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

The Bush-Whacker ST-180 Elite flex-wing rotary cutter is a commercial grade 15-foot mower built for demanding roadside, right of way, and large property maintenance. Designed for uneven terrain and heavy cutting conditions, the ST-180 Elite is commonly used by highway maintenance contractors, municipalities, counties, and school systems that mow along freeways, county roads, and public property. It is a proven solution for operations around Mount Pleasant, TX. and Mount Vernon, TX. where consistent roadside mowing helps reduce fire risk and create safer soft shoulders for vehicles.

With a wide 15-foot cutting path and true flex-wing design, the ST-180 Elite allows each mowing section to follow the ground independently. This makes it especially effective for long stretches of roadside, ditches, and embankments near Winnsboro, TX. and Bogata, TX. where uneven terrain is common.

The ST-180 Elite is built off the time-tested T-180 platform and upgraded with a smooth, easy to clean top deck. Its heavy-duty deck construction and reinforced frame are designed to handle daily commercial use, making it a dependable choice for county road crews and municipal operations in Pittsburg, TX. and Daingerfield, TX.

This cutter features a high-capacity divider gearbox and three spindle gearboxes designed to handle demanding workloads. Category 5 constant velocity main driveline and Category 4 wing drivelines provide smooth power transfer, while heavy duty slip clutches protect the driveline when encountering tough material. The ST-180 Elite is rated to cut brush up to 4 inches in diameter, making it well suited for roadside growth control and right of way maintenance.

Hydraulic wing lift allows operators to raise wings for transport or adjust to changing terrain without leaving the tractor seat. The cutter’s ability to maintain a consistent cut across uneven ground helps crews work efficiently while improving visibility and safety along roadways and public spaces in Naples, TX.

The Bush-Whacker ST-180 Elite is ideal for highway mowing contractors, counties, municipalities, and school systems responsible for maintaining large grassy areas. Operators who need a rugged, dependable cutter for roadside mowing, public property maintenance, and fire risk reduction will benefit most from this model.
