Compare Mowers
Prices are the recommended retail prices published by each manufacturer’s Australian site, in AUD, as read on the date shown on each model’s page; dealers set the final price.
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 PRO-STANCE 36 KAWASAKI — commercial: daily paid use and high acreage; 36-inch deck; gas powered
What’s different? The 5 differences that matter most, from the published figures.
- GZD15-3HD has a 10,670 mm (420.1 in) deck; PRO-STANCE 36 KAWASAKI has a 914 mm (36 in) deck, a 9,756 mm 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 ›
- GZD15-3HD uses a Kubota Z602 engine; PRO-STANCE 36 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.
- GZD15-3HD weighs 600 kg (1,323 lbs); PRO-STANCE 36 KAWASAKI weighs 352 kg (776 lbs), a 248 kg difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What GZD15-3HD's weight means for a trailer ›
- GZD15-3HD runs on Diesel; PRO-STANCE 36 KAWASAKI runs on Gas. Fuel type sets what you buy and store; it is not a measure of power.
- GZD15-3HD has Adjustable Dual Lever Steering drive; PRO-STANCE 36 KAWASAKI has Hydro-Gear® ZT-3100® Transaxles drive.
