SAFETY INSTRUCTIONS
SAFETY INSTRUCTIONS
CONGRATULATIONS! On the purchase of our Rotary hoe.
This information is to assist you in preparing, operating
and maintaining your Rotary hoe. Please read and under-
stand the information completely before operating your
Rotary hoe, paying special attention to all the safety
details. Keep this manual handy for a ready reference.
YOU are responsible for the SAFE operation and mainte-
nance of your Rotary hoe. YOU must ensure that you and
anyone else who is going to operate, maintain or work
around the Rotary Hoe is familiar with the operating and
maintenance procedures and related SAFETY information
contained in this manual. This manual will take you
step-by-step through your working day and alert you to all
good safety practices that should be adhered to while
operating the Rotary hoe.
Remember, YOU are the key to safety. Good safety
practices not only protect you but also the people around
you. Make these practices a working part of your safety
program. Be certain that EVERYONE operating this equip-
ment is familiar with the recommended operating and
maintenance procedures and follows all the safety
precautions. Most accidents can be prevented. Do not
risk injury of death by ignoring good safety practices.
1. Rotary hoe owners must give operating instructions to
operators or employees before allowing them to operate
the machine.
2. The most important safety feature on this equipment
is a SAFE operator. It is the operator’s responsibility to
read and understand ALL Safety and Operating instruc-
tions in the manual and to follow these. All accidents can
be avoided.
3. A person who has not read and understood all operat-
ing and safety instructions is not qualified to operate the
machine. An untrained operator jeopardise himself and
bystanders to possible serious injury or death.
1. Read the operator’s Manual and all safety signs careful-
ly before operating, maintaining, adjusting or removing the
Rotary hoe.
2. Do not allow passengers to ride on the Rotary hoe.
3.Operate only at safe distance from bystanders. Clear
the area of people, especially small children, before start-
ing.
4. Stop PTO before dismounting tractor
5. Keep feet and hands from under rotary hoe at all times.
6. Keep all shields in place. If shield removal becomes
necessary for repairs, replace the shield prior to use.
7. Do not stay between the tractor and the Rotary hoe.
8 .Do not approach the Rotary hoe until all motion has
stopped.
9. All rotary blades have the ability to discharge objects at
high speeds, which could result in serious injury to
bystanders or passers-by, use with extreme caution.
10. Place all controls in neutral, stop tractor engine, set
park brake, remove ignition key and wait for all moving
parts to stop before servicing, adjusting, repairing,
attaching or removing.
11. Review safety related items annually with all person-
nel who will operate or maintain the Rotary hoes.
12. Do not operate machine if you feel unwell or physically
unfit, in which case you should stop working.
13. This machine was designed with safety very much in
mind. However, there is no real substitute for caution and
attention in preventing accidents. Once an accident has
happened, it is too late to think about what you should
have done.
14. Use a tractor equipped with a Roll Over Protective
Structure (ROPS). Always wear your seat belt. Serious
injury or even death could result from falling off the
tractor – particularly during a turnover when the operator
could be pined under the ROPS or the tractor.
4. Do not modify the equipment in any way. Unauthorized
modification may weaken the function and/or safety and
could affect the life of the equipment.
5. Think SAFETY! Work SAFELY!
Before operating the Rotary Hoe, read the
following safety instructions.Failure to
comply with these warnings may result in
serious injury or death.

