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.

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 3 differences that matter most, from the published figures.
- SO34.5KW has a T6 Drive Transmission transmission; SO27KW has a T-Drive Transmission transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.
- SO34.5KW has a 61 in (1,549 mm) deck; SO27KW has a 52 in (1,321 mm) deck, a 9 in 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 ›
- SO34.5KW has a 50.2 ci (822 cc) engine; SO27KW has a 52 ci (852 cc) engine, a 1.8 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
Verified means each manufacturer publishes the figure. A bigger number is only a bigger number; nothing here says which machine is better. The full specification table is below.
