  • Question on BN-040 Moto-Tug Brakes
  • The Massey Air Museum (Eastern Shore Maryland) is restoring a Ford-Ferguson Moto-Tug BNO-40 #2269 and we have discovered that it had what I can only describe as Disc Brakes although not the caliper and disc we’re used to seeing on cars (or on planes for that matter) - more like a clutch with a pressure plate (backing plate) that squeezes the disc brake pad against the drum. Does anyone know what these brakes are? Who manufactured them? What were they used on? One side locks up (and releases) and we’re trying to diagnose the problem.

    You can see all the photos from the Link to the whole album below.

  • FORD TRACTORS were notorious for having poor brakes. When the Moto-Tug was designed by FORD engineers, they went to a hydraulic braking system. The Moto-Tug was first used on US Carriers during WWII to move Vought airplanes around the deck on. On a Carrier, at best the only barrier to prevent going overboard was a rope or chain if at all even that. Relying on the standard 9N braking system was not advised thus the hydraulic setup with a mechanical hand brake lever as a backup was developed. Here is the LINK to our HISTORY Forum with my article on the Moto-Tug.

  • I have no information for you about a BNO-40, BUT WOW, oh WOW! I have been looking for some fresh pictures of B-24 #139. I bought a book at the Yankee Air Museum about #139 but, I can't find it right now. I don't believe it has these pictures.
    The address: "American Legion at 2094 E. Michigan Avenue, Ypsilanti" is on the south side of E. Michigan Ave. The plane eventually was parked on the NW corner of E. Michigan Ave. and Spencer Lane (now occupied by E.B. Brown). On the NE corner stands a building that was a grade school during the war and where I went to kindergarten 1948-49 and part of my 1st grade, 1949 to March 1950. It is now a church.
    One block east of Spencer Lane is Emerson Street, where I lived at 233. As the crow flies, that is about a mile from where the Ford, Willow Run Bomber plane was located (now gone).
    The only security around the plane was a snow fence. Older kids had knocked it down and as a 5 and 6 year old kid, I got to climb into #139.
    In March of 1950, we moved about 7 miles south (as the crow flies) to a small farm. I don't remember seeing that plane again after we moved.
    It was later sold for scrap, cut up and hauled away.

  • One side locks up and releases.
    I suspect, if you take apart the cylinder and look down the length of the bore, you might see an ocean wave instead of a flat surface.
    That's just my 2 cents.
