SERVICE INFORMATION
1. Check reservoir level using sight glass on the left side of the tank. If required, add to reservoir tractor
transmission / hydraulic fluid. For machine use in ambient temperatures between +32°F (0°C) and
+90°F (32°C) hydraulic fluid ISO 68 is recommended. If the machine is operated at temperatures
below +32°F (0°C) then hydraulic fluid ISO 46 is recommended. Recheck oil level after the tiller
has been run and oil has been circulated through the wheel and tine motors. Routinely check
level thereafter. DO NOT OVERFILL THE TANK.
2. Change the hydraulic oil filter after the first 50 hours of use. Change it after every 200 hours
thereafter.
3. Add 1 quart of hydraulic oil to the reservoir with each oil filter change.
4. Check the tine bolts after each use and tighten as needed. Check all hydraulic fittings for
leaks and tighten if necessary.
5. Tines should be changed as often as needed for the machine to do a satisfactory and efficient
tilling job. Use Loctite stud and bearing adhesive/sealant on tine bolt threads to prevent
loosening.
6. The grease zerk on both ends of the tine shaft flange bearing should be greased after every 4
to 8 hours of use.
7. Grease zerks on the wheel hubs should be greased once a week or so, depending upon
freewheel use.
IMPORTANT: The engine is normally serviced prior to shipping. However, shipping
regulations may prohibit this. Check levels and add oil and fuel as required before starting.
Service according to the engine manual before starting.
IMPORTANT: If the couplers between the engine and the
pump are moved or removed for any reason, it is CRITICAL
that they have a 1/8” gap between them when reinstalled.
Failure to have this gap will result in rapid wear and failure of
your pump!
NOTE: It is very important to move the fuel shutoff lever to the closed position after
stopping the engine. Failure to do so could cause fuel to leak down into the cylinder and
crankcase. Damage resulting from this will void your engine warranty and not be covered.
WARNING: Running the tiller without hydraulic oil will cause serious damage to the hydraulic
pump. CHECK RESERVOIR LEVEL BEFORE STARTING THE MACHINE.

916/918 TILLER TROUBLE SHOOTING GUIDE
CAUTION: ALWAYS USE EXTREME CARE WHEN TROUBLE SHOOTING OR MAKING
ADJUSTMENTS ON THE TILLER. STAY CLEAR OF TINES WHEN ENGINE IS
RUNNING. ALWAYS SHUT THE ENGINE OFF BEFORE DISASSEMBLING ANY
COMPONENT.
A. ENTIRE HYDRAULIC SYSTEM DOES NOT OPERATE AND THE ENGINE IS NOT
UNDER LOAD
1. Broken or improperly adjusted clutch
(actuator) cable.
If broken, replace. Remove slack then
adjust for 7/16” to 1/2" movement at
actuator lever pin.
2. Low hydraulic oil in tank.
Fill to center of sight glass.
3. Hydraulic pump-to-engine coupler has
slipped.
Check for wear and replace both coupler
halves and rubber spider as needed.
4. Hydraulic pump worn or tine motor relief
valve not functioning properly.
Follow the series of tests described below:
Remove the tank end of hose that goes from the pump to the tank. Start the engine and with the
tines and wheels in neutral, pump off about four gallons of hydraulic oil into a clean bucket.
(The .52 CID pump, @ 1000 PSI & 3000 RPM, should pump at the rate of 6.5 GPM.) Replace
the hose and remove the tank lid. Remove the end of the intake hose from the fitting on the tank
lid. Submerse the end of the hose in the hydraulic oil in the tank. (A non-collapsible hose
extension may be required.) Block the tines with a short 4 X 4 and stand to the side.
With tines selected to forward rotation, activate the actuator valve and check to see where the oil
enters the tank. If the pump is good, the oil will enter through the relief valve or the return line
from the filter. If the oil returns only through the filter return, the tine-drive motor is bad.
If the oil returns through the relief valve but does not kill the engine, check the out-put pressure
of the pump. To do this, "T" a 4000 pound gauge into the line at the tank. DO NOT BLOCK
THE LINE OR DEAD-HEAD THE GAUGE INTO THE LINE. With the tines in forward and
blocked, activate the hydraulic valve as before. The relief valve is set at 2750 pounds. If the
gauge reaches this pressure, the valve is OK. If not, the relief valve is bad and needs to be
replaced.
If the pressure reaches 2750 pounds but there is only a small amount of oil returning, the pump is
worn and should be replaced.

