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.
- Cheetah II lists at $13,999 to $18,999; 440 EFI lists at $18,955, a $4,956 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- Cheetah II has a published top speed of 16 mph; 440 EFI has a published top speed of 11 mph, a 5 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; 440 EFI has a 40 hp engine, a 4 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 holds 13 gal (49.2 L) of fuel; 440 EFI holds 12 gal (45.4 L) of fuel, a 1 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.
- Cheetah II weighs 1,392 lbs (631.4 kg); 440 EFI weighs 1,320 lbs (598.7 kg), a 72 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 ›

Other verified differences
- Cheetah II cuts from 1.3 in (32 mm) to 5 in (127 mm); 440 EFI cuts from 1 in (25 mm) to 5 in (127 mm).
Calculated by MowerFacts
- Cheetah II works out to 7.9 acres/hour; 440 EFI works out to 5.4 acres/hour, a 2.5 acres/hour difference. Calculated by MowerFacts from deck width and the published top speed at 80% efficiency; it is not a manufacturer figure, and real mowing is slower.
