That is so the 'tower' can act as a 40m radiator.  The 'stinger' does  
not radiate on 40m.

If you wish to use the antenna on 60m, you will need to find a way to  
make the tower + additional 'stub' resonate on 60m without disrupting  
the 40m resonance.

Use the K7LXC directive:  DO WHAT THE MANUFACTURER SAYS.

One cubic yard of concrete holds up the tower against tilting forces  
in strong winds.  It's a MINIMUM amount of concrete.

Good luck
