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.
- Revolt (Stand-On) has a 36 in (914 mm) deck; Spartan RT-HD has a 61 in (1,549 mm) deck, a 25 in difference. Deck width sets how much grass each pass covers. Mowing time also depends on ground speed, turns and obstacles, so a wider deck alone does not fix the job's length. Time both decks on your own lawn ›
- Revolt (Stand-On) has a 22 hp engine; Spartan RT-HD has a 37 hp engine, a 15 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.
- Revolt (Stand-On) uses a Kawasaki engine; Spartan RT-HD 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.
- Revolt (Stand-On) weighs 805 lbs (365.1 kg); Spartan RT-HD weighs 1,143 lbs (518.5 kg), a 338 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Revolt (Stand-On)'s weight means for a trailer ›
- Revolt (Stand-On) holds 6.5 gal (24.6 L) of fuel; Spartan RT-HD holds 9.5 gal (36 L) of fuel, a 3 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.
