Troy-Bilt Bronco 42B2 Riding Lawn Mower

The Troy-Bilt Bronco 42B2 Riding Lawn Mower is a reliable, user-friendly lawn tractor engineered to make residential yard maintenance efficient and comfortable. Powered by a robust 17.5 HP 500cc Briggs & Stratton single-cylinder engine with pressure lubrication, it delivers dependable power to manage lawn sizes up to 1.5 acres. The mower features a foot-pedal controlled Continuously Variable Transmission (CVT) AutoDrive system that operates smoothly like an automatic vehicle, providing seamless speed control without manual shifting.

Constructed with a heavy-duty robotically welded Step-Thru frame, this riding mower allows for easy mounting and dismounting with generous legroom. Its 42-inch 12-gauge stamped steel cutting deck utilizes two blades and features a 5-position height adjustment lever, enabling versatile cutting heights between 1.5 inches and 3.75 inches. Equipped with anti-scalp deck wheels and an 18-inch turning radius, it easily maneuvers around trees, borders, and obstacles while protecting turf from damage. Added operator conveniences include standard headlights, a high-back adjustable seat, vibration-reducing rubber footpads, a deck wash port, and a rear tow hitch for pull-behind attachments.
