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.
Best suited for
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.
- Scag Cheetah II — 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.
- Cheetah II uses a Vanguard BIG BLOCK engine; Rebel X uses a Kawasaki engine. The engine maker builds the engine; the mower maker chooses the model, rating and fit, so the badge alone does not settle output or longevity.
- Cheetah II has a published top speed of 16 mph; Rebel X has a published top speed of 12 mph, a 4 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- Cheetah II has a 36 hp engine; Rebel X has a 38.5 hp engine, a 2.5 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.
- Cheetah II weighs 1,392 lbs (631.4 kg); Rebel X weighs 1,494 lbs (677.7 kg), a 102 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Cheetah II's weight means for a trailer ›
- Cheetah II cuts from 1.3 in (32 mm) to 5 in (127 mm); Rebel X cuts from 1 in (25 mm) to 5 in (127 mm). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
calculated figures and what isn’t comparable
