CONTROL VALVE - BOOM CONTROL
Maverick Boom Control System
:
1. Operating the Boom Control functions is done so by means of a load sensing electronic
over hydraulic system. There are three main areas of that system, the electronic network,
instrumentation and hydraulic components.
2.
System components are, The hydraulic System, The electronic network, The instrumen-
tation and Operator Interface.
3.
The Hydraulic System, The hydraulic components are responsible for transferring me-
chanical power into hydraulic power. There are two separate hydraulic circuits, the boom circuit
and the mower head circuit.
4.
How the boom is controlled, The system progression starts with operator input at the
joystick (Figure 6- Item A) or other instrumentation. Input is received at the CAN module (Figure
5- Item B) and joins the network. That information is transferred via the network to the valve solenoid
(Figure 5- Item C) which activates and moves the spool sending hydraulic fluid pressure to the
cylinder (Figure 5-Item D) and moves the load.

Maverick Mower Head Circuit
:
1. The Motor Circuit. The motor circuit for the cutting head operation is operated through
display (Figure 6- Item A). By selecting the activation parameter the coil will shift the servo-piston
at the hydrostatic pump (Figure 7-item B), stroking the pump into the "On" position. Flow will then
be supplied to the hydraulic motor at the cutter head (Figure 6-Item C). Activate the motor circuit
while the engine RPM is at idle. Once activated, the engine RPM can be raised to the 540 PTO
required speed, if the 540 PTO engine speed is not noted on the tractors RPM gauge consult tractor
owners manual to find what the required speed is. At any time the Emergency stop switch (Figure
7-Item D) located on the joystick will deactivate the cutter motor circuit. The blade will stop within
6 second when the emergency switch is shut "Off"