OPERATION
OPERATION
Each rotary hoe has the same number of left and right
blades. The outer flanges have three blade end turned
inwards. The inner flange carry six blades consists of
three left and three right Make sure the front or sharpened
edge of the blades enter the soil first
The Rotary hoe is connected to the tractor by the
three-point linkage. Its installing step is as follows:
1. Align the center of headstock by reversing the tractor,
raise the link arm to appropriate height, reverse the
tractor to make the link arm of tractor joint with the left
and right pin of rotary tiller.
2. First install the left lower linkage arm, then install right
lower linkage arm, (because the leveling lift rod has screw
that can be adjusted length.) finally inert the pins.
3. Install the upper linkage arm, and then insert the pin.
4. Mount the universal coupling, and then insert the pins,
poke the cotter pin.
1. On a flat surface, lower the implement to the ground. If
not sitting level side to side, adjust the vertical linkage
arms on the three point linkage till the implement is
sitting level on the ground
2. Adjust the top link to reduce the angle at the PTO shaft
universal to the minimum at working depth. The angle of
the universal should not exceed 10º when it is working
and 30 º when it is lifted for transport. Do not engage and
operate the PTO at angle of greater then 10 º at the
universal
3. Adjust the working depth by setting the adjustable
skids to the required height
First, check the level of the gear oil in the gearbox and the
side chain box, grease the PTO Shaft and the bearing seat
of the blade shaft. Then check for the looseness of all
connecting bolts and nuts, if loose, tighten it at once. If a
crack or bent blades are found they must be replaced.
Starting tractor: Lift the hoe so the blades clear the
ground, engage the PTO and run at low revs to ensure
there is no jamming.
Soil penetration: Use PTO speed1(540RPM) & select low
creeper gear. Increase rev and lower the hoe gradually
until desired depth is met, then proceed forward.

STEP 1 Cutting the PTO shaft to length.
NOTE: Be sure to cut equal lengths of each PTO shaft
section. Clamp end of PTO shaft in a vice and cut off
shield where marked. (Figure 1-A & 1-B)
STEP 3 Repeat steps 1 and 2 for other PTO shaft section.
STEP 4 Use a file to deburr PTO shafts. Clean up all chips,
burrs and filings from both ends of the PTO shaft.
STEP 2 Using cut section of the shield as a guide cut
shaft off the same amount. (Figure 2)

MAINTENANCE & LUBRICATION
MAINTENANCE & LUBRICATION
Proper servicing and adjustment is the key to the long life
of any implement. With careful inspection and routine
maintenance, you can avoid costly downtime and repair
the parts on your rotary tiller. Do not alter the tiller in a
way which will adversely affect its performance.
Check all bolts and pins after using the unit for several
hours and on a regular basis thereafter to ensure they are
tight and secured. Replace worn, damaged, or illegible
safety labels by obtaining new labels from the dealer.
Clean, inspect, service, and make necessary repairs to
the Rotary Tiller when parking it for long periods and when
parking it at the end of a working season. This will help
ensure that the tiller is ready for field use the next time
you hook-up to it.
1. Clean off any dirt and grease that may have accumulat-
ed on the Rotary Tiller. Scrape of compacted dirt and then
wash surfaces thoroughly with a garden hose.
2. Check the tines for wear and replace if necessary.
3. Inspect the tiller for loose, damaged or worn parts and
adjust or replace if needed.
4. Lubricate as noted in “Lubrication”
5. Drain and refill gearbox and Gear case oil. Be sure to
replace all oil plugs.Drain oil in gearbox by removing the
bottom drain plug or right-hand cap.Drain oil in Gear case
by removing the bottom plug and tipping tiller backwards.
6. Replace all damaged or missing decals.
7. Store tiller on a level surface in a clean, dry place.
Inside storage will reduce maintenance and make for a
longer tiller life.
8. Repaint parts where paint is worn or scratched to
prevent rust.
For safety reasons, each maintenance
operation must be performed with tractor
PTO disengaged, tiller lowered complete-
ly to the ground or onto support blocks,
tractor engine shut off, and ignition key
removed.
Always disconnect main driveline from
tractor PTO and secure tiller in the up
position with solid supports before servic-
ing underside of tiller. PTO can be
engaged if tractor is started resulting in
damage to tiller, bodily injury, or death
Tiller should be level when checking oil
level in Gear case. Check oil level in gear
case by removing lower plug. Oil should
reach bottom of plug hole. Add recom-
mended oil as needed. Retighten plug
when oil is level with bottom of hole.
