Abstract
Apparatus adapted for attachment to a conventional lift device such as a forklift or an end loader, or the like, includes a pair of movable side arms each attached to a respective end of a cross member. Each side arm has attached thereto a respective engaging member for engaging lateral ribs of a first seed box for lifting the seed box. The apparatus further includes a pivoting connection for rotating the first seed box to an inverted orientation for positioning on a second seed box in a nested configuration for storage. The first seed box may also be positioned on the second seed box in a stacked configuration for receiving and storing seed by engaging and lifting the first seed box, rotating the first seed box to an upright orientation, and placing the first seed box on the second seed box.
