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 uses a Perkins Diesel engine; IS2600 Zero Turn Mower uses a Yanmar™ diesel 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 has a 1/4" or 3-Gauge Thick Solid Steel deck; IS2600 Zero Turn Mower has a iCD™ Cutting System deck.
- Renegade Diesel has a published top speed of 13 mph; IS2600 Zero Turn Mower 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.
- Renegade Diesel weighs 1,862 lbs (844.6 kg); IS2600 Zero Turn Mower weighs 1,606 lbs (728.5 kg), a 256 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 has a 67.1 ci (1,100 cc) engine; IS2600 Zero Turn Mower has a 55.2 ci (904 cc) engine, a 12 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
