2025 Bush-Whacker® Flex-Wing Cutters ST-180 Elite

Bush-Whacker ST-180 Elite Flex-Wing Rotary Cutter

The Bush-Whacker ST-180 Elite flex-wing rotary cutter is a heavy duty 15-foot mower engineered for commercial roadside and large area maintenance. Built to handle uneven terrain, embankments, and dense growth, the ST-180 Elite is widely used by highway mowing contractors, counties, municipalities, and school systems responsible for maintaining roadsides and public properties. It is a trusted option for operations in Mount Pleasant, TX. and Sulphur Springs, TX. where consistent mowing helps improve visibility, reduce fire risk, and create safer roadside conditions.

The true flex-wing design allows each section of the cutter to follow the ground independently, delivering an even cut across ditches and rolling terrain. This makes the ST-180 Elite especially effective for long stretches of highway and county road maintenance near Paris, TX. and Longview, TX.

The ST-180 Elite is built off Bush-Whacker’s proven T-180 platform and upgraded with a smooth top deck that makes cleanup faster and easier. Heavy duty deck construction, reinforced framing, and high quality components allow this cutter to withstand the demands of daily mowing schedules commonly required by county crews and municipal departments in Clarksville, TX.

This cutter is equipped with a high capacity divider gearbox and three spindle gearboxes designed for demanding workloads. A Category 5 constant velocity main driveline and Category 4 wing drivelines provide smooth power transfer, while heavy duty slip clutches help protect the driveline when encountering thick grass or brush. Rated to cut material up to 4 inches in diameter, the ST-180 Elite is well suited for controlling heavy roadside growth.

Hydraulic wing lift allows operators to raise and lower the wings from the tractor seat, improving productivity and safety during transport and operation. Consistent cutting performance helps crews maintain cleaner rights of way and safer soft shoulders along roadways and public access areas around New Boston, TX. and Atlanta, TX.

The Bush-Whacker ST-180 Elite is ideal for highway maintenance contractors, county road departments, municipalities, and school systems tasked with maintaining large grassy areas. Operators who need a rugged, reliable cutter for roadside mowing, right of way maintenance, and public property management will benefit most from this model.
