Troy-Bilt Bronco 42 Riding Lawn Tractor 106.7cm 19 HP Briggs & Stratton
The Troy-Bilt Bronco 42 is a riding lawn tractor built around a 19 HP 540cc Briggs & Stratton Intek engine with a pressure-lubrication system, paired with a 42-inch twin-blade cutting deck that covers ground quickly and leaves an even finish. Its AutoDrive transmission works like a car's, so speed and direction are managed with simple foot-pedal controls rather than a manual gear lever.
Five cutting height positions let you adapt the deck to changing lawn conditions, while anti-scalp deck wheels help protect turf on uneven ground. The step-thru frame makes getting on and off easier, an 18-inch turning radius helps you work around trees and beds, and the mid-back seat with rubber anti-vibration footpads keeps longer mowing sessions comfortable. A rear hitch accepts optional baggers, mulching kits, aerators, dump carts and sprayers.
