Part of the New Holland Repair Manuals.
Hay season stops when your Mower-Conditioner stops. This Ford New Holland 472, 477, 478, 479, 488 Service Manual (OEM #40047253) runs 24 pages and stays on one job: getting the machine cutting again. It walks the full wobble drive and gearbox rebuild sequences, reel shimming and tine bar bearing work, and conditioner roll removal on both the right and left sides. Exploded views show how each component stacks together, and torque tables tell you where to stop the wrench: knife head bolts at 85 ft. lbs. (115 N·m), reel drive chain deflection set to 1/4" (6.3 mm). These are the factory numbers, not forum guesses. Every section is bookmarked, so you can jump to wobble drive, gearbox, or conditioner rolls on a phone in the field or a laptop in the shop.
