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 4 differences that matter most, from the published figures.
- Spartan RT-Pro lists at $8,799; Spartan SRT-XD lists at $15,299, a $6,500 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- Spartan RT-Pro has a 24 hp engine; Spartan SRT-XD has a 38.5 hp engine, a 14.5 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-Pro weighs 1,099 lbs (498.5 kg); Spartan SRT-XD weighs 1,290 lbs (585.1 kg), a 191 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Spartan RT-Pro's weight means for a trailer ›
- Spartan RT-Pro has a published top speed of 11 mph; Spartan SRT-XD has a published top speed of 13 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.
calculated figures and what isn’t comparable
Calculated by MowerFacts
- Spartan RT-Pro works out to 5.4 acres/hour; Spartan SRT-XD works out to 6.4 acres/hour, a 1.0 acres/hour difference. Calculated by MowerFacts from deck width and the published top speed at 80% efficiency; it is not a manufacturer figure, and real mowing is slower.
