Disengage the PTO to stop the broom (Figure 14).

Figure 14

If the machine has an optional Float Kit installed, move the switch to the FLOAT position to allow the broom to follow the contour of the ground (Figure 15). Move the switch to the normal operating position to control the broom using hydraulics.

Check the sweeping path of the bristles when you move the switch to the FLOAT position so that you limit the engagement of the bristles with the ground; refer to Checking the Sweeping Path.

Figure 15

1. Lower to normal operating position
2. Float position

A broom sweeps with the tips of its bristles. When you apply too much downward pressure, the broom no longer uses its tips; the broom is now working with the sides of the bristles. This limits the flicking action of the bristles and sweeping effectiveness, decreasing the service life of the broom.

1. Drive to a flat, dusty or snowy area and stop the machine.

2. Engage the broom, lower it to the ground to sweep away some snow or debris, and then raise it.

3. Disengage the broom and shut off the machine.

4. Wait for all moving parts to stop before leaving the operating position.

5. Make sure that the area swept equals the length of the broom and a maximum width of 51 to 102 mm (2 to 4 inches) as shown in Figure 16.

   Note: If you are using a Float Kit with the broom, the maximum width should be approximately 102 mm (4 inches).

   

   Figure 16

   2. Length of broom
   3. Swept area

6. If the width of the area swept is incorrect, adjust the machine A-frame stop as follows:

   1. Support the A-frame using blocks or a cylinder lock.

   2. Loosen the jam nut.

   3. Adjust the stop bolt until it holds the A-frame at the correct height above the machine frame (Figure 17).

      

      Figure 17

      1. Stop bolt
      2. Jam nut

   4. Tighten the jam nut to lock the bolt in position.

   5. Remove the blocks or cylinder lock and repeat the procedure to verify the correct sweeping path.

Use the kickstands to raise the broom off the ground when you are not using the machine, performing maintenance, or storing the broom. This eliminates unnecessary pressure on the bristles.

Important: Do not operate the machine with the kickstands down.

1. Park the machine on a level surface, disengage the PTO, move the motion-control levers to the NEUTRAL-LOCK position, and engage the parking brake.

2. Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.

3. Raise the A-frame and support it using blocks or a cylinder lock.

4. Lower the left, right, and rear kickstands (Figure 18).

Figure 18

1. Stay in the operating position and release the left traction-drive lever.

2. While engaging the broom, raise the broom above the ground.

If you cannot unclog the broom by lifting it into the air, clear the broom as follows:

1. Park the machine on a level surface, disengage the PTO, move the motion-control levers to the NEUTRAL-LOCK position, and engage the parking brake.

2. Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.

3. While wearing thickly-padded gloves, use caution to manually clear foreign objects out of the broom.

1. Park the machine on a level surface, disengage the PTO, move the motion-control levers to the NEUTRAL-LOCK position, and engage the parking brake.

2. Raise the A-frame and support it using blocks or a cylinder lock.

6. Remove the blocks or cylinder lock.

7. Disconnect the hoses from the low-flow assembly and plug them together.

8. Disconnect the hoses from the high-flow assembly and plug them together.

9. Plug the rubber caps into the quick-disconnect fittings on the machine.

10. Disengage the quick pin on the machine quick-attach assembly (Figure 7).

11. Use the machine hydraulics to lower the broom so that there is no weight on the machine quick-attach triangle.

12. Move the broom hoses away from the machine and back the machine out of the broom triangle.

13. Install the stop assembly as shown in Figure 19 or store it in a safe location.

• If the ground speed is too fast, debris will pile up in front of the broom, causing it to bulldoze instead of sweep. This can damage the broom.

• More pressure does not give a better sweep, but it will wear out the broom faster.

• A level broom lasts longer.

Use Toro Premium All Season Hydraulic Oil or SAE 20 oil.

1. Raise the broom all the way up using the hydraulic controls.

2. Lower the kickstands; refer to Using the Kickstands.

3. Remove the rubber plug on the chain housing and insert it into the housing with the cup side up (Figure 20).

   

   Figure 20

   1. Rubber plug

4. Fill the rubber plug with oil.

5. Start the machine and run it at low idle.

6. Engage the PTO and run the broom at low idle until the plug is out of oil.

7. Remove the plug and install it with the flat face up to prevent it from filling with debris during operation.

1. Loosen, but do not remove, the 3 mounting bolts on the broom motor until you can rotate the motor around the lower bolt (Figure 21).

   

   Figure 21

   2. Top mounting bolts
   3. Lower mounting bolt

2. Rotate the motor clockwise until the chain is tight, then rotate it counterclockwise 6 mm (1/4 inch) or 1 notch to allow some slack in the chain.

3. Torque the mounting bolts to 102 N∙m (75 ft-lb).

Replace the bristles when they are worn to a 33 cm (13 inch) diameter from the original 51 cm (20 inch) diameter. Check the condition of the wear plate when you replace the bristles (see Figure 25); if the wear plate is worn through, replace it.

Note: Replace all bristles at the same time; otherwise, a mix of old and new bristles will reduce performance.

1. Park the machine on a level surface, disengage the PTO, engage the parking brake, and move the motion-control levers outward to the NEUTRAL-LOCK position.
