What’s different? The 5 differences that matter most, from the published figures.
- 400 Series 452 52 in holds 32 L (8.5 gal) of fuel; EDGE 52 KAWASAKI holds 7.6 L (2 gal) of fuel, a 24.4 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.
- 400 Series 452 52 in has a Hydro-2800 with charge pumps - Serviceable transmission; EDGE 52 KAWASAKI has a Hydrostatic transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.
- 400 Series 452 52 in lists at A$11,499; EDGE 52 KAWASAKI lists at A$8,299, a A$3,200 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- 400 Series 452 52 in has a published top speed of 7.5 mph; EDGE 52 KAWASAKI has a published top speed of 6 mph, a 1.5 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- 400 Series 452 52 in weighs 293 kg (646 lbs); EDGE 52 KAWASAKI weighs 249.9 kg (551 lbs), a 43.1 kg difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What 400 Series 452 52 in's weight means for a trailer ›
