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.

What’s different? The 5 differences that matter most, from the published figures.
- Stander B 32 FX600E has a 32 in (813 mm) deck; Autonomous ZK 61 61G8 has a 61 in (1,549 mm) deck, a 29 in difference. Deck width sets how much grass each pass covers. Mowing time also depends on ground speed, turns and obstacles, so a wider deck alone does not fix the job's length. Time both decks on your own lawn ›
- Stander B 32 FX600E has a 19 hp engine; Autonomous ZK 61 61G8 has a 40 hp engine, a 21 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.
- Stander B 32 FX600E holds 5 gal (18.9 L) of fuel; Autonomous ZK 61 61G8 holds 15.5 gal (58.7 L) of fuel, a 10.5 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.
- Stander B 32 FX600E weighs 703 lbs (318.9 kg); Autonomous ZK 61 61G8 weighs 1,310 lbs (594.2 kg), a 607 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Stander B 32 FX600E's weight means for a trailer ›
- Stander B 32 FX600E uses a Kawasaki engine; Autonomous ZK 61 61G8 uses a Briggs & Stratton 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.

Calculated by MowerFacts
- Stander B 32 FX600E works out to 1.8 acres/hour; Autonomous ZK 61 61G8 works out to 6.2 acres/hour, a 4.3 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.
Verified means each manufacturer publishes the figure. A bigger number is only a bigger number; nothing here says which machine is better. The full specification table is below.
