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 each model is built for, from its duty class and key specs. This is a neutral reference — MowerFacts does not rank one model above another.
- Spartan Spartan RT-Pro — commercial: daily paid use and high acreage; 61-inch deck; gas powered
- Altoz XE 610 SS — commercial: daily paid use and high acreage; 61-inch deck; gas powered
What’s different? The 4 differences that matter most, from the published figures.
- Spartan RT-Pro has a published top speed of 11 mph; XE 610 SS has a published top speed of 9 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.
- Spartan RT-Pro weighs 1,099 lbs (498.5 kg); XE 610 SS weighs 970 lbs (440 kg), a 129 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 cuts from 1.5 in (38 mm) to 4.8 in (121 mm); XE 610 SS cuts from 1.5 in (38 mm) to 4.3 in (108 mm). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
- Spartan RT-Pro holds 9.5 gal (36 L) of fuel; XE 610 SS holds 10 gal (37.9 L) of fuel, a 0.5 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.
calculated figures and what isn’t comparable
Calculated by MowerFacts
- Spartan RT-Pro works out to 5.4 acres/hour; XE 610 SS works out to 4.4 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.
