Phone: (1-800-935-2967).

PROTECTION FOR CHILDREN

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 a responsible adult.

2.DO NOT allow children in yard when machine is operated (even with the blades OFF).

3.DO NOT allow children or others to ride on machine, attachments or towed equipment (even with the blades OFF). They may fall and be seriously injured.

4.DO NOT allow pre-teenage children to operate machine. Local regulations may restrict the age of the operator.

5.ALLOW only adults or responsible teenagers with mature judgment under close adult supervision to operate machine.

6.DO NOT operate blades in reverse. STOP BLADES. LOOK and SEE behind and down for children, pets and hazards before and while backing.

7.USE EXTRA CARE when approaching blind corners, shrubs, trees, or other objects that may obscure vision.

PROTECTION AGAINST TIPOVERS

This machine is equipped with a roll bar protective structure, which, when used properly, can offer additional security to the operator in the event of a tip-over accident. For proper protection, the roll bar must be raised and locked and the lap-style seat belt must be worn at all times.

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 the slope, DO NOT mow it. Use extra care with grass catchers or other attachments; these and turf conditions affect the handling and the stability of the machine.

1.DO NOT operate machine on slopes exceeding 15 degrees (27% grade).

2.Exercise EXTREME CAUTION on slopes above 10 degrees (18% grade). Turn blades OFF when traveling uphill. Use a slow speed and avoid sudden or sharp turns.

PROTECTION AGAINST TIPOVERS

(Continued From Previous Column)

3.DO NOT operate machine back and forth across face of slopes. Operate up and down. Practice on slopes with blades off.

4.AVOID starting, stopping or turning on slopes. If machine stops going uphill or tires lose traction, turn blades OFF and back slowly straight down the slope.

5.STAY ALERT for holes and other hidden hazards. Tall grass can hide obstacles. Keep away from ditches, washouts, culverts, fences and protruding objects.

6.DO NOT operate machine near drop offs, ditches, embankments, washouts, culverts, fences and protruding objects. KEEP A SAFE DISTANCE (at least 3 feet) away from edge of ditches and other drop offs. The machine could turn over if an edge caves in.

7.Always begin forward motion slowly and with caution.

8.Use weights or a weighted load carrier in accordance with instructions supplied with a grass catcher. DO NOT operate machine on slopes exceeding 10 degrees (18% grade) when equipped with grass catcher.

9.DO NOT put your foot on the ground to try to stabilize the machine.

10.DO NOT operate machine on wet grass. Reduced traction could cause sliding.

11.Choose a low enough ground speed setting so that you will not have to stop or shift on a slope. Tires may lose traction on slopes even though the brakes are functioning properly.

12.DO NOT operate machine under any condition where traction, steering or stability is doubtful.

13.Always keep machine in gear when going down slopes. DO NOT shift to neutral (or actuate hydro roll release) and coast downhill.

14.DO NOT remove or modify any part of the roll bar protective structure. Do not fold the roll bar unless absolutely necessary. There is no roll-over protection when the roll bar is folded.

15.Operator must be properly seated at all times, and must wear seat belt, snuggly fastened, at all times except when roll bar is folded.

16.DO NOT exceed the machine weight rating specified on the roll bar protective structure’s identification plate.

STATEMENT OF USAGE

This manual contains safety information to make you aware of the hazards and risks associated with the machine and how to avoid them. This machine is designed and intended to be used and maintained according to the manual and operated by trained professionals for finish cutting of established lawns and is not intended for any other purpose. It is important that you read and understand these instructions thoroughly before attempting to start or operate this equipment.

ENGINE POWER RATING INFORMATION

The gross power rating labels for individual gas engine models meet or exceed SAE (Society of Automotive Engineers) code J1940 (Small Engine Power & Torque Rating Procedure) and rating performance has been obtained and corrected in accordance with SAE J1995 (Revision 2002-05). Actual gross engine power may be lower and is affected by, but not limited to, ambient operating conditions and engine to engine variability. Given both the wide array of products on which engines are placed, and the variety of environmental issues applicable to operating the equipment, the gas engine will not develop the rated gross power when used in a given piece of power equipment (actual “on-site” or net horsepower). This difference is due to a variety of factors including, but not limited to, accessories (air cleaner, exhaust, charging, cooling, carburetor, fuel pump, etc.), application limitations, ambient operating conditions (temperature, humidity, altitude), and engine to engine variability.

3.2STARTING & STOPPING - ENGINE, BLADES, PARKING BRAKE

This machine is equipped with dual hydrostatic wheel drive transmissions. Each hydro pump is controlled by a separate motion control lever. The left lever controls the left wheel drive hydro pump and the right lever controls the right wheel drive hydro pump. These levers control the direction of motion, Forward & Reverse, and the speed of motion. Move both levers forward to propel the machine forward. Move both levers rearward to propel the machine in reverse. The speed of motion is continuously variable from neutral (zero) to the maximum. Moving the levers farther from the neutral position will cause the speed of motion to increase. To turn, move the lever on the side to which you want to turn slightly rearward of the other lever. Move levers slowly and carefully. DO NOT make sudden changes in speed or direction. Always slow machine motion before turning. To stop the motion of the machine, bring both motion control levers to the neutral position. Engage parking brake.

Section 53 - ADJUSTMENTSOPERAINGINSTRUCTIONS& REPAIR

5.11HYDRAULIC SYSTEM, PURGING

After replacing or repairing hydraulic system components, one or both of the wheel drives may not pull properly. This is likely to be caused by air entrapped in the system. If you experience a pulling issue after completing repairs, perform the following procedure to purge the air from one or both of the hydraulic drive systems.

IMPORTANT: WHEN REPLACING THE HYDRAULIC FLUID FILTERS, PRE-FILL WITH OIL (SAE 20W50 API SL) BEFORE INSTALLING. PRE-FILLING THE FILTERS WITH OIL WILL REDUCE OR POSSIBLY ELIMINATE THE NEED TO PURGE THE SYSTEM OF ENTRAPPED AIR

1.Locate hydraulic reservoirs underneath operator's seat. After thoroughly cleaning the area around the top of each reservoir, remove filler cap. Bring fluid to proper level (1 ½" below the top of the filler neck). With engine off, add SAE 20W50 automotive oil. See Figure

NOTE: In order to raise operator set to access reservoirs, seat must be in rearmost position.

2.Open pressure relief valve on hydraulic pump, turning counter clockwise 2 full turns. See Figure 3.3.

3.Carefully raise the rear of the machine so the wheels are off of the ground. Securely block the machine to prevent it from falling.

4.While seated in the operator's position, start the engine. Place engine speed control in FAST position.

5.Release parking brake and move motion control levers out of the neutral lock position.

6.Slowly move motion control levers to the full forward and then to the full rearward positions. Repeat this process 6 times.

7.Stop engine and wait for all rotation to stop before leaving the operator's position.

8.Close pressure relief valve on hydraulic pump, turning clockwise. Tighten snuggly.

9.With pressure relief valve closed, repeat Steps 4 thru 7.

10.Remove blocks and lower rear of machine.

11.Check fluid level in reservoir. Add SAE 20W50 automotive oil as required to bring fluid level to 1-½" from top of filler neck. Do Not over fill.

12.Install and tighten filler cap.
