Section 2: Hydraulic Set-up Options
Momentary ON Push Button Checks
IMPORTANT: If included, make sure "Deck Float"
and/or "Deck Motor" push buttons are "OFF".
Cycle "ARM 1", "ARM 2", and "Deck Pivot" cylinders to
ensure they operate properly as follows:
1. Read and understand hooking-up and unhooking
"Transport Safety Chain" on page 17. Remove
transport safety chain from the latched position and
place loose end on storage hook.
2. Start tractor and adjust 3-point hitch until PTO
driveline is approximately level.
3. Extend and retract hydraulic cylinders as follows:
Solenoid Control
a. Do not engage PTO for this check.
b. Two hoses for operating "ARM 1", "ARM 2", and
"Deck Pivot" cylinders are connected to a duplex
outlet on the tractor. Lock control lever for that
duplex outlet in either "Extend Position" or
"Retract Position".
c. Refer to Figure 2-14: Press and hold push button
labeled "ARM 1 OUT" momentary. The inboard
parallel arm should start to extend outward. If it
does not move, or moves in the wrong direction
(retracts), you should do one of the following:
•
Change the position of the tractor control lever
from automatic retract to automatic extend or
vice-versa.
•
Reverse hoses at the duplex outlet.
•
Check hydraulic plumbing to and from the
solenoid box to make sure hydraulic hoses are
not plumbed in reversed order.

d. Check hydraulic fluid level in your tractor's
reservoir. If low, add fluid to the system before
continuing. The cylinders and hoses will require
approximately 1 3/4 gallons from the tractor.
Independent Control
a. Check Hydraulic Reservoir. Make sure it is full of
hydraulic oil and shut-off valve is fully OPEN.
b. With tractor engine at an idle, engage PTO and
then increase engine speed to about half the
cutter rated PTO speed.
c. Refer to Figure 2-14: Press and hold push button
switch labeled "ARM 1 OUT" (See Arrow)
momentary. The inboard parallel arm should start
to extend outward. If it does not move, or moves in
the wrong direction (retracts), you should do one
of the following:
•
•
4. After "ARM 1" has been verified to function correctly,
purge hydraulic system of air as follows:
a. Press and hold push button labeled "DECK
DOWN" until deck is in the horizontal position.
b. Press and hold push button labeled "ARM 2 OUT"
until the outboard parallel arm is fully extend.
c. Press and hold push button labeled "ARM 1 OUT"
until the inboard parallel arm is fully extend.
d. Repeat steps a to c in reverse order to retract all
three cylinders.
e. Cycle the cylinders to full extension and retraction
several times to make sure all air is purged.
