help ID Troy-Bilt tiller please
 

hello,
I bought a rototiller at a local auction and I am hoping someone can tell me
what model this is.

I have a picture at http://www.sdc.org/~brewster/troybilt.jpg

I think the motor may have been replaced, but it is an aluminum block
Tecumseh with no horsepower indication, pull start, and plastic fuel tank
labeled "Unleaded only". The tires are 13" x 5" tractor treads. The tines
measure 12" in diameter and the width of the tine shaft is 13". The tine
guard is 20" wide. There is a forward and reverse gear with high/low speed
slectable by moving the belt (2 fwd, 2 rev. speeds total).
There are no other labels anywhere.

Any help is appriciated!
