Check and Adjust Net Pan Pressure

E83228-UN-23MAY17

A - Net Pan Angle

B - Outside Belts

C - Channels

Belts must be tight before checking and adjusting net pan pressure.

Always adjust belt tracking at No. 9 roll (lower front gate roll) by adjusting No. 8 roll (lower rear gate roll) before checking or adjusting net pan pressure.

Lack of sufficient net pan angle (A) and channel (C) pressure can cause the net to wrap the rubber roll or only be partially applied to the bale. The net pan angle (A) must contact both outside belts (B) and at least two of the four center belts.

Excessive net pan angle (A) or channel (C) pressure can cause net feeding difficulties, holes worn in the pan angle or channels, or the net slitting if heating weakens the net.

1. Park the tractor and baler on a level surface. Shut off the engine and remove ignition key.

2. Remove crop debris from inside the gate, near the No. 8 and No. 9 rolls and the net pan.

3. Start the tractor engine. With the baler empty, gate unlocked and closed, engage the PTO and move the tractor SCV lever to close the gate and tension the belts.

4. Disengage the PTO, shut off the tractor engine, and remove key.

   A - Net Pan Angle

   B - Clearance

   C - Outside Belts

   D - Cross-tube

   Check that net pan angle (A) is contacting both outside belts (C) and at least two of the four center belts.
   • If the net pan is contacting both outside belts and at least two of the four center belts, proceed to the next step.
   • If clearance (B) exists between the net pan angle (A) and any belt, adjust the cross-tube (D) higher until both outside belts and at least two of the four center belts contact the net pan angle. Maintain 22—44 N (5—10 lb) net pan pressure on both sides.
   • If net pan pressure is 22—44 N (5—10 lb) and either one or both outside belts (C) do not contact the net pan angle (A), the net pan angle is bowed too much and must be straightened. (See Check and Straighten Net Pan Angle in this section.)

   With a spring scale, engage scale hook (A) at bend (B) in the net pan angle (C).

7. Force must be 22—44 N (5—10 lb) to move the net pan away from the outside belts.

   • If force is less than 22 N (5 lb), move the left-hand side of cross-tube (D) up until the force is correct. Repeat on the opposite side.
   • If force is more than 44 N (10 lb), move the left-hand side of cross-tube (D) down until the force is correct. Repeat on the opposite side.
   • If the cross-tube (D) is in the lowest position and force is more than 44 N (10 lb), adjust net pan pressure. (See Check and Adjust Net Pan Pressure in this section.)
