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 Lazer Z Diesel (LZS 60 in) — commercial: daily paid use and high acreage; 60-inch deck
What’s different? The 5 differences that matter most, from the published figures.
- Walker Model H24d uses a Rehlko engine; Lazer Z Diesel (LZS 60 in) uses a Yanmar 3TNV80FT 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 holds 9.4 gal (35.6 L) of fuel; Lazer Z Diesel (LZS 60 in) holds 12 gal (45.4 L) of fuel, a 2.6 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); Lazer Z Diesel (LZS 60 in) cuts from 1 in (25 mm) to 5.5 in (140 mm). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
- Walker Model H24d has a published top speed of 10 mph; Lazer Z Diesel (LZS 60 in) has a published top speed of 11 mph, a 1 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 has a 23.7 hp engine; Lazer Z Diesel (LZS 60 in) has a 25 hp engine, a 1.3 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.
