Not Cubs but B's. Thusly the name Honey Bee. Later they used 140's and the like.
They were done in Everly Iowa. IH dealer owned this operation and for years used preowned tractors. Rebuilt them and did his own conversion. Not a conversion for the faint of heart though. The torque tube and one axle housing was shortened along with other adaptations.
Many in this area were used in fertilizer plants.
