Thanks for the update. That is very odd, for at that time in the early 1980's (1981 to be exact) is when MTD bought out Cub Cadet from International Harvester. It is right when they started their growth and takeover rampage that has continued to this day, although it is the humble opinion of many, if not most, that MTD in many cases ruins the names and reputations of what used to be great machines. But such is the world of cheapness today....
After some VERY lack-luster lawn and garden tractors MTD made with the Cub Cadet name on them in the mid to late 80's, MTD I believe has come to realize that they have to keep the quality and build level of Cub Cadets above that of their lesser priced machines. Hense the removal of the little MTD grass logo from the Cub Cadet line so CC's will get some distinction from MTD's typical standard of cheapness assocation.
On the positive end, MTD has been extremely supportive to most machines they have built, even still supplying most parts for the old International built Cubs, when the truth to the matter is they have been making Cubs now much longer than International ever did. I still think the Cub Cadet 2500 and 3000's are some of the best GT's out there regardless of price, if MTD can get the quality control levels up a little bit, they would be unbeatable machines. What I have seen though is typical of American industry there, trying to pump out too many machines too fast with not enough personnel to properly inspect them.
Just a little MTD tangent

Have fun with your old MTD/Monkey Ward!
