Diesel Particulate Filter Regeneration Important: Minimize the amount of time that you idle the engine or operate the engine at low-engine speed to help reduce the accumulation of soot in the soot filter. The diesel particulate filter (DPF) is part of the exhaust system. The diesel-oxidation catalyst of the DPF reduces harmful gasses and the soot filter removes soot from the engine exhaust.
Engine Warning Messages—Soot Accumulation (cont'd.) Indication Level Level 1: Engine Warning Fault Code g213866 Engine Power Rating Recommended Action The computer de-rates the engine power to 85% Perform a parked regeneration as soon as possible; refer to Parked Regeneration (page 43). The computer de-rates the engine power to 50% Perform a recovery regeneration as soon as possible; refer to Recovery Regeneration (page 46).
DPF Ash Accumulation • When enough ash accumulates, the engine • The lighter ash is discharged through the exhaust system; the heavier ash collects in the soot filter. • Ash is a residue of the regeneration process. Over • time, the diesel particulate filter accumulates ash that does not discharge with the engine exhaust. • • The computer for the engine calculates the amount of ash accumulated in the DPF.

Understanding the Operating Characteristics of the Machine Practice driving the machine, because it has a hydrostatic transmission and its characteristics are different than many turf-maintenance machines. Some points to consider when operating the traction unit, mower deck, or other implements are that the transmission, engine speed, load on the mower blades or other implement components affect machine performance.
After Operating After Operation To ensure optimum performance, clean the underside of the mower housing after each use. If residue builds up in the mower housing, cutting performance decreases. After Operation Safety • Clean grass and debris from the cutting units, mufflers, and engine compartment to help prevent fires. Clean up oil or fuel spills. Also, remove any debris which may have collected between the deck-lift cylinders and the foam deck pads (Figure 57).
Hauling the Machine • Use care when loading or unloading the machine into a trailer or a truck. • Use full-width ramps for loading the machine into a trailer or a truck. • Tie the machine down securely using straps, chains, cable, or ropes. Both front and rear straps should be directed down and outward from the machine. Locating the Tie-Down Points g221674 Figure 58 1.
