What’s different? The 5 differences that matter most, from the published figures.
- 2026 Magnum holds 22.7 L (6 gal) of fuel; 400 Series 448 48 in holds 32 L (8.5 gal) of fuel, a 9.3 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.
- 2026 Magnum has a published top speed of 6 mph; 400 Series 448 48 in has a published top speed of 7.5 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.
- 2026 Magnum has a 21.5 hp engine; 400 Series 448 48 in has a 23 hp engine, a 1.5 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.
- 2026 Magnum lists at A$10,340 to A$10,835; 400 Series 448 48 in lists at A$10,999, a A$659 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- 2026 Magnum weighs 299 kg (659 lbs); 400 Series 448 48 in weighs 285 kg (628 lbs), a 14 kg difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What 2026 Magnum's weight means for a trailer ›

Other verified differences
- 2026 Magnum cuts from 38 mm (1.5 in) to 114 mm (4.5 in); 400 Series 448 48 in cuts from 25 mm (1 in) to 102 mm (4 in).
Calculated by MowerFacts
- 2026 Magnum works out to 0.94 ha/hour; 400 Series 448 48 in works out to 1.17 ha/hour, a 0.23 ha/hour difference. Calculated by MowerFacts from deck width and the published top speed at 80% efficiency; it is not a manufacturer figure, and real mowing is slower.
