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’s different? The 5 differences that matter most, from the published figures.
- 400 Series 442-D 42 in holds 32 L (8.5 gal) of fuel; ZTM 42 holds 11.4 L (3 gal) of fuel, a 20.6 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-D 42 in uses a Kawasaki engine; ZTM 42 uses a Masport 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.
- 400 Series 442-D 42 in lists at A$8,999; ZTM 42 lists at A$6,299, a A$2,700 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- 400 Series 442-D 42 in has a Hydro-Gear ZT2200 transmission; ZTM 42 has a Hydro-Gear EZT (ZT-2200) transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.
- 400 Series 442-D 42 in has a published top speed of 7.5 mph; ZTM 42 has a published top speed of 5.6 mph, a 1.9 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.

Calculated by MowerFacts
- 400 Series 442-D 42 in works out to 1.02 ha/hour; ZTM 42 works out to 0.77 ha/hour, a 0.25 ha/hour difference. Calculated by MowerFacts from deck width and the published top speed at 80% efficiency; it is not a manufacturer figure, and real mowing is slower.
