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 Hydro-Gear® ZT-3100® Transaxles drive; Z252KW-54 has Belt drive.
- ZT HD 52 KAWASAKI holds 19.3 L (5.1 gal) of fuel; Z252KW-54 holds 16.3 L (4.3 gal) of fuel, a 3 L difference. Tank size bounds how long a machine runs between stops. Consumption varies with engine, load and speed, so hours per tank are not fixed.
- ZT HD 52 KAWASAKI weighs 370.6 kg (817 lbs); Z252KW-54 weighs 390.1 kg (860 lbs), a 19.5 kg difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What ZT HD 52 KAWASAKI's weight means for a trailer ›
- ZT HD 52 KAWASAKI has a 1,321 mm (52 in) deck; Z252KW-54 has a 1,372 mm (54 in) deck, a 51 mm 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 ›
- ZT HD 52 KAWASAKI has a 23 hp engine; Z252KW-54 has a 24 hp engine, a 1 hp difference. Published horsepower is the maker's rating at a stated engine speed. It is a different measure from displacement, and two engines of equal rating can pull differently.
