I have a Von-Weiss 24" actuator that I THOUGHT about testing as a stage of
a backhoe, but never have (or probably will) get to it. It would take 3 or
4 actuators to do the job right, and I just gave up.

Subject: (ET) Satelite Actuator as lift!
Hi all,
I have recently purchased a Venture 36 vdc 18" satelite actuator arm to use
as an alternate to the E-20's lift motor. The unit came with a mounting
swival clamp assembly that I was able to mount to the front lift arm shaft
with a little modification. I had to notch out a 1/4 inch cut an inch and
a half, down the center of the welded lift arm extension on the front of
the tractor, to allow space for the actuator clamp swivel to clear the
bracket. Works like a charm and holds the actuator arm securely in front
of the tractor. I mounted the end of the actuator which also has a
swiveled hole on the end of it, to my modified plow blade assembly with a
bracket and bolt which slides through the actuator swivel hole. I tested
the actuator by clamping test cables on batteries 36 volt terminals and
wired it to the terminal strip on the actuator motor inputs. The unit goes
in one direction, then by switching the polarity, in the other direction.
I know from recent message threds that the original lift motor utilizes two
coils for its up/down direction and need to figure out how to design a
switch that would reverse polarity for the actuator. Perhaps a double pole
double throw switch with one side wired opposite the other? Anyone have
any ideas on this?
For the mower deck, I probably will have a short chain attached to the end
to allow for the deck to float properly when in use. I plan on designing a
mount bracket for the rear tiller to use this same actuator unit so that I
can simply unbolt it from the front and onto the back when needed. Has
anyone else been successful in using a satelite actuator arm for a lift on
an elec-trak?
Thanks,
Bob
