WARRANTY NOTES
•All parts returned to Brown Manufacturing Corp. for warranty inspection must be received freight
prepaid.
*All Warranty Work MUST be approved by Brown Mfg. Corp. BEFORE work begins.
•If a warranty claim is approved, replacement or repaired parts will be returned to the customer freight
prepaid.
•If a dealer makes any type of approved warranty repair, only parts and labor will be credited by Brown
Manufacturing Corp. No service call or transportation charges are warrantable.
•No returned parts will be inspected for warranty claims if not received with a Return Authorization
Number. Without a RMA#, Brown Manufacturing Corp. cannot and will not be responsible for
any returned goods.
•Drive shaft / slip clutch warranties: Many factors can cause a slip clutch to fail. Most failures are not

WARNING: The use of after-market replacement parts will change the operational conditions of
the machine, shorten the life of other components, lead to failure of the machine, and create safety
hazards to all persons near the machine. Brown equipment is designed to use original manufacturer
replacement parts meeting the exact specications of the machine and crafted from high-quality materials.
After-market replacement parts are neither engineered to meet the machine’s exact specications nor
manufactured to the same high standards as original Brown replacement parts.

Exercise caution
while working under
cutter deck. Failure
to heed warnings
may lead to serious

Equipment Safety
Using Choke Chains (Optional) - Not a factory
supplied option.
Choke chains are lengths of chain that attach from the tractor
ROPS to the lift pins of the cutter unit. The chains are
intended to hold the weight of the unit, insuring that the front
of the cutter remains at a xed alti tude above the ground and
removing the weight of the unit from the tractor’s lift arms.
Choke chains attach to the outside of the cutter unit’s lift pins,
after the tractor’s lift arms have been properly attached to the
unit. The chains’ hitch plates are then se cured in place by the
existing spring-clip pins in the unit’s lift pins.
The chain system consists of two lengths of suitable chain,
each with one end terminating in a hitch plate. A bracket
attached to each side of the tractor’s ROPS holds the other ends
of the choke chains taut in slots milled to the width of a chain
link. Choke chain length is adjustable by choosing which chain
link is inserted into the retention slots of the ROPS brackets;
ne-tuning of the chain lengths may be performed by twisting
the chains before securing the chains into their retention slots
on the ROPS brackets.

Assembly
16
1. Install tailwheel stem into fork holder tube, placing collar over stem and inserting roll key
through collar and stem.
2. Raise A-frame from its shipping position to its operational position (almost perpendicular to
the cutter deck). Remove bolt holding Flex-link toggle to the A-frame. Install A-frame braces
to outside surface of A-frame and replace bolt. Note: keep top toggle in position when
reinstalling A-frame bolt.
3. Bolt the rear end of the A-frame brace to the mounting bracket near the read or the machine deck.
4. Tighten all bolts securely.

17
Assembly
4. Separate the male and female halves of the drive shaft. Apply heavy grease to the telescoping
portion of the male drive shaft; recouple the drive shaft.
5. Locate the slip clutch bell shield, clamp, and mounting plate attached to the machine. Remove
the mounting bolts, at washers, and lock washers from the gearbox face plate. Position the bell
shield mounting plate (at side up) over the input shaft and align it with the threaded holes in the
gearbox face plate. Secure with bolts, at washers, and lock washers previously removed.
Warning
The driveline shield and bell shield must be kept in good operating condition. Failure to maintain
safety shields can result in injury or death.
7. Remove both lock bolts from the clutch hub assembly. Slide the hub onto the input shaft of the
gearbox. Align the groove on the input shaft with the bolt holes in the hub. Reinstall the lock
bolts and tighten securely. Retorque lock bolts every hour for the rst eight hours of use.
Failure to do so will result in decreased life of the clutch hub and gearbox shaft splines.
8. Check the drive shaft for proper length:
a. Hitch the cutter to the tractor.
b. Lift the cutter to the tractor’s maximum lift position.
c. Measure the distance from PTO of the tractor to the input shaft of the cutter’s gearbox.
d. Push both halves of the drive shaft together fully. Measure the overall length.
e. If the length of the compressed drive shaft is greater than the length between the PTO and
input shaft, then the drive shaft must be shortened.
Please note that equal amounts must be removed from each section of the drive shaft.

Operation
18
Before hitching cutter to your tractor, make sure all safety devices are installed on both the cutter and
the tractor.
Please follow all safety instructions and procedures.
Attach equipment to tractor.
Be sure the tractor is equipped with the correct category hitch pins, top link, etc.
Be extremely careful when positioning tractor to hitch to the equipment.
Caution Never allow anyone between the tractor and the equipment during the hitching
process.
Be certain that the cutter has been lubricated properly and check oil level in gear box prior to connecting
driveline to tractor. Also, do not tighten the top link such that the ex-link toggle is fully extended
toward the tractor. The ex-link should be in a relaxed position when on level ground. See
Illustration 19-1.
Attach the driveline to the tractor. When attaching driveline to PTO shaft, be certain that the
quick-disconnect pin is properly seated.
Warning A loose driveline can disconnect and cause personal injury or property damage.
Adjust cutting height.
Warning Be certain that tractor engine is stopped, key is removed, and all rotation of the
cutter has ceased before making adjustments.
CautionAvoid very low cutting heights. Striking the ground with blades causes a damaging
shock that can damage both the cutter and the tractor.
Using the tailwheel adjustment and the tractor’s lift arms, set the cutter to the desired height;
the cutter is designed to operate with a cutting height range between 2” and 12”.
Note that, on level ground, the front of the cutter should be 1” below the rear (see
illustration). Set the tractor’s lift stop at the required position to maintain a uniform cut.
STOP
1” above front
Front

Starting Cutter
Power for operating the cutter is supplied from the tractor PTO. Refer to your tractor manual for
instructions on engaging and disengaging the PTO.
Warning Do not operate this cutter unless the tractor has a live, or independent, PTO.
The momentum created by the blade carrier can push the tractor forward unexpectedly.
Warning Operate cutter only with the specied PTO RPM. Brown 672 Model cutters are
designed to operate at 540 RPM; however, a 1000 RPM design is an option.
Operating speed
Proper operating speed for equipment will depend upon the height, density, and type of the material
to be cut. Regardless of chosen ground speed, always operate the PTO at the recommended RPM
when cutting.
General Operation
Warning The cutter creates a very serious discharge hazard.
Maintain a safe distance from nearby persons and property. Do not
operate when bystanders are present.
Warning Avoid personal injury. Remove all rocks and
other debris from work area before cutting.
Observe the following guidelines when operating the cutter:
• Never lower the cutter onto material.
• Avoid tight turns near trees or stationary objects. The deck may be damaged by side impact.
Remember: The safe operation of this equipment is the responsibility of the operator. The operator
should be familiar with both the tractor and the equipment. He must read and understand all
applicable operator manuals and follow all safety practices.
