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.
- T2290KWNC-42 uses a Kawasaki FR651V engine; GR2020G uses a Kohler CH640 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.
- T2290KWNC-42 has a Hydro-Gear T3HD transmission; GR2020G has a Kubota HST transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.
- T2290KWNC-42 weighs 622 lbs (282.1 kg); GR2020G weighs 882 lbs (400.1 kg), a 260 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What T2290KWNC-42's weight means for a trailer ›
- T2290KWNC-42 has a 42 in (1,067 mm) deck; GR2020G has a 48 in (1,219 mm) deck, a 6 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 ›
- T2290KWNC-42 holds 3.6 gal (13.6 L) of fuel; GR2020G holds 4.2 gal (15.9 L) of fuel, a 0.6 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.
