Safety
Use care when loading or unloading the machine into a
trailer or truck
The following list contains safety information specific to Toro products and other safety information you must know.
Become familiar with the safe operation of the
equipment, with the operator controls, and safety signs.
Use extra care with grass catchers or other attachments.
These can change the operating characteristics and the stability of the machine.
Follow the manufacturer’s recommendations for adding
or removing wheel weights or counterweights to improve stability.
Do not use a grass catcher on steep slopes. A heavy
grass catcher could cause loss of control or overturn the machine.
Slow down and use extra care on hillsides. Be sure to
travel in the recommended direction on hillsides. Turf conditions can affect the machine’s stability. Use extreme caution while operating near drop–offs.
Keep all movement on slopes slow and gradual. Do not
make sudden changes in speed, directions or turning.
The grass catcher can obstruct the view to the rear. Use
extra care when operating in reverse.
Never operate with the discharge deflector raised,
removed or altered, unless using a grass catcher or mulching baffles.
Keep hands and feet away from moving parts. Do not
make adjustments with the engine running.
Stop on level ground, disengage drives, chock or block
wheels, shut off engine before leaving the operator’s position for any reason including emptying the grass catcher or unclogging the chute.
If you remove the grass catcher, be sure to install any
discharge deflector or guard that might have been removed to install the grass catcher. Do not operate the mower without either the entire grass catcher or the grass deflector in place.
Stop the engine before removing the grass catcher or
unclogging the chute.
Do not leave grass in grass catcher for extended periods
of time.
Grass catcher components are subject to wear, damage
and deterioration, which could expose moving parts or allow objects to be thrown. Frequently check components and replace with manufacturer’s recommended parts, when necessary.
Safety and Instruction Decals
Safety decals and instructions are easily visible to the operator and are located near any area of potential danger. Replace any decal that is damaged or lost.

Operating and Bagging Tips
Machine Size
Remember that the machine is longer and wider with this attachment installed. By turning too sharply in confined places you may damage the attachment or other property.
Bagging Long Grass
Excessively long grass is heavy and may not be propelled completely into the bagger. If this happens, the tube and boot may plug. To avoid plugging the bagging system, mow the grass at a high height-of-cut, then lower the mower to your normal cutting height and repeat the bagging process.
Trimming
Always trim with the left side of the mower. Do not trim with the right side of the mower because you could damage the bagging tubes.
Cutting Height
For optimum bagging performance, set the deck height–of–cut to remove no more that 2 to 3 inches (51 to 76 mm) or 1/3 of the grass height, which ever is less. Cutting off more than this will reduce the capacity of the vacuum system.
Cutting Frequency
Cut the grass often, especially when it grows rapidly. You will have to cut your grass twice if it gets excessively long (refer to Bagging Long Grass, page 18).
Cutting Technique
For best lawn appearance, be sure to slightly overlap the mower into the previously cut area. This helps reduce the load on the engine and reduces the chance of plugging the boot and tube.
Bagging Speed
The bagging system may plug if you drive too fast and the engine speed gets too slow. On hills it may be necessary to slow the machines ground speed. Mow down hill whenever possible.
Bagging Wet Grass
If possible, always try to cut grass when it is dry.
Signs of Plugging
As you are bagging, a small amount of grass clippings normally blow out the front of the mower. An excessive amount of clipping blow-out indicates that the bagger is full or the boot is plugged.
Warning
Without the grass deflector, bagger tubes or complete bagger assembly mounted in place, you and others are exposed to blade contact and thrown debris. Contact with the rotating mower blade(s) and thrown debris will cause injury or death.
Never remove the grass deflector from the
mower because the grass deflector routes material down toward the turf. If the grass deflector is ever damaged, replace it immediately.
Never put your hands or feet under the mower.
Never try to clear the discharge area or mower
blades unless you move the power take off (PTO) to off and rotate the ignition key to off. Also remove the key and pull the wire off of the spark plug(s).
Caution
As the bagger fills, extra weight is added to the back of the machine. If you stop and start suddenly on hills, you may lose steering control or the machine may tip.
Do not start or stop suddenly when going uphill
or downhill. Avoid uphill starts.
If you do stop the machine when going uphill,
disengage the PTO. Then back down the hill using a slow speed.
Do not change speeds or stop on slopes.
Fan Vacuum
The bagging system operates by vacuum created by a rotating fan mounted in the top of the hopper. If the vacuum action is reduced, bagging performance will diminish. Refer to Troubleshooting on page 20 for causes of reduced performance.
Curb Climbing and Loading
Always lift the deck to the highest position when loading the machine on trailers or ascending/descending a curb. Leaving the mower in a lower position can cause damage to mower baffles while loading and going over a curb. If a
18
curb is higher than 6 inches (152 mm), cross it at a sharp angle with the deck fully raised. Use extreme caution
when loading onto a trailer.
Maintenance
Important If the machine is on a slope, chock or block the wheels to prevent the machine from slowly rolling.
Note: Determine the left and right side of the machine from the normal operating position.
