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.
Best suited for
What each model is built for, from its duty class and key specs. This is a neutral reference — MowerFacts does not rank one model above another.
- Cub Cadet PRO Z 772L — commercial: daily paid use and high acreage; 72-inch deck; gas powered
- Cub Cadet PRO X 648 — commercial: daily paid use and high acreage; 48-inch deck; gas powered
What’s different? The 5 differences that matter most, from the published figures.
- PRO Z 772L has a 72 in (1,829 mm) deck; PRO X 648 has a 48 in (1,219 mm) deck, a 24 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 772L has a 31 hp engine; PRO X 648 has a 22 hp engine, a 9 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 772L lists at $14,599; PRO X 648 lists at $10,799, a $3,800 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- PRO Z 772L has a 61 ci (999 cc) engine; PRO X 648 has a 44.3 ci (726 cc) engine, a 16.7 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
- PRO Z 772L 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.
