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.
- Renegade Diesel weighs 1,862 lbs (844.6 kg); IS600 Zero Turn Mower weighs 942 lbs (427.3 kg), a 920 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Renegade Diesel's weight means for a trailer ›
- Renegade Diesel uses a Perkins Diesel engine; IS600 Zero Turn Mower uses a Kawasaki® FS600V engine. The engine maker builds the engine; the mower maker chooses the model, rating and fit, so the badge alone does not settle output or longevity.
- Renegade Diesel holds 13 gal (49.2 L) of fuel; IS600 Zero Turn Mower holds 6 gal (22.7 L) of fuel, a 7 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.
- Renegade Diesel has a 67.1 ci (1,100 cc) engine; IS600 Zero Turn Mower has a 36.8 ci (603 cc) engine, a 30.3 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
- Renegade Diesel has a 24.7 hp engine; IS600 Zero Turn Mower has a 18.5 hp engine, a 6.2 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.
