Options in detail
Engine air pre-fi lter
Large dust particles are removed in
the separator before they reach the
air fi lter.
In landfi ll applications, this results in
longer cleaning intervals for the air
fi lter cartridges and increases the
service life of the engine. Hydraulic oil thermometer
This enables the driver to keep a
constant check on the temperature
of the hydraulic oil and to respond
quickly to overheating. External air supply for alternator
Cooling air for the alternator fl ows
through the pre-screener that re-
moves debris from the air to increase
alternator life.
This option is only available for the
PR 744, PR 754 and PR 764 crawler
tractors.
Reversible fan
The optional reversible fan reverses its
direction periodically and unclogs the
cooler from accumulated debris, such
as paper or plastic parts.
This function is also available for the
separate oil cooler in the PR 744,
PR 754 and PR 764 crawler tractors.
