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 4 differences that matter most, from the published figures.
- ProLine H600 Direct Collect cuts from 25 mm (1 in) to 90 mm (3.5 in); GZD15-3HD cuts from 102 mm (4 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.
- ProLine H600 Direct Collect has a 18 hp engine; GZD15-3HD has a 15 hp engine, a 3 hp difference. Published horsepower is the maker's rating at a stated engine speed. It is a different measure from displacement, and two engines of equal rating can pull differently.
- ProLine H600 Direct Collect holds 22 L (5.8 gal) of fuel; GZD15-3HD holds 19 L (5 gal) of fuel, a 3 L 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.
- ProLine H600 Direct Collect weighs 635 kg (1,400 lbs); GZD15-3HD weighs 600 kg (1,323 lbs), a 35 kg difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What ProLine H600 Direct Collect's weight means for a trailer ›
