Part of the Case IH Repair Manuals.
All 536 pages of this Case IH Precision Hoe 800 Air Hoe Drill Service Manual (OEM #84425024) zero in on one machine: the Precision Air Hoe Drill, from primary hydraulic circuits down to the air seeding system. Inside you get hydraulic schematics for the full primary power system, wiring diagrams for lighting and electronics, fault codes with diagnostics, and a torque section covering tubes, fittings, and every critical fastener. You'll also find frame folding and levelling procedures, front axle service, and all three seeding systems (mechanical, electronic, and air) in the Field Processing section. Torque the opener head bracket V-bolts to 122.0 N·m (90 lb ft) and run caster tires at 410 kPa (60 psi); both numbers come straight from factory spec. Your drill is down and every idle hour costs money. Grab the PDF, pull it up on your tablet, search by section bookmark, and start wrenching.
