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.
- RIDGELINE 48 lists at $6,799; PRO X 660 EFI lists at $12,799, a $6,000 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- RIDGELINE 48 has a 22 hp engine; PRO X 660 EFI has a 34.5 hp engine, a 12.5 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.
- RIDGELINE 48 weighs 719 lbs (326.1 kg); PRO X 660 EFI weighs 1,115 lbs (505.8 kg), a 396 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What RIDGELINE 48's weight means for a trailer ›
- RIDGELINE 48 holds 4.5 gal (17 L) of fuel; PRO X 660 EFI holds 7.5 gal (28.4 L) of fuel, a 3 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.
- RIDGELINE 48 has a published top speed of 7 mph; PRO X 660 EFI has a published top speed of 10 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.
