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 TrimStar — 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.
- TrimStar weighs 695 lbs (315.2 kg); Diesel Z weighs 1,711 lbs (776.1 kg), a 1,016 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What TrimStar's weight means for a trailer ›
- TrimStar holds 3.4 gal (12.9 L) of fuel; Diesel Z holds 14.4 gal (54.5 L) of fuel, a 11 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.
- TrimStar uses a Kawasaki FS691 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.
- TrimStar has a published top speed of 6.3 mph; Diesel Z has a published top speed of 11.5 mph, a 5.2 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- TrimStar cuts from 1.5 in (38 mm) to 4.5 in (114 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.

Calculated by MowerFacts
- TrimStar works out to 3.1 acres/hour; Diesel Z works out to 6.7 acres/hour, a 3.6 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.
