the Norden Accumulators

Bale accumulators are machines that arrange bales into groups and situate them on the ground. A grapple mounted on a loader retrieves the grouped bales.
Norden Mfg Bale Accumulators for small square bales have a simple design and automatically arrange the bales into groups. They then automatically place the hay or straw bales on the ground when the group is complete.
