what little bit I ran the TD6 last year showed my how sloppy the pins are in the blade. if I raise and lower it on the garage floor the arms travel about 2 inches before the blade starts to lift off the ground. I pulled the main pin to see if I could drill it out and put a bigger pin in today. then I saw a lot of the play comes from that big round circle disc where it attaches to the back of the blade. now how would I tighten that up? seems like sort of a lost cause when I look at the pivot arms and they are real loose too. is it worth fixing or should I just learn to live with it? seems weird that IH put grease fittings on every silly little thing but not on the blade pivot points...
