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.
- 400 Series 442 42 in holds 32 L (8.5 gal) of fuel; 2026 Rambler holds 22.7 L (6 gal) of fuel, a 9.3 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.
- 400 Series 442 42 in has a published top speed of 7.5 mph; 2026 Rambler has a published top speed of 6 mph, a 1.5 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- 400 Series 442 42 in lists at A$9,999; 2026 Rambler lists at A$9,240, a A$759 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- 400 Series 442 42 in weighs 277 kg (611 lbs); 2026 Rambler weighs 287 kg (633 lbs), a 10 kg difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What 400 Series 442 42 in's weight means for a trailer ›
- 400 Series 442 42 in cuts from 25 mm (1 in) to 102 mm (4 in); 2026 Rambler cuts from 38 mm (1.5 in) to 114 mm (4.5 in). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
