Prepare for Gearbox Replacement

What happens here

With the donor haybine successfully at the farm, the focus shifts to the gearbox replacement. The creator shows both haybines: his broken New Holland 474 and the recently transported New Holland 492. He highlights that both models share the same gearbox cabinet. He then shows the empty compartment on his original haybine where the gearbox was removed and points out the intact gearbox on the donor haybine, confirming it is ready to be swapped into the broken machine. He also briefly considers if the 492 itself might be usable with some repairs, noting its condition.

Goal: Set up for the gearbox swap between the two haybines.
