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.
- ZT3000 Zero-Turn Mower has a published top speed of 8 mph; Walker Model C19 has a published top speed of 6.5 mph, a 1.5 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- ZT3000 Zero-Turn Mower has a 20 hp engine; Walker Model C19 has a 19 hp engine, a 1 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.
- ZT3000 Zero-Turn Mower has a 44.3 ci (726 cc) engine; Walker Model C19 has a 41.1 ci (674 cc) engine, a 3.2 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
- ZT3000 Zero-Turn Mower cuts from 1.5 in (38 mm) to 4.8 in (121 mm); Walker Model C19 cuts from 1 in (25 mm) to 4 in (102 mm). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
- ZT3000 Zero-Turn Mower holds 3.8 gal (14.4 L) of fuel; Walker Model C19 holds 4 gal (15.1 L) of fuel, a 0.2 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.
