Part of the Case IH Repair Manuals.
Packed into 146 pages, this Case IH service manual covers the MD72, MD82, and MD92 disc mowers from initial tractor hookup through complete driveline and cutter bar overhaul. Inside you get a full set of exploded views across every disc module, overrunning clutch, bevel gearbox, and U-joint assembly, plus step-by-step hydraulic cylinder procedures for teardown, inspection, and rebuild. Open the torque section for every fastener spec in the driveline, or flip to the troubleshooting charts when your cutter bar isn't floating right. Knife bolts torque to 159 N·m (117 lb ft), disc hub retaining bolts go to 224 N·m, and the MD72 flotation spring measures 845 mm between coil ends. Your machine is down and cutting season doesn't wait. Bookmarks jump you straight to any procedure; open it on your tablet at the mower and start wrenching.
