Checking the Hydraulic-Fluid Level Service Interval: Before each use or daily maximum biodegradability and performance the hydraulic system should be thoroughly flushed of conventional fluid. The oil is available in 19 L (5 US gallons) containers or 55 gallon drums from your Mobil Distributor. The hydraulic tank of the machine is filled at the factory with approximately 37.8 L (10 US gallons) of high quality hydraulic fluid.
Stopping the Engine Check the Torque of the Wheel Nuts 1. Torque the wheel nuts to 94 to 122 N-m (70 to 90 ft-lb) after 1-4 hours of operation and again after 10 hours of operation. Torque every 250 hours thereafter. Important: Allow the engine to idle for 5 minutes before shutting it off after a full load operation. Failure to do so may lead to trouble on a turbo-charged engine. WARNING Failure to maintain proper torque of the wheel nuts could result in personal injury. 2.
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.
Types of diesel particulate filter regeneration that require you to park the machine: (cont'd.)

The machine is equipped with a diagnostic light which indicates if the machine detects a malfunction. The diagnostic light is located on the InfoCenter, above the display screen (Figure 45).
Checking the Interlock Switches The purpose of the interlock switches is to prevent the engine from cranking or starting unless the traction pedal is in the Neutral position, the Enable/Disable switch is in the Disable position, and the Lower Mow/Raise control is in the Neutral position. In addition, the engine should stop when the traction pedal is pressed with operator off of the seat or if the parking brake is left engaged. Sit on the seat and attempt to operate the desired function of the machine.
High Lift Parallel Sail Blade The blade generally performs better in the higher heights of cut - 7 to 10 cm (2 to 4 inch). Attributes: • More lift and higher discharge velocity. • Sparse or limp turf is picked up significantly at higher heights of cut. • Wet or sticky clippings are discharged more efficiently reducing congestion in the deck. • Requires more horsepower to run. • Tends to discharge further left and can tend to windrow at lower heights of cut.
Choosing Accessories Optional Equipment Configurations Angle Sail Blade High Lift Parallel Sail Blade (Do not use with the mulching baffle) Mulching Baffle Roller Scraper Grass Cutting: 1.9 to 4.4 cm (0.75 to 1.75 inch) Height-of-Cut Recommended in most applications May work well in light or sparse turf Grass Cutting: 5 to 6.4 cm (2.00 to 2.50 inch) Height-of-Cut Recommended for thick or lush turf Recommended for light or sparse turf Grass Cutting: 7 to 10 cm (2.75 to 4.
lush and dense grass you may have to raise the height–of–cut setting. Mowing with Sharp Blades A sharp blade cuts cleanly and without tearing or shredding the grass blades like a dull blade. Tearing and shredding causes the grass to turn brown at the edges which impairs growth and increases susceptibility to diseases. Always make sure blade is in good condition and a full sail is present. Checking the Condition of the Decks Make sure that the cutting chambers are in good condition.
