Operation Section 4-3

LEFT HAND STABILIZER

Push lever forward, left hand stabilizer lowers. Pull lever

back, left hand stabilizer raises.

RIGHT HAND STABILIZER

Push lever forward, right hand stabilizer lowers. Pull lever

back, right hand stabilizer raises.

OPERATING BACKHOE

CAUTION: To avoid possible injury, observe

the following safety rules WHEN OPERATING

backhoe.

Operate from backhoe operators seat only.

Lower stabilizers until weight of tractor is

supported by stabilizers. Do not lift tractor tires

off ground.

Do not dig near stabilizers.

Do not attempt to raise tractor off ground or

move tractor forward or backward using

backhoe dipperstick or bucket.

Do not lose stability by swinging bucket downhill

when positioned on a slope.

It is not difficult to become an efficient operator. Control

operating decals are located in front of control levers.

Study these decals. They will assist you in becoming

familiar with the controls.
Smooth, light handling of controls will result in the most

efficient backhoe operation.
Operate backhoe control levers to become familiar with

their speed and movements. Engine speed and PTO

RPM will determine speed of cylinder operation.
Swing boom several times to practice controlling the

speed of swing. Do not operate swing more than 45

degrees each way for the first few times. Gradually

increase the arc.
Best results are obtained by digging near center of swing

arc so material can be dumped on either side.
As operator becomes more familiar with operation of

backhoe, it will be common practice to operate two

controls at one time. For example with bucket extended

and dipperstick extended, the lift control and dipperstick

control can be operated together to bring bucket toward

operator with down pressure on it. As dipperstick

approaches operator, the dipperstick and bucket controls

can be operated together to close bucket and trap

material. At end of stroke, lift and dipperstick controls are

operated to move load up and away from operator to save

time in clearing excavation.

This dual operation of controls will speed and simplify

digging operation. Normally two or more movements will

not be equal or even simultaneous but as pressure within

the cylinders, and resistance of an operating member of

backhoe lessens, it will begin to move. It is balancing the

force of one member against another.

NOTE: Actuating bucket is the key to powerful digging.

Operating the dipperstick and bucket controls

simultaneously will insure a full bucket and prevent

wasted motion and time.

OPERATION

OPERATION

DIPPERSTICK/BUCKET

Push lever forward, dipperstick moves away from operator.

Pull lever back, dipperstick moves toward operator.
Move lever to left, bucket curls in. Move lever right, bucket

extends out.
By moving lever to one of the intermediate positions,

dipperstick can be extended or retracted at the same time as

bucket is being loaded or dumped.
Move dipperstick away and extend bucket by moving lever

forward and to the right.
Move dipperstick toward operator and curl bucket by moving

lever back and to the left.
Move dipperstick away and extend (dump) bucket by

moving lever forward and to the right.
Move dipperstick toward operator and extend bucket by

moving lever back and to the right.
The two operations of the boom and swing lever combined

with the two operations performed by bucket and dipperstick

control lever provide four simultaneous operations from the

two levers. Oil flow will go to operation which requires the

least pressure. The ability to feather valve spools and

balance pressure comes with experience resulting in

reduced cycle times.
