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’s different? The 5 differences that matter most, from the published figures.
- 337G5 EFI/ETC lists at $15,195; 125V lists at $8,760, a $6,435 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- 337G5 EFI/ETC uses a Vanguard engine; 125V uses a Rehlko 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.
- 337G5 EFI/ETC holds 13 gal (49.2 L) of fuel; 125V holds 6.5 gal (24.6 L) of fuel, a 6.5 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.
- 337G5 EFI/ETC has a Hydro-Gear ZT-4400 Transmission transmission; 125V 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.
- 337G5 EFI/ETC has a 61 in (1,549 mm) deck; 125V has a 48 in (1,219 mm) deck, a 13 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 ›
