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.
- IS600 Zero Turn Mower lists at $9,294; Turf Tiger II lists at $16,999 to $25,399, a $7,705 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- IS600 Zero Turn Mower holds 6 gal (22.7 L) of fuel; Turf Tiger II holds 12 gal (45.4 L) of fuel, a 6 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.
- IS600 Zero Turn Mower weighs 942 lbs (427.3 kg); Turf Tiger II weighs 1,418 lbs (643.2 kg), a 476 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What IS600 Zero Turn Mower's weight means for a trailer ›
- IS600 Zero Turn Mower has a 18.5 hp engine; Turf Tiger II has a 26 hp engine, a 7.5 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.
- IS600 Zero Turn Mower cuts from 1.5 in (38 mm) to 4.5 in (114 mm); Turf Tiger II cuts from 1.5 in (38 mm) to 6 in (152 mm). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
