What’s different? The 5 differences that matter most, from the published figures.
- ZT HD 52 KAWASAKI has a 52 in (1,321 mm) deck; COMPACT-PRO 34 KAWASAKI has a 34 in (864 mm) deck, a 18 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 ›
- ZT HD 52 KAWASAKI has a 23 hp engine; COMPACT-PRO 34 KAWASAKI has a 15.5 hp engine, a 7.5 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 HD 52 KAWASAKI has a 7 ga deck; COMPACT-PRO 34 KAWASAKI has a 10 ga deck.
- ZT HD 52 KAWASAKI holds 5.1 gal (19.3 L) of fuel; COMPACT-PRO 34 KAWASAKI holds 7.2 gal (27.2 L) of fuel, a 2.1 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.
- ZT HD 52 KAWASAKI lists at $6,949; COMPACT-PRO 34 KAWASAKI lists at $8,099, a $1,150 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
