- EDGE 52 KAWASAKI holds 7.6 L (2 gal) of fuel; ZT X 52 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.

- EDGE 52 KAWASAKI lists at A$8,299; ZT X 52 KAWASAKI lists at A$10,399, a A$2,100 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- EDGE 52 KAWASAKI weighs 249.9 kg (551 lbs); ZT X 52 KAWASAKI weighs 315.2 kg (695 lbs), a 65.3 kg difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What EDGE 52 KAWASAKI's weight means for a trailer ›
- EDGE 52 KAWASAKI has a published top speed of 6 mph; ZT X 52 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.
