How much does it cost to combine corn per acre?

Excuse me, could you please elaborate on the cost associated with combining corn per acre? I'm curious to understand if there are any specific factors that contribute to this cost, such as the type of equipment used, the labor involved, or perhaps the geographical location of the farmland. Additionally, are there any variable costs that can affect the final tally, such as fuel prices or the market value of corn at the time of harvest? Your insights would be greatly appreciated.
