GR Series Garden Tractor

The GR series is Kubota's diesel-powered garden tractor lineup, combining the familiar riding mower format with Kubota diesel engines, shaft-driven PTO, and a glide-steer system for exceptional maneuverability. These are premium residential machines for homeowners who want Kubota diesel reliability and a tight turning radius in a traditional tractor-style mower.

🔧

Kubota Diesel Engine

The GR series runs Kubota's own 3-cylinder diesel engines rather than gas alternatives. Diesel delivers more torque for powering through thick or wet grass, uses less fuel, and is built for the kind of longevity that Kubota diesel engines are known for worldwide.

  • •Kubota 3-cylinder diesel: 20 HP (GR2020G) to 21 HP (GR2120)
  • •Diesel torque advantage for thick, heavy grass
  • •Lower fuel consumption than comparable gas engines
  • •Kubota-built engine with proven reliability record
🔄

Glide-Steer System

The GR's Glide-Steer system uses a steering wheel (not lap bars) to deliver zero-turn-style maneuverability. This makes the GR approachable for operators who prefer traditional steering-wheel control but want the tight turning ability of a zero-turn mower.

  • •Steering-wheel control with zero-turn-like turning radius
  • •Familiar operation for owners accustomed to lawn tractors
  • •Smoother turns than lap-bar-controlled zero-turns
  • •Power steering standard for effortless operation
⛓️

Shaft-Driven Mower Deck

Like the ZD and F series, the GR uses a shaft-driven PTO to power the mower deck — no belts. This means consistent blade speed, no belt maintenance, and a cleaner cut that maintains quality throughout the life of the machine.

  • •Shaft-drive PTO eliminates mower deck belts
  • •Consistent blade speed under all mowing conditions
  • •48-inch or 54-inch mower deck options
  • •Side discharge with mulch kit available

What Owners Say

  • •The only diesel-powered garden tractor on the market which gives it incredible fuel economy
  • •Kubota D782 diesel is one of the most proven small engines in the world
  • •4WD and Glide Steer make it handle more like a compact tractor than a garden mower
  • •Premium price but the diesel engine will last far longer than any gas alternative
