Yes it will fit MF - any new attachment will - blower, chainsaw, hedger, etc. However, don't know how well the engine would power them - the ryan having the different torque characteristics to the newer 25.4cc screamers
I love the Ryan engines - I think I have about 10 of them
I loose track of the names - lawn hornet, grass scorpion, grass wasp, etc but from memory - 2x 1984-5 RGH600 Grass Hornets with clutch, 1989 Green clutched (issue with reed valve), 1990 grey clutchless, 1991 clutched, 1991 Stihl fs36 (same engine but is being a P.I.T.A), 1998 MTD clutchless LT31CS, early 2000's Bolens straight shaft bull handle brushcutter, and a similar Yard Machines brushcutter with AST spring start
Plenty of toque down low and easy to start - only 3 or 4 goes most times - except for the AST one which can be annoying
I got this email from Ryobi when I inquired a year ago - just wanted to see if they had any of the old manuals etc - I suppose we should call them MTD Ryan Engines
