guardrails, concrete abutments, and tree
stumps. Such an impact could cause broken
objects to be thrown outward at very high
velocities. To reduce the possibility of property
damage, serious injury, or even death, never
allow the cutting blades to come in contact with
such objects.
•
Stop cutter and tractor immediately upon
striking an obstruction. Turn engine off, remove
key, then inspect and repair any damage before
resuming operation.
•
Stay alert for uneven terrain, holes, rocks, roots
and other hidden hazards. Keep away from
drop-offs and hazards that could cause rollover.
Use extreme care and maintain minimum
ground speed when transporting or operating
on hillsides, over rough ground and when
operating close to ditches or fences. Be careful
and slow down when turning sharp corners and
changing direction on slopes. Do not start or
stop suddenly on slopes and avoid operating
on steep slopes. In extremely uneven terrain,
rear wheels weights, front tractor weights,
and/or tire ballast should be used to improve
stability.
•
Drive Rotary Cut Mower diagonally over sharp
dips and avoid sharp drops to prevent tractor
and Rotary Cut Mower from “hanging up”.
Always cut downward on slopes, never cut
across the face. Always check tractor manual
for proper use on slopes. Practice will improve
your skills in maneuvering on rough terrain.
•
A minimum of 20% of the tractor and equipment
weight must be on the tractor's front wheels.
Without this weight, the tractor could tip over,
causing personal injury or death. The weight
may be attained with a front-end loader, front
wheel weights, ballast in the tires or front tractor
weights. When attaining a minimum 20% of the
tractor and equipment weight on the front
wheels, you must not exceed the ROPS weight
certification. Weigh the tractor and equipment.
Do NOT guess or estimate!
•
Some Category 0 tractors have very short lift
arms or 5/8" diameter (Cat 0) lift arm ball ends.
These tractors are not usually suitable for using
the Heavy Duty Rotary Cut Mowers. Check with
your dealer on the Medium Duty Rotary Cut
Mowers that have the Category 1 hitch that fits
the Category 0 tractors.
•
This manual covers two types of Rotary Cut
Mowers - the Heavy Duty and Medium Duty
Mowers. The Heavy Duty Mower has a slip
clutch attached to the gearbox. The Medium
Duty and Sub Compact Mowers have a
shear bolt.
Slip Clutch Adjustment
(when unit is supplied with one)
The Slip Clutch is designed to slip so that the
gearbox and driveline are protected if the
mower strikes an obstruction.
A new slip clutch or one that has been in
storage over the winter may seize. Before
operating the mower, make sure it will slip by
performing the following:
1. Turn off tractor engine and remove key.
2. Remove driveline from tractor PTO.
3. Loosen the six 10mm cap screws to remove
all tension from the spring plate.
4. Hold clutch hub solid and turn shaft to
make sure clutch slips.
5. If clutch does not slip freely, dissemble and
clean the thrust plate faces, flange yoke,
and clutch hub.
6. Reassemble clutch.
7. Tighten spring until it is against the thrust
plate of the clutch and then back off each of
the six nuts by two full rotations. The gap
between the spring and thrust plate should
be 1/8".
8. If clutch continues to slip when the spring is
compressed to 1/8" gap, check friction
discs for excessive wear. Discs are 1/8"
when new. Replace discs after 1/16" wear.
Minimum disc thickness is 1/16".
Shear Bolt Replacement
1. Slide yoke shield back.
2. Realign holes in yolk and shaft and remove
shear bolt with hammer and punch.
3. Install new shear bolt. Lock yolk shield into
place. Use only genuine Behlen Country
replacement bolts.
