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.

  Bob,

I have a 72 foot tri-ex tower .  Have never user the motor control for it.
I have cranked it up and down manually many times.  You are correct it takes
a lot of cranking.  Once I counted the turns.  It took about 1000 revs to
lower each section ( also 1000/sect. back up  UGHHH).

Good luck,

I have a US Tower HDX589MDPL with the motorized drum.  I was wondering what
I would do in the event that something failed in the control box and I
needed to crank it down.
The gearbox has a worm gear and I believe I could temporarily take off the
chain and turn the gear box sprocket by hand.  I would have to turn it until
the cows come home but I think I could crank it down.  Am I correct about
this ?  Have any of you had to crank down your motorized tower by hand ?
