Welcome to TBN
To my knowledge, this has never been done by anybody here on TBN-discussed a few times but never done...
You will have to fabricate the front hitch, as well as the front PTO hanger to get it to work...Being able to see in person both setups would probably help immensely, as well as proficiency in navigating through jdparts.com also.

take a look at the front quick-tatch "m01471x" on the jd parts site. there is a chance it could work
the box around the gearing on the thrower should have a 1" dia stud sticking out either side on the upper back corner and a 3/4" hole below to receive pins
you will also need the front pto kit which extends the mid pto up front via a driveshaft and pivot going upfront
lookup jd part number AM124588 it is the frame that is part of a "quick-tatch"
the part # are for ideas only
