Get the model & serial number of the tractor. Get the make & numbers off of the current filter.
New Holland dealer is the OEM.
A Case dealer might be able to order them, tho they are the other 1/2 of the big company & normally would not????
(Ford sold out to New Holland, which then ended up with the same international parent co as Case, which is the merged Case & International Harvestor companies. So all are under the same parent company, but New Holland & Case dealers follow their roots of Bluish or Redish lines.....)
Most good automotive stores that sell napa, Wick, or the like can get you any filter you need. Most of my filters say Napa on them. With the model number of the tractor & the current model number of the filter on now, they will get you what you need.
