Installing a 3rd function hydraulic kit on a Case IH D40 tractor - Part 4 - 047

This is part 4 of an owner's DIY third-function hydraulic kit install on a Case IH D40, covering the final hard-piping into the diverter valve's power beyond port, wiring the joystick control switch, and the first grapple test picking up a log. It includes real frustration points: no dealer schematic support, wrong initial hookup, and why hard pipe beat hoses in tight spaces. Best for owners mid-install on the same tractor.
