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.
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.
Types of Diesel Particulate Filter Regeneration Types of diesel particulate filter regeneration that are performed while the machine is operating: Type of Regeneration Conditions for DPF regeneration DPF description of operation Passive Occurs during normal operation of the machine at high-engine speed or high-engine load The InfoCenter does not display an icon indicating passive regeneration.

Blade Maintenance cutting edge of the blade at the same position as in step 2. Blade Safety Note: The difference between the dimensions obtained in steps 2 and 3 must not exceed 3 mm (1/8 inch). If the dimension exceeds 3 mm (1/8 inch), the blade is bent and must be replaced; refer to Removing and Installing the Mower Blade(s) (page 73). DANGER A worn or damaged blade can break, and a piece of the blade could be thrown at you or bystanders, resulting in serious personal injury or death.
Inspecting and Sharpening the Mower Blade(s) Consider 2 areas when checking and servicing the mower blade—the sail and the cutting edge. Both cutting edges and the sail, which is the turned-up portion opposite of the cutting edge, contribute to a good quality of cut. The sail is important because it lifts the grass up straight, thereby producing an even cut. However, the sail gradually wears down during operation.
Correcting a Mower-Deck Mismatch Note: Remove the blades and sharpen them on a grinder. After sharpening the cutting edges, install the blade with the anti-scalp cup and blade bolt; refer to Removing and Installing the Mower Blade(s) (page 73). If there is mismatch between the blades, on a single mower deck, the grass will appear streaked when it is cut. This problem can be corrected by ensuring that the blades are straight and all of the blades are cutting on the same plane. 1.
Storage Preparing for Seasonal Storage Traction Unit 1. Thoroughly clean the traction unit, mower decks, and the engine. 2. Check the tire pressure; refer to Checking the Tire Pressure (page 24). 3. Check all fasteners for looseness; tighten as necessary. 4. Grease or oil all grease fittings and pivot points. Wipe up any excess lubricant. 5. Lightly sand and use touch-up paint on painted areas that are scratched, chipped, or rusted. Repair any dents in the metal body. 6.
