Why do you think this is? The shape? The shanks on the field cultivator appear to be a bit longer than the ones on the ROBB. I have a RO720 ROBB.
Five parabolic shanks on Field Cultivator are 1/2" width; area of point 20.3 square inches.
Five angled shanks on ROBB are 5/8" width; area of point 6.6 square inches.
Field Cultivator has easily perceived LESS draft resistance. It has to be the parabolic shape.
bcp's attachment in Post #40 contradicts my experience.
