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 400D — commercial: daily paid use and high acreage; 61-inch deck
- Grasshopper 125VB — commercial: daily paid use and high acreage; 41-inch deck; gas powered
What’s different? The 5 differences that matter most, from the published figures.
- 400D lists at $20,460; 125VB lists at $8,760, a $11,700 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- 400D holds 12 gal (45.4 L) of fuel; 125VB holds 3 gal (11.4 L) of fuel, a 9 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.
- 400D uses a Kubota engine; 125VB uses a Briggs & Stratton engine. The engine maker builds the engine; the mower maker chooses the model, rating and fit, so the badge alone does not settle output or longevity.
- 400D has a 61 in (1,549 mm) deck; 125VB has a 41 in (1,041 mm) deck, a 20 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 ›
- 400D has a G3 Hydrostatic Transmission transmission; 125VB has a Parker HTE Transmission transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.
