Net Wrap or B-Wrap Difficulties

Net wrap material wrapped around the rubber feed roll.

Do not cut the net wrap material from the rubber feed roll. Any knife cuts in the rubber roll covering can result in more frequent wrapping around the roll and can require roll replacement. (See Correct Net Wrap Feeding Problems in Service—Net Wrap section.)

Brake torque too low.

Adjust brake (See Check And Adjust Net Wrap Feed Roll Brake in Service—Net Wrap section)

 

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

Bend lower portion of the front sheet to obtain 3—6 mm (0.12—0.24 in) clearance between the front sheet and rubber roll. (See Check Front Sheet To Rubber Roll Clearance in Service—Net Wrap section.) (See your John Deere dealer or qualified service provider.)

 

Net looped away from the steel roll and contacting the counterknife angle.

Adjust brake (See Check And Adjust Net Wrap Feed Roll Brake in Service—Net Wrap section)

 

Counterknife angle is not raising high enough.

Check idler. (See Check And Adjust V-Belt Idler Tension in Service—Net Wrap section.)

 

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

Dust the rubber drive roll and outside of the net wrap with oil-dry granules.

 

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

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

 

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

Clean and polish the upper pan surface with SCOTCH-BRITE® or ultra fine sandpaper. Polish marks must be parallel to movement of mesh. (See Clean and Inspect Lower Net Wrap Guide in Service-Net Wrap section.)

 

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

Check for hole wear in the side panel. (See Check Hole Wear In Surface Wrap Side Panel in Service—Net Wrap section.)

Weld key stock to the side panel. (See your John Deere dealer or qualified service provider.)

 

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

Be sure that the tape across the cover hinge joint at the top of cover is intact. Replace if necessary. (See your John Deere dealer or qualified service provider.)

Clean rolls. (See Clean and Inspect Lower Net Wrap Guide in Service- Net Wrap section.)

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

 

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

Check for contact between bolt heads. (See Check for Poor Net Cut-off (Left-Hand Side of Baler) in Service—Net Wrap section.)

Bend out left-hand counterknife arm. To align the idler, remove the washer between the idler sheave and the left-hand counterknife arm. (See your John Deere dealer or qualified service provider.)

Grind the net pan bolt head or grind chamfer at the front edge of the net pan strap.

 

Nicks or cuts on the rubber feed roll.

Repair cuts or nicks. (See Repair Cuts On Rubber Feed Roll in Service—Net Wrap section.)

 

Lower the net wrap guide (pan) not contacting belts.

Adjust net pan pressure. (See Check And Adjust Net Pan Pressure in Service—Net Wrap section.)

Straighten net pan angle. (See Check And Straighten Net Pan Angle in Service—Net Wrap section.)

 

Net switch plate attached to the gate frame can cause the right-hand side of net to hesitate and wrap on rubber roll.

Remove plate if slack belts do not cause net switch error codes.

 

Counterknife angle not holding the net wrap.

See Adjust Net Wrap Counterknife in Service—Net Wrap section.

Clean brush. (See Install And Adjust Net Wrap Brush in Service—Net Wrap section.)

 

Feed roll pressure set too high.

Adjust feed roll pressure. (See Adjust Net Wrap Feed Roll Pressure in Service—Net Wrap section.)

 

Long or uneven tails after cut-off.

Remove and clean brush behind cut-off knife.

Net wrap is wrapped around No. 8 roll spirals

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

Adjust knife-to-counterknife angle clearance. (See Adjust 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 Service—Net Wrap 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. (See Guideline To Form A Good Bale in Operating Baler Application section.)

 

Crop deflectors (belting) bent to the rear, splitting net approximately 75 mm (3 in) from the edge of net. Loose tails can wrap on #8 spirals.

Reverse or replace deflectors.

Remove if not baling cornstalks, milo, or sorghum.

Trim deflectors. (See your John Deere dealer or qualified service provider.)

Excess paint or paint runs on top surfaces of the net pan are rough and can cause feeding problems.

Remove excess or rough paint and polish.

Bale not wrapped. (No Alarm, Stop, And Net Wrap indicators not displayed).

