Check reservoir level using sight glass on the left side of the tank. If required, add to
reservoir with tractor transmission hydraulic oil (Shell DONAX TD FLUID or comparable).
Recheck oil level after the rotary hoe has been run and poil has been circulated through the
wheel and tyne motors. Routinely check level thereafter. DO NOT OVERFILL THE TANK.
Change the hydraulic oil filter after the first 50 hours of use. Change it after every 200
hours thereafter.
Add 1 quart of hydraulic oil to the reservoir with each oil filter change.
Check the tyne bolts after each use and tighten as needed., Check all hydraulic fittings for
leaks and tighten if necessary.
Tynes should be changed as often as needed for the machine to do satisfactory and
efficient rotary hoeing job. Use loctite stud and bearing adhesive/sealant on tyne bolt threads
to prevent loosening.
The grease zerks on both ends of the tynes shaft flange bearing should be greased after
every 4 to 8 hours of use.
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.
WARNING: Running the rotary hoe without hydraulic oil will cause serious damage to the
hydraulic pump. CHECK RESERVOIR LEVEL BEFORE STARTING THE MACHINE.

HOUR METER
The SenDEC®TACH/HOUR hour meter tracks the hours of machine operation in order for
routine maintenance to be performed on a timely basis.
Your SenDEC® hour meter is pre-set at the SenDEC® factory to go into Flash Alert mode at 25-
hour intervals. Although the engine manufacturer does not require changing engine oil this often,
due to heavy-duty use and extreme conditions inherent to tiller use, Red Roo
recommends frequent oil changes
strongly
.
Refer to this manual for equipment service requirements and to the Engine Manual for engine
service requirements.
While Flash Alert is active, hold the tip of the RESET TOOL (Key Cancel Wand) against the
meter as shown. Within several seconds, the display will stop flashing indicating the Service
Interval has been reset. If the wand gets lost, a small mechanic’s pick-up magnet will work.

RH918 ROTARY HOE TROUBLE SHOOTING GUIDE
CAUTION: ALW AYS USE EXTREME CARE WHEN TROUBLE SHOOTING OR MAKING
ADJUSTMENTS ON THE ROTARY HOE. STAY CLEAR OF TYNES WHEN ENGINE IS
RUNNING. ALWAYS SHUT THE ENGINE OFF BEFORE DISASSEMBLING ANY
COMPONENT.
Broken or improperly adjusted clutch
(actuator) cable.
Low hydraulic oil in tank.
Hydraulic pump-to-engine coupler
has slipped.
Hydraulic pump worn or tyne motor
relief valve not functioning properly.
Fill to centre of sight glass.
Check for wear and replace both coupler
halves and rubber spider as needed.
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 tynes and wheels in neutral, pump off about four gallons of hydraulic oil into a clean bucket.
(The .52 CID pump, @ 1000PSI & 3000 RPM, should pump at the rqate 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. Submerge the end of the hose in the hydraulic oil in the tank. (A non-collapsible
hose extension may be required ). Block the tynes with a sort 4 X 4 and stand to the side.
With tynes 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 tyne 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 tynes 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.
If broken, replace. Remove slack then
adjust for 7/16” to 1/2” movement at
actuator lever pin.

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 overheadclearances 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 tynes. Contact with the rotating tynes while in operation will cause serious injury or
even death.
MACHINE FUNCTION CHECK:If the operator releases the TYNE ENGAGEMENT CONTROL LEVER,
the rotating tynes 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.

WORK SITE ASSESSMENT
Examine the work area for any conditions or obstructions that may inhibit rotary hoeing 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 rotary hoeing activity, any evidence of possible underground placements, banks,
drop-offs, rocks, wire, uneven terrain, any existing holes and toxic ground conditions.
Only operate rotary hoe 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 rotary hoe 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 rotary hoe and any objects such
as buildings, fences, and trees.
Adequate lighting is required, daylight or artificial, for safe operation of the rotary hoe.
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 rotary hoed area by accident. Walking near the
edge of the rotary hoed area could cause loss of balance and possibly cause someone to
fall into the rotating tynes. Contact with the rotating tynes while in operation will cause
serious injury or even death.
MACHINE FUNCTION CHECK:If the operator releases the TYNE ENGAGEMENT CONTROL LEVER,
the rotating tynes 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 rotary hoe does not
function properly.
WARNING: Someone could step into the cultivated area by accident. Walking near the
edge of the cultivated area could cause loss of balance and possibly cause someone to
