Thanks chriscokid
I did not know much about the grader so your info is very helpfull.
I have a couple of Cat pull graders and I really enjoyed reading and seeing Chriscokid's compendium about the pull graders. I have gathered bits of information on these graders from here and there but Chriscokid's is most complete that I have seen. Thank you Chriscokid.
Chriscokid's pull grader link warrants a "sticky"!
