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. A rollover can occur before the tires lose traction. Avoid operating the machine on wet grass.
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.

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. • Inspect the blade periodically for wear or damage. • Use care when checking the blades.
5. Rotate the marked end of the blade to the 3 and 9 o’clock positions (Figure 101) and measure the heights. 6. Compare the 12 o’clock measured height to the height-of-cut setting. It should be within 0.7 mm (0.030 inch). The 3 and 9 o’clock heights should be 1.6 to 6.0 mm (0.060 to 0.240 inch) higher than the 12 o’clock setting and within 2.2 mm (0.090 inch) of each other. height then no adjustment is needed for that side. Adjust the other side to within ± 2.2 mm (0.090 inch) of the correct side. 7.
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 75). 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 14). 3. Check all fasteners for looseness; tighten as necessary. 4.
10. Check the anti freeze protection and add a 50/50 solution of water and ethylene glycol anti-freeze as needed for the expected minimum temperature in your area. Mower Deck If the mower decks are separated from the traction unit for any length of time, install a spindle plug in the top of the spindles to protect the spindles from dust and water. g036712 Figure 106 1.
