A side-by-side reference of each model's stated specifications. MowerFacts doesn’t give opinions: where a published, spec-derived rule can separate machines we mark a Data Pick and show the rule; here, read the values and decide what fits your needs.

- S100 Lawn Tractor has a 500 cc (30.5 ci) engine; S140 Lawn Tractor has a 724 cc (44.2 ci) engine, a 224 cc difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
