SKID STEER REQUIREMENTS
AND PREPARATION
Both the manual and hydraulic positioning skid steer
post driver mounts are designed to fit skid steer units
with the “Universal” (Bobcat) style quick-attach loaders.
The model 16, 22Q, and 26Q post drivers vary as to the
size post they can drive and the amount of impact force
they can strike a post with. (Refer to Specifications.)
A larger size skid steer unit is required in relation to the
size of driver used. A general rule is that the skid steer
specified operation lift capacity should be at least 1.25
times the weight of the post driver attachment.
A post driver is equipped with adjustable legs which
should be adjusted to the proper height and have the
weight of the driver on them while driving the post. This
makes the driver a more stable unit and eliminates shock
loads on the skid steer loader.
Be sure that the skid steer unit is in good working order,
particularly the hydraulic system, prior to using the post
driver. Be sure the skid steer hydraulic oil and filter have
been serviced according to the skid steer manufacturer’s
recommendations.
■
Be sure your skid steer and loader is in good
condition. Read all the safety precautions and
make sure all operators are familiar with the safety
rules of operation.
■
Post drivers are tall and visibility of the top of the
post driver may be obstructed by the top of the
skid steer unit operators cab. Always be aware of
low doorways, low limbs, and especially low hang-
ing wires.
A heavy load can cause instability in driving a skid
steer unit. Always drive slowly – especially around
turns. An unstable skid steer unit could steer badly
and possibly tip over, causing damage, injury or even
death.
INSTRUCTIONS
These instructions are for the models HPD-16 HSS/P,
HPD-22Q HSS/P, and HPD-26Q HSS/P skid steer
mounted hydraulic post drivers.
The model 16, 22Q, and 26Q HSS/P post drivers have
a hydraulic motor with a self-contained hydraulic system.
The hydraulic system of the skid steer unit powers the
motor only.
The Models HPD-16 HSS/P has the Quick Change
Cylinder Cap.
The models HPD-16 MSS and HPD-22Q MSS are
manually adjusted post drivers. The manual adjusting
base have two threaded cranks to set the side to side
and front to back positioning of the driving ram.
Models HPD-22Q and HPD-26Q have both the Quick
Change Cap and the new longer lasting Quick Change
spring assemblies.
The models HPD-16 HSS/P, HPD-22Q HSS/P, and
HPD-26Q HSS/P have the driving ram positioning con-
trolled hydraulically. A two spool hydraulic valve controls
the front to back and side to side movement for aligning
to a vertical ram position. A separate single spool valve
controls the raising and lowering of the driving ram.
The hydraulic valve that operates the driving ram is a
convertible valve and is shipped ready for OPEN center
hydraulic systems. Do not change this valve to a closed-
center valve. This convertible feature is only required for
some farm tractor applications.
Post drivers are a tall attachment to your skid steer unit.
Always watch for low clearance problems such as low
tree limbs, doorways, or low hanging wires.
WARNING
CAUTION
