Part of the Case Repair Manuals.
All 82 pages of this Case 220 Baler Service Manual (OEM #9-64161) focus on a single setup: the 220 Baler, Wisconsin Model THD Engine, and 220 Bale Launcher. Inside, you get detailed service procedures for the gear box, plunger, feeder arm, pickup unit, and the full tying mechanism, including knotter timing that most operators chase for hours without factory guidance. The lubrication section walks you through every grease point from the engine drive and PTO to the crankcase and gear box, backed by exploded views and bale adjustment procedures for tension, uniformity, and measuring stop. Run your PTO at 540 RPM under load, hold the plunger to 65 strokes per minute, and keep the Wisconsin THD crankcase at 3-1/2 quarts. Baler down mid-season is money out of your pocket. Bookmarked by section so you can jump straight to knotter timing or bale adjustments on any device and get back to baling.
