Be aware that there is no rollover protection when a folded roll bar is in the down position.
Check the area that you will be mowing and never fold down a folding roll bar in areas where there are slopes, drop-offs, or water.

Slope Safety

Slopes are a major factor related to loss of control and rollover accidents, which can result in severe injury or death. You are responsible for safe slope operation. Operating the machine on any slope requires extra caution.
Evaluate the site conditions to determine if the slope is safe for machine operation, including surveying the site. Always use common sense and good judgment when performing this survey.
Review the slope instructions, listed below, for operating the machine on slopes. Before you operate the machine, review the site conditions to determine whether you can operate the machine in the conditions on that day and at that site. Changes in the terrain can result in a change in slope operation for the machine.
- Avoid starting, stopping, or turning the machine on slopes. Avoid making sudden changes in speed or direction. Make turns slowly and gradually.
- Do not operate a machine under any conditions where traction, steering, or stability is in question.
- Remove or mark obstructions such as ditches, holes, ruts, bumps, rocks, or other hidden hazards. Tall grass can hide obstructions. Uneven terrain could overturn the machine.
- Be aware that operating the machine on wet grass, across slopes, or downhill may cause the machine to lose traction.
- Use extreme caution when operating the machine near drop-offs, ditches, embankments, water hazards, or other hazards. The machine could suddenly roll over if a wheel goes over the edge or the edge caves in. Establish a safety area between the machine and any hazard.
- Identify hazards at the base of the slope. If there are hazards, mow the slope with a pedestrian-controlled machine.
- If possible, keep the cutting units lowered to the ground while operating on slopes. Raising the cutting units while operating on slopes can cause the machine to become unstable.

Operation

Before Operation

Performing Daily Maintenance

Before starting the machine each day, perform the Each Use/Daily procedures listed in the Maintenance Schedule.

Fuel

Fuel Specifications

Important

Use only ultra-low sulphur diesel fuel. Fuel with higher rates of sulfur degrades the diesel oxidation catalyst (DOC), which causes operational problems and shortens the service life of engine components.

Failure to observe the following cautions may damage the engine.

Never use kerosene or gasoline instead of diesel fuel.
Never mix kerosene or used engine oil with the diesel fuel.
Never keep fuel in containers with zinc plating on the inside.
Do not use fuel additives.

Petroleum Diesel

Type	Use summer grade diesel fuel (No. 2-D) at temperatures above -7°C (20°F) and winter grade (No. 1-D or No. 1-D/2-D blend) below that temperature. Use of winter grade fuel at lower temperatures provides lower flash point and cold flow characteristics which eases starting and reduces fuel filter plugging. Use of summer grade fuel above -7°C (20°F) contributes toward longer fuel pump life and increased power compared to winter grade fuel.
Sulfur content	Ultra low (<15 ppm)
Minimum Cetane Rating	45
Storage	Acquire only enough clean, fresh diesel fuel or biodiesel fuel that you will consume within 180 days. Do not use fuel that has been stored for more than 180 days.
Oil and additives	Do not add to the fuel

Diesel fuel must meet:	Standard	Location
	ASTM D975	USA
	No. 1-D S15
	No. 2-D S15
	EN 590	European Union
	ISO 8217 DMX	International
	JIS K2204 Grade No. 2	Japan
	KSM-2610	Korea

Biodiesel

Type	This machine can also use a biodiesel-blended fuel of up to B20 (20% biodiesel, 80% petroleum diesel). The petroleum diesel portion must be ultra low sulfur (<15 ppm). Use B5 (biodisel content of 5%) or lesser blends in cold weather
Minimum Cetane Rating	40
Biodiesel Precautions	Painted surfaces may be damaged by biodiesel blends. Monitor seals, hoses, gaskets in contact with fuel as they may degrade over time. Fuel filter plugging may be expected for a time after converting to biodiesel blended. For more information on biodiesel, contact your authorized Toro distributor.

If the machine was run at full-load operation, allow the engine to idle for 5 minutes.

Important

Idling the engine for 5 minutes allows the turbocharger to cool down before shutting off the engine. Failure to do so may lead to turbocharger damage.

Rotate the key to Off and remove the key.
Wait for all moving parts to stop.

Locking the Cutting-Unit Pivot

Cutting Grass on a Hill Side

Lock the cutting-unit pivots to prevent the cutting units from rotating downhill when cutting across the face of a hill.

G423878

Secure the carrier frame of the cutting unit to the pivot yoke with the snapper pin .
Repeat step 1 at the other cutting units.

