SAFETY WEAR
Never wear loose clothing or jewelry that can be caught by moving parts of your stump cutter and
pull you into it. Keep all clothing away from moving parts. Wear proper headgear to keep hair
away from moving parts.
Always wear safety glasses provided with your unit at all times while operating your stump
cutter. A chip could fly out and hit you in the eye. Be sure your glasses fit properly.
SAFETY OPERATING PROCEDURE
If it is necessary for any reason to inspect or repair any part of the machine, stop the machine, allow it to cool,
disconnect the spark plug wire from the spark plug and move it away from the spark plug before attempting
such inspection or repair. Whenever you operate your stump cutter, wearing safety glasses is required.
Before each use, check all three controls; brake, throttle, clutch, to be sure they are functioning properly.
The operation of any stump cutter can result in foreign objects being thrown into the eyes, which can result in
severe eye damage. Always wear the safety glasses provided with the stump cutter or eye shields before
chipping or while performing any adjustments or repairs.
OPERATE IN A SAFE ENVIRONMENT
Operate equipment only in daylight or in good artificial light.
Extreme care must be taken when operating your machine on a side hill. It could tip, or poor footing could
cause an accident. Do not operate the machine parallel to the hill. Always stand uphill from the stump.
A. Secure handle in front or rear position.
B. Do not use your machine on muddy or icy surfaces.
C. Never leave your machine unattended with the engine running.
Thoroughly inspect and clear work area of objects that might be picked up and thrown. Remove all stones,
sticks, wires, bones and other foreign objects. Beware of hidden objects located above or below ground, such
as electric wires, gas or water lines, and sprinkler systems. DO NOT BEGIN TO CHIP STUMPS unless you are
sure the area is clear.
1. Know how to turn the machine off.
2. HANDLE GASOLINE WITH CARE as it is an extremely flammable fuel.
3. Check the fuel before starting the engine. Do not fill the fuel tank indoors, while the engine is running, or
while the engine is still hot. Turn the unit off and let the engine cool for at least three minutes before
refueling. Fuel your stump cutter in a clean area to avoid getting dirt in the gas tank. Do not smoke while
refueling. Fuel tankcap must be secure at all times except during refueling. Avoid spilling gasoline or oil.
Wipe the unit clean of any spilled fuel or oil.
4. Store fuel and oil in approved containers, away from heat or open flame, and out of reach of children.
Leave 1/2-inch air space at top of fuel tank to allow for expansion of fuel.
REPAIR AND MAINTENANCE SAFETY
Never operate your stump cutter in poor mechanical condition. Periodically check that all nuts,
bolts, screws, and belts are tightened to specifications. Be sure all safety guards and shields are
in proper position. These safety devices are for your protection.
Be sure to read and follow engine owner’s manual for engine maintenance and repair.

4 EA – CABLE TIES
STEP 1 - UNPACKING AND CHECKING CONTENTS
1. Remove all pieces from the skid.
2. Compare all items with the list above.
3. If any parts appear missing or damaged, contact Country Home Products at 1-800-376-9637.
4. Assembly should be done on a clean and level surface.
STEP 2 - INSTALLING HANDLE SUPPORT
1. Loosen and remove the two bolts mounting the handle support (item #23, pg. 15) to the bumper straps (item
#22, pg. 15).
2. Flip the handle support to the upright position with the six adjustment holes above the bumper straps.
3. Replace and tighten the bolts through the bumper straps to the handle support that were removed in step 1
STEP 3 - INSTALLING HANDLE ASSEMBLY
The handle assembly is packed with the cables attached, so be careful not to over extend the handle away from
the stump grinder and break them loose.
1. Remove bolt and nut (items #50 & #64, pg. 15) from the pivot pin weldment (item #13, pg. 15) and pull it out
of the pivot bracket.
2. Carefully pick up the handle assembly (item #14, pg. 15) and put it in place so that the bend is down and the
handle grips are at the cutter head end (rear position). NOTE: Care needs to be taken to prevent the cables from being torn loose, dislodged, or pinched.
3. Insert pivot pin through the first hole on the handle mount plate (item #9, pg. 15), through the lower handle
tube, and into the other hole on the handle mount plate.
4. Secure the pivot pin with the hardware you removed in step 1.

STEP 4 - SECURING THE CABLES
1. Four cable ties have been provided for fastening the cables to the handlebar after it has been installed.
Refer to figure 2 for the correct mounting points of the cable ties.
2. Attach the clutch cable in the center of the handlebar mounting pivot at point #1. Loop the cable so it
provides plenty of clearance from the belt guard and does not bind when the handle is rotated to the front
position. This attachment also keeps the cable away from the idler pulley.
