2.6 SAFETY PRECAUTIONS

Safe Operation Practices for Ride-On Mowers

This cutting machine is capable of amputating hands
and feet and throwing objects. Failure to observe the
following safety instructions could result in serious
injury or death. Your complete and unimparied
attention is required at all times.

General Operation

Read, understand, and follow all instructions in this
owners manual, the engine manual and on the
machine before starting.

Only allow responsible adults, who are familiar with the
instructions, to operate the machine.

Clear the area of objects such as rocks, toys, wire, etc.,
which could be picked up and thrown by the blade.

Be sure the area is clear of other people and pets
before mowing. Stop machine if anyone enters the
area.

Never carry passengers.
Do not mow in reverse unless absolutely necessary.

Always look down and behind before and while
backing.

Be aware of the mower discharge direction and do not
point it at anyone. Do not operate the mower without
either the entire grass catcher or the guard in place.

Slow down before turning to prevent tipping or loss of
control.

Never leave a running machine unattended. Always
turn off blades, set parking brake, stop engine, and
remove keys to prevent unauthorized use before
dismounting.

Turn off blades when not mowing.

2 - 4

Disengage mower clutch, stop engine, remove key and
wait for moving parts to stop before leaving operators
position for any reason such as removing grass catcher
or unclogging chute.

Mow only in daylight or good artificial light.
Do not operate the machine while under the influence

of medication, alcohol or drugs.
Watch for traffic when operating near or crossing

roadways or drives.
Use extra care when loading or unloading the machine

into a trailer to truck.
Use only attachments or accessories designed for your

unit. See your Ariens Dealer.
Wear sturdy foorwear. Do not operate riding mower

barefoot or when wearing open sandals or canvas
shoes. Do not wear loose clothing that may get caught
in rotating parts of unit. Wear safety glasses with side
shields when operating mower.

Slope Operation

Slopes are a major factor related to loss-of-control and
tip-over accidents, which can result in severe injury or
death. All slopes require extra caution. If you cannot
back up the slope or if you feel uneasy on it, do not
mow it.

Do

Mow up and down slopes, not across.
Remove obstacles such as rocks, free limbs, etc.
Watch for holes, ruts, or bumps. Uneven terrain could

overturn the machine. Tall grass can hide obstacles.
Use slow speed. Choose a low gear so that you will not

have to stop or shift while on the slope.
Follow the manufacturer’s recommendations for wheel

weights or counterweights to improve stability.
Use extra care with grass catchers or other

attachments. These can change the stability of the
machine. Use only approved hitch points.

Limit loads to those you can safely control.
Keep all movement on the slopes slow and gradual. Do

not make sudden changes in speed or direction.
Avoid starting or stopping on a slope. If tires lose

traction, disengage mower clutch and proceed slowly
straight down the slope. If you must stop when going
up the slope and can not safely back down: for gear
drive models, depress clutch/brake pedal, disengage
mower clutch, place travel speed selector in first gear
(low speed) and slowly release the clutch/brake pedal.

For hydro models depress clutch/brake pedal only if
necessary, disengage mower clutch, slowly release
clutch brake pedal and slowly engage the forward
pedal.

Do Not

Do not turn on slopes unless necessary, and then, turn
slowly and gradually, downhill, if possible.

Do not mow near drop-offs, ditches, or embankments.
The mower could suddenly turn over if a wheel is over
the edge of a cliff or ditch, or if an edge caves in.

Do not mow on wet grass. Reduced traction could
cause sliding.

Do not try to stabilize the machine by putting your foot
on the ground.

Do not use grass catcher on steep slopes.

Children

Tragic accidents can occur if the operator is not alert to
the presence of children. Children are often attracted to
the machine and the mowing activity. Never assume
that children will remain where you last saw them.

Keep children out of the mowing area and under the
watchful care of another responsible adult.

Be alert and turn machine off if children enter the area.
Before and when backing, look behind and down for

small children.
Never carry children, even when attachments are off.

They may fall off and be seriously injured or interfere
with safe machine operation.

Never allow children to operate the machine.
Use extra care when approaching blind corners,

shrubs, trees, or other objects that may obscure vision.

