[TowerTalk] Manually crank down a motorized tower

[Don]

Interesting, curious what the heck you are cranking. I have a 70 foot 
HG-70D and its about 500 turns up or down with the K2550. Good exercise 
and I do it 100 at a time, pull weeds from the flower beds for a few 
minutes or have a frosty 807, then continue and then go on to the next 
external job my wife has for a short period. I have the motor control 
that came with the tower and it sits new in the boxes. Not worth the 
bother to install considering how often I take the tower up or down, 
which is usually only once a year for some brief maintenance. Takes a 
few turns to lay it over or raise it too as I use a double pulley 
system. I also have a Tri-Ex WT-51 and it also has a low crank number as 
I recall.

1000 up and another 10000 down though might make me rethink the latter.
