An agricultural baler including a sealing assembly positioned adjacent to a baling chamber. The sealing assembly is configured to receive a strap and to seal the strap into a loop around compressible material within the baling chamber to form a strapped bale. The agricultural baler also includes a strap gripper positioned adjacent to the sealing assembly. In some embodiments, the strap gripper includes a pivot plate, a guide wheel rotatably coupled to the pivot plate, and a drive wheel. The pivot plate is biased to rotate about an axis in a first direction to urge the guide wheel toward the drive wheel, and the drive wheel and the guide wheel are configured to receive the strap after the strap is looped around the compressible material, to block movement of the strap away from the sealing assembly, and to drive the strap toward the sealing assembly.
