Operation

MAN1168 (5/27/2016)
5.
Connect cutter driveline to tractor PTO shaft,
making sure the spring-activated lock pin slides
freely and is seated in tractor PTO splined groove.
6.
Remove parking jack from the tongue and attach it
to the storage post on the front of the cutter.
Hydraulic Connection
1.
Inspect hydraulic hoses to ensure they are in good
condition.
2.
Clean the fittings before connecting them to the
tractor hydraulic ports.
3.
Attach the hydraulic hose from the cutter to the
tractor.
4.
Route the hose through the hose holder at the
hitch and be sure the hose can slide freely in the
holder. Do not allow hose slack to drag on the
ground or become caught on tractor protrusions.
5.
From the operator position, start tractor and raise
and lower deck several times to purge trapped air
from the hydraulic cylinder.
Interference Check
1.
Be sure that tractor 3-point lift links do not interfere
with hydraulic hoses, cutter driveline, or cutter
frame.
2.
Check for straight-ahead operation and at full-
turning angles. If there is any interference, remove
the lower lift links.
3.
Contact between tractor lift links and cutter parts
can cause damage, especially when turning.
CV Driveline Turning Limits
NOTICE
You must not exceed a turning angle of 80 degrees at
the head of the Constant Velocity driveline or damage
will occur.
To check for potential excessive turn angle:
1.
Disconnect driveline from tractor, start engine and
turn as far right or left as possible.
2.
Shut engine off, set parking brake, remove key,
and try to connect CV driveline to tractor. If it
cannot be connected, the angle is too severe.
3.
Restart engine and straighten angle slightly.
Repeat step 2 until driveline can be connected.
The point at which the driveline can be connected
is the maximum turn that should be made.
CONNECT CUTTER TO TRACTOR
(MOUNTED DS8.50 & DS10.50 & SEMI-
MOUNTED DSO8.50 & DSO10.50)
Tractor Adjustments
Before attaching tractor to cutter, install sway blocks or
sway chains, or adjust stabilizer bars. Refer to the trac-
tor operator's manual for instructions.
Install tractor front end weights as recommended by
the tractor manufacturer to provide 20% of weight on
front wheels.
A minimum 20% of tractor and equipment
weight must be on the tractor front wheels when
attachments are in transport position. Without this
weight, front tractor wheels could raise up result-
ing in loss of steering. The weight may be attained
with front wheel weights, ballast in tires or front
tractor weights. Weigh the tractor and equipment.
Do not estimate.
