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 high demand roadside and large area maintenance. Designed to handle uneven terrain, embankments, and heavy growth, the ST-180 Elite is widely used by highway maintenance contractors, municipalities, counties, and school systems responsible for mowing rights of way and public property. It is a proven solution for operations in Greenville, TX. and Tyler, TX. where maintaining clean roadsides improves visibility, safety, and fire prevention.

The true flex-wing design allows each mowing section to follow the ground independently, delivering a consistent cut across ditches and rolling terrain. This makes the ST-180 Elite especially effective for long stretches of roadway and large public spaces near Marshall, TX. and Rockwall, TX. where terrain changes frequently.

The ST-180 Elite is engineered for daily commercial use, featuring Bush-Whacker’s heavy duty deck construction and a smooth top deck that simplifies cleanup at the end of long mowing days. Its rugged frame and reinforced components make it a dependable choice for county road departments and municipal crews working around Texarkana, TX.

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

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 safer soft shoulders and cleaner rights of way along highways and public access areas near Broken Bow, OK. and Hugo, OK.

The Bush-Whacker ST-180 Elite is ideal for highway mowing contractors, municipalities, counties, and school systems tasked with maintaining large grassy areas. Operations responsible for public property and roadside mowing around Shreveport, LA. will benefit from its durability, cutting capacity, and ability to perform reliably under daily use.
