What’s different? The 3 differences that matter most, from the published figures.
- S170 Lawn Tractor has a K46 heavy-duty hydrostatic, two-wheel drive transmission; S140 Lawn Tractor has a TLT200 hydrostatic, two-wheel drive transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.
- S170 Lawn Tractor has a 24 hp engine; S140 Lawn Tractor has a 22 hp engine, a 2 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.
- S170 Lawn Tractor weighs 503 lbs (228.2 kg); S140 Lawn Tractor weighs 468 lbs (212.3 kg), a 35 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What S170 Lawn Tractor's weight means for a trailer ›
