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 5 differences that matter most, from the published figures.
- HD PRO 48 KAWASAKI FT holds 5.1 gal (19.3 L) of fuel; Spartan RZ-XD holds 9.5 gal (36 L) of fuel, a 4.4 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.
- HD PRO 48 KAWASAKI FT has a Fabricated X-Factor® 3 deck; Spartan RZ-XD has a 5" Deep, Reinforced 7 Gauge Full-Floating Deck deck.
- HD PRO 48 KAWASAKI FT has a published top speed of 8 mph; Spartan RZ-XD has a published top speed of 9 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.
- HD PRO 48 KAWASAKI FT has a 22 hp engine; Spartan RZ-XD has a 24 hp engine, a 2 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.
- HD PRO 48 KAWASAKI FT lists at $8,799; Spartan RZ-XD lists at $9,499, a $700 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
