Usually, I have been fortunate to have one of my sons to hook up the RC. Last week, I was doing this myself and fould that an extra set of hands would have been nice. I couldn't seem to align the splines, retract the lock collar and push the coupler onto the PTO shaft simultaneously. After much frustration, I separated the telescoping cutter shafts and attached locking coupler to the tractor. I placed a length of 2" PVC across the lift arms to rest the shaft on and adjusted height until telescoping driveshafts were lined up, then backed up tractor and hooked up successfully. Any tricks out there for this scenario. Seemed to take much longer than expected!!
