Compare Mowers
These mowers are in different classes — showing only attributes they share.
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.
- Rebel X holds 13 gal (49.2 L) of fuel; Spartan SRT-XD holds 9.5 gal (36 L) of fuel, a 3.5 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.
- Rebel X weighs 1,494 lbs (677.7 kg); Spartan SRT-XD weighs 1,290 lbs (585.1 kg), a 204 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Rebel X's weight means for a trailer ›
- Rebel X cuts from 1 in (25 mm) to 5 in (127 mm); Spartan SRT-XD cuts from 1.5 in (38 mm) to 4.8 in (121 mm). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
- Rebel X has a published top speed of 12 mph; Spartan SRT-XD has a published top speed of 13 mph, a 1 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
- Rebel X works out to 5.9 acres/hour; Spartan SRT-XD works out to 6.4 acres/hour, a 0.5 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.
