Part of the Case IH Repair Manuals.
The monitor throws a row blocked warning, the vacuum fans sound lazy and rain is forecast by the weekend. This Case IH factory service manual covers the Early Riser 1240 Pivot-Transport planter in 12 Row, 16 Row, 24 Row 20, 12/23 split row and 16/31 split row builds.
It explains the electro-hydraulic system on tractor-remote and PTO pump setups. It covers the lift and pivot, marker, coulter bar, multivalve, bulk fill and liquid fertilizer valve blocks, plus PTO pump and gearbox overhaul. Pneumatic down pressure, the AccuRow air clutch, vacuum metering and the Rate, Frame and clutch control ECUs are all included, with wiring schematics and fault procedures.
Guessing costs money. You end up buying a cartridge you didn't need, tearing down a seed meter twice or replacing a compressor when the fuse was blown. Test it once, fix it and get back in the field while the ground is fit.
