What’s different? The 5 differences that matter most, from the published figures.
- Stockman PRO 40 in has a Hydrostatic with Auto Locking Diff 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.
- Stockman PRO 40 in has a 24 hp engine; S100 Lawn Tractor has a 17.5 hp engine, a 6.5 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.
- Stockman PRO 40 in has a 679 cc (41.4 ci) engine; S100 Lawn Tractor has a 500 cc (30.5 ci) engine, a 179 cc difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
- Stockman PRO 40 in weighs 230 kg (507 lbs); S100 Lawn Tractor weighs 187.8 kg (414 lbs), a 42.2 kg difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Stockman PRO 40 in's weight means for a trailer ›
- Stockman PRO 40 in cuts from 20 mm (0.8 in) to 75 mm (3 in); S100 Lawn Tractor cuts from 25 mm (1 in) to 102 mm (4 in). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
