Force By ABI, Z-23 - RVF Technology 

The heart and soul of the Z-23 is it’s patented Responsive Variable Force Technology. This RVF technology enables a small footprint zero-turn platform to do the work of much larger and heavier equipment, with a fraction of the otherwise required tractive effort. Located at the mid underbelly of the Z-23, the patented RVF Technology hydraulically controls mid-mounted ground-engaging attachments with lift, variable down pressure, and pitch adjustments.
