[TowerTalk] TOWER ROTOR

[RICHARD BOYD]

Hector, we admire your resourcefulness!

I had recent experience working on a "Bush Hog" rotary mower that many of us 
are familiar with, that are widely used and widely available.  The typical 
one attaches on a "three-point hitch" and "PTO" (power take off) of a small 
to medium farm tractor.  They are about the width of the tractor, sometimes 
wider and typically have a single large blade.  Particularly the "Bush Hog" 
brand is well made and capable of mowing even saplings (trees of up to an 
inch or two diameter), in addition to just grass and weeds.  This is the 
mower of choice when brush and grass have gotten to be tall -- several feet 
high.  I've mowed brush as much as eight feet high with them.

Getting to the point, there is a gearbox, transfer case, in them that could 
be salvaged from old ones, could be found at junk yards, etc., that will 
give you a 90 degree turn.  It also strikes me these gears could be adapted 
to (welded) prop pitch rotators, etc. for that application as well.  If you 
can find one of these it could give you the 90 degree turn you want.  (It 
seems to me that finding a different way to mount the motor would accomplish 
the same thing but keeping the motor in the orientation you prefer and 
making the turn with a gear assembly may indeed be the easiest and best 
way.)

I am going to start "keeping my eyes open" for old "Bush Hog" mowers with 
the idea of salvaging the gear box.

GUYS:

I WILL LIKE TO KNOW WHAT TYPE OF TRANSMITION AND MOTOR ARE THE BEST TO USE 
TO ROTATE A TOWER, I HAVE A  FEW PHOTOS OF HOMEBREW ROTORS AND OTHER 
COMMERCIAL OUT OF MY BUDGET.  I WILL LIKE TO BUILD THIS  AT LOW COST BUT 
HIGH QUALITY , FOR THAT REASON I WILL TAKE MY TIME AND LOOK FOR THE RIGHT 
PARTS.
I FOUND HERE IN A LOCAL JUNK YARD  SEVERAL TRANSMITIONS WITH MOTOR IN VERY 
GOOD CONDITIONS AND GOOD PRICE 100-150 DLLS COMPLETE , THIS ONES COMES IN A 
MACHINE  THAT WAS USED IN  SOME AGRICULTURAL PROCESS.  VERY STRONG AND  THE 
SHAFT IS AROUND 1 1/8 INCH  , THE ONLY PROBLEM IS  THIS IS MOUNTED 
HORIZONTAL.  IN THE LEFT THE MOTOR AND THE RIGHT THE LOW SPEED SHAFT , NOT 
ABOVE LIKE THE ONE THAT APPEARS IN THE NCJ  THAT HAVE IN USE  A CONTEST 
STATION IN OH0 LAND.

I WILL APRECIATE  IDEAS AND  YOUR OPPINIONS.

TNX IN ADVANCE
HECTOR XE2K
