Slightly different design, but on my 2544:
1) I place a 1"x2"x3ft long pc of wood under the nose roller.
2) Lower the deck as low as it will go.
3) Release the drive belt.
4) Release the left and right lift arm spring loaded J-pins.
5) Lift up on the pc of wood to raise the deck and release the nose bracket.
6) Slide the deck out from the side.
Takes me about 2min. Thing is, my 44" only weighs about 100lbs fully dressed. Your 60" is probably 2-3x that.
