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.
- ZXT 52 FXT00 uses a Kawasaki engine; Autonomous ZK 72 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.
- ZXT 52 FXT00 has a 52 in (1,321 mm) deck; Autonomous ZK 72 61G8 has a 72 in (1,829 mm) deck, a 20 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 ›
- ZXT 52 FXT00 has a Floating-side discharge deck; Autonomous ZK 72 61G8 has a Floating-Mulch deck.
- ZXT 52 FXT00 weighs 1,491 lbs (676.3 kg); Autonomous ZK 72 61G8 weighs 1,201 lbs (544.8 kg), a 290 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What ZXT 52 FXT00's weight means for a trailer ›
- ZXT 52 FXT00 cuts from 1.5 in (38 mm) to 6 in (152 mm); Autonomous ZK 72 61G8 cuts from 1.5 in (38 mm) to 5.5 in (140 mm). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.

Other verified differences
- ZXT 52 FXT00 has a 38.5 hp engine; Autonomous ZK 72 61G8 has a 40 hp engine, a 1.5 hp difference.
- ZXT 52 FXT00 has a published top speed of 13 mph; Autonomous ZK 72 61G8 has a published top speed of 12.5 mph, a 0.5 mph difference.
Calculated by MowerFacts
- ZXT 52 FXT00 works out to 5.5 acres/hour; Autonomous ZK 72 61G8 works out to 7.3 acres/hour, a 1.8 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.