3. With the handle in the rear position, opposite the cutter head, install the other cable ties at points 2, 3 and 4
(fig. 2).
4. Swing the handles from the front to the rear position while checking to make sure the cables do not bind or
become kinked.

REFER TO THE ENGINE OWNER’S MANUAL.
THE ENGINE ON YOUR STUMP GRINDER HAS BEEN SHIPPED DRY.
BE SURE TO SERVICE THE ENGINE ACCORDING TO THE
ENGINE OWNER’S MANUAL PRIOR TO STARTING.
FAILURE TO DO SO CAN RESULT IN DAMAGE NOT WARRANTIED BY
THE ENGINE MANUFACTUROR.
WARNING: Do not fill closer than ½” from the top of the fuel tank to prevent spills and to allow for fuel
expansion. If gasoline is accidentally spilled, move the mower away from the area of the spill. Avoid creating
any source of ignition until gasoline vapors have disappeared.
CAUTION: Experience indicates that alcohol blended fuels (gasohol, ethanol, methanol) can attract moisture
which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system or an
entire engine while in storage. To avoid engine problems, the fuel system should be empty before storage for
periods over 30 days. For more information, refer to the engine owner’s manual. Use fresh fuel each season.
Never use engine or carburetor cleaner products in the fuel tank or permanent damage may result.
ALWAYS CHECK OIL LEVEL PRIOR TO STARTING
THE STUMP GRINDER.

SECTION IV-OPERATION
These operating instructions are designed to help you get the most out of your stump cutter.
1. It is suggested that tall stumps always be cut to near ground level with a chain saw prior to cutting with this
machine. This is a big time saver.
2. Use a mattock or other digging tool to remove dirt and stones from around the stump as deep as you intend
to cut. This is important to prolong the life of the cutter teeth. Stones that are solidly embedded in the
stump and can’t be seen will only dull the cutting teeth. The loose stones should be removed since they
can chip a tooth or be thrown by the cutter head. Your cutter head is affixed with teeth of a mining grade
tungsten carbide. It will continue to cut in spite of stones, but the fewer stones it strikes-the better.
3. Select the desired handle location for the job. Remove the hair cotter and the clevis pin (items #78, #79, pg.
15). Swing the handle (item #14, pg. 15) over to convert the stump cutter to a front or rear cutter. If the
stump is close to a building or fence, have the cutter head in front. If the stump is in the open, you may find
it is easier to chip with the cutter head in the rear. You can also change the height of the handles by
positioning the clevis pin in one of several locations. Always secure the clevis pin with the hair cotter pins.
(Figure 3 pg. 6).
NOTE: Front Position
head.
Rear Position
4. If the ground is very soft, place a sheet of plywood around the stump, especially on the sides. Pull or push
the machine up onto the stump so that about 1/3 (3” or 4”) of the cutter head is nearly touching the stump.
5. Once the machine is positioned over the stump, squeeze the brake handle to lock the wheel. The brake
locks one wheel only and allows you to make a sweeping motion with the cutter head. You can hold the
brake on with one hand or lock it in position by depressing the brake handle lock (item C, Figure 6). To
unlock the brake, simply squeeze the lever and release.

1. Move kickstand to mid-position for rear-cutting and top position for front cutting. While not in use, move the
kickstand to the down position. This keeps the cutter head off the ground, preventing damage to the cutter
teeth.
NOTE: Never adjust the kickstand while the cutter head is in motion.
1. Move throttle control to the run position. The engine will stall if you engage the cutter head while the engine
is in idle.
2. Hold operator presence handle down against the rest of handle. This will engage the cutter head. When
the operator presence handle is released, the cutter head will stop in less than two seconds. Test the unit
before operating to make sure the clutch is performing properly. If the clutch does not perform properly
discontinue use immediately.
fig. 7
1. Start to cut the stump at the extreme left (rear position) or extreme right (front position). Swing the cutter
head across the stump, cutting approximately 2” of wood at each pass. As you become more familiar with
your machine, you will be able to cut left to right and right to left. The hardness of the wood and the
sharpness of the teeth will dictate how deep and how fast you cut. See figure 8.
fig. 8
1. At the end of each pass, allow the engine to recover to full speed. Release the brake to push or pull the
cutter further into the stump, re-lock the brake and continue cutting.
2. Continue to cut across the stump until entire stump is at ground level. To cut below ground level, position
cutter head in the center of the stump and work towards the outer edges.
