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 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.

What’s different? The 5 differences that matter most, from the published figures.
- T2290KWTNC-48 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.
- T2290KWTNC-48 has a hydrostatic 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.
- T2290KWTNC-48 weighs 661 lbs (299.8 kg); GR2020G weighs 882 lbs (400.1 kg), a 221 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What T2290KWTNC-48's weight means for a trailer ›
- T2290KWTNC-48 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.
- T2290KWTNC-48 has a 44.3 ci (726 cc) engine; GR2020G has a 38.1 ci (624 cc) engine, a 6.2 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.

- T2290KWTNC-48 works out to 2.6 acres/hour; GR2020G works out to 2.4 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.
Not comparable
- Deck Material: not published for T2290KWTNC-48.
- Cut height range: not published for GR2020G.
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.
