OPERATING INSTRUCTIONS

Brown TRENCHMASTER ®

BEFORE STARTING ENGINE

1. Check machine
a. Read and be familiar with equipment operating instructions.
b. Be sure you have the proper rotor for trench size and soil conditions.

(See equipping your TRENCHMASTER® for varying conditions, Page 6-1.)
c. Check rotor retaining nut for tightness. (See Assembly Instructions)
d. Be sure belts and pulleys are properly aligned and adjusted.
e. Check hood mounting bolts and nuts for tightness.
f. Check set screws in pulleys& lock collars for tightness.
g. Check all other nuts and bolts for tightness.
h. Check Clutch Cable tension. Tension is adjusted using the turnbuckle so that

the clutch spring stretches approximately 3/4” to 1” for 7” & 9” models or 1”

to 1-1/4” for 12 “ models when the clutch lever is completely engaged.
i. If your TRENCHMASTER® is equipped with a rock rotor, the points

must be loose and free to rotate. There should be 3/32” - 1/16” clearance

between nut and point socket. (See Illustration on page 3-3.)

2. Check machine

CAUTION:NEW ENGINES SHIPPED WITH MACHINES ARE

NOT SERVICED. ADD OIL TO CRANKCASE BEFORE STARTING.

WARNING:Gasoline is extremely flammable and highly explosive

under certain conditions. Always stop the engine and do not refill tank while

you are smoking or near open flame or sparks.

WARNING:Never start or run the engine while in an area where

fumes may collect. Carbon monoxide from the exhaust is an odor less and

deadly gas which must have adequate space or ventilation to allow rapid

dispersal.

a. Be familiar with manufacturer’s operating and safety instructions for engine.
b. Check oil level with dipstick and add if necessary. Do not overfill.
c. Check air filter and clean if necessary. Clean frequently if operating in dusty

conditions.
d. Use only clean fuel. Unleaded fuel is recommended in all engines.
e. Be sure muffler and exhaust deflector are installed, are in proper position,

and are in good operating condition. (Deflector should exhaust to left,

away from the air intake.)

3. Start engine
a. Be sure clutch lever is in disengaged position and no tension is on

drive belts.
b. Turn ignition switch to “ON” position.
c. Close choke if engine is cold.

3-1

Starting Engine Continued

d. Pull start cord rapidly.
e. When engine starts, gradually open choke and let engine warm up at about

1/4 speed.

WARNING:Do not operate machine without rotor hood installed

and secure.

WARNING:Do not operate the machine within a 50’ radius of people,

animals, automobiles or glassed areas which might be damaged by projectiles.

WARNING:Operator must wear eye protection when operating the

TRENCHMASTER®.

WARNING:Operator must locate and stay clear of all underground

gas, electric, water and communications lines before starting trenching
operation.

CALIFORNIA PROPOSITION 65 WARNING: Engine exhaust from this product

contains chemicals known to the State of California to cause cancer, birth
defects, or other reproductive harm.

4. Operation
a. T

o start trenching, set throttle full open. Before engaging the clutch lever,
the handle must be pushed toward the ground enough to allow the rotor to
turn without hitting the ground. When rotor attains operating speed, the
handle should be raised slowly so that the rotor engages the ground and
gradually digs to trench depth.

b. When trench depth is achieved, the operator should pull the machine to the rear

at such a speed that the trencher will dig without overloading the engine.

WARNING:Starting the trench is the most critical time for dangerous

flying projectiles. Be especially cautious by policing the area for rocks or
other possible projectiles and ensure the area is completely clear of people,
animals, vehicles, etc. that may be damaged by projectiles.

c. When trenching, if trencher strikes an underground object, stop

immediately to determine what the object is. Investigation should be done
visually since touching an exposed electric wire could be fatal.

d. When trencher strikes a rock either the trench or rock should be moved unless

your trencher is equipped with the rock rotor. If it has the rock rotor, then
proceed slowly with a constant pressure against the rock. If the rock doesn’t
begin to crush or move after a few seconds, it may be necessary to remove
the rock because the rock rotor can’t cut through rock requiring more than
10,000 P.S.I. to crush.

e. When digging in extremely hard clay or other difficult soils, it may sometimes

be necessary to use an oscillating action by applying and releasing pressure
on handlebar, front to rear, alternately.

