Parts Compatible with the Kubota GR2100 Garden Tractor

The GR2100 is an 18 horsepower diesel garden tractor in Kubota's GR Series, the entry generation that preceded the current GR2110 / GR2120 lineup. It uses the Kubota D902 era 3-cylinder diesel engine with hydrostatic transmission, paired with a mid-mount mower deck. Customers commonly find GR2100 units still in active service in established residential property maintenance fleets.

The GR2100 shares many service parts with the GR2110, GR2120, and other D902 era Kubota equipment because Kubota engineered the GR Series on a shared parts platform with the D902 engine family.
