Net Wrap Difficulties

Net wrap material wrapped around rubber feed roll.

IMPORTANT: Do not cut net wrap material from rubber feed roll. Any knife cuts in the rubber roll covering may result in more frequent wrapping around the roll and may require roll replacement. (See CORRECTING NET WRAP FEEDING PROBLEMS in Service-Net Wrap section.)

Brake on net feed roll not tight enough.

Adjust brake (See CHECKING AND ADJUSTING NET WRAP FEED ROLL BRAKE in Service-Net Wrap section.)

Static electricity or dampness causing net wrap material to cling to the roll.

Dust the rubber drive roll and outside of net wrap with baby powder.

Net Wrap clings to rubber roll from weight of net wrap for extended periods of time (overnight or longer).

Unlock and relock brake on V-Belt pulley before each use.

Dirt, crop material, rust, or roughness on pan surface.

Clean and polish upper pan surface with SCOTCH-BRITE ® or ultra fine sandpaper. Polish marks must be parallel to movement of mesh. (Refer to USING NET WRAP AFTER EXTENDED STORAGE in Preparing Baler for Net Wrap section.)

Dust and/or moisture on surface of rubber roll causing net wrap to stick to rolls.

Be sure to tape across cover hinge joint at top of cover is intact. Replace if necessary. (See your John Deere dealer.)

Route and thread net wrap correctly. (See THREADING NET WRAP AND ROUTING THROUGH ROLLS in Preparing Baler for Net Wrap section.)

Lower portion of front wall of net wrap too close to rubber roll.

Bend lower portion of front wall away from roll to give at least 3 mm (0.118 in.) clearance.

Bale Not Wrapped (No Alarm-Stop and Net Wrap Indicators Not Displayed)

Net wrap fed to other areas of the machine:

Locate and remove net wrap material before making the next bale. Otherwise, improper belt tracking and further incorrect feeding may result, if material is not removed promptly and the cause is not corrected.

a) Starter roll wrappage.

Remove all burrs, weld splatters, rough spots, and imperfections on starter roll. Mud or sticky crop residue can cause occasional starter roll wrappage.

Net wrapped on top idler roller

Bale diameter too large-Reduce bale diameter to 72 in. or smaller. (Measure a bale to check actual bale size, ensure it is 72 in. or smaller.)

Check for mud or sticky crop on belts and rolls. Clean if necessary.

Make sure all belt pin ends are pointed toward back side of belt toward rolls, so the net wrap does not catch on bent ends of pins.

Check for cut or damaged belt surface. Trim loose belt edges, repair, or replace. (See REPAIRING BELTS in Service-Baler section.)

b) Baler drive roll wrappage.

Do not damage rubber strips when removing net wrap material.

c) Net splitting.

See "Net wrap is split around bale or stays behind the pickup" in this section.

d) Net wrap caught in rough belt splices (net wrap is not transferred from belts to bale during wrapping cycle).

Make sure splices are smooth.

OUO6059,0000073 -19-02OCT00-6/13

Inspect and repair broken or damaged belt splices.

e) Net wrap bunched behind lower belt guide on gate due to crop buildup.

Remove crop buildup from lower gate area. In some crops, reducing PTO rpm while baling will reduce buildup tendency. Ejecting bale with PTO running will reduce buildup in some conditions. (See BALING SHORT, DRY, SLICK CROPS in Operating the Baler section.)

For extreme crop conditions install Build-Up Reduction Scraper Kit. (See Attachments section.)

f) Bale forming belts sticky from silage buildup.

Diamond pattern on belts must be dry. Bale silage at a lower moisture content.

g) Broken or damaged belt splices.

Repair belt splices.

h) Adjacent belts track toward each other causing belts to "pinch" and pull net wrap around rolls.

Adjust belt tracking or move belt to another location to improve belt tracking. (See ADJUSTING BELT TRACKING in Service-Baler section.)

Remove wrappage on baler rolls.

Actuator or controller disconnected.

Check connections and/or wires.

OUO6059,0000073 -19-02OCT00-7/13

Bale not uniformly wrapped (No Alarm-Stop and net wrap indicators are NOT displayed).

Buildup of crop, etc., behind lower belt guide on gate.

Clean out buildup. In some crops, reducing PTO rpm will reduce buildup tendency. Ejecting bale with PTO running will reduce buildup in some conditions.

Install Build-Up Reduction Scraper Kit. (See Attachments section.)

Insufficient number of wraps.

Make sure the net wrap supply roll has not run out.

Controller should be set to apply a minimum of two wraps. (Refer to OPERATING NET WRAP CONTROL in Operating the Baler section.)

Net wrap building up at rear of pan.

Net wrap pan is not contacting belts at rear of pan. Adjust pan to contact at No. 8 roll.

Belts not tracking properly.

Refer to ADJUSTING BELT TRACKING in Service-Baler section.

Too much tension on net wrap causing holes or tears in net wrap.

Reduce net wrap tension by adding shims between pulley halves. (See ADJUSTING NET WRAP TENSION- Section 70)

Net wrap cover not closed.

Cover must be closed and latched for best bale coverage.

Net wrap cover gas spring(s) weak.

Check springs on both sides of net wrap cover. Replace if necessary.

Windguard angle damaged or missing on MEGA-WIDE pickup frame

Install angle-See your John Deere Dealer.

Net wrap not routed between steel and rubber roll .

See THREADING NET WRAP AND ROUTING THROUGH ROLLS in Preparing Baler for Net Wrap section.

OUO6059,0000073 -19-02OCT00-8/13

Roll of net wrap material too narrow.

See your John Deere dealer. Use only approved material for best results.

Net wrap partially on bale, partially on feed roll or baler roll.

See "Bale not wrapped (cutoff signal does activate)" in this section.

Bale has crop between layers of net wrap on the bale or loose crop is outside the net wrap on the bale.

Stop forward travel immediately when the full bale alarm stops. Net wrap begins to feed at that time, and any crop picked up after this will be placed between the layers of net wrap or outside the wrapping.

Adjust monitor to delay starting wrap on CH. 26

Net cutoff light stays on after net wrap has cut off.

Binding at microswitch arm.

Check for free movement.

Too many wraps applied.

Normally no more than three wraps are needed. Excess wraps may appear to be loose.

Varying number of wraps from one bale to the next.

Varying PTO speed while wrapping from one bale to the next.

Maintain rated PTO speed while wrapping. If difficult crop conditions require varying PTO speed while baling, return to rated speed for wrapping.

Bale size and shape not uniform.

Make bales uniform in shape. Follow operating instructions in Operating the Baler section.

NOTE: If wrapping a smaller bale with override switches, the small bale will have a higher number of wraps unless controller is readjusted.

Too much clearance between net wrap guide and CoverEdge drive roll.

Check belt gap. (see CHECKING and ADJUSTING LOWER NET WRAP GUIDE in service Net Wrap.)

OUO6059,0000073 -19-02OCT00-10/13

Net wrap is split around bale or stays behind the pickup.

Belt tracking incorrect.

Be sure right-hand or left-hand end belts do not continuously contact guide washers. On pan, belts should be centered between washers.

Not enough tension on net wrap.

Check tension. If needed, increase tension by removing approximately two shims from between pulley halves. (See ADJUST NET WRAP STRETCH in Service-Net Wrap section.)
