Controls and Bale Handling

An Atlas Pro control system with a 7-inch color touchscreen provides the machine control interface. The spring-loaded bale ramp is included in this configuration and supports bale discharge after formation. Together, the netwrap system, bale ramp, and variable chamber are intended to streamline the cycle from windrow pickup through bale formation and unloading.

Tractor Requirements

The 604 Pro G4 requires a tractor with a minimum PTO rating of 90 hp (67.1 kW). Vermeer recommends a tractor rated at 120 hp (89.5 kW) for this baler. This configuration uses a 540-rpm PTO driveline. The baler has a hydraulic pickup lift; additional hydraulic flow and pressure requirements are not published in the consulted manufacturer catalogue sources.
