by removing the hitch pins from the deck height
pins and lifting the carrier frame off the deck
housing.
3. Drill out the eight (8) pilot mount holes on the
deck housing to 1/4” and deburr the holes.
NOTE: For DC48 decks, there are only four (4)
front mount holes to drill out. The rear mount

Links (#19) or round Rear Lift Links (#20). The
heads of the bolts that secure the Lift Links to
the Lift Saddle need to face out. Install the Lift
Saddles on the housing using eight (8) 1/4-20 x
1/2 button head bolts (F717) and 1/4-20 ange
