John Deere Z320M Zero-Turn Mower vs Troy-Bilt Mustang 42 Zero-Turn Mower
Buy the John Deere Z320M if you want the better cut, stronger engine and higher owner satisfaction; its 21.5 hp V-twin and Accel Deep deck are a clear step up over the Troy-Bilt's single-cylinder 547 cc engine. The Troy-Bilt Mustang 42 is the sensible pick if you want a true zero-turn at the lower end of the class, with a welded frame, Hydro-Gear EZT-2200 transmissions and a lifetime frame warranty. Owners rate the Deere higher (4.9 vs 4.1), and the gap reflects real differences in engine smoothness, deck finish and resale.
- Choose the John Deere Z320M if you mow up to 2 acres, want a V-twin engine that runs smoother under load, and value a deeper stamped deck that leaves a cleaner cut.
- Choose the Troy-Bilt Mustang 42 if you want a basic zero-turn for a smaller lawn and prefer the longer frame warranty and simpler single-cylinder engine.
