Throttle Control
The throttle (Fig. 29) is used to operate engine at various
speeds. Moving throttle forward increases engine
speed—FAST; backward decreases engine speed—SLOW.
The throttle regulates the speed of the cutter blades or other
implement components and, in conjunction with traction
pedal, controls ground speed of the traction unit.
Seat Adjusting Lever
To adjust standard seat, push lever (Fig. 30) backward and
slide seat to the desired position. Release lever to lock seat
in place. The suspension seat may be adjusted forward or
rearward by pulling out the lever at the left side of the seat,
sliding the seat to the desired position, and releasing the
lever. The weight adjustment knob may be adjusted for any
operator’s comfort.

Starting/Stopping Engine
Important
The fuel system must be bled if any of the
following situation have occurred.
A. Initial start up of a new machine.
B. Engine has ceased running due to lack of fuel.
C. Maintenance has been performed upon fuel system
components; i.e., filter replaced, separator serviced, etc.
Refer to Bleeding The Fuel System.
1. Ensure parking brake is set, PTO switch is in OFF
position and lift lever is in TRANSPORT or FLOAT
position. Remove foot from traction pedal and insure it
is in neutral.
2. Move throttle control to 1/2 throttle position.
3. Turn ignition switch to ON / Preheat position. An
automatic timer will control preheat for 10 seconds.
After preheat, turn key to START position. CRANK
ENGINE FOR NO LONGER THAN 15 SECONDS.
Release key when engine starts. If additional preheat is
required, turn key to OFF position then to ON / preheat
position. Repeat process as required.
4. Run engine at idle speed or partial throttle until engine
warms up.
Note: Move throttle to 1/2 throttle position when restarting
a warm engine.
5. When engine is started for the first time, or after engine
oil change, or overhaul of engine, transmission or axle,
operate the machine in forward and reverse for one to
two minutes. Also operate the lift lever and PTO lever
to assure proper operation of all parts. Turn power
steering wheel to the left and right to check steering
response. Then shut engine off and check fluid levels,
check for oil leaks, loose parts and any other noticeable
malfunctions.
•
Shut engine off and wait for all moving parts to
stop before checking for oil leaks, loose parts or
other malfunctions.
Caution
6. To stop engine, move throttle control backward to
SLOW position, move PTO switch to OFF position and
rotate ignition key to OFF. Remove key from switch to
prevent accidental starting.
Bleeding Fuel System
1. Park the machine on a level surface. Make sure fuel
tank is at least half full.
2. Unlatch and raise hood.
Danger
Under certain conditions, diesel fuel and fuel
vapors are highly flammable and explosive. A fire
or explosion from fuel can burn you and others
and can cause property damage.
•
Use a funnel and fill the fuel tank outdoors, in
an open area, when the engine is off and is cold.
Wipe up any fuel that spills.
•
Do not fill the fuel tank completely full. Add fuel
to the fuel tank until the level is 1 in. (25 mm)
below the bottom of the filler neck. This empty
space in the tank allows the fuel to expand.
•
Never smoke when handling fuel, and stay away
from an open flame or where fuel fumes may be
ignited by a spark.
•
Store fuel in a clean, safety-approved container
and keep the cap in place.
