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 4 differences that matter most, from the published figures.
- PRO-STANCE ULTRA 60 FX1000 EFI has a published top speed of 12.5 mph; Super SF has a published top speed of 15 mph, a 2.5 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- PRO-STANCE ULTRA 60 FX1000 EFI holds 16 gal (60.6 L) of fuel; Super SF holds 13.9 gal (52.6 L) of fuel, a 2.1 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.
- PRO-STANCE ULTRA 60 FX1000 EFI cuts from 1.5 in (38 mm) to 5.5 in (140 mm); Super SF cuts from 2 in (51 mm) to 5.5 in (140 mm). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
- PRO-STANCE ULTRA 60 FX1000 EFI weighs 1,364 lbs (618.7 kg); Super SF weighs 1,450 lbs (657.7 kg), a 86 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What PRO-STANCE ULTRA 60 FX1000 EFI's weight means for a trailer ›
