The MQ Whiteman All-Wheel Drive (AWD) Power Buggy,
Model WBH16EAWD (electric start) is intended for the
transportation of concrete, concrete spreading and spot
pouring. In addition, the WBH16EAWD is designed for
landscaping applications, material sub-base distribution,
job site cleanup and material transport.
The AWD Power Buggy is equipped with a 6-inch dump
height which provides clearance and enables the operator
to maneuver over any form height. In addition, it has a
unique polyethylene tub design that reduces concrete
splatter.
A low center of gravity has been incorporated into the
WBH16EAWD's design which provides added safety when
maneuvering the buggy in tight areas. A 5.5-gallon fuel tank
allows for extended uninterrupted use. Maximum speed of
the AWD Power Buggy is rated at 7.25 MPH in standard
mode and 6.2 MPH in AWD mode.
The maximum weight capacity of the AWD Power Buggy is
2,500 lbs. (1,136 kg). The outer wheels can be removed to
allow the buggy to pass through a 32 in. (81.28 cm.) door.
Hand and foot controls are provided for ease of dumping
and stopping of the WBH16EAWD. Multiple lift points have
been provided to allow for easy access of a forklift when
lifting is required.
The WBH16EAWD is powered by a Briggs and Stratton
Vanguard air cooled gasoline engine rated at 18 HP at
3600 RPM.
The engine drives a variable displacement hydrostatic
transmission which is activated by a cable controlled
hand lever. The hydraulic fluid flows to a divider valve
which directs the fluid to the forward reverse and dumping
systems.
The drive system is controlled by the AWD/2WD toggle
switch, located on the console. This switch allows the
operator to quickly change from standard drive mode (2WD)
to All-Wheel Drive mode (AWD). Toggling the switch to AWD
mode supplies power to the 12 volt solenoids and traction
assist switch. When operating in AWD mode, the top speed
of the AWD Power Buggy is reduced to 6.3 MPH.
A Traction Assist button located on the handle allows
the operator to momentarily force hydraulic fluid to both
drive motors for improved traction. Engaging the traction
assist system while in AWD mode provides enhanced
traction control by using a specialized hydraulic circuit.
This hydraulic circuit provides equal power distribution to
the front drive motors, greatly improving performance in
poor traction conditions such as sand, mud or loose gravel.
This system should only be used as needed and for short
periods of time to prevent damaging your power buggy.
The operator controls the forward and reverse machine
travel by manually shifting the control valve which directs
the hydraulic fluid flow to the two drive wheel motors. The
flow to the dump cylinder is also controlled by a manually
operated control valve.
This hydraulic system uses a parallel loop configuration,
operating at a maximum of 1450 PSI. The system also
features a neutral position which allows the AWD Power
Buggy to be moved in the event of an emergency.
The hydraulic oil is filtered by a screen type filter located in
the hydraulic tank, then doubled filtered within the system
by a 10 micron cartridge spin-on return filter.
All operators must have training before operating the
WBH16EAWD. For your safety, warnings are on the
machine and in this manual. Failure to obey these
warnings can cause severe injury or even death.
attempt to operate the power
buggy until the Safety Information, General
Information, and Inspection sections of this
manual have been read and thoroughly
understood.
