COI'ITROLS and INSTRUMENTS
The controls on your new Ford 650 are designed
for efficient operation and are located within
comfortable reach of the operator, thereby
reducing operator fatigue. All instruments are
centrally located so that you can tell at a
glance whether the unit is operating properly.
The instruments also warn you of possible trouble
before it becomes serious. Before attempting to
start or operate your new Ford 650, familiarize
yourself with the location and function of all
controls and instruments as described on the
following pages.
Know your controls and instruments to assure Safe

OPERATOR'S SEAT
Your new Ford 65o is equipped with a turnabout
type seat, Figure 1. It can be adjusted forward
or rearward a maximum of seven inches (17.8 cm)
by moving the seat release lever. The height can
also be changed two inches (5.0 cm) to suite the
operator by the height adjustment knob.
ROLL OVER PROTECTIVE FRAMES (OPTIONAL)
The new Ford 650 is available with a safety frame
cab and seat belt, or a 4-post protective frame
and seat belt. Remember, the safety offered by
the protective frame alone will be minimized if
your seat belt is not buckled. Always use your
seat belt - they save lives.
CAUTION Never attach chains, ropes, or œbles to
the roll bar for pulling purposes. This is very
dangerous, as the tractor will tip backward.
Always pull from the tractor drawbar or from a
point below the rear axle. Be œreful when driving

6 The hours and portions of hours your Ford 650
has operated, is based on the average engine
speed of 1666 rpm. Engine speeds below 1666 rpm
accumulate hours at a slower rate than clock
hours. Engine speeds above 1666 rpm build up
hours faster than clock hours. Use the
Proof-Meter as a guide to determine hourly
service and maintenance intervals.
Transmission TemperatureWarning Light Check to
make sure the oil level in the transmission is at
the proper level. If the light comes on during
operation and the transmission oil level is
satisfactory, operate the engine with no-load at
1000 to 1200 rpm to cool the oil.

front corner of the fuel tank. Turning the valve
to the right will stop the flow of fuel from the
tank.
When the pressurizer blower is on, outside air is
drawn in through the filter and ventilation
louvers, Figure 11.
The hot water heater is located in the
pressurizer plenum and utilizes the pressurizer
fan for air circulation. Heat output is
controlled by the heater switch, Figure 11, and
the heater shutoff valves, Figure 12.
HOOD AND INSTRUMENT PANEL LOCKING PROVISIONS
To operate the heater, the shut-off valves must
be open for maximum heat and the heater switch
must be turned to high. To reduce heat output
turn the heater switch to low.
To help guard against vandalism and pilferage,
your new Ford 650 has hood locking provisions as
standard equipment. Figure IO shows the locking
arrangement. The tabs permit the attachment of a
padlock so the hood cannot be opened. Similarly,
an instrument panel cover is provided for
protection of the instruments. Store the
instrument panel cover in the slot provided in
the steering column shroud when not in use. See
Figure 7.
For summer operation, the shut-off valves should
be closed. If the valves remain open, hot water
will circulate through the core of the heater,
giving off radiant heat. Close the valves by
turning them clockwise.

the lever in neutral. Move the shuttle lever up
for forward travel and down for rearward travel.
TRANSMISSION DUMP VALVE CONTROL The transmission
dump valve control, Figure 15, is lo- cated on a
panel on the left loader post. The dump valve
permits the power flow to the rear wheels to be
interrupted during forward movement of the
tractor to prevent torque converter "stall" and
allow faster loader hydraulic oper- ation. The
dump valve operates only in forward speeds.
The knob on the end Of the hand brake lever
controls the hand brake tension. Refer to "HAND
BRAKE TEN- SION ADJUSTMENT" page 66, for
information on ad- justing the tension. CAUTION
Always apply the hand brake whenever the tractor
is parked as the tractor iS flee to roll even
though the transmission speed range lever and
selector lever may be "in gear".
To activate the valve, the control handle must be
pulled out and turned either right or left to
the locked position. The first position of brake
pedal travel actuates the dump valve. Partially
depressing either or both brake pedals will
interrupt the power flow to the rear wheels when
the unit is moving forward. Refer to "OPERATING
THE TRANSMISSION DUMP VALVE", page 18, for use of
the dump valve control.
TRANSMISSION CONTROLS
TRANSMISSION SPEED RANGE LEVER AND SHUTTLE LEVER
The transmission speed range lever and shuttle
lever are shown in Figure 15.
LOADER CONTROLS
The speed range lever is used to determine any of
the three working speeds. A gate, which requires
lifting the range lever to shift to 3rd gear,
allows free shifting be- tween 1st and 2ncL and
prevents inadvertently shifting to 3rd gear.
A single loader control lever, shown in the top
view of Figure 16, controls the raising and
lowering of the lift arms, and the rollback and
dumping of the bucket. In addition to the four
basic movements of left, right, forward, and
rearward, a "float" position can also be
obtained.
The shuttle lever, Figure 15, is located nearest
the steering wheel and is used to select forward
or reverse
The "float" position enables the lift arms and
bucket to follow the contour of the ground, and
is obtained by moving the control lever full
forward into the de- tent position. The lever
will remain in "float" until it is moved manually
toward neutral.

