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 has a 29.5 hp engine; WB700 Walk-Behind Mower has a 14.5 hp engine, a 15 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.
- ZT6100 Zero-Turn Mower has a 61 in (1,549 mm) deck; WB700 Walk-Behind Mower has a 36 in (914 mm) deck, a 25 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 holds 15 gal (56.8 L) of fuel; WB700 Walk-Behind Mower holds 5 gal (18.9 L) of fuel, a 10 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); WB700 Walk-Behind Mower weighs 773 lbs (350.6 kg), a 691 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; WB700 Walk-Behind Mower has a published top speed of 6.5 mph, a 5.5 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
