OPERATING INSTRUCTIONS

GENERAL INFORMATION

This manual will assist you in the safe operation and proper maintenance of your Husqvarna equipment. Read it thoroughly before attempting to operate the machine. Do not hesitate to call your dealer or Husqvarna if additional information is required.

The following safety symbols are used throughout the manual to alert you to information about unsafe actions or situations:

DANGER: indicates immediate hazards that may result in severe injury or death.

WARNING: indicates unsafe actions or situations that may cause severe injury, death and or major equipment or property damage.

CAUTION: indicates unsafe actions or situations that may cause injury and/or minor equipment or property damage.

This equipment should not be modified without the manufacturer’s prior written authorization. Doing so without our written permission may not only affect the equipments performance and durability, but also create safety hazards for the operator and the surroundings. Warranty will be void if changes are made to the equipment without the manufacturer’s prior written authorization.

SAFETY PROCEDURES

DO:

• Only start with shift lever in neutral.

• Read all maintenance and service instructions before attempting work.

• Follow engine manufacturer operating and maintenance instructions.

• Inspect area to be cut and remove rocks, wire, string and other objects that might present hazard

before starting.

• Identify and mark all in ground objects to be avoided, such as sprinkler heads, stakes, water

valves, clothes line anchors, etc.

• This machine was designed for sod cutting only. It is not intended for any other use.

DO NOT:

• Do not start in gear.

• Do not cut at high transport speeds.

• Do not use on any surface other than grass.

• Do not operate on slopes exceeding 35% grade.

• Do not place hands or feet near moving or rotating parts.

• Do not run engine in an unventilated area.

• Do not shift with throttle engaged.

• Do not run engine while servicing. Remove spark plug wire before servicing.

• Do not remove guards when operating.

• Do not lift this 330 lb. machine.

OPERATOR’S TIPS

• To engage reverse gear you may have to push the machine back and forth while pulling the shift

lever.

• Stop before shifting gears.

• Cut going down hill on unlevel ground.

• End cuts by pushing the blade engagement lever forward while still holding the throttle to cut the

end of the sod strip as the blade rises.

• Soil conditions will effect cutting depth Readjusting the blade depth may be required as you move

from hard soil to soft or moist soil conditions.

4

OPERATING INSTRUCTIONS

• Do not attempt sharp turns while cutting.

• Should I water before cutting?

It is usually not necessary to water before cutting. In extreme conditions, such as clay soil that is very compacted, a simple test as follows will determine if you need to water before cutting. Use a garden hand spade, weed tool, or even a large screwdriver to test the ground’s hardness. You should be able to push the tool into the ground 2 to 3 inches with little effort.

If you are unable to do so, then watering may be advisable. Watering the day before should give sufficient time for the soil to absorb the moisture. Use your hand tool to gauge the effectiveness of your watering. Allow the grass to dry before cutting to provide adequate traction for sod cutting.

OPERATING ON HILLS

WARNING - DO NOT operate on hills exceeding 35% grade to prevent machine from rolling over.

Please be aware that when operating on hills, you may experience:

• The need to exert greater effort to steer and maintain the balance of the machine.

• Uneven cutting depth, when operating across a hill. The shifted center of gravity may cause the

downhill side of the blade to penetrate to the maximum depth, while the uphill side may not.

With these factors in mind, you may find it more effective to:

• Operate the machine cutting down rather than across hills. You will achieve even cutting depth, and

enhance stability.

• Avoid hill side turns. Back up hills in reverse gear, then cut, going down.

BEFORE YOU START

• Read and understand this manual.

• Be sure engine oil is at engine manufacturer’s recommended level. (Refer to engine

manufacturer’s manual.)

• Put the sod cutter into neutral before starting.

• Place blade in transport position before starting.

TRANSPORTING

• Push the blade engagement lever forward to raise the blade.

• Select the desired gear (slow-fast-reverse).

• Pull the throttle while maintaining a firm grip on the handlebar.

• To make turns, push down on the handlebar to do “a wheelie,” then turn.

• Load into truck or trailer by driving up ramps in low gear. DO NOT LIFT! This 330lb machine is not

intended to be lifted by hand.

SOD CUTTING See Figure - Page 3

1. Position the sod cutter at your starting point with the blade out of the ground.

2. Pull the blade engagement lever toward you with one hand while lifting the handlebar with the

other hand.

3. Place the shift lever in slow gear (turtle icon).

4. Pull the throttle while maintaining a slight down pressure on the handlebar and cut a short

distance, then stop. Put shift lever in neutral.

5. Lift the edge of the sod to check the cut depth.

6. To change the depth, push the blade engagement lever forward, unlock the depth lock knob (red

knob), and turn the depth adjustment knob clockwise for less depth, or counterclockwise for

more depth; then lock the depth lock knob.

7. Repeat steps 2 through 6 as necessary to set depth of cut.

8. End cuts by pushing the blade engagement lever forward while holding the throttle to cut the end

of the sod strip as the blade exits the ground.
