At the end of 1989, the smaller models of JD's 1000 series were replaced by the 1100 series models. From the 1155 model onwards, the cutting table was from the new 800 series, where the table length and base incline were adjustable. Similarly, starting with the 1155, the equipment included a cross auger above the grain pan and a new 4-speed transmission. The smallest models, 1133 and 1144, were still mainly produced for the Nordic markets. They remained JD's last small combines. The 1144 also now came with the SG2 cab.
