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 Gas uses a Kohler engine; 440 EFI uses a Vanguard 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 Gas has a Hydro-Gear® 16cc Pump; Parker® 18ci Wheel Motors transmission; 440 EFI has a G3 Hydrostatic Transmission transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.
- Renegade Gas weighs 1,628 lbs (738.5 kg); 440 EFI weighs 1,320 lbs (598.7 kg), a 308 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Renegade Gas's weight means for a trailer ›
- Renegade Gas has a published top speed of 13 mph; 440 EFI has a published top speed of 11 mph, a 2 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- Renegade Gas holds 13 gal (49.2 L) of fuel; 440 EFI holds 12 gal (45.4 L) of fuel, a 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.
