Part of the Case IH Operator Manuals.
This 108-page Case IH DX21, DX24 Operator Manual (OEM #87300158) walks you through every dashboard indicator, control, and daily check on your Tractors before you ever turn the key. Open it and you get the full safety chapter, wiring diagrams for troubleshooting electrical faults, and hydraulic schematics that show exactly how your lift system routes fluid. A dedicated maintenance interval schedule and fluid capacity chart mean you're not guessing between the engine oil, H.S.T. system, and hydraulic filter service points. Set your hydraulic lift relief valve to 130 bar (1849 PSI) and swap that hydraulic oil filter at the first 50 hours, then every 300 after. No more flipping through a torn-up shop copy for the interval you half-remember. This PDF is bookmarked by section, so you jump straight from cover to the operation chapter, tablet in hand, and get back on the seat.
