Seasonal Lubrication
In addition to the daily recommended lubrication, a more
extensive application is recommended seasonally.
1.
Fill CV double yokes with 20 pumps of grease with
the joints in a straight line.
2.
Articulate CV body to maximum angle several times
to ensure full coverage of joints.
3.
Place joints in the straight position and a add 10
additional pumps of grease to both joints.
4.
Wipe telescoping drive clean of all old grease and
contaminants.
5.
Add a thin layer of new grease over telescoping
drive.
BLADES
■ Before working underneath, read manual
instructions, securely block up, and check sta-
bility. Secure blocking prevents equipment from
dropping due to hydraulic leak down, hydrau-
lic system failure, or mechanical component
failure.
Blade Removal (Figure 6)
Figure 6.
Blade Assembly
1.
Disconnect driveline from tractor PTO.
2.
Raise cutter and block securely (see Figure 5).
3.
Align crossbar (12) with blade access hole in the
cutter frame. Remove cap screw (23), blade pin lock
clip (6), keyhole plate (5), spacer (15), and shims (2
& 3). Carefully drive blade pin (21) out of crossbar.
4.
Rotate crossbar and repeat for opposite blade.
■ If blade pin (21) is seized in crossbar and extreme
force will be needed to remove it, support cross-
bar from below to prevent gearbox damage.
Blade Installation (Figure 6)
■ Your dealer can supply genuine replacement
blades. Substitute blades may not meet orig-
inal equipment specifications and may be
dangerous.
■ Crossbar rotation has clockwise rotation on left
gearbox and counterclockwise rotation on the
right and center gearboxes 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 (21) for nicks or gouges, and if you
find any replace the blade pin.
2.
Insert blade pin through the blade. Blade should
swivel on blade pin; if it doesn’t, determine the
cause and correct.
3.
Align crossbar (12) with blade access hole in cutter
frame. Make sure blade offset is down away from
cutter.
4.
Insert blade pin (21) through blade. Push blade pin
through crossbar.
5.
Install shims (2 & 3) and spacer (15) over blade pin.
NOTE:
Only use enough shims to allow keyhole
plate (5) to slide into blade pin groove.
6.
Install blade clip (6) over keyhole plate and into
blade pin groove.
7.
Secure into position with cap screw (23). Torque
cap screw to 85 lbs-ft.
8.
Grease pin via zerk at end of pin.
9.
Repeat steps for opposite side.
NOTE:
Blade should be snug but should swivel on
pin without having to exert excessive force. Blade
should not move more than a 1/4 inch up or down
at the tip. Keep any spacers not used in the installa-
tion as replacements or for future installation.
