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.

- Gravely ZT XL 42 KAWASAKI — commercial: daily paid use and high acreage; 42-inch deck; gas powered
What’s different? The 5 differences that matter most, from the published figures.
- 525V lists at $11,595; ZT XL 42 KAWASAKI lists at $5,499, a $6,096 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- 525V uses a Briggs & Stratton engine; ZT XL 42 KAWASAKI uses a Kawasaki® 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.
- 525V weighs 935 lbs (424.1 kg); ZT XL 42 KAWASAKI weighs 675 lbs (306.2 kg), a 260 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What 525V's weight means for a trailer ›
- 525V has Belt Driven drive; ZT XL 42 KAWASAKI has Hydro-Gear® ZT-2800® Transaxles drive.
- 525V has a published top speed of 8 mph; ZT XL 42 KAWASAKI has a published top speed of 7 mph, a 1 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
