To the Purchaser
This safety alert symbol identifies impor- tant
safety messages in this manual. When you see this
symbol, be alert to the possi- bility of personal
injury and carefully read the message that
follows. Right and left-hand sides are
determined by facing in the direction of forward
travel. Record your loader model and serial
number in the space provided on page 86. Your
dealer needs this information to give you prompt,
efficient service when you order parts or
attachments. Because John Deere sells its
products world-wide, U.S. units of measure are
shown with their respective metric equivalents
throughout this operator's manual. These
equivalents are the SI (International System)
Units of Measure.

Safety
BEFORE OPERATING 1. Read all decals and SAFETY
section of this manu- al.
2. Escaping fluid under pressure can have
sufficient force to penetrate the skin, causing
serious per- sonal injury. Before disconnecting
lines, be sure to relieve all pressure. Before
applying pressure to the system, be sure all
connections are tight and that lines, pipes and
hoses are not damaged. Fluid escaping from a very
small hole can be almost invisible. Use a piece
of cardboard or wood, rather than hands to search
for suspected leaks. If injured by escaping
fluid, see a doctor at once. Serious infection or
reaction can develop if proper medical treatment
is not administered immedia1ely.

  • Be sure no one is near tractor and loader.
  • Do not allow riders on tractor or loader.
  • Operate loader from operator's seat only.
  • Carry load low at all times.
  • Turn tractor at slow speeds.
  • Reduce tractor ground speed when traveling over
    rough terrain.
  • Avoid traveling over loose fiil, rocks and holes.
  • Do not overload loader. 13, Avoid working on
    inclines.
  • Drive slowly through gates and doors.
  • Avoid handling loose or shiftable loads.
  • Never use loader as a battering ram.

  • HANDLING ROUND BALES
  • Improper use of front-end loaders to handle round
    bales can result in iniury to the tractor
    operator from
  • the bale rolling back down the loader boom into
    the operator's station or -
  • a tractor roll-over accident caused by
    instability
  • when the bale is not carried low.
  • CAUTION Exercise extreme caution when using a
    front-end loader to handle round bales. Be
    careful and prevent bodily injury.
  • Even when using proper equipment, handling round
    bales can be hazardous. Follow the instructions
    shown in this manual and on the decals attached
    to the loader and round bale clamp.

  • HANDLING ROUND BALESContinued
  • Do not handJe round bales with the loader unless
    the specially designed John Deere round bale
    clamp is installed. Without the clamp, the bale
    can fall on the operator when the loader is
    raised.
  • To avoid handling and stability problems, do not
    exceed a round bale weight of 2000 pounds (907
  • The tractor must be equipped with a roll-over
    protective structure to prevent operator injury
    in case of a tractor roll-over accident.
  • The tractor must have maximum rear ballast per
    wheel and maximum tread width. See Rear Tread
    and Rear Ballast on page 11.'
  • Reduce the tractor ground speed. Carry the bale
    as low as possible and maintain adequate
    visibility and ground clearance at all times.
  • Jerky operation causes tractor-loader
    instability. Operate the loader controls
    smoothly.

9. When handling round bales on a slope, approach
the bale with the tractor facing uphill.
  1. Never use the tractor-loader to stop a rolling
    bale.
  2. Obey all safety messages under Operating on
    pages 3 and 4.

  • SERVICE AND STORAGE
  • Lower bucket or attachment to ground, shut off
    tractor engine and relieve pressure in hydraulic
    system before adjusting, lubricating, or
    servicing loader.
  • Check hoses, fasteners and other parts for dam-
    age. Make necessary repairs.
  • Escaping fluid under pressure can have
    sufficient force to penetrate the skin, causing
    serious per- sonal injury. Before disconnecting
    lines, be sure to relieve all pressure. Before
    applying pressure to the system, be sure all
    connections are tight and that lines, pipes, and
    hoses are not damaged. Fluid escaping from a very
    small hole can be almost invisible. Use a piece
    of cardboard or wood, rather than hands to search
    for suspected leaks.
  • If injured by escaping fluid, see a doctor at
    once. Serious infection or reaction can develop
    if proper medical treatment is not administered
    immediately.

  • TRANSPORTING
  • Reduce tractor ground speed when transporting a
    load.
  • Carry load as low as possible and maintain ade-
    quate visibility and ground clearance at all
    times.
  • Take extra care when traveling over rough terrain
    or on a slope.
  • When driving the tractor-loader on a road or
    high- way at night or during the day, use
    accessory lights and devices for adequate
    warning to operators of other vehicles. In this
    regard, check local govern- ment regulations.

REAR BALLAST CAUTION To prevent tractor damage
and maintain loader-tractor stability, add rear
ballast as outlined below. Ballast
recommendations are a) For tractors with 80-inch
(2.03 m) rear tread setting -
TRACTOR 2520 3020 (long wheelbase) 4000 All Other
Models
BALLAST PER WHEEL 400 lbs. (181.4 kg) 200 lbs.
(90.7 kg) 200 lbs. (90.7 kg) 0
b) If minimum rear tread width is necessary, use
700 additional pounds (317.5 kg) per wheel. NOTE
The amount of ballast recommended above is
intended to help maintain stability and provide
adeguate traction during normal loader opera-
tion with materials-handling and manure
buckets. Additional ballast up to maximum lire
carrying capacity should be added, if neces-
sary, when operating tractor and loader on uneven
terrain, when operating loader with grapple fork
or haystacker attachment, or to improve
traction. Refer to tractor operator's manual to
install ballast.

Aftaching the Loader 15 HYDRAULIC
CONNECTIONS CAUTION Escaping fluid under
pressure can have sufficient force to penetrate
the skin, causing serious personal injury. Be-
fore disconnecting lines, be sure to relieve all
pressure. Before applying pressure to the system,
be sure all connections are tight and that
lines, pipes, and hoses are not damaged. Fluid
escaping from a very small hole can be almost
invisible. Use a piece of cardboard or wood,
rather than hands, to search for suspected
leaks. If injured by escaping fluid, see a doctor
at once. Serious infection or reaction can de-
velop if proper medical treatment is not
administered immediately.
APin Hole Leak
IMPORTANT use Teflon tape on all pipe threads.
Over-tightening O-ring fittings re- sults in
leakage. Keep Quik-Couplets clean.
  • Remote Cylinder Control Valve Operation
  • Connect hoses from top oil tube and second oil
    tube to remote cylinder control valve on right
