- Z554L has a published top speed of 12 mph; PRO-STANCE 52 KAWASAKI has a published top speed of 9 mph, a 3 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- Z554L has Collect/Mulch/Side discharge discharge; PRO-STANCE 52 KAWASAKI has Side discharge.
- Z554L holds 45.4 L (12 gal) of fuel; PRO-STANCE 52 KAWASAKI holds 34.1 L (9 gal) of fuel, a 11.4 L 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.
