Our take on the Troy Bilt Bronco 46B 17.5hp Briggs Engine 46" Riding Lawn Mower #13AN78BTA66

The Troy-Bilt Bronco 46B is a riding lawn mower with a 46-inch side-discharge steel deck and a 17.5 HP Briggs & Stratton engine. It has a foot-pedal AutoDrive transmission with speeds up to 5.5 MPH, a mid-back adjustable seat, and a Step-Thru frame for easy mounting. An AGM battery provides reliable starting. It suits homeowners with up to an acre or two of flat to gently sloping lawn who want a simple, comfortable rider. Compared with other entry-level riders, it offers a larger deck and engine than many 42-inch models, but lacks a hydrostatic transmission and cruise control found on some rivals.
