Avoid crystalline Silica (quartz) Dust
Because crystalline silica is a basic component of sand and granite, many activities at construction sites produce dust
containing crystalline silica. Trenching, sawing, and boring of material containing crystalline silica can produce dust
containing crystalline silica particles. This dust can cause serious injury to the lungs (silicosis).
There are guidelines which should be followed if crystalline silica (quartz) is present in the dust.
l Be aware of and follow OSHA (or other local, State, or Federal) guidelines for exposure to airborne crystalline silica.
l Know the work operations where exposure to crystalline silica may occur.
l Participate in air monitoring or training programs offered by the employer.
l Be aware of and use optional equipment controls such as water sprays, local exhaust ventilation, and enclosed cabs
with positive pressure air conditioning if the machine has such equipment. Otherwise respirators shall be worn.
l Where respirators are required, wear a respirator approved for protection against crystalline silica containing dust. Do
not alter respirator in any way. Workers who use tight-fitting respirators can not have beards/mustaches which interfere
with the respirator seal to the face.
l If possible, change into disposable or washable work clothes at the work site; shower and change into clean clothing
before leaving the work site.
l Do not eat, drink, use tobacco products, or apply cosmetics in areas where there is dust containing crystalline silica.
l Store food, drink, and personal belongings away from the work area.
l Wash hands and face before eating, drinking, smoking, or applying cosmetics after leaving the exposure area.
Handle Chemicals Properly
l Protective clothing should be worn.
l Handle all chemicals with care.
l Follow instructions on container label.
l Agricultural chemicals can be dangerous. Improper use can seriously injure persons, animals,
l plants, soil, and property.
l Inhaling smoke from any type of chemical fire can be a serious health hazard.
l Store or dispose of unused chemicals as specified by the chemical manufacturer.

l Do not engage power take-off while hooking-up or unhooking the driveline, or while someone is standing near the
driveline. A person’s body and/or clothing can become entangled in the driveline.
l Keep away from rotating hex drive shaft located between gearbox and drive end of tiller. A person can become entangled
in the shaft.
l Keep front rubber dirt deflector on reverse tine tillers in place while operating the unit. Objects in a reverse tine tiller can
be thrown forward toward the operator.

