Nothing other than getting in way when you need to hook things up. It is supposed to pivot up with a spring return during mount and dismount of implement pto shaft.
To the op, best is to look at stud spacing in the rear of diffy and above the pro shaft and taking some measurement to fab up out of 18 gauge sheet metal, nothing difficult. Don't have the dimension and have not seen many 1700 with it.
