Console Control Lever Functional Checks
!
DANGER
Hydraulic fluid under pressure can penetrate skin. 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 hydraulic leaks. If
hydraulic fluid is injected into the skin, it must be treated by a
doctor within a few hours or gangrene may result.
The hoses on each outlet should be connected such that
when the control lever is pushed forward, the arm
(or deck) extends. Cycle hydraulic cylinders with tractor
console controls to ensure they operate properly as
follows:
Pre-Operational Instructions
1. Read and understand "Transport Safety Chain" on
page 17 before continuing.
2. Remove transport safety chain from its latched
position and place loose end on the storage hook.
3. Start tractor and adjust 3-point hitch until PTO
driveline is approximately level.
Control Lever Center Detent Position Check
Refer to Figure 2-2:
1. Operate tractor console control lever designated for
"ARM 1" by pushing it forward briefly to see which
way the inboard arm moves. It should extend
outward. If "ARM 1" retracts, reverse hydraulic hoses
at the duplex outlet (See Figure 2-1 on page 19).
2. Repeat this procedure for "ARM 2" and "Deck Pivot"
cylinders.

3. After hose hook-up has been verified to be correct,
purge hydraulic cylinders of air in the order below:
a. Push on deck control lever to lower the deck down
into a horizontal position.
b. Push on "ARM 2" control lever until the outboard
parallel arm is fully extend.
c. Push on "ARM 1" control lever until the inboard
parallel arm is fully extend.
d. Repeat steps a to c in reverse order to retract all
three cylinders.
e. Cycle cylinders to full extension and retraction
several times to make sure all air is purged.
4. Check hydraulic fluid level in your tractor's reservoir.
If low, add fluid to the tractor's hydraulic system
before proceeding. The cylinders and hoses will
require approximately 1 3/4 gallons from tractor
reservoir.
Float Positioning Control Check
Gauge wheels must be installed before setting tractor
operator levers to float position. Install gauge wheels per
"Gauge Wheels (Optional)" instructions on page 18.
To make this functional check, "ARM 1" and "ARM 2"
must extended about half way. The Rotary Cutter deck
should be resting on its gauge wheels.
1. Operate all three tractor console control levers and
lower gauge wheels to ground level.
2. Set only "ARM 2" and "DECK" control levers in float
position. Consult tractor manual if operator is unsure
of where float position is for the tractor control levers.
3. Retract "ARM 1" control lever. "ARM 2" and "Deck
Pivot" cylinders should float (change position)
allowing deck gauge wheels to remain resting on the
ground.
4. Return control levers to center detent position to
regain full control of "ARM 2" and "Deck Pivot" pivot
cylinders.
Flow Control (Turtle/Rabbit Adjustments)
Flow control adjustments are made later in the
Adjustment section. Refer to "Turtle/Rabbit Flow Control
at the Tractor" on page 28 for detailed instructions.
