SERVICING BLADES

Removing Blades (Figure 12)
NOTICE
■
If blade pin (9) is seized in crossbar and extreme force will be
needed to remove it, support crossbar from below to prevent gearbox
damage.
Figure 12
1.
Disconnect driveline from tractor PTO.
2.
Raise cutter and block securely. (See Figure 11).
3.
Align crossbar (5) with blade access hole in the cutter frame. Remove
cap screw (27), blade pin lock clip (13), keyhole plate (12), and shims (10
& 11). Carefully drive blade pin (9) out of crossbar.
4.
Rotate crossbar (5) and repeat for opposite blade.
Installing Blades
CAUTION

Your dealer can supply genuine replacement blades. Substitute
blades may not meet original equipment specifications and may be dan-
gerous.
NOTICE
■
Crossbar rotation has counterclockwise rotation on left gearbox
and clockwise rotation on the right gearbox when looking down on cutter.
Be sure to install blade cutting edge to lead in correct rotation.
NOTE: Always replace or sharpen both blades at the same time.
1.
Inspect blade pin (9) for nicks or gouges, and if you find any, replace the
blade pin.
2.
Insert blade pin through the blade (6). Blade should swivel on blade pin; if
it doesn't, determine the cause and correct.
3.
Align crossbar (5) with blade access hole in cutter frame. Apply a liberal
coating of Never Seez or equivalent to blade pin and crossbar hole. Make
sure blade offset is away from cutter. Push blade pin through crossbar.
Pin should rotate freely prior to installing blade clip (13).
4.
Install shims (10 & 11) over blade pin.
NOTE: Only use enough shims to allow keyhole plate (12) to slide into
blade pin groove.
5.
Install blade clip (13) over keyhole plate and into blade pin groove.
6.
Secure into position with cap screw (27). Torque cap screw to 115 N-m
(85 lbs-ft).
7.
Repeat steps for opposite side.
NOTE:
Blade should be snug but should swivel on pin without having
to exert excessive force. Keep any spacers not used in the installation as
replacements or for future installation.
Sharpening Blades
NOTICE
■
When sharpening blades, grind the same amount on each blade to
maintain balance. Replace blades in pairs. Unbalanced blades will cause
excessive vibration, which can damage gearbox bearings. Vibration may
also cause structural cracks to cutter.

1.
Sharpen both blades at the same time to maintain balance. Follow
original sharpening pattern.
2.
Do not sharpen blade to a razor edge—leave at least a 1.6 mm (1/16")
blunt edge.
3.
Do not sharpen back side of blade.

ADJUSTING SLIP CLUTCH
The slip clutch is designed to slip so that the gearbox and driveline are pro-
tected if the cutter strikes an obstruction. A new slip clutch or one that has been
in storage over the winter may seize. Before operating the cutter, make sure it
will slip by performing the following operation:
DS8.30E - 3-Point Mounted
1.
Turn off tractor engine and remove key.
2.
Loosen nuts on springs until the springs can rotate freely, yet remain
secure on the bolts.
3.
Mark outer plates of slip-disc clutch as shown in Figure 14.
4.
Securely attach implement to the tractor and start the tractor.
5.
Engage PTO for several seconds then quickly disengage it.
6.
Turn tractor off and remove key.
7.
The friction lining plates should have "slipped". Check the marks placed
on the outer plates of the slip-disc clutch in step 3 to make sure this is the
case.
8.
If clutch does not slip, check assembly for oil grease and debris. Clean if
necessary.
9.
Reassemble clutch and tighten bolts no more than 1/8 of a turn at a time
until desired setting of 32 mm (1.26") is achieved.
10.
If excessive slippage continues, check lining plates for excessive wear.
They are 3.2 mm (1/8") thick when new and should be replaced after 0.8
mm (1/32") of wear to ensure proper operation.
DS8.30E Pull-Type
DS10.40E Pull-Type
DS10.40E 3-Point Mounted
1.
Turn off tractor engine and remove key.
2.
Remove driveline from tractor PTO.
3.
Loosen six 10 mm cap screws (6) to remove all tension from Belleville
spring plate (5).
4.
Hold clutch hub (3) solid and turn shaft to make sure clutch slips.
5.
If clutch does not slip freely, disassemble and clean the thrust plate faces
(4), flange yoke (1), and clutch hub (3).
6.
Reassemble clutch. Tighten Belleville spring (5) until it is against the
thrust plate (4) of the clutch, and then back off each of the six nuts by two
full revolutions. The gap between Belleville spring and thrust plate should
be 3.2 mm (1/8") as shown in Figure 14.
7.
If a clutch continues to slip when the spring is compressed to 3.2 mm
(1/8"), check friction discs (2) for excessive wear. Discs are 3.2 mm (1/8")
when new. Replace discs after 1.6 mm (1/16") wear. Minimum disc
thickness is 1.6 mm (1/16").
