List prices are the manufacturer’s published figures, re-checked daily; they exclude tax, freight and dealer setup.
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.
- Z252KH-54 has a Hydro-Gear ZT-3100 transmission; ZT Avenger has a Dual Hydro Gear 2800 transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.
- Z252KH-54 holds 4.3 gal (16.3 L) of fuel; ZT Avenger holds 7.8 gal (29.5 L) of fuel, a 3.5 gal 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.
- Z252KH-54 has a 10-gauge steel deck; ZT Avenger has a 3/16" or 7-Gauge Thick Solid Steel deck.
- Z252KH-54 has a published top speed of 8 mph; ZT Avenger has a published top speed of 7 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.
- Z252KH-54 weighs 827 lbs (375.2 kg); ZT Avenger weighs 745 lbs (338 kg), a 82 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Z252KH-54's weight means for a trailer ›
