4 X 4 Project

[KENPOND]

Hello ALL,
Living I southern Maine I am always looking for winter projects. I am the original owner of a 1970 Case 444 and just bought a 1982 Case 448.
The next project is a Hydraulic drive 4 x 4 .

What I am looking for are (2) Case Hydraulic Drive rear axles with hydraulic motors for this project.
Any one have a good idea as to what would be best the 444,448, or any of the newer Ingersolls. That by the way they are made here in Portland, Maine by Eastman Industies.

Thanks for any help
Ken
