Abstract
An accessory mounting system a swivel assembly has a swivel member defining first and second swivel member connector portions, a swivel housing, and first and second bearings operatively arranged between the swivel member and the swivel housing. The accessory mounting system operatively connects a helical pile driving system having a rotational drive system and at least one clamp system to an accessory. The first swivel member connector portion is adapted to operatively connect the swivel member to the drive system. The second swivel member connector portion is adapted to operatively connect the swivel member to the accessory. The swivel housing is adapted to engage the at least one clamp system such that the clamp system may be operated to fix a position of the swivel housing relative to the drive system. The first and second bearings are configured to allow rotation of the swivel member relative to the swivel housing.
