KUBOTA WORKSHOP MANUAL, DIESEL ENGINE,
05--E3B SERIES
General Information
This Chapter gives information about specifications,
troubleshooting, testing and repair of the Kubota diesel
engine used in the Groundsmaster 4300--D.
Most repairs and adjustments require tools which are
commonly available in many service shops. The use of
some specialized test equipment is explained in the en-
gine workshop manual included at the end of this chap-
ter. However, the cost of the test equipment and the
specialized nature of some repairs may dictate that the
work be done at an engine repair facility.
Service and repair parts for Kubota diesel engines are
supplied through your local ToroDistributor . If a parts list
is not available, be sure to provide your distributor with
the Toro model and serial number.
Operator’s Manual
The Operator’s Manual provides information regarding
the operation, general maintenance and maintenance
intervals for the Kubota diesel engine that powers your
Groundsmaster machine. Refer to that publication for
additional information when servicing the machine.
Stopping the Engine

smaster 4300--D is turbo--charged. Before stopping
theengineafter mowing or full load operation,cool
the turbo-charger by allowing the engine to idle at