3-2

OPERATING INSTRUCTIONS (CONTINUED)

NOTE: Use the smallest rotor possible when trenching in hard clay, rocky or other difficult soils.
Most cable TV or satellite dealers use a 4” or 5” deep rotor instead of the 7”. By using a smaller
rotor you may trench faster, you have less dirt to clean up and the rotors will last longer.

f. As a safety consideration, where the soil has a large content of gravel and small

rocks, it may be necessary to dig a hole by shovel to start the trench. This may
preclude property damage or an injury from flying debris. (This would apply when
near buildings or populated areas).

g. If you encounter an unusual vibration when trenching, stop and shut off the engine

immediately. Inspect to make sure that a point has not been broken. If a point is
missing or broken, replace the point if it is a rock rotor or replace the rotor if it is a
clay rotor.

h. When installing points on rock rotors, the points must be loose and free to rotate to

prevent uneven wear and breakage. The flat nut must go on first. When the flat
retaining nut is tightened to the end of the threads there should be a gap of 1/16” to
3/32” (thickness of a nickel) between the socket and the flat nut. Use two wrenches
to jam the lock nut against the flat retaining nut. See diagram below.

i. The diagram below provides guidance for positioning components when replacing spindle,

bearings or pulley on all models.

j. Bearing and/or Spindle replacement - To replace the spindle and bearings it is advisable to

remove the clay hood. Before loosening the lock collars you must remove the rotor
pulley.The pulley is cast iron and is easily broken if impacted on the outer edges.Use a
hammer and punch (or 3/4” bolt) against the thick center portion of the pulley. Soaking with
penetrating oil will help. When the pulley is removed, loosen the set screws on the lock
collars. Drive the shaft out from the pulley side. The back-up nut on the spindle is fixed and
should not be loosened. Each bearing seats against a shoulder in the housing. They must
be removed by placing a punch through the housing from the opposite side.

HOW TO INSTALL THE SELF-LOCKING COLLAR

The Self-Locking Collar originated in 1925. It was designed to facilitate the mounting of
wide inner ring ball bearings by eliminating the need for locknuts, washers, shoulders,
sleeves and adapters. This collar made the wide inner ring ball bearings easiest of all to
install. The inside of the locking collar has a counter-bored recess which is made eccentric
with the bore. The collar and the end of the bearing inner ring with which it engages are
both machined to act as mating cams on the shaft. When the collar is engaged to the
inner ring, it grips the shaft tightly with a positive binding action that increases with use.
No adjustments of any kind are necessary and it is impossible to cramp or overload the
bearing in mounting.

3-4

1. Observe cam design of wide inner

ring and self-locking collar. use the

punch in the unthreaded hole.

2. Mate cam of collar with cam of

bearing inner ring.

3. Pressing collar lightly against inner ring,

turn collar in direction of shaft rotation
until engaged.

4. With drift pin in collar hole, strike in

direction of shaft rotation to lock.

5. Tighten set screw in collar after applying

Locktite Threadlocker #242 to the set
screw threads.

SCHEDULED MAINTENANCE

Good maintenance practices are critical if you are to enjoy trouble free operation and long
life from your Brown TRENCHMASTER®. Most required maintenance procedures are
shown in this section. However, other common sense maintenance practices such as
cleanliness and storage must be followed.

1. See manufacturers operating and maintenance instructions for engine maintenance
procedures.

2. Check all bolts and nuts for tightness before operation and periodically thereafter.

3. Check all set screws in belt pulleys and bearing lock collars before operation and
periodically thereafter. If set screws are vibrating loose, Locktite’s “Threadlocker”
#242 should be applied to the threads and the set screws retightened.

4. Check drive belts for proper tension before operation. Adjust if necessary. Adjust belt
tension using the turnbuckle to ensure the spring stretches approximately 3/4” to 1” for
7” & 9 “ models or 1” to 1-1/4” for 12 “ models when clutch lever is engaged. Keep belt
free of dirt and grease at all times.

5. Rotor points must be checked for wear before operation and periodically thereafter.
Check at least every 200 feet initially. When working in difficult soil conditions, they
should be checked more often. In good soil conditions, they may be checked less
often but never less than each 500 feet of trenching.

6. Check rock rotors before operation and periodically thereafter. Points on the rock
rotors should be loose in the socket and should rotate freely to prevent uneven wear or
breakage. The nut on the point should have between 1/16” and 3/32” clearance (a
nickel is 1/16” thick) between the nut and the socket (See Figure on page 3-3)

7. Check rotor bearings for wear every 2000 feet. This is done by lifting the front of the
machine off the ground so that the rotor may be turned by hand. Then grasp the end
of the rotor firmly and try to move it from side to side. If there is more than 1/4” move­ment from side to side,the bearings must be replaced.

