Float Positioning Control Check
Refer to Figure 2-2:
Gauge wheels must be installed before setting tractor
operator levers to float position. Install gauge wheels per
“Gauge Wheels (Optional)” instructions on page 20.
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 in the Adjustment
section. Refer to
“Turtle/Rabbit Flow Control at the
Tractor” on page 32 for detailed instructions.
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 22).
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.
