many times, the links going down to the lower lift arms. 1 link will just be a solid metal piece, while the other one being adjustable, examlle a turn buckle.
you can replace the solid metal piece with another turn buckle. and/or swap the 2 links around if that is what works out.
you can also replace the lower lift links with longer ones.
NOTE: telescopic lower lift arms. are generally only designed to pull out to initially hook up to equipment. and then you reverse tractor into equipment to lock the lower lift arms. with that said, there might be a couple telescopic lift arms that allow you to adjust and pin the lower lift arms at a certain length.
pats easy hitch can be rather nice. just simply hooking up to 3pt hitch equipment.
to note it... what ever you end up doing for the plow. may result in dealing with needing a new PTO shaft for the rotatory mower (bush hog) if you do not want to remove a bunch of stuff (long lower lift arms, pats easy hitch, or some other quick attach on 3pt hitch) and put the old stuff back on just for the rotatory mower. to note it, they do make a PTO shaft extension. might be cheaper on wallet vs new pto shaft if that is even needed.
darn if you do, darn if you do not.
=================
longer lift arms, may result in needing new sway bars/chains (bars on side of the lower lift arms)
along with i would suggest getting some check chains installed as well.
the swap bar/chain and check chains help protect the 3pt hitch and your rear wheels. and keep the implement out of your rear wheels, at same help keep the lower lift arms from hopefully not buckling and bending when you go into a slight turn and/or backing up with implement when it is on the ground.
lots of little things, but add up into the grand scheme of things
