The engine that powers the Groundsmaster 3300 (Models 31902 and 31903)
machine is equipped with an exhaust system that includes a Diesel Particulate
Filter (DPF). The DPF includes a Diesel Oxidation Catalyst (DOC), a Soot Filter
(SF), temperature sensors, and a pressure differential sensor. The DPF is kept
clean through a series of regeneration processes that are controlled by the
engine ECU; refer to Diesel Particulate Filter (page
Reconditioning of Soot Filter (SF) may be necessary over the life of the machine
which will require exhaust system disassembly. Soot filter reconditioning should
be done by a company that has the necessary equipment. Contact your Toro
Distributor for information on reconditioning the soot filter.
The Diesel Oxidation Catalyst (DOC) has a service life expectancy and requires
replacement at recommended intervals. Replacement of the DOC will require
exhaust system disassembly.
Information about the diesel-particulate filter (DPF) operation and maintenance
can be found in the Yanmar TNV (Tier 4) Series Service Manual and the Yanmar
TNV (Tier 4) Series Troubleshooting Manual.
