The LeeBoy LBC-24W Concrete Curb and Gutter machine is a maneuverable, compact machine that
enhances job-site productivity, speed and quality. Steering controls turn a smooth radius as tight as 24 inch-
es eliminating time-consuming hand forming. The LBC-24W is designed to cost-effectively slipform curbs
and gutters, alley ribbons and sidewalks. The hydrostatic variable speed drive, superior visibility and elec-
tronic controls enable a one person operation. The LBC-24W can be used on soil or pavement using a
string line or manual controls. Pouring molds can be replaced quickly and easily with the quick-change mold
system.

GENERAL INFORMATION
The descriptions and specifications given in this
section are applicable to the LBC-24W Curber. This
section contains a description of how the major
components operate. It also includes the hydraulic,
electrical, performance, and fluid specifications used
on this machine.
ENGINE
The LBC-24W Curber uses a Kubota four-cylinder
diesel engine to drive the hydraulic pump. The
engine is mounted inside the engine compartment
located underneath the hopper. The engine is
accessed through the engine compartment door and
by lifting the hopper.
A fuel pump mounted on the engine draws diesel
fuel from the fuel tank. The fuel tank is mounted at
the right rear of the machine with a fill cap at the top
rear (Figure 2-1). The fuel tank has a shutoff valve
installed on the fuel outlet to shut off the fuel during
service.
FIGURE 2-1. FUEL SUPPLY
Air Cleaner
An air cleaner is mounted on top of the engine and
filters intake air before use by the engine. The air
cleaner removes fine particles such as dust, sand,
chaff and lint from the air (Figure 2-2).
As air is taken into the air cleaner assembly, a
cyclone type action deposits some of the fine parti-
cles in the evacuator mounted on the bottom of the
air cleaner housing. The evacuator is held closed
during engine operation by suction. When the
engine is shut off the weight of the debris helps to
open the rubber flaps allowing the debris to fall out.
The rubber flaps can also be squeezed together for
cleaning.

Filters
A fuel filter removes contaminants from the diesel
fuel before the fuel flows to the injection pump for
injection into the engine combustion chamber. See
Figures 2-3 and 2-4 for location of engine fuel and
oil filters.
FIGURE 2-3. FUEL FILTER
Radiator
A radiator mounted at the right side of the Curber
cools the engine. As coolant flows through the radia-
tor, airflow from the engine driven fan removes heat
from the coolant.
Refer to the engine manufacturer's manual for a
complete description of the engine.
FIGURE 2-4. ENGINE OIL FILTER
ELECTRICAL SYSTEM
The electrical system is powered by a 12-volt bat-
tery mounted in the battery compartment located
inside the front access door of the machine
(Figure 2-5).
FIGURE 2-5. BATTERY
The battery is 12 volts DC and maintained at 950
cold cranking amperes (CCA). An engine-mounted
alternator keeps the battery charged during normal
operation.
A warning light mounted on the control panel warns
the operator if the battery rate falls to a critical level
(Figure 2-6).

HYDRAULIC SYSTEM
The hydraulic system includes a hydraulic pump
driven by the engine (Figure 2-7). The pump is
mounted on the rear of the engine. This variable dis-
placement pump provides hydraulic pressure and
flow to operate all the hydraulic components used to
control the Curber functions.
The pump draws hydraulic oil from the reservoir
(Figure 2-8) and delivers pressurized oil flow to the
hydraulic control valve mounted inside the front
access door.
The hydraulic reservoir has a sight and temperature
gauge installed to check and monitor hydraulic oil
conditions (Figure 2-8).

DRIVE SYSTEM
The LBC-24W drive system includes three hydro-
static variable speed hydraulic motors, control valve
assembly, electronic flow control valve,
combiner/divider assembly, and a counterbalance
valve.
The drive motors are mounted for all wheel drive.
The hydraulic oil pressure to the motors is divided
and maintained for smooth operation of the drive
wheels.
The drive direction and speed are controlled using a
Forward/Reverse Toggle Switch, Drive Torque
Adjustment Knob, and Variable Drive Low/High
Knob all mounted on the control panel (Figure 2-9).
Brakes
Machine braking is controlled by the flow of
hydraulic oil in the drive system. When the drive
switch is returned to neutral from forward or reverse
position, the flow of hydraulic oil to the drive motor
stops rotating the drive motors allowing the machine
to slow and stop.
Steering
The front drive wheel is also used for steering the
machine. A hydraulic cylinder mounted between the
Curber frame and swiveling wheel mount allows the
machine to be turned from left to right. The control
valve controls the hydraulic cylinder. A Left/Right
Toggle Switch mounted on the control panel (Figure
2-9) allows the operator to manually steer the
machine.
The steering can also be controlled by the Top-Con
Computer Control System (Figure 2-9). A Steering
Computer ON/OFF Toggle Switch mounted on the
control panel activates computer controlled steering.
Steering sensors located on the left side of the
Curber monitor the steering path and send signals
to the computer for steering correction. These sen-
sors are selected using the Steering Selector Switch
mounted on the control panel.

HOPPER
The hopper is mounted on the top of the machine
above the mold. The hopper holds the concrete
used to form curbs (Figure 2-10).
Dual hydraulically operated vibrators keep the con-
crete flowing from the hopper to the mold. The oper-
ation of the vibrators is controlled by Left and Right
Vibrator Toggle Switches mounted on the control
panel (Figure 2-9). Left and Right Vibrator Speed
Knobs, mounted on the Main Control Panel, control
vibrator speed.
MOLDS
Molds mounted on the lower rear section of the hop-
per determine the final shape and size of the curb
(Figure 2-11).
Weights mounted on the rear of the mold help stabi-
lize the mold during curbing operations. Two weights
are used when curbing and finishing are being per-
formed at the same time. One weight may be
removed during curbing only operations. The oper-
ator will make this decision based on the consisten-
cy of the concrete being used.

CONTROL SENSORS
The machine can be placed in an automatic mode
allowing the Top-Con computer system to control
curbing functions. Refer to USING THE TOP-CON
SYSTEM in Section 3. Once the curbing parame-
ters are set and the computer system is activated,
control sensors mounted on the left side of the
machine send signals to the computer indicating the
need for steering, height, and slope adjustments
(Figure 2-12).
FIGURE 2-12. CONTROL SENSORS
COMPUTER CONTROL SYSTEM
All curbing operations can be preset and performed
using the Top-Con computer control system. The
computer system is used in conjunction with the
control sensors, and is pre-set, adjusted, and moni-
tored using the controls and monitoring screen
mounted on the control panel (Figure 2-13).
The sensors ride on a string line installed on the
perimeter of the curbing area (Figure 2-12). The
sensors signal the computer system when steering,
height and slope adjustments are necessary.