9
HELPFUL HINTS
1. Chips are contained by the rubber guards and may begin to build up between the wheels.
Should there be excessive build-up, release throttle and move unit out of position and rake or
shovel away the chip build-up. A power blower or vacuum works well.
2. On larger stumps, if you continue to cut from one location, eventually a wheel may want to roll
into the hole. Before this happens, move to a different side of the stump to continue cutting.
3. It is a good idea to never operate the machine with the engine more than 30 degrees from
horizontal. This could cause engine damage due to lack of lubrication. This problem could
happen when a stump is on a steep hill. Try to cut the stump with the least amount of tilt.
WARNING
If the cutting head strikes a rock or curb and starts making an unusual noise or vibrating excessively:
1. Stop the engine immediately.
2. Disconnect the spark plug wire from the spark plug.
3. Allow the engine to cool.
4. Inspect for obvious damage.
5. Check for loose parts and tighten to assure continued safe operation.
6. Replace or repair any damaged parts.

SECTION V - MAINTENANCE
LUBRICATION OF THE ENGINE
Check engine oil level regularly-WHILE THE UNIT IS IN A LEVEL POSITION. Check the oil every five hours of
operation and before each usage. Stop engine and wait several minutes before checking oil level. With engine
level:
1. Remove the oil filler plug and check oil level. It should be to the top of the fill plug.
2. If the level is low, fill to the top of the fill plug.
Change oil after the first five hours of operation and every 25 hours thereafter. Refer to the engine manual
enclosed with this unit for additional information on your engine.
AIR CLEANER
Refer to the engine manual for additional information on the air filter
1. Do not operate engine if air cleaner or cover directly over carburetor air intake is removed. Removal of
such parts could create a fire hazard.
2. Do not use flammable solutions to clean the air filter.
BEARINGS
Grease cutter head bearings after every use. Greasing should be done after unit has been washed down as
water pressure can remove grease from the bearings. The greasing process will remove any water that has
penetrated the bearing. Lubricate bearings with a #2 lithium based grease while manually rotating cutter head
until fresh clean grease is seen purging from the bearing seals.
BELT TENSION
Check belt tension frequently. This is especially important in the first one hour of use. Once the belt is “seated”
and initially stretched (approximately two hours), recheck the tension. You should check the tension each time
you use the machine. To test belt tension, push down on the belt at mid span with moderate pressure. The belt
should move approximately 1/2”.
To adjust belt tension:
1. Loosen the four motor bolts
2. Tighten or loosen the adjustment nut on the belt tensioner (item #36, pg. 15) until desired belt
tension is reached.
3. Retighten the four motor bolts.
CALIPER BRAKES
The brake is needed to prevent the machine from moving away from the stump during cutting. To adjust the
brake:
1. Loosen the locking nut on the brake handle. (Item B, fig. 9)
2. Turn the brake adjuster (Item A, fig. 9) out, away from the handle, a few turns.
3. Continue to check to see if the brake is holding.
4. When the brake “holds”, the correct adjustment is reached. Re-tighten the locking nut. (Item B, fig. 9).
fig. 9
11
1. If correct adjustment cannot be achieved at the handle, turn the brake adjuster all the way in and adjust
brake tension at the brake caliper.
2. To adjust brake at caliper (item #26, pg. 15), loosen locking nut (Item B, fig. 10). Turn adjusting screw (Item
A, fig. 10) in until brake is holding. Retighten locking nut (Item B, fig. 10).
fig. 10
CLUTCH ADJUSTMENT
Your Stump Grinder is equipped with a brake clutch that controls the motion of the cutter head. When engaged
the clutch allows the cutter head to spin, when disengaged the clutch will stop the cutter head in under 2
seconds. It is critical that the clutch control cable be adjusted properly.
To adjust the clutch control cable:
1. Remove belt guard and disconnect clutch control cable from spring attached to clutch engagement lever
(item C, fig. 11).
2. With engagement lever fully forward measure 1 ½ “ backwards from the left hand edge of the lever and
make a mark on the clutch housing.
3. Re-connect the clutch control cable and adjust the jam nuts (item A, fig. 11) forwards or backwards as
necessary so that the lever does not pull backwards.
4. Compress the operator presence handle and check that left hand edge on the engagement lever moves
to the mark on the clutch housing.
5. Adjust cable accordingly if lever moves to the left or right of the mark.
6. If more adjustment is needed, move the cable end support (item B, fig. 11) as necessary.
Clutch cable tension should be checked periodically along with belt tension.
fig. 11
CLUTCH SERVICING
The clutch is shipped from the factory assembled and adjusted. No internal adjustment is available to the end
user. For service, return the clutch to the factory.
