When a Rex starts flashing alarm codes on the check-control display or the shuttle slips in the middle of hay cutting, this 491-page Landini 90F service training PDF (OEM ID 3665258 M1) is the factory course for it, covering six Rex variants from the 70GT up to the 100GT. Wiring diagrams trace the electrical system through the biggest chapter in the book, and hydraulic schematics map the low pressure circuit before showing you how to inspect operating pressure values. Transmission disassembly and adjustment guidelines follow, then alarm code tables, calibration procedures and drawings for making the special tools yourself. Fit filtration at 60 micron on the intake side and 20 micron on the delivery, and hold critical assemblies within plus or minus 5 percent of specified torque. Out at the far shed, it's you and the tractor. Bookmarks and a searchable text layer drop you on the right chapter in seconds, while the weather holds.
