OPERATION

Driving the Windrower (continued)

TO DRIVE FORWARD

:

1. After starting engine, release park brake.

2. Dual Speed Units

: For field operation, set

speed-range switch (A) to position L. For road

speeds, set control to position H.

3. Slowly push throttle lever (C) to full forward

(operating speed).

IMPORTANT:

• Return throttle lever (C) to low idle position

before engaging header drives.

• For field operation, always operate windrower

with speed-range control in field position and

throttle lever fully forward (maximum engine

RPM). Use controls to vary ground speed, reel

speed and conveyor speed. All systems are

designed for efficient operation at maximum

engine RPM.

CAUTION: Check again to be sure all

bystanders have cleared the area.

4. Slowly move variable ground speed lever (D)

forward to desired speed.

CAUTION: Operate both steering

wheel and variable speed lever

slowly for familiarization. Remember

that steering is more sensitive when

speed-range control is in Road Speed Position.

Avoid the common tendency of new operators

to over-steer.

5. In situations where more tractive (lugging)

power is required, for example, driving up a

ramp, up a hill, or up out of a ditch:

Be sure speed-range control is in field position

and move the variable speed lever towards

neutral. The effect of this is similar to down-

shifting a standard transmission, increasing

torque at the drive wheels.
