MACHINE OPERATION
SY95C Excavator OMM
Operating on Soft Ground
NOTICE!
• Rugged terrain could cause tracks with wide
shoes to bend or come loose and damage other
track components.
• Wide track shoes are intended for operation on
soft ground.
• Inspect the track shoe fasteners on a regular
basis.
Choose the proper track shoes when operating the
machine on soft ground. Soft ground may cave in and
cause the machine to roll over. Place steel plates on soft
ground to support the machine.
Removing a Stuck Machine
Be careful when operating on soft terrain to avoid
becoming stuck.

If your machine becomes stuck, perform the following
procedures to free the machine:
WARNING
Use caution when placing cribbing under the
track. The machine is supported only by the boom
and could drop without warning. Failure to follow
this warning could result in death or serious
injury.
One Track Stuck
1. Position the boom and arm at an angle (1) between
90° and 110°.
2. Pivot the upper structure to position the boom over
the track that is stuck.
3. Curl the bucket so that the back of the bucket
touches the ground.
4. Lower the boom to raise the track.
WARNING
Rotating tracks are dangerous. Stay away from
rotating tracks. Failure to follow this warning
could result in death or serious injury.
5. Remove mud buildup by operating the lifted track
forward and backward.
6. Place cribbing under the track to provide a firm
surface if necessary.
7. Raise the boom to lower the track onto the cribbing.
8. Drive the machine out of the mud.
Two Tracks Stuck
1. Position the boom and arm at an angle between
90°and 110°.
2. Pivot the upper structure to position the boom over
the front of the machine.
3. Curl the bucket so that the back of the bucket
touches the ground.
4. Lower the boom to raise the front of the tracks off the
ground.
5. Place cribbing under the tracks to provide a firm
surface if necessary.
6. Raise the boom to lower the tracks onto the cribbing.
7. Cut the bucket into the ground in front of the
machine. Retract the arm (as with normal
excavating) while driving the machine forward out of
the mud.
If the machine does not move, tow the machine. See
“Towing the Machine” on page 4-27.
If the machine is not operational, it may need to be
moved using a lifting device. See “Lifting the Machine” on
page 4-35.
