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 623T — commercial: daily paid use and high acreage; 48-inch deck; gas powered
- Bad Boy Mowers Maverick HD — commercial: daily paid use and high acreage; 48-inch deck; gas powered
What’s different? The 5 differences that matter most, from the published figures.
- 623T holds 4 gal (15.1 L) of fuel; Maverick HD holds 12.9 gal (49 L) of fuel, a 8.9 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.
- 623T uses a Rehlko engine; Maverick HD uses a Kawasaki 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.
- 623T has a T-Drive Transmission transmission; Maverick HD has a Dual Hydro Gear 3400 transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.
- 623T has a 42.4 ci (694 cc) engine; Maverick HD has a 45.6 ci (747 cc) engine, a 3.2 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
- 623T has a published top speed of 8.5 mph; Maverick HD has a published top speed of 9 mph, a 0.5 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
calculated figures and what isn’t comparable
Calculated by MowerFacts
- 623T works out to 3.3 acres/hour; Maverick HD works out to 3.5 acres/hour, a 0.2 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.
