Automatic Header Height Control — Rigid Mode

Operating a flex platform in rigid mode may be desired for some crops and conditions. A combination of hydraulic adjustments and mechanical components will allow a flex platform to be operated in rigid mode.

NOTE: Rigid mode sensor arms MUST be in down position and calibrated each time they are used.

1. Set HydraFlex pressure to maximum, >2700 psi (186 bar).

   F - Cap Screws and Lock Nuts

   Auxiliary sensor arms (A) are located under platform, attached to a float arm (B).

   To release sensor arms:

   1. Remove quick-lock pin (C) and allow arm to lower.

      NOTE: Quick-lock pins must be removed for off the ground cutting.

   2. Install pin at storage location (D).

      IMPORTANT: Avoid header height malfunction and equipment damage. When sensor arms are unlocked (in use), quick-lock pin MUST be stored on float arm (D). Do NOT store pin on sensor arm (E).

      NOTE: To achieve higher cut heights it may be necessary to remove hardware (F), adjust sensor arm reach, and reinstall hardware.

4. To store sensor arms:

   1. Remove quick-lock pin from storage location (D).

   2. Completely lift sensor arm and install pin to lock arm in raised position (E).
