Owner Service 19
MAN0805 (4/30/2009)
OWNER SERVICE
The information in this section is written for operators
who possess basic mechanical skills. If you need help,
your dealer has trained service technicians available.
For your protection, read and follow the safety informa-
tion in this manual.
Keep all persons away from operator control
area while performing adjustments, service, or
maintenance.
Before working underneath, disconnect drive-
line from tractor, lower wings to ground, raise cut-
ter, and pin transport bar in raised position. Attach
parking jack and lower to ground. Securely block
all four corners of center section and each wing
with jack stands. Blocking up prevents the cutter
from dropping due to hydraulic leak down, hydrau-
lic system failure, or mechanical component fail-
ure.
Service and maintenance work not covered in
OWNER SERVICE must be done by a qualified
dealership. Special skills, tools, and safety proce-
dures may be required. Failure to follow these
instructions can result in serious injury or death.
Before servicing, adjusting, repairing or unplug-
ging, stop tractor engine, place all controls in neu-
tral, set park brake, remove ignition key, and wait
for all moving parts to stop.
Never perform service or maintenance with
engine running.
If you do not understand any part of this manual
and need assistance, see your dealer.
Always wear relatively tight and belted clothing
to avoid entanglement in moving parts. Wear
sturdy, rough-soled work shoes and protective
equipment for eyes, hair, hands, hearing, and head;
and respirator or filter mask where appropriate.
BLOCKING METHOD
To minimize the potential hazards of working under-
neath the cutter, follow these procedures:
Before performing any service or maintenance,
lower equipment to ground or block securely, turn
off engine, remove key, and disconnect driveline
from tractor PTO.
Never go underneath equipment (lowered to the
ground or raised) unless it is properly blocked and
secured. Never place any part of the body under-
neath equipment or between moveable parts even
when the engine has been turned off. Hydraulic
system leak down, hydraulic system failures,
mechanical failures, or movement of control levers
can cause equipment to drop or rotate unexpect-
edly and cause severe injury or death. Follow Oper-
ator's Manual instructions for working underneath
and blocking requirements or have work done by a
qualified dealer.
Do not position jackstands under wheels, axles, or
wheel supports. Components can rotate and cause cut-
ter to fall.
1. Jackstands with a load rating of 1000 lbs. or more
are the only approved blocking device for this
cutter. Install jackstands (shown by Xs in Figure 5)
under the cutter before working underneath unit.
2. Consider the overall stability of the blocked unit.
Just placing jackstands underneath will not ensure
your safety.
The working surface must be level and solid to
support the weight on the jackstands. Make sure
jackstands are stable, both top and bottom. Make
sure cutter is approximately level.
3. With full cutter weight lowered onto jackstands, test
blocking stability before working underneath.
4. If cutter is attached to tractor when blocking, set
the brakes, remove key, and block cutter before
working underneath.
5. Securely block rear tractor wheels, in front and
behind. Tighten tractor lower 3-point arm anti-sway
mechanism to prevent side-to-side movement.
