[AT] Brush hog PTO shaft slop

[drgerber at bright.net]

Mike:  my 513 has been doing the same thing; if I put it on the 630 or 530 it shears the bolt every time; if I put it on the MT or 420 they hold up much longer.

Another question for the list. I have an old John Deere 513 brush hog. 
Lately, I've been shearing a lot of bolts, and I believe it has to do with an elongated hole in both the PTO shaft hole, and possibly the gearbox output shaft. Can you guys think of any remedy to this? Maybe a way to install a bushing, or just drill it out. I've attached a picture, hopefully it comes through.

Thanks,
Mike M
