LeeBoy 6150 Conveyor Paver 4-37
Operation
Topcon® Sonic Slope and Dual
Grade Control
Sonic trackers continuously measure the elevation over
the surface, automatically averaging and adjusting the
tow point cylinder on the paver. The LCD digital display
is easy to see regardless of light conditions.
Choose from one of three options: Sonic Grade Control
(one side); Dual Grade Control or Dual Grade Control
and Slope (both Topcon P-32 systems). The dual
grade controls automatically maintain a set depth on
both ends of the screed. The Dual Grade and Slope
controls maintain a set depth on one end of the screed
and a set slope to the other end.
Most states require this technology for state road paving
jobs to ensure smoothness and continuity on roadways.

screed control for improv-
ing smoothness along
with assuring accurate
slope and material thick-
ness. These controllers
send signals to the screed
to precisely maintain mat
thickness and slope as
you pave.
Berm Screed Extension Attach-
ment
The Berm Screed Extension Attachment (HD Screed
only) allows you to adjust the last one foot of each
extension to pave up to a four-inch roll-up curb. (Figure
4-77) You can also raise the height to easily allow more
material alongside buildings or other objects on various
paving jobs. The berm attachment is adjustable while
paving and controlled via a remote toggle switch.
