6.2 CHAIN PITCH AND ROD CONFIGURATIONS
The belted chain comes in various pitches, configurations and patterns. These options will help to increase or decrease soil
elimination, maximize conveying capacity, and protect potatoes from damage.
In the figures below, the circles represent the rods in a belted chain. The center to center distance between the rods defines
the chain pitch. The “A” measurement represents the opening between the rods that dictate the size of objects such as
clods, stones and small potatoes to be removed.
Use rod configurations in straight, offset up and offset down, “patterns” to accomplish a purpose based on field conditions.
The belt web dimensions are low profile, 60mm (2.36”) wide with 3 ply’s of polyester nylon. This web design provides the
combination of strength and flexibility required for all applications.
