I'll ditto that from family experience.
My father had an HD-73 turning a Cushcraft A4 and an 11 el Hygain 2m 
beam 5 ft above the A4. If you believe the HD-73 specs this load 
shouldn't have been a problem as both beams and mast were about 65% of 
the rated rotator windload.

The rotator lasted about 2 years.
