Compare Mowers
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.

- Exmark Quest S-Series Mower weighs 616 lbs (279.4 kg); Z252KW-54 weighs 860 lbs (390.1 kg), a 244 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Exmark Quest S-Series Mower's weight means for a trailer ›
- Exmark Quest S-Series Mower holds 3 gal (11.4 L) of fuel; Z252KW-54 holds 4.3 gal (16.3 L) of fuel, a 1.3 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.
- Exmark Quest S-Series Mower has a published top speed of 7 mph; Z252KW-54 has a published top speed of 8 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.
