Many Iowa farmers hire some custom machine work in their farm business or perform custom work for others. Others rent machinery or perform other services. The Iowa Farm Custom Rate Survey was mailed to 323 people by the U.S. Postal Service and 133 people via e-mail in early February 2018. The information below is based on 124 responses and 4,043 custom rates provided by Iowa farmers, custom operators, and farm managers. Thirteen percent of the respondents perform custom work, 23 percent hire work done, 42 percent indicated doing both, three percent indicated doing none, and 19 percent did not indicate whether they perform or hire custom work.
