Net Wrap Difficulties

Symptom Problem Solution

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 torque too low.

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

Lower portion of front sheet is too far away or too close to rubber roll.

Bend lower portion of front sheet to obtain 3-6 mm (0.12-0.24 in.) clearance between front sheet and rubber roll. (See CHECKING FRONT SHEET TO RUBBER ROLL CLEARANCE in Service-Net Wrap section.) (See your John Deere dealer.)

Net looped away from steel roll and contacting counterknife angle.

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

Counterknife angle is not raising high enough.

Check idler. (See CHECKING AND ADJUSTING V-BELT IDLER TENSION 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. (non-corn starch)

Symptom Problem Solution

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.)

Hole wear in surface wrap side panel causes reduction in brake torque.

Check for hole wear in side panel. (See CHECKING HOLE WEAR IN SURFACE WRAP SIDE PANEL in Service-Net Wrap section.)

Weld key stock to side panel. (See your John Deere dealer.)

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

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

Clean rolls. (See USING NET WRAP AFTER EXTENDED STORAGE in Preparing Baler for Net Wrap section.)

Dry off rolls if dew is present. Thread net wrap.

Contact between v-belt idler sheave bolt head and pan bolt head or strap may not allow counterknife angle to contact knife.

Check for contact between bolt heads. (See CHECKING FOR LEFT-HAND SIDE COUNTERKNIFE CONTACT in Service-Net Wrap section.)

SCOTCH-BRITE is a trademark of the 3M Company.

PP98408,0000169 -19-14OCT09-5/18


Symptom Problem Solution

Net wrap wrapped around No. 8 roll spirals

Too much clearance between knife and counterknife angle, especially in middle. Center area cut is delayed and creates outside tails that may wrap spirals.

Adjust knife-to-counterknife angle clearance. (See ADJUSTING NET WRAP COUNTERKNIFE in Service-Net Wrap section.)

Crop and dirt buildup at top of brush prevents counterknife angle from contacting knife.

Remove, clean, and install brush. (See INSTALL and ADJUST NET WRAP BRUSH in this section.)

Nicks and burrs on spirals.

Remove burrs with a hand file.

Tighten left-hand side #8 roll support hardware.

Avoid making oversize bales that deflect left-hand side #8 roll into frame.

PP98408,0000169 -19-14OCT09-8/18


Symptom Problem Solution

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.

b) Net wrapped on top idler roller

Bale diameter too large - Reduce baler diameter to 60 in. or smaller. (Measure a bale to check actual bale size, ensure its 60 in. or less.)

Avoid making barrel shaped bales. (See WEAVING IN THE WINDROW in Operating the Baler section.)

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.)

c) Baler drive roll wrappage.

Do not damage rubber strips when removing net wrap material.

d) Net splitting.

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

PP98408,0000169 -19-14OCT09-9/18


Symptom Problem Solution

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

Make sure splices are smooth.

Inspect and repair broken or damaged belt splices.

f) 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.)

g) Bale forming belts sticky from silage buildup.

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

h) Broken or damaged belt splices.

Repair belt splices.

j) 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.

Monitor-controller not in NET mode.

Put monitor-controller selector switch on NET position.

Net will not start to feed. (If cover is open, net will feed.)

Shock contacts end of bolt on upper plastic roller arm.

Replace bolt with 5 mm (0.20 in.) shorter bolt or grind end of bolt flush with nut. Repeat on both sides.

PP98408,0000169 -19-14OCT09-10/18


Symptom Problem Solution

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 buildup at rear of pan.

Net wrap pan is not contacting belts at rear of pan. Adjust pan to contact belts.

Holes worn in rear of pan catching net wrap.

Adjusting net pan pressure. (See ADJUSTING LOWER NET WRAP GUIDE in Service-Net Wrap section.)

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 in Service-Net Wrap section.)

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 damage or missing on MegaWide™ Plus pickup frame.

Install angle. (See your John Deere dealer)

PP98408,0000169 -19-14OCT09-11/18


Symptom Problem Solution

Net wrap not routed between steel and rubber roll .

