The Kubota T1400 and T1400H are single-cylinder gasoline lawn tractors built around Kubota's GH400V-L engine, produced from 1987 to 1996 according to TractorData and other secondary sources. The two models are mechanically identical except for the drivetrain: the T1400 uses a gear shift with variable speed drive, while the T1400H uses a hydrostatic transmission. Note that many online spec databases list "the T1400" with hydrostatic transmission specs — per the factory manual, the hydrostatic drive belongs to the T1400H only. All figures below are transcribed directly from the factory manual's specification table unless otherwise noted.
