A cracked disc, a worn roller bearing or a snapped shear bolt on your disc mower conditioner starts with the same job: finding the right part number. This 86-page Gehl 2412 and DC2412 parts catalog PDF (Form No. 908152) is where that number lives. Exploded views break the cutterbar, discs, roll tension system, trailer, hydraulics and electrical down callout by callout, while the universal drive and gearbox breakdowns fill much of the back half. Serial splits are marked plainly, with the roller drive changing at SN11500 and the trailer assembly at SN10500, so you match the drawing to your machine before ordering. Measure the roll tension spring against its 67.00-inch overall length, and order the driveline clutch by its 12000 in-lb rating as part 157429. Hay keeps growing while the mower sits in the shed. Bookmarked, text-searchable and indexed by name and part number, this copy is yours to keep for as long as the 2412 runs.
