IH 1566 working 

Looks and sounds beautiful I would have no problem listening to that all day

What a beautiful machine and sound , We had a 1066 all great tractors !

Great tractor. We had 2 back in 1975. Never forget it.

I have a 706 for my workhorse,, rebuilt slightly,, and new paint,, looks and sounds great

Sharp looking tractor - great engine note too.

Beautiful machine.

Would say the look of the 66 and 86 ih is my favorite about the ih but it's the way they just wind out so high in the rpm

Perfect sound

Great
