Compare Mowers
List prices are the manufacturer’s published figures, re-checked daily; they exclude tax, freight and dealer setup.
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.
Best suited for
What each model is built for, from its duty class and key specs. This is a neutral reference — MowerFacts does not rank one model above another.

What’s different? The 5 differences that matter most, from the published figures.
- TS 120 42 in runs on Petrol; S100 Lawn Tractor runs on Gasoline. Fuel type sets what you buy and store; it is not a measure of power.
- TS 120 42 in has a 19 hp engine; S100 Lawn Tractor has a 17.5 hp engine, a 1.5 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.
- TS 120 42 in has a 33 ci (540.8 cc) engine; S100 Lawn Tractor has a 30.5 ci (500 cc) engine, a 2.5 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
- TS 120 42 in has a published top speed of 5.2 mph; S100 Lawn Tractor has a published top speed of 5.5 mph, a 0.3 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- TS 120 42 in holds 2.5 gal (9.5 L) of fuel; S100 Lawn Tractor holds 2.4 gal (9.1 L) of fuel, a 0.1 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.
calculated figures and what isn’t comparable
Calculated by MowerFacts
- TS 120 42 in works out to 1.8 acres/hour; S100 Lawn Tractor works out to 1.9 acres/hour, a 0.1 acres/hour difference. Calculated by MowerFacts from deck width and the published top speed at 80% efficiency; it is not a manufacturer figure, and real mowing is slower.
