What’s different? The 5 differences that matter most, from the published figures.
- Super 104 has a Danfoss DDC20 pumps with Parker TG wheel motors transmission; Z998R DieselZTrak Zero-Turn Mower 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.
- Super 104 has a 60.6 ci (993 cc) engine; Z998R DieselZTrak Zero-Turn Mower has a 95.7 ci (1,568 cc) engine, a 35.1 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
- Super 104 holds 15 gal (56.8 L) of fuel; Z998R DieselZTrak Zero-Turn Mower holds 12 gal (45.4 L) of fuel, a 3 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.
- Super 104 weighs 2,500 lbs (1,134 kg); Z998R DieselZTrak Zero-Turn Mower weighs 2,925 lbs (1,326.8 kg), a 425 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Super 104's weight means for a trailer ›
- Super 104 has a 40 hp engine; Z998R DieselZTrak Zero-Turn Mower has a 43.4 hp engine, a 3.4 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.
