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.

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

(belts). (See Check for Bent Rubber Crop Deflectors in Service—Net
Wrap section.)
Remove deflectors if
not baling cornstalks, milo, or sorghum. Trim deflectors. (See your
John Deere dealer.)
|
| |
Net wrap material improperly routed, or too much of
the end loop started through feed rolls when threading.
|
Route and thread the
net wrap correctly. (See Load Net Wrap Material in Preparing Baler
for Net Wrap section.)
|
|
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.

|
| |
Nicks and burrs on spirals.
|
Remove burrs with a
hand file.

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

|
| |
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.
|
| |

some crops, reducing PTO rpm reduces buildup tendency. Ejecting bale
with PTO running reduces buildup in some conditions.
Install Build-Up Reduction
Scraper Kit. (See Attachments section.)
|
| |

tension by adding shims between pulley halves. (See Adjust Net Wrap
Stretch in Service—Net Wrap section.)
|
| |

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.)
|
|
