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.
- Masport ZTM 42 — residential: typical home lawns; 42-inch deck; gas powered
- Masport ZTM 50 — prosumer: larger home properties and light acreage; 50-inch deck; gas powered
What’s different? The 4 differences that matter most, from the published figures.
- ZTM 42 has a 17 hp engine; ZTM 50 has a 23 hp engine, a 6 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.
- ZTM 42 has a 1,070 mm (42.1 in) deck; ZTM 50 has a 1,270 mm (50 in) deck, a 200 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 ›
- ZTM 42 lists at A$6,299; ZTM 50 lists at A$7,299, a A$1,000 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- ZTM 42 weighs 237 kg (522 lbs); ZTM 50 weighs 249 kg (549 lbs), a 12 kg difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What ZTM 42's weight means for a trailer ›
calculated figures and what isn’t comparable
Calculated by MowerFacts
- ZTM 42 works out to 0.77 ha/hour; ZTM 50 works out to 0.91 ha/hour, a 0.14 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.
