Thier sure seems to be alot of hate towards international 86 series on the Web! And some towards the 66 series! But my grandpa dad and I have farmed with 66 series and 86 series since 1971 when grandpa but another dislike tractor by many the 1066 hydro which to this day still works everyday on the mixer and yes the engine and tranny have been opened up but 44 years and 20k plus hours can't complain! And grandpa's 1977 1486 which done all the heavy work from 77 till 2000 when I got my 1066 the 14 has had the engine rebuilt and a new reverse gear and a ta buts over 15000 hours so can't complain! My 1066 did get a new differential and ta but I will admit my teenage years and early 20s I wasn't easy on it! And my 966 still goin Strong with 8000 hours and supposedly never been opened up! So for all the ones who say thier nothing but problems I disagree! Yea the 86 series isn't the operator friendly if you compare it to today's tractors! But in 76 I think they were a good tractor and still are!
