INTRODUCTION  
Introduction  
Congratulations  
Thank you for purchasing a Husqvarna ride-on mower. This machine is built for the greatest efficiency and  
rapid mowing primarily of large areas. Controls in one place and a hydrostatic transmission regulated by  
steering controls also contribute to the machine’s performance.  
This manual is a valuable document. Following the instructions (use, service, maintenance, etc.) by all who  
operate this machine can considerably increase the lifespan of your machine and even increase its resale  
value. It is also very important to follow the instructions for the safety of you and others.  
If you sell your machine, be sure to give the operator’s manual to the new owner.  
The final chapter of this operator’s manual comprises a Service Journal. Ensure that service and repair  
work is documented. A well kept service journal reduces service costs for the season-based maintenance  
and affects the machine’s resale value. Take the operator’s manual along when the machine is left to the  
workshop for service.

1. Safety rules for USA  
These instructions are for your safety. Read them carefully.  
Safe operation practices for ride-on mowers  
IMPORTANT!  
This cutting machine is capable of amputating hands and feet and throwing objects. Failure to  
observe the following safety instructions could result in serious injury or death.  
Follow the manufacturer’s recommendations for  
wheel weights or counterweights to improve  
stability.  
Use extra care with attachments. These can  
change the stability of the machine.  
Keep all movement on the slopes slow and  
gradual. Do not make sudden changes in  
speed or direction.  
I. General operation  
1. Read, understand and follow all instructions in  
the manual and on the machine before  
starting.  
2. Only allow responsible adults, who are familiar  
with the instructions, to operate the machine.  
3. Clear the area of objects such as rocks, toys,  
wire, etc., which could be picked up and  
thrown by the blade.  
Avoid starting or stopping on a slope. If tires  
lose traction, disengage the blades and  
proceed slowly straight down the slope.  
4. Be sure the area is clear of other people  
before mowing. Stop the machine if anyone  
enters the area.  
DO NOT  
5. Never carry passengers.  
Do not turn on slopes unless necessary and  
then, turn slowly and gradually downhill, if  
possible.  
Do not mow near drop-offs, ditches or  
embandments. 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.  
6. Do not mow in reverse unless absolutely  
necessary. Always look down and behind  
before and while backing.  
7. Slow down before turning.  
8. Never leave a running machine unattended.  
Always turn off blades, set parking brake, stop  
engine and remove keys before dismounting.  
9. Turn off blades when not mowing.  
10. Mow only in daylight or good artificial light.  
11. Do not operate the machine while under the  
influence of alcohol or drugs.  
III. Children  
11. Watch for traffic when operating near or  
crossing roadways.  
Tragic accidents can occur if the operator is not  
alert to the presence of children. Children are often  
attracted to the machine and the mowing activity.  
Never assume that children will remain where you  
last saw them.  
1. Keep children out of the mowing area and  
under the watchful care of another responsible  
adult.  
13. Use extra care when loading or unloading the  
machine into a trailer or truck.  
14. Always wear eye protection when operating  
machine.  
II. Slope operation  
2. Be alert and turn machine off if children enter  
the area.  
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.  
3. Before and when backing, look behind and  
down for small children.  
4. Never carry children. They may fall off and be  
seriously injured or interfere with safe machine  
operation.  
DO  
Mow up and down slopes, 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.  
5. Never allow children to operate the machine.  
6. Use extra care when approaching blind  
corners, shrubs, trees or other objects that may  
obscure vision.  
Use slow speed. Choose a low gear so that  
you will not have to stop or shift while on the  
slope.

machine may relieve the manufacturer of liability for  
any resulting damage or injury.  
1. Tow only with a machine that has a hitch desig-  
ned for towing. Do not attach towed equipment  
except at the hitch point.  
Safe operation practices for Ride-On Mowers  
Before starting cutting operations, train different  
driving operations on an open ground without  
people nearby until you feel familiar with handling  
the equipment. This is particularly important if you  
have no or little prior experience of driving a  
vehicle.  
Data indicates that operators, age 60 years and  
above, are involved in a large percentage of riding  
mower-related injuries. These operators should  
evaluate their ability to operate the riding mower  
safely in order to protect themselves and others  
from serious injury.  
2. Follow the manufacturer´s recommendation for  
weight limits for towed equipment and towing  
on slopes.  
3. Never allowe children or others in or on towed  
equipment.  
4. On slopes, the weight of the towed equipment  
may cause loss of traction and loss of control.  
5. Travel slowly and allow extradistance to stop.  
Never carry children, even with the blades off. They  
may fall off and be seriously injured or interfere with  
safe machine operation.  
Intended use  
This machine is designed solely for cutting grass  
on conventional lawns and other cleared and  
leveled ground without obstacles, as rocks, stumps  
etc., and, in conjunction with accessories supplied
