3.6 SERVICE HYDRAULIC OIL
The machine is shipped with hydraulic oil in the reservoir. Run the machine for
approximately 15 minutes to allow any extra air to purge out of the hydraulic system.
Check hydraulic reservoir and if necessary fill the reservoir to the appropriate level with
Mobil 1 15W-50 synthetic motor oil. Replace hydraulic reservoir cap and tighten until
snug.
Do not overtighten.
NOTE: The baffle is labeled “HOT” and “COLD”. The oil level varies with the
temperature of the oil. The “HOT” level shows the level of oil when it is at 225°F
(107°C). The “COLD” level shows the level of the oil when it is at 75°F (24°C). Fill to
the appropriate level depending upon the temperature of the oil. For example: If the
oil is about 150° F (65°C). Fill to halfway between the “HOT” and “COLD” levels. If
the oil is at room temperature (about 75° F (24°C)), fill only to the “COLD” level.

4.1 CONTROLS
4.1.1
Familiarize yourself with all controls before operating the mower.
4.1.2
Steering and Motion Control:
Speed Control lever, located on RH console, sets maximum forward speed.
Moving speed control lever rearward to the neutral position places the drive
system in neutral.
Pulling back on the steering levers, centered in front of the seat, progressively
slows, then reverses the direction of travel of the respective drive wheels.
By moving both steering levers an
equal
amount back, the machine can be
slowed down or travel backward in a straight line.
Steering is controlled by varying the position of the steering levers relative to
each other.
To
turn left
while moving forward, move the left steering lever back toward
neutral to slow the left drive wheel.
To
turn right
wile moving forward, move the right steering lever back toward
neutral to slow the right drive wheel.
To turn to the left while backing, move the left lever forward toward neutral. To
turn to the right while backing, move the right lever forward toward neutral.
NOTE: The unit may be moved in reverse while the speed control is in the
neutral position by pulling back on the steering levers.
