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.
- Grasshopper 325D — commercial: daily paid use and high acreage; 52-inch deck
- Grasshopper 400D — commercial: daily paid use and high acreage; 61-inch deck
What’s different? The 2 differences that matter most, from the published figures.
- 325D has a G2 Hydrostatic Transmission transmission; 400D has a G3 Hydrostatic Transmission transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.
- 325D has a 52 in (1,321 mm) deck; 400D has a 61 in (1,549 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 ›

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.