Net wrap fed to other areas of the machine:

Locate and remove the net wrap material before making the next bale. Otherwise, improper belt tracking and further incorrect feeding can result, if the 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 the 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 1829 mm (72 in) or smaller. (Measure a bale to check actual bale size. Ensure that bale size is 1829 mm (72 in) or less.)

Avoid making barrel shaped bales. (See Guideline To Form A Good Bale in Operating Baler Application section.)

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

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

Check for cut or damaged belt surface. Trim loose belt edges, repair, or replace. (See Repair Belts in Service—Baler section.)

 

C) Baler drive roll wrappage.

Do not damage rubber strips when removing the net wrap material.

 

D) Net splitting.

See Net Wrap Is Split Around Bale Or Stays Behind The Pickup in this section.

 

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

Make sure that splices are smooth.

Inspect and repair broken or damaged belt splices.

 

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

Remove crop buildup from lower gate area. In some crops, reducing PTO rpm while baling reduces buildup tendency. Ejecting bale with PTO running reduces buildup in some conditions. (See Bale 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.

 

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

To improve the belt tracking, adjust belt tracking or move the belt to another location. (See Adjust Belt Tracking in Service—Baler section.)

Remove wrappage on baler rolls.

 

Actuator or controller disconnected.

Check connections and wires.

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

See Bale Not Wrapped (Cut-Off 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 is placed between the layers of net wrap or outside the wrapping.

Adjust net wrap delay time. (See Adjust Net Wrap Settings in Operating Baler Application section.)

Alarm Sounds. Stop And Net Wrap indicators are displayed on monitor-controller and alarm sounds when the bale is wrapped correctly. Error message code is displayed.

Switch activating flap is not adjusted or binding.

Adjust and correct binding or lube pivots. (See Check and Adjust Net Wrap Switch in Service—Net Wrap section).

 

Net wrap material is not cut off cleanly.

Sharpen the net wrap cut-off knife. (See Sharpen Net Wrap Knife in Service—Net Wrap section.)

Cover must be closed for best cut-off.

 

Cutoff angle out of adjustment.

Adjust. (See Adjust Net Wrap Counterknife Arm in Service—Net Wrap section).

Remove and clean brush.

 

Net wrap tails holds net switch actuator down.

See solutions previously mentioned from the top of this page.

Net wrap loose around bale.

Inadequate tension on net.

Increase tension (See Adjust Net Wrap Stretch in Service—Net Wrap section.)

 

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

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

Make smaller bale. (See Adjust Oversize Bale Switch in Service—Baler section.)

 

V-belt idler out of adjustment.

Check idler. (See Check and Adjust Net Wrap V-Belt Idler Tension in Service—Net Wrap section.)

 

Weak gas springs.

Too many layers of the net wrap applied.

No more than three layers of the net wrap are needed. Excess layers of net can appear to be loose.

Varying number of layers of net from one bale to the next.

Varying PTO speed while applying net from one bale to the next.

Be sure that PTO slip clutch alert sensor is turned on.

Maintain rated PTO speed while applying net to the bale. If difficult crop conditions require varying PTO speed while baling, return to rated speed for applying the net.

 

Bale size and shape not uniform.

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

If applying net to a smaller bale with override switches, the small bale has a higher number of the net wrap layers unless the control unit is readjusted.

 

Too much clearance between net wrap guide pan and belts.

Adjust rear of the pan to contact belts at the lower rear gate roller (see Check and Adjust Lower Belt Guides in Service—Net Wrap section.)

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

Buildup of crop stems in gate lower belt guide area.

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

 

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

Adjust oversize bale switch. (See Adjust Oversize Bale Switch in Service—Baler section.)

Remove buildup. In some crops, reducing PTO rpm reduces buildup tendency. Ejecting bale with PTO running reduces buildup in some conditions. (See Adjust Oversize Bale Switch in Service—Baler section.)

Actual bale size is larger than displayed diameter. Adjust bale size display to match actual diameter. (See Calibrate Bale Diameter Sensor in Baler Application Service section.)

 

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

Adjust oversize bale switch. (See Adjust Oversize Bale Switch in Service—Baler section.) Remove net from all rollers.

Actual bale size is larger than displayed diameter. Adjust bale size display to match actual diameter. (See Calibrate Bale Diameter Sensor in Baler Application Service section.)

 

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

Check net pan pressure. (See Check And Adjust Net Pan Pressure in Service—Net Wrap section.)

