Use only clean, fresh diesel fuel or biodiesel fuels with low (<500 ppm) or ultra low (<15 ppm) sulfur content. The minimum cetane rating should be 40. Purchase fuel in quantities that can be used within 180 days to ensure fuel freshness.

Use summer grade diesel fuel (No. 2-D) at temperatures above -7°C (20°F) and winter grade (No. 1-D or No. 1-D/2-D blend) below that temperature. Use of winter grade fuel at lower temperatures provides lower flash point and cold flow characteristics which eases starting and reduces fuel filter plugging.

Use of summer grade fuel above -7°C (20°F) contributes toward longer fuel pump life and increased power compared to winter grade fuel.

Important: Do not use kerosene or gasoline instead of diesel fuel. Failure to observe this caution damages the engine.

Biodiesel Ready

This machine can also use a biodiesel blended fuel of up to B20 (20% biodiesel, 80% petrodiesel). The petrodiesel portion should be low or ultra low sulfur. Observe the following precautions:

• The biodiesel portion of the fuel must meet specification ASTM D6751 or EN14214.

• The blended fuel composition should meet ASTM D975 or EN590.

• Painted surfaces may be damaged by biodiesel blends.

• Use B5 (biodiesel content of 5%) or lesser blends in cold weather.

• Monitor seals, hoses, gaskets in contact with fuel as they may be degraded over time.

• Fuel filter plugging may be expected for a time after converting to biodiesel blended.

• Contact your distributor if you wish for more information on biodiesel.

1. Move all controls to NEUTRAL, engage the parking brake, move the throttle to the low idle position and allow the engine to reach low idle speed.

   Important: Allow the engine to idle for 5 minutes before shutting it off after a full load operation. Failure to do so may lead to trouble on a turbocharged engine.

2. Turn the key to the OFF position and remove it from the switch.

The turf-compensation spring (Figure 51) transfers the weight from the front roller to the rear roller. This helps to reduce a wave pattern in the turf, also known as marcelling or bobbing.

Important: Make spring adjustments with the cutting unit mounted to the traction unit, pointing straight ahead, and lowered to the shop floor.

1. Make sure that the hairpin is installed in the rear hole in the spring rod (Figure 51).

   Note: When servicing the cutting unit, move the hairpin to the spring-rod hole next to the turf-compensation spring.

   

   Figure 51

   1. Turf-compensation spring
   2. Hairpin
   3. Spring rod
   4. Hex nuts

2. Tighten the hex nuts on the front end of the spring rod until the compressed length of the spring is 15.9 cm (6.25 inches); refer to Figure 51.

   Note: When operating on rough terrain decrease the spring length by 13 mm (1/2 inch). Ground following will be slightly decreased.

   Note: The turf compensation setting will need to be reset if the HOC setting or the Aggressiveness of Cut setting is changed.

You can adjust the amount of counterbalance force applied to the rear cutting-units to help compensate for different turf conditions, and to maintain a uniform height of cut in rough conditions or in areas of thatch buildup.

You adjust counterbalance force of each torsion spring to 1 of 4 settings. Each increment increases or decreases the counterbalance force on the cutting unit by 2.3 kg (5 lb). You can position the springs at the back side of the first spring actuator to remove all counterbalance (fourth position).

Note: To remove all counterbalance force, position the long leg of the torsion spring above the shouldered stud.

1. Park the machine on a level surface, lower the cutting units, shut off the engine, engage the parking brake, and remove the key.

2. Insert the long end of the counterbalance spring into a tube or similar object, and pivot the spring around the shouldered stud to the desired position (Figure 52).
