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.
Best suited for
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.
- Kubota ZD1011-48 — commercial: daily paid use and high acreage; 48-inch deck
- Walker Walker Model C19 — commercial: daily paid use and high acreage; 48-inch deck; gas powered
What’s different? The 5 differences that matter most, from the published figures.
- ZD1011-48 uses a Kubota D782-E4-ZD-3 engine; Walker Model C19 uses a Rehlko 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.
- ZD1011-48 weighs 1,296 lbs (587.9 kg); Walker Model C19 weighs 762 lbs (345.6 kg), a 534 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What ZD1011-48's weight means for a trailer ›
- ZD1011-48 has a published top speed of 9 mph; Walker Model C19 has a published top speed of 6.5 mph, a 2.5 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- ZD1011-48 holds 6 gal (22.7 L) of fuel; Walker Model C19 holds 4 gal (15.1 L) of fuel, a 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.
- ZD1011-48 has a 47.5 ci (778 cc) engine; Walker Model C19 has a 41.1 ci (674 cc) engine, a 6.3 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
calculated figures and what isn’t comparable
Calculated by MowerFacts
- ZD1011-48 works out to 3.5 acres/hour; Walker Model C19 works out to 2.5 acres/hour, a 1.0 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.
Not comparable
- Drive System: not published for Walker Model C19.
- Cut height range: not published for ZD1011-48.
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.
