justments appropriate for backlapping (see Bedknife to
Reel Parallel Adjustment).
6. Start engine and move Raise / Lower – Mow control
forward to start the reels.
7. Rotate flow control valve knob to position 1.

(see Special Tools).

cause contact with the reel or other moving

backlapping, turn reels OFF by moving the RAISE/
LOWER–MOW control to the RAISE position. Shut off
engine. After the adjustments have been completed, re-
peat steps 4 through 6.
