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 of 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.

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 BEFORE
OPERATING backhoe.

• Operate from backhoe operator’s 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 crowd control can

be operated together to bring bucket toward operator with

down pressure on it. As dipperstick approaches operator,

the crowd and bucket controls can be operated together to

close bucket and trap material. At end of stroke, lift and

crowd 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 crowd and bucket controls simultaneously
will insure a full bucket and prevent wasted motion and
time.
