Using the High and Low
Speed Range Switch
This machine is equipped with 2 traction speed
ranges; low and high. The speed range switch allows
you to select the following positions
•
High/Low Auto range:
Selecting the H/L AUTO position allows the
machine to automatically select between the low
and high speed ranges. The H/L AUTO position is
comparable to selecting D (drive) in your car with
an automatic transmission.
Note:
To prevent potential turf damage, the
machine will only shift between low and high range
when the traction pedal is in NEUTRAL position
and the wheels have stopped moving.
Note:
The cutting units cannot be lowered from
the transport position while you drive the machine
in the high speed range.
– When H/L AUTO position is selected and the
cutting units are lowered for mowing, the speed
range is limited to the low speed range.
– To get to high speed range, select the H/L
AUTO position on the speed range switch,
disengage the PTO, and fully raise the cutting
units.
– When H/L AUTO position is selected, the
machine will automatically switch between high
and low traction ranges based on the position
of the cutting units and/or the position of the
PTO switch.
•
Low range:
Selecting the L
position on the switch keeps the
OW
machine in the low speed range at all times. The
L
position is comparable to selecting 2, 1
OW
in your car with an automatic transmission.
– When the L
OW
machine only operates in low range.
– Use the L
position when loading the
OW
machine on a trailer or navigating tight areas
like a shop.

Using the Traction Pedal
This pedal controls the forward and reverse speed
of the machine and the dynamic braking when you
return it to neutral.
•
The traction pedal is an automotive-style
throttle—the engine speed and the machine speed
respond to the pedal movement.
•
While transporting, the traction pedal will operate
similar to a car and change the engine and traction
speed dependent on the traction pedal position.
•
While mowing, the engine automatically raises to
high idle to optimize mowing performance, and the
L
OR
traction pedal only controls traction speed.
•
The further you push the pedal forward or reverse,
the faster the machine moves.
•
To control the machine to a smooth stop while
transporting or mowing, use your foot to return the
traction pedal to neutral at your desired rate.
•
To engage maximum braking, remove your foot
from the traction pedal, allowing it to return to
neutral. The machine dynamically brakes to a
stop.
This traction system allows you to customize the
acceleration settings for operator comfort and course
conditions. Refer to
