INTRODUCTION

Introduction

Congratulations

Thank you for purchasing a Husqvarna Rider. Husqvarna Riders have been designed according to a unique concept with a front mounted cutting unit and patented rear wheel steering. The Rider is built to give maximum efﬁciency even in small and conﬁned areas. Collected controls and a hydrostatic transmission controlled by pedals also contribute to the machine’s performance.

This operator’s manual is a valuable document. Following the instructions (use, service, maintenance, etc.) can considerably increase the life span of your machine and even increase its resale value.

When you sell your Rider, make 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 Rider is left to the workshop for service.

SAFETY INSTRUCTIONS

Driving on slopes

Driving on slopes is one of the operations where the risk of the driver losing control of the machine or of it overturning is the greatest; this can result in serious injury or death. All slopes demand extra care. If you cannot reverse up a slope or if you feel unsure, do not mow it.

IMPORTANT INFORMATION

Do not drive down slopes with the unit raised.

Do as follows

•Remove obstacles such as stones, tree branches, etc.

•Mow up and down, not side-to-side.

•Never drive the machine on terrain that slopes more than 15°.

•Avoid starting or stopping on a slope. If the tyres start to slip, stop the blades and drive slowly down the slope.

•Always drive evenly and slowly on slopes.

•Make no sudden changes in speed or direction.

•Avoid unnecessary turns on slopes, and if it proves necessary, turn slowly and gradually downward,

if possible.

•Watch out for and avoid driving over furrows, holes, and bumps. It is easier for the machine to overturn on uneven ground. Tall grass can hide obstacles.

•Drive slowly. Do not turn the wheel sharply.

•Be extra cautious with any additional equipment, which can alter the machine’s stability.

•Do not mow near verges, ditches, or banks. The machine can suddenly overturn if one wheel comes over the edge of a steep slope or a ditch, or if an edge gives way.

•Do not mow wet grass. It is slippery, and tyres can lose their grip so that the machine skids.

•Try not to stabilise the machine by putting a foot on the ground.

•When cleaning the chassis, the machine may never be driven near verges or ditches.

•Follow the manufacturer’s recommendations regarding wheel weights or counterbalance weights to increase machine stability.

IMPORTANT INFORMATION

Wheel weights ﬁtted on the rear wheels are recommended when driving on slopes for safer steering and improved manoeuvrability. Consult your dealer concerning the use of wheel weights if you are unsure.

Mowing tips

WARNING!

Clear the lawn of stones and other objects that can be thrown out by the blades.

•Localise and mark rocks and other ﬁxed objects in order to avoid collisions.

6007-212

Mowing patterns

• Begin with a high cutting height and reduce it until the desired mowing result is attained.

• The best mowing result will be obtained at a high engine speed (the blades rotate rapidly) and low speed (the Rider moves slowly). If the grass is not too long and thick the driving speed can be increased without signiﬁcantly impairing the mowing result.

	WARNING!
	Never drive the Rider on terrain that
	slopes more than 15°. Mow upwards and
	downwards on slopes, never sideways.
	Avoid sudden changes in direction.
	• The ﬁnest lawns are obtained by mowing often.
	Mowing will be more even and the clippings will be	MAX 15
	more evenly distributed across the area. The overall	MAX 15
	more evenly distributed across the area. The overall
	mowing time will not be longer as higher driving
	speeds can be selected without impairing the	6016-104
	speeds can be selected without impairing the
	mowing result.

•Avoid mowing wet lawns. The mowing result will be poorer as the wheels will sink into the soft lawn.

•Hose beneath the cutting unit with water after each use. When cleaning, the cutting unit should be moved into the service position.

•It is important to mow frequently when mowing with the mulching function.
