Are the rivets nessesary on my bolens blades..??

Seems that all they do is break the hub if you hit something hard..

P S.. my wife likes to do that.. :wallbanging:

My lg frame has been doing well without the rivets and I do keep an eye on them loosening up,,and nothing so far..

I just bought a new set of blades for the T F and one of the hubs is buggered up prety good.. I'm thinking of going without the rivets....

Thoughts ????????????????

The rivets provide a positive drive mechanism for the blades. Without the rivets, keeping the blades from spinning loose my require over-torqueing the bolts. Over-torqueing the bolts can deform the blade adaptors to the point the blade comes loose . Once deformed, the blade adaptors won't hold the blades in place, no matter how tight the bolt is. Most every modern blade adaptor has some positive drive mechanism. In the old days, there were hard "fiber" washers placed between the blade and the blade adaptor. This fiber washer helped to distribute the force of the torqued bolt over a bigger area of the adaptor, yet allowed the blade to spin if you "hit something hard". Perhaps you could find some of these fiber washers to use instead of the rivet. McMaster Carr #

90132A552 looks similar to the washers I'm thinking of.
