Using EH External Raise and Lower Switches-If Equipped

causym CAUTION: Avoid possible injury or death from tractor movement. Put transmission in PARK before using external raise and lower switches. Stay clear of rotating drivelines and interference points.

NOTE: When using the fender mounted switches, the rockshaft raises and lowers at a slower rate, and the height and depth settings are ignored. Fender switches are disabled when hitch is in transport position.

Press and hold switch to move rockshaft:

  • RAISE implement with top switch.
  • LOWER implement with bottom switch.

Once either switch is activated, the rockshaft is prevented from moving accidentally. To reactivate the rockshaft, return to the operator station:

  • Move hitch control lever (A) to position that corresponds to position of the draft links.
  • Actuate raise/lower switch (B).
Adjusting Raise Height

Control the implement height with knob (C):

  • For minimum height, turn COUNTERCLOCKWISE.
  • For maximum height, turn CLOCKWISE.
Adjusting Rate-of Drop

causym CAUTION: Excessive drop speed may cause personal injury or damage to tractor and implement.

Fully lowering implement should take at least 2 seconds.

Control the speed the rockshaft and mounted implement lowers with knob (D):