8. Check the idler pulley for wear before operation and replace if necessary.

9. Periodically check the idler arm for lateral movement. If the pivot bolt is badly worn, or
the bolt is loose, the idler arm may have enough lateral movement to cause the belts
to come off the pulley. The pivot bolt should be tight enough to prevent lateral move­ment, but not so tight that it restricts free pivoting of the idler arm.

10.See page 3-4 for instructions on how to use the eccentric lock collar on rotor bearings.

EQUIPPING YOUR TRENCHMASTER®

FOR VARYING CONDITIONS

There are several options available which enable you to adapt your TRENCHMASTER® to
perform well under varying conditions.

The most common conditions requiring special adaptation are listed below and recommended
options are listed with each condition.

1. Soil type
a. Sand, sandy loam, swampy & river soils - Use clay rotor.
b. Sticky clay or wet soils - Use clay rotor.
c. Rock, stone & heavy gravel - Use rock rotor.
d. Scattered rock, small gravel, asphalt and hard clay - Use clay rotor.

SPECIAL NOTE: Rock rotor points should not be used in sand. Sand may jam the points
and cause extremely rapid wear.

2. Soil moisture
a. Wet sand and damp abrasive type soils - Use the clay rotor.
b. Wet clay or wet heavy soils & any soil that is adhesive or cohesive - Use the

clay rotor.

3. Depth and width of trench
Choose the smallest trench that is practical for the job. Digging a smaller trench
will save you time and money in three ways:

a. You will be able to trench faster.
b. You will have less soil to clean up.
c. your digging rotors will last longer.

4. Root Pruning - Use root pruner rotors.

5. Selecting the proper rotor for your TRENCHMASTER® ( See the rotor compatibility list

on page 10-1)

ASSEMBLY INSTRUCTIONS DIAGRAM

For Models F-781H & F-991H

NOTE: Assembly only requires handle installation and connection of clutch cable.

1. Remove the 3 wing nuts from the belt guard and remove the cover.

2. Remove the rubber protective cover from the pivot bolt.

3. Place the handle down over the pivot bolt until it sits flat on the pivot brace.

4. Place the pivot brace plate over the pivot bolt on top of the handle.

5. Align the handle with the machine and secure the pivot brace plate to the frame using the
5/16” X 1” bolt, washer and locknut.

6. Lock the steering lock rod in the pivot brace plate and install the flat washer and the 1/2”

nylon lock nut on the pivot bolt.

7. Tighten the 1/2 nylon lock nut down completely and then loosen 1/4 turn.

8. Align the rear wheels and attach the steering connecting rod (already attached to the steering axle)

to the handle. The tie rod end must be under the connecting point on the handle. If necessary,
adjust the length of the steering connecting rod to insure proper tracking of the rear wheels. Unlock
the steering lock rod and turn the handle. If the lock rod doesn’t release and prevents the handle
from turning, you may need to adjust the lock rod catch on the upper part of the handle.

9. Pass the cable clevis through the sheave guard (mounted on the pivot brace plate) and attach to the

idler arm with a clevis pin and cotter key. Install the cable sheave in the sheave guard with a sheave
pin (clevis pin) through the upper holes (on top of the cable) and place another sheave pin through
the lower holes under the cable. Secure both sheave (clevis) pins with cotter keys. Attach the clutch
cable spring to the clutch lever. Adjust the tension on the control cable by shortening or lengthening
the turnbuckle attached to clutch spring. When properly adjusted, the spring should stretch about
3/4” to 1” when the clutch lever is closed. Be sure to tighten the jam nut on the turnbuckle once the
proper tension is set.

10. Replace the belt guard cover and secure it with the 3 wing nuts.

11. To install the rotor blade, remove the outside nut from the spindle (the inside nut is fixed to the

spindle). When looking under the hood, the rotor turns counter clockwise. Therefore, place the
rotor on the spindle with the points pointed up on the end of the rotor nearest the handle.
Replace the nut, securing the rotor on the spindle. This nut does not need to be put on extremely
tight. Tighten to about 100 foot pounds of torque or hand tighten with a 14” pipe wrench.
CAUTION!! If using an impact wrench, do not over tighten because it may be very difficult to
loosen the nut to change rotors.

NOTE: GREASE SHOULD NOT BE USED ON ANY STEERING PARTS. WE FEEL THERE WILL BE
MINIMUM WEAR BECAUSE THE MOVEMENT OF THE PARTS WILL BE LIMITED. GREASE WILL
ATTRACT DIRT WHICH ONLY INCREASES WEAR.
