See those blades around quite alot. Fella on epay, jrhaines may have one. I just bought one from him and he also had a JD
, but they mount diff and are lighter. Think blades from 70's to 80's are all interchangeable. There are diff lift links to tractor tho. You won't need that long round one with the spring on one end, you will need the link with two yokes welded on a 3/4" rod, about 2.5 ft long I believe. Just look for the blade that has the two mount rods that hang off those four blocks under your frame. Should be some flat stock to go between those mounts, couple of little locks to hold up the front rod, and little flat stock hangers to go from those rod mounts down to the blade frame. Yahoo group for PK
's has pictures and postings about the blades on the site. Myself, would look for a PK
blade. It fits right and is plenty heavy, better than lots of other brands.
