JD111H and JD160

I offered to help an acquaintance get his two John Deere tractor running.  I was expecting tractors from the late 90s or newer but ended up looking at a JD111H and a JD160.

So far all I have done is attempt to air up the tires.   Tractors with flat tires are had to move.  One of the rears on the 160 has a tube but should have gotten a boot to go with it.  The other 7 took air do not know how long they will stay up.  Lot of cracking sounds when I filled them.
