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.
- John Deere Z965R EFIZTrak Zero-Turn Mower — commercial: daily paid use and high acreage; 60-inch deck; gas powered
- Hustler Turf Super SF — commercial: daily paid use and high acreage; 60-inch deck; gas powered
What’s different? The 4 differences that matter most, from the published figures.
- Z965R EFIZTrak Zero-Turn Mower has a published top speed of 12 mph; Super SF has a published top speed of 15 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.
- Z965R EFIZTrak Zero-Turn Mower cuts from 1 in (25 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.
- Z965R EFIZTrak Zero-Turn Mower has a 33 hp engine; Super SF has a 38.5 hp engine, a 5.5 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.
- Z965R EFIZTrak Zero-Turn Mower holds 11.5 gal (43.5 L) of fuel; Super SF holds 13.9 gal (52.6 L) of fuel, a 2.4 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.
