Checking and Adjusting Net Wrap V-Belt Idler Tension

causym CAUTION: Protect bystander. To prevent injury, be sure bystanders stand clear before operating net wrap unit or baler.

1. Remove v-belt and idler pulley from left side of unit.

2. Connect monitor-controller power plug to tractor convenience outlet.

3. Turn tractor key to ON position. Do not start tractor engine.

4. Press and hold DEERE key while setting selector switch to NET symbol to turn monitor-controller ON.

5. Continue to hold DEERE key and press PLUS key until "CH 14" appears in digital display.

6. Press RETRACT key to extend actuator fully (angle to highest position).

7. Check position of right-hand net wrap cut-off arm (A). Arm must contact tab (B) FIRMLY. If correct, proceed to Step 8.

If position is not correct, adjust base end of mounting bracket as follows to obtain firm contact:

causym CAUTION: To avoid personal injury from unexpected knife movement, disconnect net wrap actuator wiring connector or power plug when making adjustment or working in area.

b. Loosen two screws (A) on top of bracket, two round-head bolts (B) and nuts on bottom end of bracket.

c. Connect monitor-controller power plug to tractor convenience outlet. Repeat Steps 3-5.

d. Retract actuator fully (to shortest position), and tighten bracket mounting bolts.

e. Extend actuator and recheck for firm contact.

f. Retract actuator fully.

8. Install V-belt, cap screw, and pulley as removed. Torque to specification.

10. If clearance is not within specifications. Adjust idler (A) in idler arm slot until clearance is within specified range.

11. Retract actuator and re-extend to check for correct adjustment. If adjustment is still not correct, re-adjust idler (A) and re-check.

12. Close net wrap cover and shut actuator door.

IMPORTANT: After adjustment, turn monitor-controller ON. Press WRAP key to return net wrap cut-off arm to home position. Turn monitor-controller off to cancel STOP alarm. If this procedure is not followed, net will be fed continuously during the next bale.

13. Connect monitor-controller power plug to tractor convenience outlet. Turn tractor key to ON position. Do not start tractor engine. Set monitor-controller selector switch to NET symbol to turn monitor-controller ON.

14. Cycle actuator several times using WRAP key.

15. Press WRAP key and return net knife to home (downward) position.

16. Set monitor-controller selector switch to OFF (centered) position. Turn tractor key to OFF position. Remove key. Disconnect monitor-controller power plug from tractor convenience outlet.

17. Perform Torque Check

Check roller torque by turning bolt (A) clockwise with torque wrench. Do not tighten bolt (A) more than 40 N·m (35 lb-ft) or damage to bolt may occur.

Specification

Rubber Pad Brake-to-Sheave Brake Roller Torque -Torque 20-40 N·m  (14-34 lb-ft)

18. If torque is less than specification, net cutoff may not function correctly and adjustment shims should be installed.

19. To adjust feed roll brake:

a. Release feed roll brake by pulling out and up on handle (B).

NOTE: If worn, rubber brake pad can be reversed.

b. Loosen nut. Install shims (C) one at a time, between brake pad (D) and bracket until torque is within specifications. Put extra shims behind bracket.

IMPORTANT: After making this adjustment, turn monitor-controller ON. Press WRAP key to return net knife arms to home position. Turn monitor-controller off to cancel STOP alarm. If this procedure is not followed, net will be fed continuously during the next bale.

c. Connect monitor-controller power plug to tractor convenience outlet. Turn tractor key to ON position. Set monitor-controller selector switch to NET symbol to turn monitor-controller ON.

d. Press WRAP key to cycle net wrap actuator. Counterknife at home (downward) position

e. Set monitor-controller selector switch to OFF (centered) position Turn tractor key to OFF position. Remove key. Disconnect monitor-controller power plug from tractor convenience outlet.
