What’s different? The 5 differences that matter most, from the published figures.
- GR2120-54 uses a Kubota D782 engine; T2290KWT-48 uses a Kawasaki GH739V-3 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.
- GR2120-54 has a HST, Shaft Drive transmission; T2290KWT-48 has a Hydro-Gear G730 transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.
- GR2120-54 weighs 440 kg (970 lbs); T2290KWT-48 weighs 300 kg (661 lbs), a 140 kg difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What GR2120-54's weight means for a trailer ›
- GR2120-54 runs on Diesel; T2290KWT-48 runs on Petrol. Fuel type sets what you buy and store; it is not a measure of power.
- GR2120-54 has 4 w/Cruise control drive; T2290KWT-48 has 4Wheels-2WD drive.
