The primary ground-breaking advancement that sets the Bourgault eXtended Range harrow series apart from the competition is the patented, in-cab Adjustable Down Force (ADF) system.
This design employs hydraulically controlled down force
or up force
to each harrow section ensuring a uniform field finish even when contouring to the extremes. ADF ensures that the down force of the harrow section:
is constant regardless of contour position,
is isolated from other adjustments, and,
- is easily adjustable via hydraulic pressure.
The ADF can be manually set on the hitch of the harrow, or available with a convenient in-cab 415 Control Box option for on the go adjustments.