CONTROLE AND INETRUMENTS
Actuating Lever (Bucket)
The easiest way to remember component movement is
to relate lever movements to yourself when in the
operator's seat facing the backhoe. As the levers
are moved toward you, the components will move
toward you. As the levers are moved away the
components will move away from you. The farther
the levers are moved from neutral the faster the
components Will move. For precise control, all of
the levers can be "feathered" (moved slightly) to
slow element movement.

The automated backhoe functions much like the
non- automated backhoe but with less hand
movement and coordination by the operator. With
the automated back- hoe, the operator needs only
to position the selector lever on automatic and
operate the crowd lever during the bucket fill
cycle. When the bucket is full, the operator
manually completes the lift, swing, and dump
cycle. The bucket is then returned to the dig
area to begin the next automatic filling cycle.

Moving the stabilizer lever(s) forward will move
the stabilizer(s) DOWN. Moving the stabilizer
lever(s) rear- ward will move the stabilizer(s)
UP.
Refer to page 28 for additional information on
the backhoe control levers and for backhoe
operating tech- niques.
The automated backhoe also can be operated
manually as long as the selector lever is in the
manual position. When the selector lever is
turned to the manual position, move any of the
four control levers and your backhoe will respond
in the conventjonal manner.
AUTOMATED BACKHOE CONTROLS
The automated backhoe utilizes the same control
levers as the standard backhoe models. In
addition, the automat- ed backhoe incorporates a
selector lever and two ad- justing screws, Figure
19.
Adjusting Screws
The two adjusting screws, Figure 19, located on
the top of the backhoe control tower regulate
automatic bucket curl and lift to assure a full
bucket each Cycle. The adjusting screws are set
by the operator to adapt the backhoe to different
soil conditions. When differing soil conditions
are encountered, it will be necessary to turn the
adjusting screws as required to maintain the most
desirable bucket curl and lift.
The automated backhoe automatically maintains the
most desirable digging angle for efficient bucket
fill when digging long trenches or excavating.
The unique automated feature is a customer Option
which is factory installed.
Selector Lever
By positioning the selector lever, Figure 19, the
oper- ator determines whether the backhoe bucket
will be filled manually or automatically. The
setting of the two adjusting screws determinethe
bucket and lift response, and are to be adjusted
to suit the various soil conditions which may be
encountered.
The word increase on the control tower decal
means that bucket curl and lift sensitivity
(correction fre- quency) will increase when the
adjusters are turned in the direction of the
arrow (counterclockwise). 13

CONTRO LX AND INSTRUMENTS
Sensitivity and correction frequency will
"decrease" when the adjusters are turned in the
opposite diremion of the arrow (clockwise).
NOTE For an initial setting, it is suggested
that the adjusting screws be plaœd in their
mid-range position, and then be adjusted to
"increase" or "decrease" sen- sitivity and
corrections to suit operating conditions. Bath
adjusters do not have to be adjusted equally. One
may be fully dockwise while the other is fully
counterclockwise if œnditions so warrant.
When working is soft, loose soil, turn the
adjusters counterclockwise "increase" . When
working in hard, compact soil, turn the adjusters
clockwise "decrease" . Four or five turns may be
required to obtain any notice- able change in
operating characteristics.
