Our verdict
Gravely ZT HD 52
Gravely calls the ZT HD "a residential mower often mistaken for a commercial unit," and the hardware backs that up: a 10-gauge fabricated deck, serviceable ZT-3100 transaxles and a welded frame built low for stability. Cut quality is the highlight here — it's the best in this group. The recurring owner gripes are deck rattle and belt tension, both manageable, and you pay a premium for a 52-inch cut. For a manicured lawn on rolling ground, it's a standout.
