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.
- Bad Boy Mowers Rebel — commercial: daily paid use and high acreage; 61-inch deck; gas powered

What’s different? The 5 differences that matter most, from the published figures.
- Rebel has a 3 Gauge / 6mm deck; PRO-TURN 360 KAWASAKI FX850 EFI has a Fabricated X-Factor® 3 deck.
- Rebel has a 1/4" or 3-Gauge Thick Solid Steel deck; PRO-TURN 360 KAWASAKI FX850 EFI has a 7 ga deck.
- Rebel has a published top speed of 12 mph; PRO-TURN 360 KAWASAKI FX850 EFI has a published top speed of 11 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.
- Rebel has a 31 hp engine; PRO-TURN 360 KAWASAKI FX850 EFI has a 29.5 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.
- Rebel has a 50.2 ci (822 cc) engine; PRO-TURN 360 KAWASAKI FX850 EFI has a 52 ci (852 cc) engine, a 1.8 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
