When I have asked around about this in the past, this is the only resource that has surfaced:
http://www.nass.usda.gov/Statistics_by_State/Pennsylvania/Publications/Machinery_Custom_Rates/custom10.pdf
 
More based on polling farmers than calculating from actual cost of operation.  And, definitely grain or forage oriented (I have never asked Vern if he has seen something like this for vegetables/fruit?).  But, it still should be useful in giving you a place to start from for your calculations.
    New England Ag Statistic apparantly doesn't do anything like this, but might if asked.  They have often expressed interest in gathering information that farmers in the region might find useful.

Subject: Tractor Cost.

Good Morning Everyone,
I am looking for a cost per hour to run a tractor and implements. Trying to figure out a rent/share with a neighbor. It’s 35hp diesel. Loader,tiller for now.
Thanks
Joe
