Abstract
An agricultural disk gang includes an elongated disk gang bolt having a threaded end with an externally threaded surface. A plurality of cultivating disks are supported on the disk gang bolt. A nut is threadably engaged with the externally threaded surface. The nut has a first side facing the disks and a second side facing away from the disks. The nut is disposed to axially compress the disks together on the disk gang bolt when tightened. A tensioning structure is mounted on the disk gang bolt outside of the nut. The tensioning structure has a plurality of threaded through holes. A plurality of threaded fasteners are threadably engaged with the threaded through holes and are disposed to axially compress the disks when the plurality of threaded fasteners are tightened, thereby permitting the nut to be further tightened.
