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.)  
can considerably increase the lifespan of your machine and even increase its resale value.  
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.

SAFETY INSTRUCTIONS  
Driving on Slopes  
Driving on slopes is one of the operations  
where the risk is greatest that the driver will  
lose control or the machine will tip over, which  
can result in serious injury or death. All  
slopes require extra caution. If you cannot  
reverse up a slope or if you feel unsure,  
do not mow the slope.  
Do as follows  
Remove obstacles such as stones,  
tree branches, etc.  
Watch out for and avoid driving over  
furrows, holes, and bumps. On uneven  
terrain, the machine can tip more easily.  
Long grass can hide obstacles.  
6003-004  
Mow up and down, not side-to-side  
Mow up and down, not side-to-side.  
Drive evenly and slowly. Use small  
movements of the steering controls.  
Be extra cautious with any additional equipment, which can alter the machine’s stability.  
If the machine stops while going uphill, disengage blades and back down slowly.  
Do not  
Do not make sudden changes in speed or direction.  
Do not drive the mower on terrain that slopes more than 10°.  
Do not mow near verges, ditches, or banks. The machine can suddenly spin around if a wheel goes  
over the edge of a drop or ditch, or if an edge gives way.  
Do not mow wet grass. It is slippery, and  
the tires can lose their grip, so that the  
machine slides.  
Do not try to stabilize the machine by  
putting a foot on the ground.  
Do not drive near verges or ditches  
when cleaning the machine.  
Do not turn on slopes unless necessary,  
and then, turn slowly and gradually  
downhill, if possible.  
Avoid starting or stopping on a slope. If  
the tires begin to slip, shut down the  
blades and drive slowly straight down the  
slope.
