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’s different? The 3 differences that matter most, from the published figures.
- Spartan RZ-XD Blackout lists at $10,799; Spartan RZ-XD lists at $9,499, a $1,300 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- Spartan RZ-XD Blackout has a 54 in (1,372 mm) deck; Spartan RZ-XD has a 48 in (1,219 mm) deck, a 6 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 ›
- Spartan RZ-XD Blackout has a 25.5 hp engine; Spartan RZ-XD has a 24 hp engine, a 1.5 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.
calculated figures
Calculated by MowerFacts
- Spartan RZ-XD Blackout works out to 3.9 acres/hour; Spartan RZ-XD works out to 3.5 acres/hour, a 0.4 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.