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

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.

PP98408,0000169 -19-14OCT09-12/18


Symptom Problem Solution

Alarm Sounds. STOP and NET WRAP indicators are displayed on monitor-controller and alarm sounds when bale is wrapped correctly. E401 or E402 error codes will be displayed.

Switch activating flap is not adjusted or binding.

Adjust and correct binding or lube pivots. (See ADJUSTING NET WRAP SWITCH in Service-Net Wrap section).

PP98408,0000169 -19-14OCT09-14/18


Symptom Problem Solution

Net wrap loose around bale.

Inadequate tension on net.

Increase tension (See ADJUSTING NET WRAP STRETCH in Service-Net Wrap section.)

Net Wrap traveling over idler roll (#11) due to too large bale.

Ensure bales are not larger than 183 cm (72 in.) when measured. Reduce monitor size setting if necessary.

Make smaller bale. (See ADJUSTING SWITCH OVERSIZE BALE in Service-Baler section.)

V-belt idler out of adjustment.

Check idler. (See CHECKING V-BELT IDLER ADJUSTMENT in Service-Net Wrap section.)

Weak gas spring(s).

Check spring(s) for proper force.

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 (without slip clutch alert).

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 pan and belts.

Adjust rear of pan to contact belts at lower rear gate roller (see CHECKING and ADJUSTING LOWER NET WRAP GUIDE in Service Net Wrap section.)

PP98408,0000169 -19-14OCT09-15/18


Symptom Problem Solution

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

Buildup of crop stems, etc., in gate lower belt guide area.

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

Over size bale compresses crop build up in lower gate belt guide area.

Adjust oversize bale switch. (See ADJUSTING OVERSIZE BALE SWITCH in Service section.)

Remove buildup. In some crops, reducing PTO rpm will reduce buildup tendency. Ejecting bale with PTO running will reduce buildup in some conditions. (See ADJUSTING OVERSIZE BALE SWITCH in Service section.)

Actual bale size is larger than displayed diameter. Adjust bale size display to match actual diameter. (See ADJUSTING BALE DIAMETER DISPLAY in Service section.)

Oversize bale may allow some strands of net to wrap around number 11 idler roller.

Adjust oversize bale switch. (See ADJUSTING OVERSIZE BALE SWITCH in Service section.) Remove net from all rollers.

Actual bale size is larger than displayed diameter. Adjust bale size display to match actual diameter. (See ADJUSTING BALE DIAMETER DISPLAY in Service section.)

Too much pressure between net wrap pan channels and belts, causing net to become hot.

Check net pan pressure. (See CHECKING and ADJUSTING NET PAN PRESSURE in Service-Net Wrap section.)

If a net pan channel is bowed up, straighten to match other channels.

Extremely stemmy crops causing splitting or snagging.

Use more wraps of net wrap material.

Make sure splices are smooth.

Net wrap breaking due to excess tension.

Incorrect number of shims between pulley halves for net wrap being used.

See ADJUSTING NET WRAP STRETCH in Service-Net Wrap section.

Not enough wraps of net.

Adjust for at least two full wraps. More wraps in difficult crops like (Straw, corn stalks, etc.)

Cover does not stay open.

Weak gas spring(s).

Replace spring(s).

Net is not out to edge of bale. (Using edge to edge material)

Roll of net too narrow.

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

Roll of net wrap not center in baler.

Use centering plugs. See your John Deere dealer.

Overfilling ends of bale producing an hourglass shaped bale. Confirm net is to ends of bale in chamber. Net will move away from ends of bale after discharging bale.

Decrease windrow width, especially if equipped with MegaWide Plus pickup (468 and 468S).

PP98408,0000169 -19-14OCT09-17/18


Symptom Problem Solution

COVER-EDGE material not going over edge of bale.

Crop material blocking net wrap path.

Remove crop, check scraper, and cast gate filler adjustments.

Reduce rpm. (See BALING SHORT, DRY, SLICK CROPS in Operating the Baler.)

Belt tracking incorrect.

Be sure right-hand or left-hand end belts do not continuously contract 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).
