Compare Mowers
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.
- PRO Z 754S holds 14.9 gal (56.4 L) of fuel; PRO X 648 holds 7.5 gal (28.4 L) of fuel, a 7.4 gal 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.
- PRO Z 754S lists at $14,699; PRO X 648 lists at $10,799, a $3,900 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- PRO Z 754S has a 27 hp engine; PRO X 648 has a 22 hp engine, a 5 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.
- PRO Z 754S has a published top speed of 12 mph; PRO X 648 has a published top speed of 10 mph, a 2 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- PRO Z 754S has a 54 in (1,372 mm) deck; PRO X 648 has a 48 in (1,219 mm) deck, a 6 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 ›

- PRO Z 754S has a 52 ci (852 cc) engine; PRO X 648 has a 44.3 ci (726 cc) engine, a 7.7 ci difference.
Calculated by MowerFacts
- PRO Z 754S works out to 5.2 acres/hour; PRO X 648 works out to 3.9 acres/hour, a 1.4 acres/hour difference. Calculated by MowerFacts from deck width and the published top speed at 80% efficiency; it is not a manufacturer figure, and real mowing is slower.
