Blade Selection - Woods DS8.30E Manuel De L'opérateur

Pull-Type Units
To adjust cutter for normal mowing, select a cutting height (example: 101.6 mm
(4-inches). Blades are approximately 31.8 mm (1-1/4") above bottom of cutter.
Dimension A plus 31.8 mm (1-1/4") equals cutting height.
Using hydraulic cylinder, raise or lower the tailwheel and set position A to 69.9
mm (2-3/4 inches) to achieve a 101.6 mm (4") cutting height.
Loosen the jam nut on the attitude rod that runs from the tongue to the tail-
wheel. Adjust rod in or out until position B is approximately 6.4 to 12.7 mm (1/4
to 1/2 inches) more than position A. Refer to Figure 9.

Cutting Height Adjustment
Mounted Units
To adjust cutter for normal mowing, select a cutting height (example: 101.6 mm
(4"). Blades are approximately 31.8 mm (1-1/4") above the bottom of cutter.
Dimension A plus 31.8 mm (1-1/4") equals cutting height.
Adjust tractor 3-point hitch to obtain a distance of 69.9 mm (2-3/4 inches) at posi-
tion "A" to obtain a 101.6 mm (4") cutting height. See Figure 9.
Adjust the position of the tailwheel arms between the tailwheel height adjust-
ment brackets to obtain a distance greater than 69.9 mm (2-3/4") at position
"B"
Adjust top link to provide 38.1 mm (1-1/2") of clearance between the break link
(2) and the rear lift links. See Figure 9. This clearance will allow the cutter to
float over uneven terrain.
ATTITUDE ADJUSTMENT (PULL-TYPE)
Normal Mowing
For the most economical power use and best cutting results, the cutter should
be from 12.7 to 19 mm (1/2" to 3/4") higher at the rear than at the front.
For grass and weed mowing, adjust cutter to run level or with the front slightly
lower.
Shredding
For shredding, it is better to set rear of cutter slightly lower than the front. How
much lower depends on the material to be shredded. Determine the best set-
ting for your situation by experimenting. Use a slow ground speed for better
shredding.

BLADE SELECTION

There are two blade options: standard suction blades and flat double-edge
blades.
The standard suction blade is a general use, multi-purpose blade.
The double-edge blade requires less power because it does not mulch or recut
material. It is designed for use in areas where blade wear is a problem. Sandy
soils are extremely hard on blades.
Blade rotation, viewed from top of cutter, is clockwise for the right crossbar, and
counter-clockwise for the left crossbar.
When one cutting surface of a double-edge blade is worn, the opposite one
may be used by placing the blade on a crossbar of the opposite rotation.
Blades from the right may be used on the left. Blades from the left may be used
on the right.
13 Operation
Blades must be moved in pairs. Never use one new blade and one used blade
on a crossbar.
TRACTOR OPERATION
Use care when operating around tree limbs and other low objects.
Use care and reduce ground speed on rough terrain. Always watch for hidden
hazards.
Being knocked off or falling off tractor can result in serious injury or death.
Only use a tractor with a Roll Over Protective Structure (ROPS) and seat belt.
Securely fasten seat belt before starting tractor.
The cutter is operated with tractor controls. Engage the PTO at a low rpm to
prevent excessive loads on the cutter drive system. Increase throttle to proper
PTO speed (540 rpm).
Be sure operator is familiar with all controls and can stop tractor and cutter
quickly in an emergency. The operator should give complete, undivided atten-
tion to operating tractor and cutter.
OPERATING TECHNIQUE
Power for operating the cutter is supplied by the tractor PTO. Operate PTO at
540 rpm. Know how to stop the tractor and cutter quickly in an emergency.
Engage PTO at a low engine rpm to minimize stress on the drive system and
gearbox. With PTO engaged, raise PTO speed to 540 rpm and maintain
throughout cutting operation.
Gearbox protection is provided by a slip clutch with replacement fiber disc. The
slip clutch is designed to slip when excessive torsional loads occur.
Move slowly into material. Adjust tractor ground speed to provide a clean cut
without lugging the tractor engine. Use a slow ground speed for better shred-
ding.
Proper ground speed will depend on the terrain and the material's height, type,
and density.
Normally, ground speed will range from 3 to 8 km/h (2 to 5 mph). Tall, dense
material should be cut at a low speed; thin, medium-height material can be cut
at a faster ground speed.
Always operate tractor PTO at 540 rpm to maintain blade speed and to pro-
duce a clean cut.
Under certain conditions tractor tires may roll down some grass and prevent
cutting at the same height as the surrounding area. When this occurs, reduce
your ground speed but maintain PTO at 540 rpm. The lower ground speed will
permit grass to rebound partially.
Cutter Operation
When beginning operation of the cutter, make sure that all persons are in a
safe location. Slowly move into the material with the tractor PTO set at 540
rpm.
Mowing Tips
WARNING

Look down and to the rear and make sure area is clear before operat-
ing in reverse.

Do not operate or transport on steep slopes.

Do not stop, start, or change directions suddenly on slopes.

Use extreme care and reduce ground speed on slopes and rough ter-
rain.

Watch for hidden hazards on the terrain during operation.
CAUTION CAUTION

Stop power unit and equipment immediately upon striking an
obstruction. Turn off engine, remove key, inspect, and repair any damage
before resuming operation.
Maximum recommended ground speed for cutting or shredding is 10 km/h (6
miles per hour). Adjust tractor ground speed by using higher or lower gears to
provide a clean cut without lugging tractor engine.
Tall material should be cut twice. Cut material higher the first pass. Cut at
desired height at 90 degrees the second pass.
Remember, sharp blades produce cleaner cuts and use less power.