STORAGE
Never store your stump grinder indoors or in an enclosed, poorly ventilated area if gasoline remains in the tank.
Fumes may reach an open flame, spark or pilot light from a furnace, water heater, clothes dryer, cigarette, etc.
When not in use, your machine should be stored out of reach of children with the spark plug removed. Always
allow the engine to cool before storing of covering. For long periods of storage (over winter), please refer to the
engine owner’s manual.
12
SECTION VI – CUTTER HEAD
The cutter head is fastened to the mounting flange on the spindle with four 3/8-16 x 1-3/4” bolts. Be sure to
check them frequently for tightness. (Figure 12)
TEETH
Your stump cutter is equipped with carbide tipped teeth. (Items 24d, 24e, 24f, pg. 15) Carbide retains its
sharpness longer, cuts faster and smoother and can withstand heat, but they will wear. Sharpen the teeth
before excessive wear or when they look dull or rounded. Check the teeth on the cutter head after each use.
Always check the 45-degree tooth first because it is the most abused being a “digger and leader”. Any cutter
tooth with less than a 10-degree relief (see fig. 15, pg. 14) will cause poor performance, smoke and burn marks.
By keeping the teeth sharp, you will prevent frustration at the job site. It only takes a few minutes to touch them
up before you go out on a job. If the unit receives heavy use, a second cutter head assembly can be purchased
as a back up while the other head is being sharpened.
fig. 12 fig. 13
FOR PROPER OPERATION:
1. Teeth should be installed according to the pattern shown in Figure 13 above.
2. Cutter head must never be run with a missing or damaged tooth.
CAUTION: Excessive vibration is usually a result of broken or missing teeth. Stop engine, disconnect spark
plug wire and inspect.
TO SHARPEN
Teeth can be removed and sharpened individually or while still attached to the cutter head.
1. Remove entire cutter head (see figure 12) by removing the four 3/8”-16 nuts and bolts.
2. To remove the teeth from the cutter head, remove the 9 cap screws using the 5/16” Allen wrench
provided.
3. Tap any of the 9 teeth with a soft hammer to “pop” the cover off the cutter body.
4. Remove the 9 teeth from their slots.
WARNING: WHEN SHARPENING TEETH, ALWAYS WEAR EYE PROTECTORS AND A
DUST MASK OR RESPIRATOR. CARBIDE DUST CAN BE DANGEROUS IF INHALED.
13
5. Any bench-type or pedestal style grinder with a “Green wheel” (silicon carbide grinding wheel or
diamond wheel) may be used on the carbide teeth. A regular gray wheel (coarse grinding wheel) is
needed for grinding the steel relief. It is best if you can set up the grinder with a coarse wheel on one
side and “Green Wheel” on the other side.
6. Teeth may be ground free hand since precision is not important. Any variance between teeth will not be
noticed.
7. Using the “Green Wheel”, grind the end of the carbide until the edge is sharp. Avoid grinding on the
face of the carbide, which would reduce its thickness and weaken it, making it more susceptible to
cracking and chipping. (Figure 14)
fig. 14
8. As the end of the carbide is ground away, you will have to grind “relief” on the square steel shank. The
steel must be ground with the regular coarse grinding wheel and not the “Green Wheel”.
9. Although the angle is not critical, always grind the tooth so that there is enough “relief” under the
carbide edge (minimum 10 degrees). (Figure 15)
fig. 15
10. The tooth may continue to be ground until the carbide has approximately 1/4” remaining (Figure 16).
fig. 16
11. Before reinstalling the teeth, wire brush the inside of the cutter body and the cap screws. Spray with
light oil or WD40 and reassemble. Remember to reassemble teeth in the same order: 45 degree offset,
25 degree offset, and straight; repeated three times (Figure 13, pg. 13). Make sure to align the notch in
the teeth with the slot in the cutter head body so the cover plate can be assembled properly.
12. Torque cap screws on cover plate (item #24c, pg. 15) to 25 ft. lb. the first time around to insure even
pressure on the teeth. Alternate tightening screws in a crisscross pattern. Final tighten to 45 ft. lb.
13. The teeth can also be sharpened without removing them from the cutter head. Sharpen them free hand
by holding the entire head up to the grinding wheels.
14. To reassemble cutter head to drive shaft weldment:
15. Clean mating surfaces of cutter head and shaft. Spray both with light oil or WD40.
16. Reinstall cutter head using new 3/8” split lock washer and nuts
17. Pre-tighten nuts in crisscross pattern to 25 ft. lb. Final tighten to 45 ft. lb.
