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 X 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.
- 125VB lists at $8,760; ZT X 42 KAWASAKI lists at $4,299, a $4,461 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- 125VB uses a Briggs & Stratton engine; ZT X 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.
- 125VB holds 3 gal (11.4 L) of fuel; ZT X 42 KAWASAKI holds 3.5 gal (13.2 L) of fuel, a 0.5 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.
- 125VB weighs 700 lbs (317.5 kg); ZT X 42 KAWASAKI weighs 667 lbs (302.6 kg), a 33 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What 125VB's weight means for a trailer ›
- 125VB has a 41 in (1,041 mm) deck; ZT X 42 KAWASAKI has a 42 in (1,067 mm) deck, a 1 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 ›
