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.
- Stander ZK 61 61G8 uses a Briggs & Stratton engine; XC 610 SSi 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.
- Stander ZK 61 61G8 has a published top speed of 12.5 mph; XC 610 SSi has a published top speed of 19 mph, a 6.5 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- Stander ZK 61 61G8 has a 7 Gauge deck; XC 610 SSi has a Fabricated Steel deck.
- Stander ZK 61 61G8 weighs 1,180 lbs (535.2 kg); XC 610 SSi weighs 1,400 lbs (635 kg), a 220 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Stander ZK 61 61G8's weight means for a trailer ›
- Stander ZK 61 61G8 has a 40 hp engine; XC 610 SSi has a 35 hp engine, a 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.
