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.
- ZT6100 Zero-Turn Mower holds 15 gal (56.8 L) of fuel; ZT2000 Zero-Turn Mower holds 3.8 gal (14.4 L) of fuel, a 11.2 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.
- ZT6100 Zero-Turn Mower weighs 1,464 lbs (664.1 kg); ZT2000 Zero-Turn Mower weighs 717 lbs (325.2 kg), a 747 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What ZT6100 Zero-Turn Mower's weight means for a trailer ›
- ZT6100 Zero-Turn Mower has a published top speed of 12 mph; ZT2000 Zero-Turn Mower has a published top speed of 7 mph, a 5 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- ZT6100 Zero-Turn Mower has a 61 in (1,549 mm) deck; ZT2000 Zero-Turn Mower has a 42 in (1,067 mm) deck, a 19 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 ›
- ZT6100 Zero-Turn Mower has a HG ZT-4400 Hydrostatic Transaxles transmission; ZT2000 Zero-Turn Mower has a HG ZT-2800 Hydrostatic Transaxles transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.

- ZT6100 Zero-Turn Mower works out to 5.9 acres/hour; ZT2000 Zero-Turn Mower works out to 2.4 acres/hour, a 3.5 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.
