Part of the Case IH Repair Manuals.
All 985 pages of this Case IH Early Riser 1225 Service Manual (OEM #47682582) focus on one machine: the rigid trailing planter that puts seed in the ground when everything else has to be right. Inside, you get a full hydraulic section covering the main control valve, frame lift circuit, vacuum, metering, and marking hydraulics — plus wiring schematics, connector pinouts, and harness diagrams spanning the seeding control and precision farming systems. A deep fault code and troubleshooting section walks you through electrical diagnosis the way the factory intended. Row unit work? Torque your parallel linkage pivot bolts to 79–98 Nm, replace any opener disk worn below 343 mm OD, and set total deflection before it hits 3.2 mm. Your planter is sitting idle while someone's guessing at specs. Pull up this bookmarked PDF on your tablet, search any procedure by keyword, and get back in the field.
