Operation on Soft Ground
Choose the proper tracks 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.
The machine may get stuck in mud when operating on soft
ground. To remove mud buildup from the tracks, use the
following steps:
• Swing the upper structure sideways, lower the
bucket to the ground, and lift one track off the
ground. Keep the boom-arm angle between 90°
and 110° (1) with the bottom of the bucket on the
ground.
• Remove mud buildup by rotating the lifted track
back and forth. Lower the track onto the ground
and drive the machine to solid ground at low
speed.
• Pull the machine to solid ground using the boom, arm, and bucket.
• If the engine is still running when the machine is stuck, tow the machine with proper towing slings.
Removing a Stuck Machine
Be careful when operating on soft terrain to avoid
becoming stuck. If stuck in soft ground, perform the
following procedures to free the machine:
1. Swing the upper structure 90°, lower the bucket to the
ground, and lift the track on one side off the ground.
2. Keep the boom-arm angle between 90° and 110° (1)
and place the bottom of the bucket on the ground.
NOTE: Never dig the bucket tips into the earth when
the bucket is in the reversed position.
3. Place blocks under the track frame to support the
machine.
NOTICE!
Wide tracks are intended for operation on soft ground. Inspect the tracks on a regular basis.
