During the Gilded Age what were the primary complaints of farmers?

Falling price.

High-Interest rates.

Rail-road owners

Explanation:

Agriculture prices were expensive, cattle farming was expensive, and their land was destroyed are three major problems they faced after the Civil War. They addressed the expensive prices by switching to crop farming (plants/tobacco/cotton, etc.) and they had high interest rates with the banks. They also faced very high railroad prices to transport their goods and therefore boycotted this method of transportation.
