Description:
The design is a sub-soil cultivator with sharp edge standards, and shovels designed to present minimal resistance for forward or backward movement. That includes use of bolts recessed in sockets in the shovels, with holes in the bolt heads for a pin spanner wrench. The specifications describe a corresponding wrench-headed clevis pin included as part of the design.
