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 X 648 — commercial: daily paid use and high acreage; 48-inch deck; gas powered
- Cub Cadet PRO X 434 — commercial: daily paid use and high acreage; 34-inch deck; gas powered
What’s different? The 5 differences that matter most, from the published figures.
- PRO X 648 uses a Kawasaki® engine; PRO X 434 uses a Kohler® engine. The engine maker builds the engine; the mower maker chooses the model, rating and fit, so the badge alone does not settle output or longevity.
- PRO X 648 lists at $10,799; PRO X 434 lists at $7,299, a $3,500 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- PRO X 648 has a 48 in (1,219 mm) deck; PRO X 434 has a 34 in (864 mm) deck, a 14 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 X 648 has a published top speed of 10 mph; PRO X 434 has a published top speed of 7 mph, a 3 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- PRO X 648 holds 7.5 gal (28.4 L) of fuel; PRO X 434 holds 5.4 gal (20.4 L) of fuel, a 2.1 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.
