About a year ago scanning my local craigslist, I found a newer Toro / Wheel horse 36" roto tiller for $50. Mounted up to my 74, C-160 after I had to trim off a bit of the rear axle mount locking bracket (it's length was bumping into idler pulley). Now I needed the mid mount belt setup, I have a well equipped shop at home so all I needed was some measurements. Built my drive setup close to member "Lost Pup" and his post here
The mostly finished bracket, waiting for 141 x 1/2" belt to arrive, bought off greed-bay. Will tack the set-screw shaft locks in place after belt fitted.
Pic from underside, spring is probably from an old bed mattress. It was just in my junk pile and looks close to being correct size.

Tiller mounting shot, the electric lift is getting weak, has to work pretty hard to lift roto tiller. Plans are to remove and sell it off then replace with my own linear actuator setup.
