What’s different? The 5 differences that matter most, from the published figures.
- 2026 ZT Avenger has a 1,372 mm (54 in) deck; 2026 Rambler has a 1,067 mm (42 in) deck, a 305 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 ›
- 2026 ZT Avenger lists at A$11,935 to A$12,595; 2026 Rambler lists at A$9,240, a A$2,695 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- 2026 ZT Avenger has Flexible Rubber Side Discharge discharge; 2026 Rambler has Side Discharge discharge.
- 2026 ZT Avenger weighs 338 kg (745 lbs); 2026 Rambler weighs 287 kg (633 lbs), a 51 kg difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What 2026 ZT Avenger's weight means for a trailer ›
- 2026 ZT Avenger has a published top speed of 7 mph; 2026 Rambler has a published top speed of 6 mph, a 1 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
- 2026 ZT Avenger works out to 1.24 ha/hour; 2026 Rambler works out to 0.82 ha/hour, a 0.41 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.
Verified means each manufacturer publishes the figure. A bigger number is only a bigger number; nothing here says which machine is better. The full specification table is below.
