Wallenstein BX52S Wood Chipper assembly

[PETDOC]

I uncrated and assembled a Wallenstein BX52S Wood Chipper for my Kubota. Everything is done, but I have 3-10mm x 45mm bolts with nuts in the plastic bag that contained other nuts and bolts used in assembly. I have looked at every square inch of the chipper and can not find anywhere these could be used. Does anyone have any ideas as to whether these go with this chipper or if they were included because the same bag of nuts and bolts goes with other Wallenstein models of chippers?

Are they shear bolts? Extra blade bolts?

You got it, shear bolts for PTO drive shaft. Thanks.
