What’s different? The 5 differences that matter most, from the published figures.
- Z955R EFIZTrak Zero-Turn Mower has a Hydrostatic transmission; Super S has a Hydro-Gear 12cc pump with Parker TL wheel motors transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.
- Z955R EFIZTrak Zero-Turn Mower holds 11.5 gal (43.5 L) of fuel; Super S holds 7.3 gal (27.6 L) of fuel, a 4.2 gal 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.
- Z955R EFIZTrak Zero-Turn Mower has a published top speed of 12 mph; Super S 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.
- Z955R EFIZTrak Zero-Turn Mower weighs 1,437 lbs (652 kg); Super S weighs 1,207 lbs (547.5 kg), a 230 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Z955R EFIZTrak Zero-Turn Mower's weight means for a trailer ›
- Z955R EFIZTrak Zero-Turn Mower has a 30.5 hp engine; Super S has a 29.5 hp engine, a 1 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.