TROUBLE SHOOTING GUIDE (continued)
B. TINES FAIL TO ROTATE BUT WHEELS DRIVE.
1. Clutch cable stretched so needs
adjustment
Remove cable slack then adjust for 7/16” to
1/2" movement at actuator lever pin.
2. Tine motor worn.
Rebuild or replace motor. New motors are
available from Barreto Manufacturing, Inc.
C. WHEELS FAIL TO TURN BUT TINES ROTATE
1. Wheel axle keys have been sheared or
removed.
Replace keys.
2. Wheel relief valve bad
Replace relief valve.
D. ENGINE LUGS DOWN OR DIES AND WHEELS AND TINES DO NOT TURN.
1. Rocks or other obstruction blocking tines.
Shut OFF engine and remove obstruction.
2. Tine shaft bound with wire, vines, or
grass.
Shut OFF engine and remove debris,
especially at the ends.
3. Tilling depth too great for soil conditions.
Shut OFF engine and lower depth bar to
raise the tines, decreasing tilling depth.
4. Outboard tine shaft bearings binding.
Lubricate or replace bearings as needed.
5. Engine improperly tuned or maintained.
See engine manual and correct as needed.
6. Low oil alert causes engine to shut down.
This may occur if tilling on hills, (not
advised). Level the tiller and check engine
oil level. Fill if required. Oil alert should
reset. See engine manual.
7. Engine losing power due to wear.
See engine manual.

OPERATING INSTRUCTIONS
1. READ SAFETY INSTRUCTIONS BEFORE OPERATING!
2. Be sure engine oil and hydraulic oil are at proper levels before starting the tiller.
3. STUDY AND UNDERSTAND CONTROLS BEFORE BEGINNING
OPERATION!
4. NEVER RUN THE MACHINE IN REVERSE WHILE TINES ARE ROTATING!
5. Always move the tine control lever to "OFF" before reversing wheels.
6. The TINE DRIVE lever should be set at "OFF" when moving the tiller from place to
place while not tilling.
7. CLUTCH (ACTUATOR) LEVER: (At left handle grip) Activates the wheel drive and
tine rotation controls when squeezed. When released, all motion stops.
8. WHEEL DRIVE LEVER: The wheel speed is variable both in forward and reverse.
Moving the WHEEL DRIVE lever to the right causes the tiller to go forward; moving
to the left to back up. The farther the control lever is moved away from center, the
faster the tiller will travel. When the lever is centered, the wheels are locked in a
neutral or park position.
9. TINE DRIVE LEVER: The tines operate at a constant speed. The TINE DRIVE
lever must be moved all the way over to either the forward "ON" position or “REV”
position when tilling. If an object becomes lodged in the tines, put the WHEEL
DRIVE lever in neutral and change direction of the tines to dislodge it.
10. OPERATE TILLER ON LEVEL GROUND ONLY!
11. TILLING OPERATION: In most soil and sod conditions, the depth bar can be set
with the pin in the third hole from the top. When starting to till, move the TINE
DRIVE lever to the ON (forward) or REV position. Tines will dig in either the
forward or reverse rotating direction. Squeeze the CLUTCH LEVER completely to
engage the tines. Move the WHEEL DRIVE lever to the right until the desired
wheel speed is reached. Under most conditions, at least two passes must be made.
For deeper tillage, move the depth bar up one hole at a time.

