Hopefully the bearings are good and tight. I have seen a piece of twine, or long grass get wrapped around a shaft at the seal, and take it out in short time. Something to keep an eye on, on your tractor too, if you happen to be mowing tall grass. It will at times wrap around the PTO shaft.
For your Ford/New Holland equipment, you can go here:
New Holland - Choose your brand
Place your cursor on Agriculture at top right, then slide down to North America left center bottom. It will turn yellow, then click on it.
On the next page that appears, click on "Parts and Service".
On the next page that appears, scroll down to the second paragraph, and click on "New Holland parts search"
On the next page that appears, type your model number in the white block, then click on search. It will have a menu with selections to the left. Select the proper model, and click on it. It will give an exploded view of what you selected, by component. Diagram with numbers, and corrosponding part numbers.
Pretty simple to use, once you use it a couple of times. You can also copy and paste that part number to Google, or similar search engine, and find the price, of aftermarket parts too.
I usually copy and paste to Messicks ( a sponsor on here) who handles more than several brands I have, to compare dealer price, to aftermarket. And a lot of that depends on the particular part I'm looking for. There are certain items where I prefer OEM parts.
