Diesel particle filter

The exhaust system of a tractor is equipped with a diesel particle filter which serves for cleaning
exhaust fumes. Solid particles (carbon particles) are collected and burned in diesel particle filter which
originate by burning diesel.

Filter of solid particles - indication of operation and failures of the system

The activity of a DPF filter is indicated by lights (1), (2) and (3) on the instrument panel.
More in the chapters Instrument panel and Exhaust gas aftertreatment.

Diesel particle filter regeneration

During operation of the tractor, the DPF filter is clogged with solid particles generated by the fuel combustion
as the engine is running.
The clogged DPF filter is regenerated (cleaned) by the increased exhaust temperature of the standing tractor
during engine run. WARNING: When regenerating the DPF particulate filter, the temperature of the
exhaust gases and the surface of the particulate filter will rise sharply.
There is an increased risk of fire or explosion if DPF particulate filter regeneration occurs in an
environment with a fire hazard or in an explosive environment.
When working with a tractor in an environment where the risk of fire or explosive atmospheres occurs, the
DPF filter regeneration must be immediately interrupted or the environment left for the DPF filter
regeneration.
More in chapters Dashboard and Exhaust Gas Treatment System.
During operation of the tractors with the engine equipped with the filter of solid particles avoid
long-term operation at idling or at low engine load.
Driver´s seat - safety switch
The driver´s seat is equipped with a safety switch which
signalizes the system of driver abandoning the driver´s
seat.
If the tractor is started, there is nobody on the driver´s seat
and reversing lever under the steering wheel is shifted to
F or R position, N position is shifted automatically and
tractor does not start.
If this situation occurs, it is necessary to sit on the driver´s
seat, to return the reversing lever under the steering wheel
to N position and then to select the direction of drive again
(F or R).