WWW.TMGINDUSTRIAL.COM 10 / 22 Toll Free:1-877-761-2819
l Keep yourself and all others away from rotating tines and drive train. Always disengage power take-off and lockout
power source before making adjustments or servicing the tiller. A person’s body, hair, or clothing can become entangled
in rotating components causing serious bodily injury or death.
l Make all 3-point hydraulic adjustments from the tractor seat. Never make hydraulic adjustments while standing behind
the tractor.
l Tractor power take-off shaft shield, driveline shields, and gearbox shaft shields must be installed and in good working
condition to avoid driveline entanglement and projectiles flying off of the driveline.
l Tine impact on objects can throw projectiles resulting in bodily injury or death. Do not point discharge toward people,
animals, or buildings and keep people and animals away from tiller during operation.
l Do not use a power take-off adapter. The adapter will increase strain on the tractor’s power take-off shaft causing
possible damage to shaft and driveline. It will also defeat the purpose of the tractor’s power take-off shield.
l Make certain driveline yokes are securely fastened at each end. A loose yoke can work free allowing the driveline to
rotate uncontrollably.
WARNING To avoid serious injury or death:
l
Allow only persons to operate this implement who have fully read and comprehended this manual, and who have been
properly trained in the safe operation of this implement. Serious injury or death can result from the inability to read,
understand, and follow instructions provided in this manual.
l
Never carry riders on the implement or tractor. Riders can obstruct the operator’s view, interfere with controls, be
pinched by moving components, become entangled in rotating components, struck by objects, thrown about, fall off and
be run over, etc.
l
Do not till across steep inclines that are subject to rollover. The action of the tines being forced down into the ground
can cause the tractor to roll-over resulting in serious injury or death. Consult your tractor’s manual for acceptable
inclines the tractor is capable of traveling across.
l
Check driveline when lowering tiller into the ground to make sure it does not interfere with the tractor drawbar at
maximum depth. If needed, shut tractor off and move or remove drawbar to prevent damage to the driveline.
l
Always disengage power take-off immediately after lifting tiller above ground level. Never operate tiller in the raised
position. The tiller can discharge objects at high speeds resulting in injury or death.
l
Be careful when working areas where obstructions can be hidden. Always mark potential hazards with a visible flag.
Travel slowly through high risk areas and be prepared to stop immediately should implement make contact with a solid
object.
l
Do not use implement as a man lift or work platform. It is not properly designed or guarded for this use.
l
Perform scheduled maintenance. Check for loose hardware, missing parts, broken parts, structural cracks, and
excessive wear. Make repairs before putting the implement back into service.
l
Do not use implement to lift objects; to pull objects such as fence posts, stumps, etc; or to push objects. The unit is not
designed or guarded for these uses.
l
Do not use implement to tow other equipment unless it is designed with a tow hitch. Doing so can result in loss of
control and damage the equipment.
l
Do not alter implement or replace parts on the implement with other brands. Other brands may not fit properly or meet
OEM (Original Equipment Manufacturer) specifications. They can weaken the integrity and impair the safety, function,
performance, and life of the implement. Replace parts only with genuine OEM parts.
l
Do not use implement for a purpose other than the work it is designed to do as defined in this manual.
l
Do not operate a broken or bent driveline. Such a driveline will break apart while rotating at high speeds. Always remove
the implement from use until the damaged driveline can be repaired or replaced.
l
Avoid exposure to dust containing crystalline silica particles. This dust can cause serious injury to the lungs(silicosis).
Because crystalline silica is a basic component of sand and granite, many activities at construction sites produce dust
containing crystalline silica. Trenching, sawing, and boring of material containing crystalline silica can produce dust
containing crystalline silica.
l
Some tractors are equipped with two power take-off speeds. Be certain your tractor’s power take-off shaft is set-up to
operate at 540 rpm. Do not exceed 540 rpm power take-off speed. Excessive speed can damage drive components,
cutter blades, and/or increase risk of throwing an object.

6. Clear area to be tilled of rocks, branches, and other foreign objects.
7. Tall grass and weeds should be mowed before tilling.
8. Do not engage power take-off at full throttle. Once engaged, increase throttle to 540 power take-off
speed. Tiller tines will cut better at 540 power take-off speed than at reduced throttle.
9. Tilling should not be done in wet conditions as soil will stick to tines.
10. At first begin tilling at a slow forward speed and shift up as ground conditions warrant.
11. Operate tiller with deck level to the ground.
12. Tiller tines will cut better at 540 rpm power take-off speed.
13. After tilling the first 50 feet (15.25 m), stop and check to see that the tiller is adjusted properly.
14. Do not make turns or attempt to back up while tiller is in the ground. See important note above.
15. Do not engage power take-off with implement in the fully raised position.
16. Periodically check for foreign objects wrapped around the rotor shaft and remove them after disengaging power take-off,
turning off tractor engine, and removing ignition key.
IMPORTANT: Turning or backing up with rotary tines in the ground will damage the tiller.
General Operating Instructions

