Square bales

The most popular size for these small "square" bales was 14" x 18" by 36" long weighing between 70 and 80 pounds, depending on moisture content. Normal baling rates range from 5 to 10 tons per hour. In good baling conditions (heavy windrows and high near optimum moisture content), leaf loss at the pickup and in the bale chamber should be less than four percent.   Small Rectangular Bales were the most common bale type for alfalfa in Oklahoma for many years.
