3. STIHL RZ 152 Gasoline Zero-Turn Mower has a 25.3 hp engine; Z254FX has a 24 hp engine, a 1.3 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.
4. STIHL RZ 152 Gasoline Zero-Turn Mower lists at $4,500; Z254FX lists at $4,699, a $199 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
5. STIHL RZ 152 Gasoline Zero-Turn Mower has a 52 in (1,321 mm) deck; Z254FX has a 54 in (1,372 mm) deck, a 2 in 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 ›
