Part of the New Holland Repair Manuals.
This BW28 and BW38 bale wagon repair manual gives the Stack Command electronics a full chapter. It covers ECU connections, stack patterns, machine interlocks, input and output tests and proximity sensor checks.
From there it widens out across seven books, part number 87693295, first printed in 2007. It covers the engine, fuel, cooling, the Allison automatic transmission, axles, TRW steering gear, Hydro-max brakes and cab A/C. The crop end gets the same depth: bale loader, cross-conveyor, both tables, tie spikes, load rack, rolling rack and push-off.
