JD 550 How many links in the track chain?

Post by LewM » Mon Nov 24, 2014 6:23 pm

I just bought a 1980 model JD 550 that need new undercarriage, when I went to order it the salesman looked it up and thought that it called for 37 links but I had counted 36 links. Is there anyway that someone has taken a link out? Does anyone know for sure how many links it is suppose to have?

taking a link out is not uncommon when the chain is worn past the point where the adjusters cant keep it tight enough to keep it on. I will assume that your sprockets are needing replacement as well !
