7.5.1 Dig with the Boom
1. Use the loader arms and bucket cylinder to set the bucket
at approximately a 30-degree angle into the ground. Set the
boom angle so that the bucket teeth are digging and the
heel of the bucket is off the ground.
2. Tilt the bucket cylinder to pull the bucket through the soil
until it is full.
3. Curl the bucket up and raise the loader arms.
4. Rotate the skid steer to dump the load.

7.5.2 Dig a Trench
1. Mark the excavation area.
2. Use the boom or bucket method to dig.
3. Make the first dig shallow and accurate. The first dig keeps
the next digs accurate and the trench straight.
7.5.3 Fill Holes
Use the bucket to push or pull dirt into a hole or trench.
Pull dirt into a hole or trench:
1. Position the bucket behind the dirt pile with the hole or
trench in front. Make sure the skid steer does not get too
close to the excavation.
2. Lower the bucket close to the ground.
3. Drive the skid steer backward to pull the material into the
hole or trench.
Push dirt into a hole or trench:
1. Position the bucket in front of the dirt pile with the hole or
trench behind.
2. Lower the bucket close to the ground with the back of the
bucket facing the dirt pile.
3. Drive the skid steer forward to push the material into the
trench or hole.
7.6 Stop and Park
Take care when exiting a skid steer. Use three points of contact
and only step on non-slip surfaces.
1. Stop the skid steer on dry, level ground.
2. Lower the skid digger bucket to the ground.
3. Apply the parking brake.
4. Idle the skid steer engine for five minutes to cool it.
5. Turn OFF the hydraulic circuit.
6. Turn OFF the skid steer engine and remove the key.
7.7 Stop in an Emergency
Be familiar with the controls for your skid steer. Know how to
stop the engine and attachment quickly in an emergency.
1. Immediately release the hydraulic controls to neutral to stop
movement.
2. Apply the parking brake.
3. Turn OFF the skid steer.
4. Evaluate the situation to determine the safest way to
proceed.
