What’s different? The 5 differences that matter most, from the published figures.
- PRO-TURN 672 KAWASAKI EFI has a Fabricated X-Factor® 3 deck; Rebel has a 3 Gauge / 6mm deck.
- PRO-TURN 672 KAWASAKI EFI has a 7 ga deck; Rebel has a 1/4" or 3-Gauge Thick Solid Steel deck.
- PRO-TURN 672 KAWASAKI EFI has a 38.5 hp engine; Rebel has a 31 hp engine, a 7.5 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.
- PRO-TURN 672 KAWASAKI EFI has a 1,829 mm (72 in) deck; Rebel has a 1,549 mm (61 in) deck, a 280 mm 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 ›
- PRO-TURN 672 KAWASAKI EFI has a published top speed of 15 mph; Rebel has a published top speed of 12 mph, a 3 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
