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.
- Walker Walker Model H24d — commercial: daily paid use and high acreage; 60-inch deck
- Exmark Vertex S-Series (60 in) — commercial: daily paid use and high acreage; 60-inch deck; gas powered
What’s different? The 5 differences that matter most, from the published figures.
- Walker Model H24d uses a Rehlko engine; Vertex S-Series (60 in) uses a Kawasaki FX730V 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.
- Walker Model H24d has a 62.7 ci (1,028 cc) engine; Vertex S-Series (60 in) has a 44.3 ci (726 cc) engine, a 18.4 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
- Walker Model H24d has a published top speed of 10 mph; Vertex S-Series (60 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.
- Walker Model H24d holds 9.4 gal (35.6 L) of fuel; Vertex S-Series (60 in) holds 8 gal (30.3 L) of fuel, a 1.4 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.
- Walker Model H24d cuts from 1 in (25 mm) to 5 in (127 mm); Vertex S-Series (60 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.
