In 1984, Allis-Chalmers faced significant challenges and was acquired by Deutz. Following the acquisition, Deutz rebranded the Allis tractors as Deutz-Allis and started importing Deutz-Fahr tractors under this new name. The lawn and garden tractors manufactured by Simplicity continued to be produced in the Deutz-Allis green until Allis was sold again, leading to the establishment of AGCO.
