My 709 bobcat hoe is to narrow to clear the outside of the boom on my LS 160 so using the Bobcat upper mount brackets is out of the question. Of course your case may be different.
Do yourself a favour and ditch the Bobcat system for a “quick release” 3rd point link for a tractor 3pt hitch.Seen this setup used on a large Cat skid to a JD 911 pro backhoe and it stood up fine
Its plenty strong to steady the bucket dump cylinders and the hoe. And easily adaptable to several machines with the cost of a pin and sperical ball from you favourite tractor dealer, ie New Holland or Jd