DETERMINE LOCATION OF UNDERGROUND UTILITIES
OSHA CFR 29 1926.651 requires that the estimated location of underground utilities be determined before
beginning excavation or an underground drilling operation. When the actual excavation or bore approaches
an estimated utility location, the exact location of the underground installation must be determined by a
safe, acceptable and dependable method. If any utility cannot be precisely located, the appropriate utility
company must shut it off.
Call before you dig. If you do not call, you may cause an accident; suffer injuries or death; cause
interruption of services; damage the environment; and/or incur project delays. Expect to be held liable for
any damages caused, if you fail to call.
DANGER: Buried electric cables or gas lines can cause serious injury or death if struck with tiller
tines. Always determine location of utilities before tilling.
WARNING: Fiber optic cables convey laser light that can injure your eyesight.
CALL 1-888-258-0808 TO LOCATE UTILITIES BEFORE TILLING (US. OR CANADA). This free
service will provide a “One-Call” number for the geographic area that you select. Before you start any
digging project, be sure to call the local One-Call system in your area and any utility company that does
not subscribe to the One-Call system. The One-Call representative will notify participating utility
companies of your proposed digging activities. Utilities will then mark their underground facilities by
using the following international marking codes:
Red
Yellow
Orange
Blue
Green/brown
White
Pink
Electric
Gas, oil, or petroleum
Communication, telephone, television
Potable water
Sewer

WORK SITE ASSESSMENT
Examine the work area for any conditions or obstructions that may inhibit tilling or create a safety hazard
for the operator or others. Use the information in this manual combined with good judgment to identify any
hazards to avoid.
In addition to calling to DETERMINE LOCATION OF UNDERGROUND UTILITIES (see previous
section for details), the operator and/or job foreman should visually inspect the work site. Look for
electrical drop boxes, notices of underground placements, manhole covers, recent trenching or tilling
activity, any evidence of possible underground placements, banks, drop-offs, rocks, wire, uneven terrain,
any existing holes and toxic ground conditions.
Only operate tiller outdoors and avoid breathing engine exhaust and fumes.
WARNING: Engine exhaust contains carbon monoxide gas that is toxic. Breathing it can cause
unconsciousness and death.
Do not operate tiller near any source of flammable dust or vapors.
WARNING: Sparks from the engine exhaust can cause an explosion or fire in a flammable or
explosive atmosphere. Fuel fumes can catch fire or explode.
Allow adequate side and overhead clearances between tiller and any objects such as buildings,
fences, and trees.
Adequate lighting is required, daylight or artificial, for safe operation of the tiller.
Keep others away. If the job site is near a road or pedestrian path, warn and divert both motorized
traffic and pedestrians. As appropriate, erect barriers, use traffic flag personnel, signs, cones, and
lighting devices to insure safety.
WARNING: Someone could step into the tilled area by accident. Walking near the edge of the
tilled area could cause loss of balance and possibly cause someone to fall into the rotating tines.
Contact with the rotating tines while in operation will cause serious injury or even death.
MACHINE FUNCTION CHECK: If the operator releases the CLUTCH LEVER, the wheel drive and
rotating tines should stop. This is intended for your safety and must be maintained in good functional
condition. Contact your dealer or the factory if anything on the tiller does not function properly.

CONTACT WITH UNDERGROUND UTILITIES
After LOCATING UNDERGROUND UTILITIES and performing the WORK SITE ASSESSMENT,
accidental tine contact with a buried utility might still occur. If it does, stop tilling and call 911 for help.
If you cut a wire or cable, assume that you do not know what kind it is. It may be electrical or any one of
several communication lines: telephone, television, or fiber optic. In any case, do not touch it or even look
at the ends of it. Stop tilling and call 911 for help. Do not till any more until the appropriate utility
company has assessed the situation, taken appropriate action, and informed you that is safe to proceed.
If you strike a pipe, it could be gas, oil, petroleum, water or sewer. In any case, stop tilling, shut off the
engine, and evacuate the area immediately. Call 911 for help.
Electrical wires or cables: If you think that you may have severed electrical wires, stop tilling and call
911 for help. Keep yourself and other people away from the area.
DANGER: An electric shock could kill you. Assume that any severed wire or cable is HOT with
voltage and do not touch it!
Gas lines: If you think that you may have struck a gas line, shut off the engine and evacuate the area
immediately. Call 911 for help.
DANGER: A gas explosion could kill you. Sparks will likely occur from the tines scraping the
metal pipe. If gas leaks out an explosion could easily occur.
Fiber optic cables: If you think that you may have severed a fiber optic cable, do not touch or even look at
the ends of it.
WARNING: Fiber optic cables convey laser light that can injure your eyesight. Call 911 for help.
