Operation
Read, understand, and follow all instructions in the manual and on the machine before starting:
•How to operate all controls
•The functions of all controls
•How to stop in an emergency
•Braking and steering characteristics
•Turning radius and clearances
ALWAYS keep protective structures, guards, and panels in good repair, in place and securely fastened.
Complete a walk-around inspection of the unit and work area.
ALWAYS disengage PTO, stop unit and engine, remove key, engage parking brake and allow moving parts to stop before leaving operator’s position.
ALWAYS remove key to prevent unauthorized use.
Check for weak spots on dock, ramps or floors. Avoid uneven work areas and rough terrain.
Dust, smoke, fog, etc. can reduce vision and cause an accident. Mow only in daylight or good artificial light.
Watch for traffic when operating near or crossing roadways.
7
Only allow responsible adults who are trained and familiar with the instructions to operate the machine.
Training includes actual operation.
Clear the area of objects such as tree branches, rocks, toys, wire, etc., which could be picked up and thrown by the blades. Tall grass can hide obstacles.
Be sure the area is clear of people before mowing. Stop machine if anyone enters the area.
Use extra care when approaching blind corners, shrubs, trees, or other objects that may obscure vision.
Watch for holes, ruts, or bumps. Uneven terrain could overturn the machine.
Do not mow in reverse unless absolutely necessary. Always look down and behind before and while backing.
Be aware of the mower discharge direction and do not point it at anyone. Always stand clear of discharge area.
DO NOT operate at too fast a rate.
DO NOT change engine governor settings or over-speed engine. Slow down before turning.
Disengage PTO when attachment is not in use. ALWAYS turn off power to attachment when transporting, crossing driveways, etc.
Stop engine before removing grass catcher or unclogging chute.
Do not operate mower unless bagger is attached or guards are in operating position.
If you cannot back up a slope or you feel uneasy on it, do not mow it.
Mow up and down slopes, not across them.
Use slow speed on any slope. Choose a low gear so that you will not have to stop or shift while on the slope.
Follow the manufacturer’s recommendations for wheel weights or counterweights to improve stability.
Use extra care with grass catchers or other attachments. These can change the stability of the machine. Use only approved hitch points.
Keep all movements on the slope slow and gradual. Do not make sudden changes in speed or direction.
Avoid starting or stopping on the slope. If tires lose traction, disengage the blades and proceed slowly straight down the slope.
Do not mow near dropoffs, 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.
Do not use grass catcher on steep slopes.
Do not operate on slopes over 10˚ maximum.
