List prices are the manufacturer’s published figures, re-checked daily; they exclude tax, freight and dealer setup.
A side-by-side reference of each model's stated specifications. MowerFacts doesn’t give opinions: where a published, spec-derived rule can separate machines we mark a Data Pick and show the rule; here, read the values and decide what fits your needs.

What’s different? The 5 differences that matter most, from the published figures.
- ZT HD 52 KAWASAKI has a 7 ga deck; MZ 54 ROPS Special Edition has a Steel deck.
- ZT HD 52 KAWASAKI has Side discharge; MZ 54 ROPS Special Edition has Collect/Mulch/Side discharge discharge.
- ZT HD 52 KAWASAKI cuts from 1.5 in (38 mm) to 5 in (127 mm); MZ 54 ROPS Special Edition cuts from 1.5 in (38 mm) to 4.5 in (114 mm). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
- ZT HD 52 KAWASAKI has a published top speed of 8 mph; MZ 54 ROPS Special Edition has a published top speed of 8.5 mph, a 0.5 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- ZT HD 52 KAWASAKI has a 52 in (1,321 mm) deck; MZ 54 ROPS Special Edition has a 54 in (1,372 mm) deck, a 2 in difference. Deck width sets how much grass each pass covers. Mowing time also depends on ground speed, turns and obstacles, so a wider deck alone does not fix the job's length. Time both decks on your own lawn ›
