The mount_nfs manpage tells you:

     -2      Use the NFS Version 2 protocol (the default is to try version 3
             first then version 2).  Note that NFS version 2 has a file size
             limit of 2 gigabytes.

Linux used to, and maybe still does, have stability problems with
NFSv3, so the default was/is to use NFSv2.  FreeBSD has no such
problems :)
