Otherwise, the two mowers sport the same basic features, including a 175cc Briggs and Stratton engine, single-lever deck height adjustment and Troy-Bilt's TriAction cutting system.
The TB350 XP's 11" rear wheels allow it to better handle rougher terrain, ensuring improved maneuverability compared to the TB330 XP's standard 8" wheels. Its 175cc Briggs and Stratton engine provides the TB350 XP with efficient, quiet, cool power by way of its overhead valve design. Meanwhile, the TB350 XP's TriAction cutting system ensures smoother, more efficient cutting by way of a rake guard, S-shaped blade and a symmetrical deck that juts out on either side of the mower past the wheels for easier edging.
