What’s different? The 5 differences that matter most, from the published figures.
- X730 Signature Series Lawn Tractor weighs 858 lbs (389 kg); S100 Lawn Tractor weighs 414 lbs (187.8 kg), a 444 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What X730 Signature Series Lawn Tractor's weight means for a trailer ›
- X730 Signature Series Lawn Tractor holds 5.2 gal (19.7 L) of fuel; S100 Lawn Tractor holds 2.4 gal (9.1 L) of fuel, a 2.8 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.
- X730 Signature Series Lawn Tractor has a 25.5 hp engine; S100 Lawn Tractor has a 17.5 hp engine, a 8 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.
- X730 Signature Series Lawn Tractor has a K90 hydrostatic integrated with transaxle transmission; S100 Lawn Tractor has a Hydrostatic, 2-wheel drive transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.
- X730 Signature Series Lawn Tractor has a published top speed of 8.5 mph; S100 Lawn Tractor has a published top speed of 5.5 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.
