TGReaper.....The blower is a New Holland spec'd for that tractor. The tractor, blower and everything is brand new so nothing is wore out. I only have about 25 hours on the tractor and less on the implements.
LeonZ and Jake98.....The chain tension is set per the spec in the book and the shear bolt is just a regular 5/16 X 1-1/2 grade 5 bolt that you will find in any hardware store. This is the bolt that the specs call for.
I still need to see what chain I have when I get back home, but if this happens again I will be contacting the dealer to see what I am doing wrong or what my options are. At this time I have made sure I have some master links on the tractor.
The other thought is that I will eventually have all the rocks blown out of my path and won't have to worry about it anymore. :laughing:
