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.
- 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 ›
- ZT Avenger has a 7 Gauge / 4.5mm deck; 2026 Rambler has a 7 Gauge/4.55mm deck.
- ZT Avenger has a 26 hp engine; 2026 Rambler has a 21.5 hp engine, a 4.5 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.
- ZT Avenger holds 29.5 L (7.8 gal) of fuel; 2026 Rambler holds 22.7 L (6 gal) of fuel, a 6.8 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 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 ZT Avenger's weight means for a trailer ›