Service

Do not change engine governor setting or over speed
the engine.

Replace damaged or worn out mufler immediately.
Continued use could result in fire or explosion.

Use extra care in handling gasoline and other fuels.
They are flammable and vapors are explosive.

Use only an approved container.
Never remove gas cap or add fuel with the engine

running. Allow engine to cool before refueling. Do
not smoke. Wipe off any spilled gasoline and allow
vapors to dissipate before starting engine.

Replace fuel tank cap and container cap securely.
Never refuel the machine indoors.
Never store the machine or fuel container inside

where there is an open flame, such as in a water
heater.

Never run a machine inside a closed area. Exhaust
fumes contain carbon monoxide an odorless and
deadly gas.

Keep nuts and bolts, especially blade attachment bolts,
tight and keep equipment in good condition.

Never tamper with safety devices. Check their proper
operation regularly.

2 - 5

Keep machine free of grass, leaves, or other debris
build-up. Clean up oil or fuel spillage. Allow machine to
cool before storing.

Stop and inspect the equipment if you strike an object.
Repair any damage before restarting.

Never make adjustments or repairs with the engine
running or when engine and exhaust parts are hot from
operation.

Grass catcher components are subject to wear,
damage, and deterioration, which could expose moving
parts or allow objects to be thrown. Frequently check
components and replace, with manufacturer’s
recommended parts when necessary.

Mower blades are sharp and can cut. Wrap the
blade(s) or wear gloves, and use extra caution when
servicing them.

Check brake operation frequently. Adjust and service
as required.

Refer to Storage Section of this owners manual if unit
is to be stored for extended period.

4.11 CHECKING THE TRANSMISSION

Figure 10

936-8

Figure 11

936-9

FLUID (HYDRO)

The transaxle is filled and tested at the factory and
should not require fluid when the unit is put into
service. Inspect the transaxle for leaks or damage to
the housing. If leakage is observed, do not operate
until the leakage is repaired.

Check the oil level and fill to the correct level if needed.

3. Start engine and run at low idle.

4. Stroke the travel control pedal

forward for five
seconds and then reverse for five seconds. Do this
three times in each direction.

Figure 9

936-7

The oil should be between 1.25 and 1.60" from the top
of the housing in the 310-0750 axle. It may be checked
by removing the expansion hose. Typically, an API
classificat ion CG/ CD en gin e oi l i s us ed w ith a vi sc os it y
range equivalent to 20W50.

4.12 PRIMING THE TRANSMISSION
(HYDRO)

The following is suggested for the priming of new or
repaired transaxles to assure proper operating
performance.

1. Locate the unit on a flat level surface to limit the
chance of the unit rolling while performing the
following procedures.

2. Actuate the bypass

(freewheel control).

5. Return the travel control to neutral.

6. Disengage the bypass and drive the unit forward
and then reverse. Do this three times each way for
a distance of approximately five feet.

7. Some units may require repeating the previous six
steps to achieve proper operating performance.

4.13 CHECKING THE PTO CLUTCH

Measure Clutch Coil Resistance:

1. Turn engine and power take off (PTO) switch off.

2. Disconnect clutch wire connections.

3. Set meter to check ohms.

4. Connect meter leads in clutch connector.

5. If meter reads below 6.00 ohms or above 8.00
ohms, then the clutch has failed and needs to be
replaced.

6. If meter reads between 6.00 to 8.00 ohms, proceed
to measure clutch current draw.

Measure Clutch Current Draw

1. Turn engine off.

2. Remove 30 amp fuse.

3. Set meter to check amps (10 amp scale).

4. Connect one meter lead to the fuse holder.

5. Connect the other meter lead to the second wire in
the fuse connector.

6. Turn the ignition switch to run, sit on the seat and
turn the PTO switch to on.

7. If the meter reads below 3.5 amps, the problem
would be in the electrical system leading to the
clutch (battery, relay, switch wiring).

If after completing the tests:

• The resistance falls between 6.00 and 8.00 ohms.

• The amp draw is 3.50 or above.

The electric clutch is within factory specifications and is
not the source of the problem.