Adjusting the Turf-Compensation Spring

The turf-compensation spring transfers the weight from the front roller to the rear roller. This helps to reduce a wave pattern in the turf, also known as marcelling or bobbing.

Important

Make spring adjustments with the cutting unit mounted to the traction unit, pointing straight ahead and lowered to the ground.

G402845

Make sure that the hairpin is installed in the rear hole in the spring rod .

Note: When servicing the cutting unit, move the hairpin to the spring-rod hole next to the turf-compensation spring .
Tighten the hex nuts on the front end of the spring rod until the compressed length of the spring is 15.9 cm (6.25 inches).

Diesel Particulate Filter Regeneration

DPF Soot Accumulation

Over time, the diesel particulate filter accumulates soot in the soot filter. The computer for the engine monitors the soot level in the DPF.
When enough soot accumulates, the computer informs you that it is time to regenerate the DPF.
DPF regeneration is a process that heats the DPF to convert the soot to ash.
In addition to the warning messages, the computer reduces the power produced by the engine at different soot-accumulation levels.

Engine Warning Messages—Soot Accumulation

Indication Level	Fault Code	Engine Power Rating	Recommended Action
Level 1: Engine Warning	G411639 Check Engine SPN 3719, FMI 16	The computer de-rates the engine power to 85%.	Perform a parked regeneration as soon as possible.
Level 2: Engine Warning	G411641 Check Engine SPN 3719, FMI 0	The computer de-rates the engine power to 50%.	Perform a recovery regeneration as soon as possible.

DPF Ash Accumulation

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.
When enough ash accumulates, the engine computer sends information to the InfoCenter in the form of an engine fault to indicate the accumulation of ash in the DPF.
The fault messages indicate that it is time to service the DPF.
In addition to the warnings, the computer reduces the power produced by the engine at different ash-accumulation levels.

InfoCenter Advisory and Engine Warning Messages—Ash Accumulation

Indication Level	Fault Code	Engine Speed Reduction	Engine Power Rating	Recommended Action
Level 1: Engine Warning	G411642 Check Engine SPN 3720, FMI 16	None	The computer de-rates the engine power to 85%.	Service the DPF.
Level 2: Engine Warning	G411642 Check Engine SPN 3720, FMI 16	None	The computer de-rates the engine power to 50%.	Service the DPF.
Level 3: Engine Warning	G411644 Check Engine SPN 3720, FMI 16	Engine speed at maximum torque + 200 rpm	The computer de-rates the engine power to 50%.	Service 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 that cause 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 show an icon indicating passive regeneration. During passive regeneration, the DPF processes high-heat exhaust gasses, oxidizing harmful emissions, and burning soot to ash. Refer to Passive DPF Regeneration.


Assist	Occurs because of low-engine speed, low-engine load, or after the computer detects the DPF is becoming obstructed with soot	The InfoCenter does not show an icon indicating assist regeneration. During assist regeneration, the engine computer adjusts the engine settings to raise the exhaust temperature. Refer to Assist DPF Regeneration.


Reset	Occurs every 100 hours	When the high exhaust-temperature icon is shown in the InfoCenter, a regeneration is in progress. During reset regeneration, the engine computer adjusts the engine settings to raise the exhaust temperature. Refer to Reset Regeneration.
	Also occurs after assist regeneration only if the computer detects that assist regeneration did not sufficiently reduce the soot level

Types of diesel particulate filter regeneration that require you to park the machine:

Type of Regeneration	Conditions that cause DPF regeneration	DPF description of operation
Parked	Occurs because the computer detects back pressure in the DPF due to soot buildup	When the reset-standby/parked or recovery regeneration icon or Advisory #188 shows in the InfoCenter, a regeneration is requested. Perform the parked regeneration as soon as possible to avoid needing a recovery regeneration. A parked regeneration requires 30 to 60 minutes to complete. You must have at least a 1/4 tank of fuel in the tank. You must park the machine to perform a parked regeneration. Refer to Parked or Recovery Regeneration.
	Also occurs because the operator initiates a parked regeneration
	May occur because you set the InfoCenter to inhibit reset regeneration and continued operating the machine, adding more soot when the DPF already needs a reset regeneration
	May result from using the incorrect fuel or engine oil



Recovery	Occurs because the operator ignored requests for a parked regeneration and continued operating the machine, adding more soot to the DPF	When the reset-standby/parked or recovery regeneration icon or Advisory #190 shows in the InfoCenter, a recovery regeneration is requested. A recovery regeneration requires up to 3 hours to complete. You must have at least a 1/2 tank of fuel in the machine. You must park the machine to perform a recovery regeneration. Refer to Parked or Recovery Regeneration.
