that attach the top of the hood to the rear hood. Then
loosen the four bolts (two on each side) that attach
the hood to the left and right frame plates. Lift the
hood up, off the mower.

4. Place the wooden blocks beneath the mower so
that both wheels are raised off the ground.
5. Use the two y 2 -inch wrenches to remove the nut
and boit that secures the large sprocket to the wheel
shaft. (If the bolt seems to be stuck in place, use the
large straight punch and hammer to gently drive the
bolt out of the hole—remember, don’t hammer the
threaded part of the bolt.)
