FLOAT Control
Refer to Figure 2-8 on page 32:
The control stick is equipped with a FLOAT detent button.
The float control should only be used if the cutter deck is
equipped with gauge wheels and the gauge wheels are
on the ground.
1. Press FLOAT detent button to turn on the float
function. The ARM2 and DECK cylinders move freely
allowing the deck to follow the contour of the ground.
2. Press and release the Float detent button to turn float
function off and to regain control of ARM2 and DECK
cylinders.
3. Pressing and releasing the detent button will turn
float function on and off repetitively.
4. While in float, ARM1 toggle switch still functions to
move the deck in or out.
Float Detent Button ON
When pressed in, the FLOAT button allows the deck to be
carried on the gauge wheels. The DECK and ARM2
momentary rocker switches are bypassed allowing the
deck position to change with the terrain. Press the FLOAT
button in only when deck is equipped with gauge wheels
and after the deck wheels are resting on the ground for
cutting.
Float Detent Button OFF
When pressed and released (popped-out), the FLOAT
detent button is set to OFF and will allow all three
momentary rocker switches (ARM1, ARM2, & DECK) to
be individually operated.
Turn FLOAT detent button OFF:
•
When transporting the cutter.
•
When encountering raised areas such as banks,
stumps, rocks, or other protrusions that the gauge
wheels cannot and/or should not roll over.
•
When crossing ditches that will cause the deck to
become high centered or gauge wheels to catch
stopping forward travel.
•
When the operator wants full control of the cutter deck
and parallel arms.
Control Stick Functional Checks
Refer to Figure 2-11 on page 35:
Momentary OUT/IN Rocker Switches
Cycle ARM1, ARM2, and DECK cylinders to ensure they
operate properly as follows:
1. Check Hydraulic Reservoir. Make sure it is full of
hydraulic oil and shut-off valve is fully OPEN.
2. Unhook Transport Safety Chain. Stow loose end in
3. Start tractor and adjust 3-point hitch until driveline is
approximately level.
4. With tractor engine at an idle, engage power take-off
and then increase engine speed to about half the
rated power take-off speed.
5. Press and momentarily hold ARM1 OUT rocker
switch (See Arrow in Figure 2-11) to see which way
the inboard arm moves. The inboard arm should start
to extend outward.
6. Repeat step 5 for ARM2 and DECK cylinders.
7.
Return cylinders to their fully retracted position.
8. If one or more cylinders did not move or moved in the
wrong direction (retracts), you should shut the tractor
down according to
on page 45 and make the following checks:
•
Check hydraulic plumbing to and from the
solenoid box to make sure hydraulic hoses are
not plumbed in reverse order.
•
Check electrical layout to make sure the wiring
is correct.
9. After hose hook-up and electrical connections have
been verified to be correct, purge hydraulic cylinders
on
ON/OFF Push Button & Rocker Switches
Refer to Figure 2-11 on page 35:
WARNING
!
To avoid serious injury or death:
•
Hydraulic fluid under high pressure can penetrate the skin
and/or eyes causing a serious injury. Wear protective gloves
and safety glasses or goggles when working with hydraulic
systems. Use a piece of cardboard or wood rather than
hands when searching for leaks. A doctor familiar with this
type of injury must treat the injury within a few hours or
gangrene may result. DO NOT DELAY.
IMPORTANT:
Before engaging the tractor power
take-off, make sure the reservoir is full of hydraulic
oil and the shut-off valve is turned on.
IMPORTANT:
Make sure FLOAT and DECK MTR
switches are OFF.
