Hi prd, yes the drive certainly is elegant! The work of a mechanical genius really!
I bought my Anniversary 88 with a broken square driveshaft for $300 5 years ago. I've probably spent double that on it now which includes boring the motor out 20 thou, a new cutter disc and a new drive shaft.
The greatest difficulty I had was getting the shaft in. I'd probably cut a slot in the frame to allow the shaft to drop in.
