• Powered by a Kubota 21HP, 3-cylinder diesel engine, generating a high torque rise that easily handles hours of heavy-duty mowing.
  • Kubota’s reputable HST transmission is easily controlled by a single foot pedal and produces a smooth and comfortable ride.
  • Soft-touch power steering enhances manoeuvrability, reduces fatigue, and makes operating the GR2120 effortless.
  • Unlike a belt-drive transmission utilized in conventional mowers, Kubota’s low-maintenance shaft-drive transmission will provide years and years of reliable service.
  • Shaft-drive mower deck and hydraulic PTO clutch deliver reliability with far less maintenance than conventional mowers. No more belts and pulleys to maintain.

Mower Deck

  • 48″ mower deck constructed of durable 10 gauge steel and designed with a 5-inch deep shell for professional and lasting results.
  • Easy to reach cutting height adjustment dial and hydraulic mower deck lift, make achieving professional results easy. For even finer clippings, an optional mulching kit is also available.
  • One-piece unit that’s easy to install, Kubota’s mulch system makes clippings disappear into grass, creating a healthier lawn.
  • Incredibly sturdy yet lightweight, the large-capacity, 350 litre grass catcher lets you mow longer with fewer stops for emptying.


  • Oversized and generously padded, the GR2120’s suspension seat can be adjusted to provide a high level of comfort to a wide range of operators. The full-flat open platform minimizes operator fatigue with plenty of legroom.
  • Weight adjustment dial allows the operator to customise the seat suspension for increased comfort.
  • Height adjustment dial allows the operator to easily and quickly adjust the mower cut height from 1″ to 4″, in 1/4″ increments.
  • Ergonomically positioned to the left of the operator, the hydraulic lever provides simple and effortless lift/ lower operations of the mower deck.
