What’s different? The 5 differences that matter most, from the published figures.
- PRO-TURN 48 KAWASAKI FX has a Fabricated X-Factor® 3 deck; Spartan RZ-XD has a 5" Deep, Reinforced 7 Gauge Full-Floating Deck deck.
- PRO-TURN 48 KAWASAKI FX 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.
- PRO-TURN 48 KAWASAKI FX 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.
- PRO-TURN 48 KAWASAKI FX weighs 965 lbs (437.7 kg); Spartan RZ-XD weighs 907 lbs (411.4 kg), a 58 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What PRO-TURN 48 KAWASAKI FX's weight means for a trailer ›
- PRO-TURN 48 KAWASAKI FX holds 10 gal (37.9 L) of fuel; Spartan RZ-XD holds 9.5 gal (36 L) of fuel, a 0.5 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.
