Manual for tractor mounted snowblower 24574 ?

Hey hey

I have been looking for a manual for my tractor mounted snowblower.
It is a murray tractor and the blower was purchased with it new. (but not by me)
It is model # 24574 and I believe it is compatible with many other lawn or garden tractors.

I checked at murray.com and managemyhome.com and several other searches but nothing.

Anybody got one of these or have more info as far as compatiblity ?
I am thinking of selling want to make sure it will work on something else.

Here is a pic for all it is worth
