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.
- PRO-STANCE 60 KAWASAKI has a 23.5 hp engine; Stander ZK 61 FX820 has a 34.5 hp engine, a 11 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.
- PRO-STANCE 60 KAWASAKI holds 9 gal (34.1 L) of fuel; Stander ZK 61 FX820 holds 15.5 gal (58.7 L) of fuel, a 6.5 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.
- PRO-STANCE 60 KAWASAKI has a published top speed of 9 mph; Stander ZK 61 FX820 has a published top speed of 12.5 mph, a 3.5 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- PRO-STANCE 60 KAWASAKI has a Fabricated X-Factor® 3 deck; Stander ZK 61 FX820 has a Floating-side discharge deck.
- PRO-STANCE 60 KAWASAKI weighs 940 lbs (426.4 kg); Stander ZK 61 FX820 weighs 1,160 lbs (526.2 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 PRO-STANCE 60 KAWASAKI's weight means for a trailer ›
