This is the factory service manual for the McCormick International B-47 pickup baler, publication SM-23, running 146 pages. It is written for the mechanic overhauling or repairing the baler rather than just operating it.
The manual works through the machine system by system: the hitch, driveshafts, and flywheel; the main gearbox, crank, and power train; the plunger and bale chamber; the pickup and auger drives; the axle and cross conveyor; and the full tying and twisting (knotter) mechanism. Each system includes removal, dismantling, inspection, assembly, and installation, along with the adjustments that make a baler tie cleanly.
You also get baler timing procedures, bale length and density control service, torque data, spring specifications, and exploded views to guide reassembly and parts identification.
