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 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.
- Hustler Turf Super SF — commercial: daily paid use and high acreage; 60-inch deck; gas powered
- Hustler Turf Diesel Z — commercial: daily paid use and high acreage; 72-inch deck
What’s different? The 5 differences that matter most, from the published figures.
- Super SF uses a Kawasaki FX1000 EFI engine; Diesel Z uses a Perkins 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.
- Super SF has a 38.5 hp engine; Diesel Z has a 25 hp engine, a 13.5 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.
- Super SF has a published top speed of 15 mph; Diesel Z has a published top speed of 11.5 mph, a 3.5 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- Super SF has a 60 in (1,524 mm) deck; Diesel Z has a 72 in (1,829 mm) deck, a 12 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 ›
- Super SF cuts from 2 in (51 mm) to 5.5 in (140 mm); Diesel Z 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.

- Super SF weighs 1,450 lbs (657.7 kg); Diesel Z weighs 1,711 lbs (776.1 kg), a 261 lbs difference.
- Super SF has a 61 ci (999 cc) engine; Diesel Z has a 69 ci (1,130 cc) engine, a 8 ci difference.
- Super SF holds 13.9 gal (52.6 L) of fuel; Diesel Z holds 14.4 gal (54.5 L) of fuel, a 0.5 gal difference.
Calculated by MowerFacts
- Super SF works out to 7.3 acres/hour; Diesel Z works out to 6.7 acres/hour, a 0.6 acres/hour difference. Calculated by MowerFacts from deck width and the published top speed at 80% efficiency; it is not a manufacturer figure, and real mowing is slower.
Verified means each manufacturer publishes the figure. A bigger number is only a bigger number; nothing here says which machine is better. The full specification table is below.
