- Cox Stockman PLUS 40 in — residential: typical home lawns; 40-inch deck; gas powered
What’s different? The 5 differences that matter most, from the published figures.
- S100 Lawn Tractor has a Hydrostatic, 2-wheel drive transmission; Stockman PLUS 40 in has a Hydrostatic with Auto Locking Diff transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.
- S100 Lawn Tractor cuts from 25 mm (1 in) to 102 mm (4 in); Stockman PLUS 40 in cuts from 20 mm (0.8 in) to 75 mm (3 in). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
- S100 Lawn Tractor has a 500 cc (30.5 ci) engine; Stockman PLUS 40 in has a 586 cc (35.8 ci) engine, a 86 cc difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
- S100 Lawn Tractor has a 1,067 mm (42 in) deck; Stockman PLUS 40 in has a 1,016 mm (40 in) deck, a 51 mm difference. Deck width sets how much grass each pass covers. Mowing time also depends on ground speed, turns and obstacles, so a wider deck alone does not fix the job's length. Time both decks on your own lawn ›
- S100 Lawn Tractor has a 17.5 hp engine; Stockman PLUS 40 in has a 18 hp engine, a 0.5 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.
