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’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 32 KAWASAKI has a 813 mm (32 in) deck, a 9,857 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 cuts from 102 mm (4 in) to 127 mm (5 in); PRO-STANCE 32 KAWASAKI cuts from 38 mm (1.5 in) to 127 mm (5 in). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
- GZD15-3HD uses a Kubota Z602 engine; PRO-STANCE 32 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 32 KAWASAKI weighs 345.6 kg (762 lbs), a 254.4 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 32 KAWASAKI runs on Gas. Fuel type sets what you buy and store; it is not a measure of power.
