CONGRATULATIONS on the purchase of a new collection system. It has been designed, engineered and manufactured to give you the best possible dependability and performance.
Should you experience any problem you cannot easily remedy, please contact the nearest authorized service center/ department. They have competent, well­trained technicians and the proper tools for service and repairs.
Please read and retain this manual. The instructions will enable you to assemble and maintain the collection system properly. Always observe the SAFETY RULES.
KNOW YOUR BLOWER SYSTEM
READ THIS OPERATION MANUAL AND SAFETY RULES BEFORE ASSEMBLING OR OPERATING THE BLOWER SYSTEM. Compare the illustrations with the carton contents and become familiar with the parts before starting the assembly. Study the operating instructions and safety precautions thoroughly to insure proper functioning of the Grass Catcher and to prevent injuries. Save this manual for future reference.
CAUTION
BEFORE ASSEMBLING GRASS CATCHER TO MOWER:
Set parking brake.
Place motion control levers in NEUTRAL position.
Turn ignition key OFF and remove key.
Make sure the blades and all moving parts have completely stopped.
CAUTION
DO NOT operate mower with grass catcher partially installed.
Disengage blades and stop engine before leaving mower seat to empty containers, unclogging chutes, etc.
Close cover before starting.
Disengage mower blades when crossing driveways or gravel surfaces and other areas where thrown objects could be a hazard.
DO NOT attempt to vacuum cans or other potentially hazardous projectiles.
CAUTION
The operation of any mower can result in foreign objects thrown into the eyes, which can result in severe eye damage. ALWAYS wear safety glasses or eye shields before starting the mower and while mowing. Standard safety glasses are recommended or a wide vision safety mask for over spectacles.
CAUTION
Do not leave grass in bagger containers. Empty containers after each use and before storing. Failure to do so may result in spontaneous combustion which could develop into a fire.
CAUTION
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 RULES

SAFE OPERATION PRACTICES FOR RIDE-ON MOWERS
GENERAL OPERATION
Read, understand and follow all instructions in the manual and on the machine before starting.
Only allow responsible adults, who are familiar with the instructions, to operate the machine.
Clear the area of objects such as rocks, stones, toys, wire etc., which could be picked up and thrown by the blades.
Be sure the area is clear of all people and pets before mowing. Stop the machine if anyone enters the area.
Never carry passengers or children even with blades off.
Do not mow in reverse unless absolutely necessary. Always look down and behind before and while backing.
Do not operate the mower without either the entire grass catcher or the guard in place.
Slow down before turning.
Stop engine before removing grass catcher or unclogging chute.
Mow only in daylight or good artificial light.
Do not operate the machine while under the influence of alcohol or drugs.
If the collection system has front weights included, DO NOT operate mower with the grass catcher unless the front weights are installed.
Keep machine free of grass, leaves or other debris buildup which can touch hot exhaust/ engine parts and burn. Do not allow the mower deck to plow leaves or other debris which can cause buildup to occur.
Allow machine to cool before storage.
SLOPE OPERATION
Slopes are a major factor related to loss-of-control and tip-over accidents, which can result in severe injury or death. All slopes require extra caution. If you cannot back up the slope or if you feel uneasy on it, do not mow it.
DO
Use extra care with grass catchers or other attachments. These can change the stability of the machine.
Mow up and down slopes (10° Max.), not across.
Remove obstacles such as rocks, tree limbs, etc.
Watch for holes, ruts, or bumps. Uneven terrain could overturn the machine. Tall grass can hide obstacles.
Use slow speed. Choose a low speed so that you will not have to stop while on the slope.
Keep all movement on the slopes slow and gradual. Do not make sudden changes in speed or direction.
Avoid starting or stopping on a slope. If tires lose traction, disengage the blades and proceed slowly straight down the slope.
DO NOT
Do not turn on slopes unless necessary, and then, turn slowly and gradually downhill, if possible.
Do not mow near drop-off, ditches, or embankments. The mower could suddenly turn over if a wheel is over the edge of a cliff or ditch, or if an edge caves in.
Do not mow on wet grass. Reduced traction could cause sliding.
Do not try to stabilize the machine by putting your foot on the ground.
SERVICE
The operation of any mower can result in foreign objects thrown into the eyes, which can result in severe eye damage. Always wear safety glasses or eye shields while operating the mower or performing any adjustments or repairs. Wide vision safety mask over spectacles or standard safety glasses are recommended.
Keep nuts and bolts, especially blade attachment bolts, tight and keep equipment in good condition.
Never tamper with safety devices. Check there proper operation regularly.
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.

OPERATION

TIPS FOR IMPROVED BAGGING
Follow the mower operation instructions in you mower operator manual.
When operating the grass catcher on a lawn where grass and leaf bagging equipment has not been used, thatch and debris that has accumulated for long periods of time is picked up. The amount collected and the total time of operation may be greater than experienced with regular use of the grass catcher.
Always run throttle at full speed when bagging.
Select a speed low enough to give good mower cutting performance, good quality cut and good bagging performance.
NOTE: It may be necessary to overlap width of cut to suit conditions.
If grass is extremely tall, it should be mowed twice. The first time relatively high, the second time to desired height.
Use left hand side of mower for trimming.
Plastic trash bags (3.0 mil, 30 gallon) can be inserted inside grass catcher containers for ease of debris disposal. To remove the plastic trash bags when full:
a. Disengage blades, shift into neutral, engage
the parking brake and stop the engine. b. Unlatch and raise cover. c. Remove one container at a time by grasping
container handles and pulling toward the rear,
off of the tube rails. d. With the container resting on the ground, close
and secure the top of the plastic lawn bag. e. Tip the container on its side and slide the filled
bag from the container. f. Install a new plastic lawn bag with the edges
of the bag draped over upper lip of the
Container. g. Repeat for other containers. h. Reinstall containers making sure center
containers overlap at center supports. i. Close cover and secure latches over center
support tubes.
Avoid cutting wet grass or in the morning while the
dew is still heavy. Grass clippings collected under these conditions tend to be sticky and adhere to the walls of the flow path causing clogging.
If the grass catcher fails to pick up cut grass or leaves, it is an indication that clogging has occurred in the system or that the grass catcher containers are full.
a. Disengage blades, place motion control levers
in neutral position.
- Unlatch and raise cover.
- Slide out containers and dispose of
clippings.
- Replace containers, close cover, and latch. b. Unlatch chutes and check for clogging.
- Remove all debris in chute.
- Reassemble and latch chutes.
GENERAL RECOMMENDATIONS
Always observe safety rules when performing any maintenance. Before each use check for loose fasteners. Clean unit thoroughly after each use.
BLADE CARE
For best results mower blades must be kept sharp. Replace bent or damaged blades.
See BLADE CARE instructions in the mower operator manual.
STORAGE
When grass catcher is to be stored for a period of time, clean it thoroughly, remove all dirt, grass, leaves, etc. Store in a clean, dry place.
