Hi we had same problem with our 684. Solution was to shorten the left lift link. The yoke part of the lift link screws into a nut on the lower lift link. By removing one end of the lift link and turning it in proper direction the lift link will be shortened. Be Careful not to shorten it to much or the upper lift link will protrude thru the bottom and bind on the 3pt arm when lowered all the way. The right lift arm can then be adjusted with levelling crank. Again be careful that the threaded part of lift arm dose not contact 3pt lift arm. We actually shortened the lift arm by cutting 3/4" off the bottom on both sides. Downside is the 3pt hitch will not lower to the ground as much but this is not a problem for most implements.
