I always thought I was hard on equipment,,when I got my JD 650,,
and realized the top link was bent, I decided, I did not know how to abuse equipment.
The top link worked, the attachments I used the tractor with never need top link adjustment,
but, I just could not stand looking at the bend.
It took a month of weekly shopping, I finally found a JD top link from a full size JD tractor.
The body is cast steel, and the rods are 50% larger diameter.
The top link is CAT2/CAT1,, so I had to add a sleeve at one end,,,
I figure the tractor will break in half before I damage that top link!!
