Towing
Important
Going over the limit of towing may lead to the
failure of hydraulic equipment.
Also, if the machine is towed at high speed,
the wheel may cease its motion.
Stop towing in case of wheel lock.
Resume towing at low speed after the
pressure has been stabilized.
In the event of loss of mobility due to engine
trouble or the like of, movement is possible
through towing or hand driving.
Take the shortest route when towing or hand
driving the machine.
Transport the machine on a trailer if you have
to transport it a long way.
For the towing method, see the Owner's
manual.
Neutral
If the machine goes forward or in reverse
without pressing on the forward/reverse
pedals, the neutral is not working. Adjust
accordingly.
Refer to the Owner's manual for adjustment of
the neutral.
Depressurization
Be sure to depressurize the hydraulic system
before inspecting or repairing it.
When performing depressurization, move the
machine to level surface.
Apply the parking brake, and then lower the
mower units.
Then, stop the engine and remove the key.
To depressurize the hydraulic circuit, set the
traveling pedal and all the drives of the mower
units to the neutral position.
To depressurize the steering circuit, turn the
steering wheel side to side.
Hydraulic circuit failure
The hydraulic traveling circuit of this equipment
is made up of a closed circuit.
In the event of failure of the hydraulic
equipment of the hydraulic circuit, debris and
contaminant from the faulty hydraulic
equipment will circulate to every part of the
circuit.
Since this contaminant causes damage to
other hydraulic equipment, such debris and
contaminant must be removed to prevent
further failure of other hydraulic equipment.
In the event that failure of hydraulic equipment
is found in the hydraulic circuit, remove
hydraulic hoses and piping of the whole
hydraulic circuit and clean them well with
kerosene.
Drain all the hydraulic oil from hydraulic tank
and hydraulic equipment and clean them well.
We recommend to replace the hydraulic oil,
hydraulic oil filter and defective hydraulic
equipment with new ones.
