Kubota's signature lawn tractor — Glide Steer turns and a diesel option, built like a small tractor.

Glide Steer is Kubota's steering system on the GR Series that lets the mower deck follow a tighter path than the tractor's own wheels, so you can trim closer around trees, beds, and obstacles without scalping the lawn. It's one of the features that sets the GR apart from a typical lawn tractor.
Yes, the GR Series offers both gas and diesel engine options, which is unusual for a lawn and garden tractor in this class. Diesel costs a bit more up front but tends to pay off in fuel efficiency and longevity for anyone putting on a lot of hours.
The GR Series comes with 48-inch and 54-inch mower decks. For most properties approaching 3 acres, the 54-inch deck cuts mowing time down noticeably.
The GR is built more like a small tractor — it's larger, offers more deck size, adds Glide Steer, and gives you a diesel option, while the T90 is a lighter-duty gas-only lawn tractor for smaller properties. I typically recommend the GR for properties approaching 3 acres, or for customers who want something built to last for years.
It's often called both — Kubota positions it as a lawn and garden tractor because it's built heavier than a typical lawn tractor, with frame construction and steering closer to a compact tractor. That's part of why it holds up well over many years of use.
