What’s different? The 5 differences that matter most, from the published figures.
- ZT 42 KAWASAKI holds 7.6 L (2 gal) of fuel; IKON 42 KAWASAKI holds 13.2 L (3.5 gal) of fuel, a 5.7 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.
- ZT 42 KAWASAKI has Hydro-Gear® Serviceable EZT® Transaxles drive; IKON 42 KAWASAKI has Hydro-Gear® EZT® Transaxles drive.
- ZT 42 KAWASAKI weighs 225.9 kg (498 lbs); IKON 42 KAWASAKI weighs 296.6 kg (654 lbs), a 70.8 kg difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What ZT 42 KAWASAKI's weight means for a trailer ›
- ZT 42 KAWASAKI has a 18 hp engine; IKON 42 KAWASAKI has a 21.5 hp engine, a 3.5 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 42 KAWASAKI has a published top speed of 6 mph; IKON 42 KAWASAKI has a published top speed of 7 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.
