Hydraulic System Setup
IMPORTANT
The hydraulic system setup information contained in
the following sections should be used only as a guide.
Consult your local Hardee dealer or mower
manufacturer for more detailed information.
Working Safely with Hydraulic Lines
Purge all air from hydraulic system before attempting
to raise or lower the mower boom and deck.
DANGER
Stand clear if lowering or raising deck, hydraulic deck
can fall suddenly from system failure.
DANGER
Do not use your hand or skin to check for hydraulic
leaks, use cardboard or wood. High-pressure oil leaks
can penetrate skin causing injury and gangrene.
Consult a doctor immediately. Always wear safety
goggles when working around high-pressure lines.
Description of Operation
The LR50160 is set-up at the factory as a self-
contained hydraulic system. This means that the
mower pump powers ALL hydraulic functions.
A Programmable Processor (Refer to Page 25)
controls four cylinder functions (swing, first stage
boom lift, second stage boom lift, and mower deck tilt)
and one motor function which drives the mower head.
A single tethered handheld grip serves as the operator
input. The grip includes a dead-man bar, a left two-
axis thumb controlled proportional joystick, a right two-
axis thumb controlled proportional joystick and a
momentary switch controlling a latching circuit turning
the mower head motor on and off. A proximity switch
is used to decelerate the swing velocity near both
stroke ends.
Joystick Functions
 Left X-axis (horizontal) controls Deck Down (W)
and Deck Up (E).
 Left Y-axis (vertical) controls First Stage Boom Up
(N) and Boom Down (S).
 Right X-axis (horizontal) controls Swing Left (W)
and Swing Right (E). Proximity switch decreases
output to Swing by 50% when actuated.
 Right Y-axis (vertical) controls Second Stage
Boom Up (N) and Boom Down (S).
 LED should be Red when mower head motor is
active and Green when the system is active but
the mower head is off. LED remains active if
dead-man is released until system hibernates.
 Push Button controls mower head motor. Motor
switches on when dead-man bar is depressed and
push button is held for two seconds. Motor
switches OFF when push button is instantly
depressed or fifteen seconds after the dead-man
bar is released.
 System becomes active when Dead-Man Bar is
depressed for two seconds. Bar must remain
depressed for all control functions to be active
except for the fifteen second motor off delay
mentioned above. System Hibernates after ten
minutes of inactivity on the Dead-Man Bar.
Refer to Figure 2 for joystick functions on Page 10.
