Bought this tractor couple days ago.According to serial number built late 1976.So one of the last Farmall 666's built before International rebadged it the International 686 to coincide with the new 86 series tractors.This 666 has 3641 hrs. on a working meter.Other than faded paint it is in very good condition and runs and operates very well.I also have a 656 built in 1966 and a 686 built late 1977.Interesting to note the subtle differences between the 666 and 686 tractors I have.Like flasher/turn signal wiring or lack thereof.666 flashers only but 686 flashers plus turn signals.666 has both a oil pressure warning light plus mechanical guage whereas the 686 has just the warning light.This will make a nice addition to my small haying operation. Thank's Paul
