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 4 differences that matter most, from the published figures.
- Spartan RT-HD uses a Vanguard engine; Spartan RT-Pro uses a Kawasaki 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.
- Spartan RT-HD has a 37 hp engine; Spartan RT-Pro has a 24 hp engine, a 13 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.
- Spartan RT-HD lists at $12,899; Spartan RT-Pro lists at $8,799, a $4,100 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- Spartan RT-HD weighs 1,143 lbs (518.5 kg); Spartan RT-Pro weighs 1,099 lbs (498.5 kg), a 44 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Spartan RT-HD's weight means for a trailer ›
