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.

What’s different? The 5 differences that matter most, from the published figures.
- Diesel Z weighs 1,711 lbs (776.1 kg); FasTrak SDX weighs 944 lbs (428.2 kg), a 767 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Diesel Z's weight means for a trailer ›
- Diesel Z uses a Perkins engine; FasTrak SDX uses a Kawasaki FX730 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.
- Diesel Z holds 14.4 gal (54.5 L) of fuel; FasTrak SDX holds 8.5 gal (32.2 L) of fuel, a 5.9 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.
- Diesel Z cuts from 1 in (25 mm) to 5.5 in (140 mm); FasTrak SDX cuts from 1.5 in (38 mm) to 4.5 in (114 mm). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
- Diesel Z has a 69 ci (1,130 cc) engine; FasTrak SDX has a 44.3 ci (726 cc) engine, a 24.7 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.

Calculated by MowerFacts
- Diesel Z works out to 6.7 acres/hour; FasTrak SDX works out to 4.8 acres/hour, a 1.8 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.
