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.

- PRO-STANCE 48 KAWASAKI holds 9 gal (34.1 L) of fuel; Vertex S-Series (48 in) holds 8 gal (30.3 L) of fuel, a 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.
- PRO-STANCE 48 KAWASAKI weighs 875 lbs (396.9 kg); Vertex S-Series (48 in) weighs 925 lbs (419.6 kg), a 50 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What PRO-STANCE 48 KAWASAKI's weight means for a trailer ›
