What’s different? The 5 differences that matter most, from the published figures.
- ZT XL 42 KAWASAKI holds 13.2 L (3.5 gal) of fuel; 2026 Rambler holds 22.7 L (6 gal) of fuel, a 9.5 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.
- ZT XL 42 KAWASAKI has a Fabricated X-Factor® deck; 2026 Rambler has a 7 Gauge/4.55mm deck.
- ZT XL 42 KAWASAKI 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.
- ZT XL 42 KAWASAKI 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.
- ZT XL 42 KAWASAKI weighs 306.2 kg (675 lbs); 2026 Rambler weighs 287 kg (633 lbs), a 19.2 kg difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What ZT XL 42 KAWASAKI's weight means for a trailer ›
