Now I'm no expert, but...
To the uninitiated, the practice of securing the blade of a frost fan by tying it down so hard it bends seems like a bad idea.
What sort of stresses are being induced on the blade and the gear?
Now I would presume that there ARE enormous stresses caused by the normall running of the machine, but this would appear to be an unatural one and non-symetric to boot.
For those who are interested the location is here.

Perhaps OSH and Orchard-Rite (In New Zealand that would be Williams and Kettle) would like to have a chat with the local agents? (That would be Marlborough Tractor Services (03) 572 8787))
