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.
Best suited for
What each model is built for, from its duty class and key specs. This is a neutral reference — MowerFacts does not rank one model above another.
- Husqvarna Z345 54 in — prosumer: larger home properties and light acreage; 54-inch deck; gas powered
- Husqvarna MZ54 ROPS — commercial: daily paid use and high acreage; 54-inch deck
What’s different? The 4 differences that matter most, from the published figures.
- Z345 54 in lists at $5,599; MZ54 ROPS lists at $6,399, a $800 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- Z345 54 in holds 4.3 gal (16.3 L) of fuel; MZ54 ROPS holds 5 gal (18.9 L) of fuel, a 0.7 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.
- Z345 54 in has a published top speed of 8 mph; MZ54 ROPS has a published top speed of 8.5 mph, a 0.5 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- Z345 54 in has a 23.1 hp engine; MZ54 ROPS has a 24 hp engine, a 0.9 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.
calculated figures and what isn’t comparable
Calculated by MowerFacts
- Z345 54 in works out to 3.5 acres/hour; MZ54 ROPS works out to 3.7 acres/hour, a 0.2 acres/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.
