If you feel uneasy operating the machine on a slope, do not do it. Watch for holes, ruts, bumps, rocks, or other hidden objects. Uneven terrain could overturn the machine. Tall grass can hide obstacles. Choose a low ground speed so you will not have to stop or shift while on a slope.
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 Servicing the Blade Plane Blade Safety The mower deck comes from the factory preset at 5 cm (2 inches) height of cut and blade rake of 7.9 mm (0.310 inch). The left and right heights are also preset to within ± 0.7 mm (0.030 inch) of the other. A worn or damaged blade can break, and a piece of the blade could be thrown toward you or bystanders, resulting in serious personal injury or death. The mower deck is designed to withstand blade impacts without deformation of the chamber.
Removing and Installing the Mower Blade(s) Adjusting the Blade Plane Start with the front adjustment (change 1 bracket at a time). 1. Remove the height-of-cut bracket, (front, left, or right) from the deck frame (Figure 101). 2. Adjust 1.5 mm (0.060 inch) shims and/or 0.7 mm (0.030 inch) shims between the deck frame and bracket to achieve the desired height setting (Figure 101). Replace the blade if it hits a solid object, is out of balance, or if it is bent.
Inspecting and Sharpening the Mower Blade(s) Two areas must be considered 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.
Storage 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).
