General Hazard Information
No accident-prevention program can be successful without the wholehearted cooperation of
the person who is directly responsible for the operation of the equipment.
A large number of accidents can be prevented only by the operator anticipating the result
before the accident is caused and doing something about it. No power-driven equipment,
whether it be transportation or processing, whether it be on the highway, in the field, or in
the industrial plant, can be safer than the person who is at the controls. If accidents are
to be prevented--and they can be prevented--it will be done by the operators who accept
the full measure of their responsibility.
It is true that the designer, the manufacturer, and the safety engineer can help; and they will
help, but their combined efforts can be wiped out by a single careless act of the operator.
It is said that, “the best kind of a safety device is a careful operator.” We, at Unverferth
Mfg. Co., Inc. ask that you be that kind of operator.
REMEMBER:
THINK SAFETY
A CAREFUL OPERATOR IS THE
BEST INSURANCE AGAINST AN
ACCIDENT!

SubTiller 4 — Safety
• Read and understand this operator’s manual before operating.
• All machinery should be operated only by trained and authorized personnel.
• To prevent machine damage, use only attachments and service parts approved by the
manufacturer.
• Always shut tractor engine off and remove key before servicing.
• Avoid personal attire such as loose tting clothing, shoestrings, drawstrings, pants cuffs,
long hair, etc., that may become entangled in moving parts.
• Do not allow anyone to ride on the implement. Make sure everyone is
clear before operating machine or towing vehicle.
• Never attempt to operate implement unless you are in driver's seat.
Following Safety Instructions
• To avoid possible injury, lower implements to the ground before servicing.
• Avoid working under an implement; however, if it becomes absolutely
unavoidable, make sure the implement is safely blocked.
• Ensure that all applicable safety decals are installed and legible.
• When working around the implement, be careful not to be cut by sharp edges.
Before Servicing
• Do not stand between tractor and implement during hitching.
• When working around the implement, be careful not to be cut by sharp edges.
• Always make certain everyone and everything is clear of the machine before beginning
operation.
• Inspect elds for buried utility lines (electric, natural gas, water, etc.). To nd buried
lines in the US or Canada contact 1-888-258-0808, in the US you may also contact
811.
Before Operating
SubTiller 4 — Safety
1-6
• Do not allow anyone to ride on the equipment. Never dismount from
moving vehicle. Severe injury or death can occur from being run over by
the equipment.
• Regulate speed to eld conditions. Maintain complete control at all times.
• Never service or lubricate equipment when in operation.
• Keep away from overhead power lines. Electrical shock can cause serious injury or
death.
• Do not attempt to move any objects away from moving parts.
• Avoid personal attire such as loose tting clothing, shoestrings, drawstrings, pants cuffs,
long hair, etc. that may become entangled in moving parts.
• Use extreme care when operating close to ditches, fences, or on hillsides.
• Do not leave towing vehicle unattended with engine running.
During Operation
Pressurized Oil
• Relieve the hydraulic system of all pressure before adjusting or servicing. See hydraulic
power unit manual for procedure to relieve pressure.
• High-pressure uids can penetrate the skin and cause serious injury or death. Use
cardboard or wood to detect leaks in the hydraulic system. Seek medical treatment
immediately if injured by high-pressure uids.
• Hydraulic system must be purged of air before operating to prevent serious injury or
death.
• Do not bend or strike high-pressure lines. Do not install bent or damaged tubes or
hoses.
• Repair all oil leaks. Leaks can cause res, personal injury, and environmental damage.
• Route hoses and lines carefully to prevent premature failure due to kinking and rubbing
against other parts. Make sure that all clamps, guards and shields are installed correctly.
• Check hydraulic hoses and tubes carefully. Replace components as necessary if any
of the following conditions are found:
- End fittings damaged, displaced, or leaking.
- Outer covering chafed/cut or wire reinforcing exposed.
- Outer covering ballooning locally.
- Evidence of kinking or crushing of the flexible part of a hose.

Unloading Instructions
•
BEFORE REMOVING SHIPPING CHAINS OR STRAPS FROM LOAD, POSITION UNLOAD-
ING EQUIPMENT INTO FORK POCKETS OF SHIPPING FRAME.
•
READ AND UNDERSTAND SAFETY RULES BEFORE OPERATING OR SERVICING THIS
MACHINE. REVIEW THE SAFETY SECTION IN THIS MANUAL IF NECESSARY.
•
TIPPING OR MOVEMENT OF THE MACHINE CAN CAUSE SERIOUS INJURY OR DEATH.
BE SURE THE MACHINE IS SECURELY BLOCKED.
•
KEEP HANDS CLEAR OF PINCH POINT AREAS.
•
FALLING OBJECTS CAN CAUSE SERIOUS INJURY OR DEATH. DO NOT WORK UNDER
THE MACHINE AT ANY TIME WHILE BEING HOISTED. BE SURE ALL LIFTING DEVICES
AND SUPPORTS ARE RATED FOR THE LOADS BEING HOISTED. THESE ASSEMBLY
INSTRUCTIONS WILL REQUIRE SAFE LIFTING DEVICES UP TO 2000 LBS. SPECIFIC
LOAD RATINGS FOR INDIVIDUAL LOADS WILL BE GIVEN AT THE APPROPRIATE TIME
IN THE INSTRUCTIONS.
•
EYE PROTECTION AND OTHER APPROPRIATE PERSONAL PROTECTIVE EQUIPMENT
MUST BE WORN WHILE SERVICING THE IMPLEMENT.
Be sure machine is fully supported. If two machines are placed beside each other on bed
of truck, be sure the other machine is properly supported by another piece of unloading
equipment. Use unloading equipment rated to handle the intended load.
Be sure the safe lifting device is rated for the load. Use the following guidelines for determining
safe lifting device capacity requirement:
For ease of assembly, install all hardware loosely until assembly is complete and then tighten
according to Torque Chart in the MAINTENANCE section of this manual.

over level surfaces. Maintain a maximum speed of 3 MPH or less, depending upon conditions.
With shipping stand still in place, position machine onto a level, firm surface and proceed
as follows:
•BE CAREFUL WHEN WORKING AROUND COULTER BLADES. FAILURE TO DO SO COULD
RESULT IN PERSONAL INJURY DUE TO THE SHARP EDGES.
1. If coulter blades are attached to unit, remove blades and place in assembly area. Be
careful of sharp edges.
NOTE: DO NOT install these blades onto coulter hubs until after machine is safely placed
in the working position.
2. 3-Point models, raise front support stands
into the field working position and lock
into place (FIG. 2-1).
3. Be sure load is centered and safe lifting devices are hooked equally and evenly on the
