WICHITA, Kan. (AP) -- The Association of Equipment Manufacturers reports that retail sales of farm tractors and combines have grown in January in the United States.

The industry group reported Tuesday that farmers bought more than 11,163 tractors last month. That is up 20.3 percent compared to the same month in 2012.

Also higher than normal are sales of combines with 538 sold in January. That is up nearly 21 percent compared to the same month the previous year.

January is typically a slow month for farm equipment sales. Farm equipment sales usually spike in April and October.
