4. Inspect the clutch and ensure that the scribed mark-
ings made on the clutchplateshave changed position.
If any two marks on a friction disk and plate are still
aligned, such indicates that slippage has not occurred
and the clutch must be disassembled to separate the
friction disks, see "Clutch Assembly and Disassem-
bly", on page 18.
5. Tighten each of the8 spring retainer nuts on the clutch
housing EXACTLY 2 revolutions to restore the original
clutch setting pressure.
6. The clutch should be checked during the first hour of
cutting and periodically each week. An additional set
of scribe marks can be added to check for slippage.
See "Clutch Assembly and Disassembly", on page
18, to adjust for proper spring length.
Eurocardan Clutch Assembly &
Disassembly
If the clutch run-in procedure, see "Clutch Run-In"on
page 17, indicated that one or more of the friction disks did
not slip, the clutch must be disassembled to separate the
friction discs. Refer to the Parts Section of this manual for a
detailed parts breakdown.
Refer to Figure 5-3:
Disassembly of the clutch is simply a matter of first remov-
ing the spring retainer nuts (#1), springs (#2) and bolts
(#3) from the assembly. Each friction disc (#4) must then
be separated from the metal surface adjacent to it. Inspect
all parts for excessive wear and condition. Clean all parts
that do not require replacement.
The original friction disc thickness is 1/8" (3.2mm) and
should be replaced if the thickness falls below 3/64"
(1.1mm). If the clutches have been slipped to the point of
"smoking", the friction discs may be damaged and should
be replaced. Heat build-up may also affect the yoke joints.

Install new friction discs if needed and reassemble all com-
ponents in proper order. Progressively tighten each spring
retainer bolt until the spring length is 1.010 inches,
Figure 5-4.
Storage
At the end ofthe working season or whenthe cutter will not
be used for a long period, it is good practice to clean off
any dirt or grease that may have accumulated on the cut-
ter and any of the moving parts.
1. Clean the cutter as necessary.
2. Check the blades for wear and replace if necessary.
3. Inspect the cutter for loose, damaged or worn parts
and adjust or replace as needed.
4. Lubricate as noted in Lubrication, starting on page 21.
5. Store the cutter inside if possible for longer cutter life.
6. Repaint parts where paint is worn or scratched to pre-
vent rust. Ask your dealer for Aerosol Land Pride
Beige touch-up paint #821-011C.
