The drive-train is protected from shock loads with a four 
plate slip-clutch. The slip-clutch must be capable of 
slippage during operation. Always do a “clutch run-in” 
operation at the beginning of each season and after long 
periods of inactivity to remove any oxidation that may 
have accumulated on the friction surfaces. Repeat 
“clutch run-in” instructions when moisture and/or 
condensation seizes the inner friction plates.

Refer to Refer to Figure 5-4:
1.

Using a pencil or other marker, scribe a line across the 
exposed edges of the clutch plates and friction

 discs.

2.

Carefully loosen each of the 8 spring retainer nuts by 
exactly 2 revolutions. It will be necessary to hold hex 
end of retainer bolt in order to count the exact 
number of revolutions.

3.

Start tractor and engage PTO drive for 2-3 seconds 
to permit slippage of the clutch surfaces. Disengage 
PTO, then re-engage a second time for 2-3 seconds. 
Disengage PTO, shut off tractor, and remove key. 
Wait for all components to stop before dismounting 
from tractor.

4.

Inspect clutch and ensure that the scribed markings 
made on the clutch plates have changed position. 
Slippage has not occurred if any two marks on the 
friction disc and plate are still aligned. A clutch that 
has not slipped must be disassembled to separate 
the friction disc plates. See “Clutch Assembly and 
Disassembly” on page 26.

5.

Tighten each of the 8 spring retainer nuts on the 
clutch housing exactly 2 revolutions to restore the 
clutch to the original 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 Figure 5-6 to adjust spring length.

See IMPORTANT NOTE above before disassembling 
clutch. After measuring and recording each spring length, 
remove spring retainer nuts (#1), springs (#2), and bolts 
(#3). Each friction disc (#4) must then be separated from 
the metal surface adjacent to it. Refer to the Parts Manual 
for a detailed parts breakdown.

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 thickness falls below 3/64" (1.1mm). If 
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. 

Refer to Figure 5-5 & Figure 5-6:
Reassemble each friction disc (#4) next to the metal plate 
it was separated from. Install bolts (#3) through the end 
plates and intermediate plates as shown. Place springs 
(#2) over bolts (#3) and secure with nuts (#1). 
Progressively tighten each spring retainer bolt until 
correct spring height “A” dimension is obtained.

IMPORTANT: Refer to Figure 5-6. Be Sure to 
measure and record length (“A”) of each clutch 
spring before disassembling clutch.
