Bush Hog 2175 - Manual (Page 10)

GENERAL OPERATION
CAUTION
To avoid possible injury,
observe the following
safety rules BEFORE
OPERATING the backhoe:
1. BE SURE area is clear of
underground utilities or
other hazards.
2. POSITION barricade
around work area.
3. PROVIDE adequate
front end weight to
counter-balance tractor at
all times. 20% of the total
tractor, loader and back-
hoe weight must be on the
tractor front axle.
4. Keep bystanders a safe
distance away.
DIRECTIONS: The terms right, left, front and back
shall be determined from the position of the operator
when seated in the operating position on the backhoe.
Engine Speed
The speed at which the backhoe operates is partially
dependent on engine RPM. Use a moderate engine
speed to start and increase it as your experience per-
mits. Refer to “SPECIFICATIONS” for hydraulic flow
volume requirements. When powering from tractor
systems with higher output, reduce engine RPM to
obtain acceptable backhoe operating speed.

CONTROLS
The backhoe has two major control levers plus the
stabilizer control levers. These controls are located on
the control console directly ahead of the operator. See
Figure 2. The following is a list of the controls, with the
function of each, reading from left to right.
1. Left Hand Stabilizer: Push lever forward, the LH
stabilizer lowers. Pull lever back, the LH stabilizer
raises.
2. Boom/Swing: Push lever forward, the boom
moves down, away from the operator. Pull lever back,
the boom moves up, toward the operator.
The Boom/Swing Control Lever has an added “float”
function. A detent or stop should be felt when the lever
is pushed forward to move the boom down. Pushing
the lever forward more will overcome the detent and
cause the boom to float, or move down or up freely,
depending on the forces acting on it. When the lever
is released it should return to the center, neutral posi-
tion.
Move lever to the left, the backhoe swings to the left.
Move lever to the right, the backhoe swings to the
right.
By moving the lever to one of the intermediate posi-
tions, the boom can be swung left or right at the same
time it is being raised or lowered, performing the two
operations simultaneously.
SWING LEFT AND LOWER the boom by moving the
control lever forward and to the left.
