MAINTENANCE
Slip Clutch
Avoid overheating of the Slip Clutch by too long or too frequent slipping, as this can damage the friction plates
and limiter parts. When checking Slip Clutch for overheating, DO NOT touch with hand. Slip Clutch could be
extremely hot and cause severe burn.
If an adjustment is required, this may be done in the field by following the procedure outlined below. Following
these instructions will give maximum rated torque and long life
(Figure Mnt-0006) .
1. With the three Capscrews (8) backed out until the points are below the surface of the circular Adjusting Nut
(7), run Adjusting Nut up finger-tight, or slightly less than finger-tight.
2. Alternately tighten the hardened, cup point Capscrews (8) no more than one-half turn at a time until the
Capscrew heads “Bottom Out”. Do not over tighten the Capscrews nor completely flatten the Spring
Washers (5).
If the Hub is removed from the Shaft for any reason, the Shaft and Hub should be coated with a heavy grease
before reassembly to prevent Hub from freezing to Shaft.
Seasonal Slip Clutch Maintenance
It is important that the slip clutch slips when an
obstacle or load heavier than the setting is
encountered. Before using the cutter each season,
use the following procedure to make sure the slip
clutch will slip and give the overload protection
required.
1. Loosen Bolts (8) until gap between adjusting
nut (7) and guide ring is approximately 1/16”.
2. Attach machine to tractor, set engine at
approximately half throttle and quickly engage
PTO. This procedure will break slip clutch
facings loose and allow the proper torque to be
maintained.
3. Return the bolts to their original position as
described above.
NOTE: If machine sits outside longer than 30 days
and is exposed to rain and humid air, the clutches
should be removed from machine and stored in a
dry area. Slip Clutch facings will soak up moisture
and cause the metal plates to rust badly. When this
occurs, the break-away torque increases greatly
and damage to gearbox, driveline, or tractor PTO
can occur.
When attaching PTO yoke to tractor PTO shaft, it is important that spring-activated locking
collar slides freely and locking balls are seated in groove on PTO shaft. A loose shaft could
slip off and result in personal injury or damage to cutter.
