John Deere’s “unfair” practices raised repair costs for farmers and kept them from being able to make repairs on tractors and other equipment they own, the Federal Trade Commission (FTC) alleges in a new lawsuit.

In a redacted version of the complaint posted by the FTC, the lawsuit says Deere provides its “Full-Function Service ADVISOR” only to Deere dealers, while making its more limited “Customer Service ADVISOR” available to equipment customers, independent mechanics and others.
