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 X 648 lists at $10,799; Vertex S-Series (48 in) lists at $13,199, a $2,400 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 published top speed of 10 mph; Vertex S-Series (48 in) has a published top speed of 8.5 mph, a 1.5 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 cuts from 1.5 in (38 mm) to 4.5 in (114 mm); Vertex S-Series (48 in) cuts from 1.5 in (38 mm) to 5 in (127 mm). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
- PRO X 648 weighs 1,015 lbs (460.4 kg); Vertex S-Series (48 in) weighs 925 lbs (419.6 kg), a 90 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What PRO X 648's weight means for a trailer ›
- PRO X 648 has a 22 hp engine; Vertex S-Series (48 in) has a 23.5 hp engine, a 1.5 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.
