Troy-Bilt Bronco 42 Riding Lawn Mower – 547cc Engine, AutoDrive™

Troy-Bilt Bronco 42" Riding Mower – Step-Thru Design

Mowing your lawn shouldn’t feel exhausting—or frustrating. If climbing onto your mower is uncomfortable and uneven cuts ruin the look of your yard, it’s time to upgrade to a smarter, easier way to mow.

The Troy-Bilt® Bronco™ 42 Riding Lawn Mower is designed for homeowners who want comfort, control, and dependable power in one easy-to-use machine. Built for lawns up to 1.5 acres, the Bronco™ 42 turns mowing into a smooth, stress-free experience.

Getting on and off the mower is effortless thanks to Troy-Bilt’s Step-Thru™ frame design—no awkward climbing required. Once seated, the adjustable mid-back seat and rubber footpads reduce vibration and fatigue, keeping you comfortable even during longer mowing sessions.

Under the hood, a 547cc Troy-Bilt® engine delivers reliable power to handle thick grass, uneven terrain, and light slopes with ease. It starts smoothly and maintains consistent performance, so you can focus on getting the job done—not fighting your mower.

The 42-inch twin-blade steel cutting deck provides a clean, even cut across your lawn. Two anti-scalp wheels help prevent turf damage on uneven ground, while the side-discharge system efficiently manages grass clippings.

Speed and control come naturally with the AutoDrive™ foot-pedal transmission. There’s no shifting or complicated controls—just press the pedal to move and release to stop. Reach mowing speeds up to 5.5 MPH and finish faster with less effort. Built-in automatic LED headlights turn on when light levels drop, allowing you to mow safely in early mornings or evenings.

For added peace of mind, the Bronco™ 42 is backed by a 3-year limited warranty, so you can mow confidently season after season.
