Deere's compact tractors come from Augusta, Georgia, a factory that started in 1990 with a compact utility tractor, passed its millionth tractor in 2014 and builds the 1, 2, 3 and 4 families for North America and export. Unlike Kubota, Deere does not make these small diesels: the compacts run Yanmar engines (the 1025R's is a Yanmar 3TNV80F). The 5 family on this page is the step into utility tractors proper.
The first digit is the frame family and the letter is the trim. E models are the plainer builds (the 3E runs about 9.3 gpm of hydraulics), R models the premium chassis with stronger hydraulics, a heavier hitch and more electronics, and M models sit between, as the 4M does with an open station and a standard PowrReverser. D is the gear-drive economy line: the 3025D, 3035D and 3043D arrived in June 2019 to undercut Deere's own hydrostatics. The small end is being renamed. In February 2026 Deere announced redesigned model year 2027 1 Series tractors, the 1E 23, 1M 25 and 1R 25, taking over from the 1023E, 1025R and 2025R; the 1M 25 and 1R 25 can now be ordered with a factory HVAC cab and come with tilt steering, and all three get a hood that opens to 77 degrees.
Every 1, 2R, 3 and 4 family tractor from 22.4 to 65.9 engine hp carries a 6 year or 2,000 hour powertrain warranty, whichever comes first, for residential and commercial use, over a 2 year or 2,000 hour basic warranty. That matches Kubota's compact term and caps hours where Kioti's does not.
Fit and finish come up more often than raw numbers. The AutoConnect drive-over mower deck on the 1 and 2 families is the feature most often named as the reason to pay more, and 3E owners describe buying frame and weight, not horsepower, while staying under the 25 hp line with no particulate filter. The objection is price: a Kioti or LS of the same horsepower usually lists more loader and hitch for less money, and the long-running argument over whether the 2025R was worth about $3,000 more than a 1025R shows how carefully a Deere buyer has to read the brand's own price ladder.
