Many riding mowers have a mower deck that can be disengaged. This means that you can turn off the blades and still move the mower around. This can be extremely beneficial. You want the mower blades off until you get into the area you want to cut. Otherwise the riding lawn mower can kick up miscellaneous debris and send it airborne. You can also damage the lawn mower blades if they suck up stones and twigs. It is easy to disengage the mower deck on a Craftsman riding mower.
Finish cutting your grass. You'll want your grass completely cut before disengaging the mower deck.
Push the brake in fully and shift the lawn mower into park.
Disengage the mower deck by moving the clutch lever to the "disengaged" position. The blades on the mower deck should stop rotating.
Raise the mower deck to the highest setting by turning the height adjustment knob all the way clockwise. Drive your lawn mower to its storage location and park it.