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

 

Stemmy crops causing splitting or snagging.

Use more wraps of the net wrap material.

 

Clearance exceeds 5 mm (0.20 in) between lower guide crossbar and belt guide straps. (Belts track underneath belt guides and split net.)

Check for proper clearance. (See Check and Adjust Lower Belt Guides in Service—Net Wrap section.)

 

Insufficient clearance between lower guide crossbar and belt guide straps. (Net contacts belt guides.)

Check for proper clearance. (See Check and Adjust Lower Belt Guides in Service—Net Wrap section.)

 

Clearance between lower guide crossbar and belt guide straps is 3—4 mm (0.12—0.16 in) and causes crop to hairpin around belt guides and split net in cornstalks, cane, or sorghum crops.

Set clearance between lower guide crossbar and belt guide strap to 4—5 mm (0.16—0.20 in). (See Check and Adjust Lower Belt Guides in Service—Net Wrap section.)

 

Belts not tracking correctly.

See Adjust Belt Tracking in Service—Baler section.

 

Material snagging on splices or pins.

Make sure that splices are smooth.

Net wrap breaking due to excess tension.

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

See Adjust Net Wrap Stretch in Service—Net Wrap section.

 

Not enough net wrap layers.

Adjust for at least two full layers of the net wrap. More net wrap layers needed in difficult crops like straw and corn stalks.

Cover does not stay open.

Weak gas springs.

Replace springs.

Cover will not open.

Brake lever not engaged and contacts shock mounting.

Engage brake lever before closing cover.

Add washers to brake lever pivot pin to reduce lever end play.

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

Roll of net too narrow.

See your John Deere dealer or qualified service provider. Use only approved material for best results.

 

Roll of net wrap not center in baler.

Use centering plugs. See your John Deere dealer or qualified service provider.

 

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

Decrease windrow width, especially if equipped with theMegaWide™ Plus pickup.

Cover-Edge™ material not going over edge of bale.

Crop material blocking the net wrap path.

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

Reduce the rpm. (See Bale 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 must 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).

Approximately 250 mm (10 in) of CoverEdge™ net is cut or torn at the bale edge on one or both sides.

When distance (1—3 mm [0.04—0.12 in]) between lower rear corner of gate casting and side sheet exceeds 3 mm (0.12 in), gate casting can catch and damage net during discharge.

Check distance between lower rear corner of gate casting and side sheet by placing feeler gauge against the side sheet. If 3 mm (0.12 in) distance is exceeded:

1. Remove, clean, reinstall, and recheck distance.

2. Heat and bend lower rear corner with 1—3 mm (0.04—0.12 in) of the side sheet.

3. Replace gate casting.

Metal strip not detected during a B-Wrap cycle.

Sensor not adjusted properly.

Ensure B-Wrap sensor is adjusted within specification. (See Adjust B-Wrap Sensor in Operating the Baler section.)

 

Net not feeding properly causing metal strip not to pass the sensor.

Make sure that there is no buildup of net on the left-hand side of the net system and baler.

B-Wrap tail too long or short after Velcro strips.

B-Wrap cut position needs to be adjusted.

If tail length is too long, decrease cut parameter. If tail length is too short, increase cut parameter. (See Adjust Cut Position in Adjust B-Wrap Settings in Operating Baler Application section.)

Overlap of breathable section of wrap is oriented incorrectly (not between noon and six o’clock when looking at the left-hand side of bale).

B-Wrap seam orientation offset needs to be adjusted.

Increase orientation parameter if the bale needs to rotate counterclockwise when looking at the left-hand side of the bale. Decrease orientation parameter if the bale needs to rotate clockwise when looking at the left-hand side of the bale. (See Adjust Bale Orientation in Adjust B-Wrap Settings in Operating Baler Application section.)

 

PTO is not turned off before ejecting the bale in non-Automation mode.

Turn off PTO when beep sequence reaches end of countdown. (See Monitor Display for B-Wrap Baling in Operating Baler Application section.)

 

PTO is not turned off before ejecting the bale in Automation mode.

Ensure that the Auto-PTO Off check box is selected on the Automation settings page. (See Enable Auto-PTO Off for B-Wrap Automation in Operating Baler in Automation Mode section.)
