LeeBoy 8608 - Augers; Hopper and Conveyors; Hydraulic System; Screed

screed operator using the remote screed keypad on
each side of the paver.
The augers can also be controlled manually or
automatically using sonic sensor technology. The sonic
sensor can be mounted on either screed end gate,
where it monitors and controls the pile height of material
at the discharge end of the augers.
The dual augers are hardened, 3/4-inch thick, 12-inch
round, HRC 55-60 augers that can operate in reverse.
The modular auger assembly, in one-foot sections,
allows for a simple quick change of the assembly.
Hopper and ConveyorsHopper and Conveyors
Material in the hopper is moved toward the back of
the paver to the screed by conveyors. The narrow,
automatic conveyors with a wide hopper design delivers
asphalt more evenly and efciently to produce a smooth
asphalt mat. The hopper’s rounded design reduces
cold material build-up while rear hopper wing wipers
help prevent spillage.
Conveyor chains are easily adjusted from underneath
the paver. Front conveyor sprockets offer longer wear
and better chain tracking to eliminate material build-up.
Hydraulic SystemHydraulic System
Separate pumps for the various functions enhance
the paver’s hydraulic power. The hydraulic system
consists of a tandem drive pump, a tandem cylinder
and charge pump, and a tandem conveyor and auger
pump, along with hydraulic motors and cylinders that
work together for optimum machine component control.
Valves regulate the directional, pressure and uid ow
throughout the hydraulic system. Manifolds are set up
to allow for all options. Screed function manifolds are
mounted onto the screed. Dual, brushless fan 162,000
BTU oil cooler with bypass improves reliability.
AugersAugers
Right and left augers rotate
to move material from the
conveyors to the screed.
The augers can be operated
independently of the other
and controlled from the

Track SystemTrack System
The paver drive system contains two heavy-duty torque
hubs that propel the hydrostatically-powered, self-
cleaning tracks with self-adjusting front idlers. Two-
speed motors power tough planetary drives for smooth
operation.
ScreedScreed
The LeeBoy 8608 Commercial Paver is equipped with
the Heavy Duty 815HD screed. It features heavy-duty
ight screws, heavy-duty crown and valley mechanism
and 3-Adjuster AOA (Angle of Attack) with vertical
height adjustment for even more screed control. A
9-function screed control box is located on each side of
the paver.
The main screed has hydraulic extensions on each side
that extend and retract to allow paving widths from 8 - 15
feet. Electric dual vibrators mounted on the main screed
frame increase paving material compaction. The main
screed can be locked in the raised position for travel,
service and overnight parking for additional stability.
The screed heat system is designed for maximum
performance and efciency. It is heated by a 14.4 kW
generator that maintains heat for the screed and end
gates. S-curve heating elements in the main screed with
straight heating elements in the extensions cycle during
heat-up to save horsepower and fuel consumption while
paving. Heat cycles can be controlled by automatic time
or the optional Automatic Timer Control system.