the tractor, cut the driveline to proper length, run-in the clutch. If you have missed any of these steps, please complete
them before proceeding.
l Now that you have properly prepared yourself and your tiller, it’s time to do some tilling. Carefully drive the tractor to the
site where you intend to till. You should have already cleaned this site of any large limbs, rocks, trash, metal or other
debris. Best results will be achieved if you have mounted your tiller offset to the right far enough to cover the tread of
your right tractor wheel. Line the tractor up just to the right of center on your tillage plot. You will be working from the
center out and always turning to the right to line up for your next pass.
l Lower the tiller half way to the ground and reduce your tractor engine speed to about one quarter throttle. Engage the
power take-off and gradually increase the engine speed until you reach full power take-off speed of 540 rpm. Lower the
tiller to the ground and simultaneously commence forward travel of approximately 2 mph (3.2 km/h). Do not make turns
or attempt to back up while tiller is in the ground. See important note below.
IMPORTANT: Turning or backing up with rotary tines in the ground will damage the tiller.
l Travel about 50 feet (15.25 m) and then stop to check your results. When stopping, remember to lift the tiller out of the
ground, stop the tractor, reduce engine speed, disengage the power take-off, set the park brake, shut off the tractor, and
remove the key. If you are tilling too shallow or too deep, adjust the skid shoes accordingly. If the soil texture is too
coarse, lower the rear tailgate and reduce your ground speed. If the soil texture is too fine, you will need to raise your
rear tailgate and increase your ground speed. For any other problem conditions that may arise, you will want to refer to
the “Troubleshooting Chart”.
l When you are done tilling for the day, make sure you use proper tractor shutdown procedures before you get off of the
tractor. If you are detaching your tiller, make sure you park it on a dry and level surface leaving it clean and ready for the
next use.
Skid Shoe Adjustment
The skid shoes can be adjusted to the desired tilling depth by raising or lowering them:
NOTE: Tilling depth is the vertical distance from bottom of skid shoes to bottom of lowest tine. Be
certain both skid shoes are adjusted the same.
1. Raise tiller off the ground. Place support blocks under the tiller (not under the skid shoes) and lower tiller onto the
supports. Make certain the tiller is secured while resting on the supports before working on or around the tiller.

2. The park stand should be in transport position. If it is not, move it to transport position now.
3. Always place tractor in park, set tractor brakes, shut tractor engine off and remove switch key before dismounting tractor.
4. Loosen pivot bolt at the shoe’s front.
5. Remove adjusting bolt at the shoe’s rear.
6. Adjust skid shoe to the desired tilling depth.
7. Reinstall adjusting bolt and lock washer. Tighten adjusting bolt and pivot bolt to the correct torque.
Section 3: Maintenance and Lubrication
Maintenance
Proper servicing and adjustments are key to the long life of any implement. With careful inspection and routine maintenance,
you can avoid costly downtime and repair.
Check all hardware after several hours of operation and regularly thereafter to ensure they are tight and secured. Replace
worn, damaged, or illegible safety labels by obtaining new labels.
Tine Replacement
WARNING To avoid serious injury or death:
Used tines can be very sharp. Always wear gloves when handling tines to protect against cuts.
IMPORTANT: When ordering tines, be sure to order only genuine OEM tines and to order both right- and left-hand tines.
Always install tines with cutting edge facing the direction of rotation.
IMPORTANT: Remove and install one tine at a time to ensure they are oriented correctly when installed
1. Remove the two hex nuts, lock washers, bolts, and tine to be replaced.
2. Attach new tine to the mounting flange making certain it is positioned so that the cutting edge crosses over the mounting
flange and leads in rotation.
3. Replace removed bolts, lock washers, and hex nuts. Tighten hex nuts to the correct torque.
4. Repeat steps 1 to 3 until tines have been replaced.
Long-Term Storage
Clean, inspect, service, and make necessary repairs to the implement when storing it for long periods and at the end of the
season. This will help to ensure the unit is ready for field use the next time you hook-up to it.
1. Clean off any dirt and grease that may have accumulated on the tiller and moving parts. Scrape off compacted dirt from
bottom of tiller and then wash surface thoroughly with a garden hose.
2. Check tines and tine bolts for wear. Replace if necessary.
3. Inspect tiller for loose, damaged or worn parts and adjust or replace as needed.
4. Repaint parts where paint is worn or scratched to prevent rust.
5. A coating of oil may be applied to worn surfaces in lieu of painting to minimize oxidation.
6. Replace all damaged or missing decals.
7. Lubricate as noted in “Lubrication Points”.
8. Drain and refill gearboxes oil. Be sure to replace all oil plugs when completed.
1). Drain oil in central gearbox by removing bottom drain plug.
2). Drain oil in side gearbox by removing bottom level plug and tipping tiller towards the plug hole.
9. Store tiller on a level surface in a clean, dry place. Inside storage will reduce maintenance and make for a longer tiller
life.
