Leveling Blade System Schematic.
(1) Leveling blade control valve. (2) Oil line to secondary brake valve.
(3) Oil line from steering priority valve. (4) Leveling blade cylinder.
The leveling blade system is a mechanically controlled,
hydraulically operated system. The main components of the
leveling blade system are control valve (1), cylinder (4) and the
Hydraulic oil for the leveling blade system comes from the
excess flow outlet of the steering priority valve.
Leveling Blade Control Valve.
(1) Leveling blade control valve.
Blade Control Lever.
(5) Blade Control lever
Control valve (1) is located under the operator's platform. Oil
flows from the steering priority valve to control valve (1). The
control valve is a four position valve, controlled by blade
control lever (5). Control valve (1) sends oil to and from the
blade cylinder, allowing the blade to RAISE, HOLD, LOWER or
Leveling Blade Cylinder.
(4) Leveling blade cylinder. (6) Leveling blade.
Leveling blade (6) is attached to the machine at the drum yoke.
The blade is raised or lowered by retracting or extending
cylinder (4). The maximum depth of cut with the leveling blade
is 76.2 mm (3 in).
