The Mighty

Hoyt-Clagwell Model 54/75



Actually, this "butt-buggy" was named after the tractor featured on the old TV show "Green Acres" that starred Eddy Albert and Eva Gabor.  As it is, most folks don't get it.  When folks ask me where I got the tractor, I say, "Hugh Haney sold it to me".  They still don't get it.


The running gear is the remains of a formerly junked Sears Suburban garden tractor from about 1975 and is powered by a circa 1954 Fairbanks-Morse ZC-52 pump engine, hence the "54/75" designation.


The engine started off as a trunk load of rusty parts that a friend was getting ready to throw in the dump so I  guess you can say I cheated the junk man twice with this project!


In low-range low gear, the Hoyt-Clagwell will go at a very slow crawl.  In high range 3rd gear, it will run at about a fast walk.  I use it around the place to pull a utility trailer (sometimes with a half-ton of rock or dirt on it) and it has plenty of pulling power, especially in the lower range.


In order to mount the Fairbanks engine, I first welded two lengths of "I" beam to the frame.   Drive is via Vee belt from the right-hand flywheel rim (as seen sitting on the seat) to a pulley on an added jackshaft.  Inside the frame, a Vee belt pulley is mounted on the jackshaft which carries the belt that runs to the transaxle.


The clutch consists of the alternator from a junked Yanmar commercial mower.  It pivots to allow the belt to loosen when the clutch is depressed.  A secondary use for the alternator (since it actually works!) is to keep a small Gel Cell battery charged so I can blow my AH-OOO-GA horn.  Later on, I added a small 12 Volt siren so now, I can be really annoying.


I've also got an exhaust whistle.  The whistle toots melodiously every time the engine fires when I push the lever.

It's me again, terrorizing the folk at Zolfo Springs, Florida in 2006 (different hat!)

And, yes, I did paint the wheels and running boards white



In response to a numerous request, here's the whistle.  I  got it at a show several years ago and it was so cute I just couldn't pass it up.  The shiny part is what I bought and the dull part is what I made.  It blows using exhaust pressure.  In the black part (the whistle base), there's a poppet valve.  Also, at the top of the muffler is a butterfly valve.  I've got it rigged so when I open the poppet valve, the butterfly closes.  This makes enough pressure to blow the whistle "toot-sweet" as we say in Kaintuck.




Here's a short YouTube video of it at the Boonville Indiana Fall Show in around 1999.


And here's another video, taken in September, 2008.
