Troubleshooting Chart

Problem

Cause

Solution

Hydraulic cylinder is not operating

Quick couplings did not engage.

Reconnect quick couplings to skid steer.

Skid steer hydraulic flow is not engaged.

Engage skid steer hydraulics.

Hydraulic flow from skid steer is
inadequate

Check hydraulic flow at the puller.

Skid steer is low on hydraulic oil.

Add hydraulic oil to skid steer.

Hydraulic hose has a break.

Replace hydraulic hose.

Hydraulic hose has an obstruction.

Remove obstruction or replace hose.

Hydraulic line is pinched

Fix pinched line.

Hydraulic lines have air in them.

Purge air from hydraulic lines.

Hydraulic cylinder is damaged.

Repair hydraulic cylinder.

Cylinder rod is bent.

Replace cylinder rod.

Tree does not pull

The tree has a well developed root
system.

Some species of trees are stronger than
others and won’t pull as easily. Learn
maximum sizes of each species that can
be pulled. Don’t exceed 10" with any
species.

Move skid steer forward and backward to
assist in breaking the roots free. Side to
side movement can also assist.

Use spade end of jaws to dig roots free
and to tear roots from the soil.

Soil is too wet to support the skid steer.

Wait for the soil to dry enough to support
the skid steer.

Soil is very dry and hard.

Try pulling trees once ground has firmed
up after a rain.

Post does not pull

Soil is too wet to support the skid steer.

Wait for the soil to dry enough to support
the skid steer.

Soil is very dry and hard.

Try pulling posts once ground has firmed
up after a rain.
