WING CUTTING UNITS
1.Remove the two Wing Cutting Unit Belts from the steering column.
2.Release the Laches (A) from Wing Cutting Units. To release the latch, lift the wing cutting unit handle until the latch swings upward into a nearly vertical position. Carefully lower the cutting unit to the ground. Avoid dropping the cutting unit, as damage may result to the cutting unit, the mower, or your turf.
3.Slip wing Cutting Unit belts (B) over Countershaft Pulleys (C).
4.Block mower wheels to prevent mower from moving forward. Pull Wing Cutting Units (D) forward so that they slide on Pull Rods (E) and compress springs (F). This will allow enough slack to enable belts to be installed over Reel Pulleys (G).
5.Pull Cutting Units backwards to adjust belt tension. Tighten bolt (H) to lock in place.
