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.
- Spartan Shield-HD uses a Kawaski engine; Z232KW-42 uses a Kawasaki FR651V 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.
- Spartan Shield-HD cuts from 1 in (25 mm) to 5 in (127 mm); Z232KW-42 cuts from 1.5 in (38 mm) to 4.3 in (108 mm). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
- Spartan Shield-HD holds 5 gal (18.9 L) of fuel; Z232KW-42 holds 3.6 gal (13.6 L) of fuel, a 1.4 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.
- Spartan Shield-HD has a published top speed of 8 mph; Z232KW-42 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.
- Spartan Shield-HD weighs 719 lbs (326.1 kg); Z232KW-42 weighs 643 lbs (291.7 kg), a 76 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Spartan Shield-HD's weight means for a trailer ›
