Attached is a photo of an aircraft tug a friend built from a walk behind
snow blower with a failed engine. The transmission allows speed control
going forward plus reverse.
Works very well on his RV-6.

Subject: AeroElectric-List: Aircraft Tug
Hello all
I'm looking at building a 12v battery operated aircraft tug, not a ride on
just a walk with. My max aircraft weight will be about 1800 lbs.
I am looking for advise on what size motor I will need. There are a few 12v
motors for sale on ebay but they are not rated in hp so am not sure of what
specs I'm looking at.
One thought was to use a car starter motor but that is not rated for
continuous service but the farthest I will go with the tug is 100 yds and
I'm not sure if it will cope with that distance. A friend has also suggested
converting an alternator into a motor, not sure what that entails. Ebay has
scooter motors with a speed controller that seems ideal but not sure if that
will be powerful enough but it will be geared right down.
I look forward to hearing your thoughts and ideas
Thanks
Mike

Hi Bob,
Regarding the Engine Bus Alternate feed, I was envisioning it being on
during normal flight operations, since pilots are trained to switch
off the Master if they suspect an electrical fire. This would shut
off the alternator too, resulting in the engine stopping unexpectedly.
It is unlikely that the pilot would remember to turn on that switch
before shutting off the Master, especially a second owner.

Hi all,
I'm using an IR alternator as my primary source of electrons on my Velocity. I'd
like to provide overvoltage protection to include a B-Lead disconnect relay.
With a 34A continuous normal system load, will an automotive cube relay rated
at 70A be satisfactory in lieu of the normally used "metal can" style battery
contactor?
Having read tons of posts on the relative merits of internal and external regulation
and pedigree in millions of automotive hours of service, I'm really just
interested in the actual b-lead disconnect relay part of the architecture as
shown in Z-24. :)
Thanks for your help!
Dan

Bill,
The motor is =C2=BD hp 12 VDC. This particular motor was manufactured by L
eeson, Cat. No. 108074.00. Baldor and Marathon offer similar motors.
This tug is used on a grass strip on a farm, and the entrance to the shed w
here the plane is kept is gravel, and slightly uphill. The tug has never h
ad a lack of power or traction.

motors for sale on ebay but they are not rated in hp so am not sure of wha
t specs I=99m looking at.
One thought was to use a car starter motor but that is not rated for contin
uous service but the farthest I will go with the tug is 100 yds and I
=99m not sure if it will cope with that distance. A friend has also suggest
ed converting an alternator into a motor, not sure what that entails. Ebay
has scooter motors with a speed controller that seems ideal but not sure i
f that will be powerful enough but it will be geared right down.
I look forward to hearing your thoughts and ideas
Thanks
Mike

I can't find it now, but several years ago someone up in the snow belt
posted pics of slightly modifying a small stock snow blower. Basically
just unbolted the blower assy & bolted on an adapter to grab the wheel.
He said it was simple to convert back to blower function for use in
winter when he wasn't flying. IIRC, he bought it from his local big box
store for a couple hundred dollars.
