Designed for tractors with 55-80 PTO HP, it features a 78-inch cutting width and a maximum side extension of 135 inches from the tractor’s centerline to the outermost cutting edge. Its vertical rotation range of -70° to +90° makes it suitable for roadside slopes, riverbanks, and expansive farmlands.

Adjustable skids and a rear roller with a self-cleaning scraper allow for precise cutting height adjustments, while CE-compliant safety shrouds and a bi-directional hydraulic lock enhance operator safety. Backed by a 2-year warranty, the TANK-78 is an ideal solution for demanding vegetation management tasks.
