Adjusting the Pivot Stop Bolts

  1. Pivot the rake to 1 side. The stop bolt should contact the drawbar when the rake is 51 mm (2 inches) away from the tire (Figure 18).

    If there is 51 mm (2 inches) of clearance between the rake and the tire, no adjustment is necessary.

    g023918

    Figure 18

    1. 51 mm (2 inches)

  2. Determine whether there is not enough clearance or too much clearance between the tire and the rake.

    • If there is not enough clearance, loosen the flange locknut.

    • If there is too much clearance, loosen the jam nut.

    Note: Use a wrench on the square neck of the bolt to prevent the bolt from spinning.

  3. When the stop bolt is in position so that there is 51 mm (2 inches) of clearance between the rake and the tire, tighten the appropriate nut.

    • If you loosened the flange locknut, tighten the jam nut now.

    • If you loosened the jam nut, tighten the flange locknut now.

    Note: Use a wrench on the square neck of the bolt to prevent the bolt from spinning.

  4. Repeat the procedure for the other stop bolt.

  5. Ensure that the rake does not contact the tires throughout the range of motion.

Inspecting the Raking Pattern and Adjusting the Lift-in-turn System

Inspecting the Raking Pattern

  1. Ensure that the tires are inflated to 48 kPa (7 psi).

  2. Drive the machine to a sand trap—with a flat bottom, if possible.

  3. With the rake in the lowered position, turn the machine to the left while driving, so that the rake is fully pivoted.

  4. Stop the machine, stop the engine, set the parking brake, remove the key, and wait for all moving parts to stop.

  5. Get off the machine, and inspect the left-hand side of the raking path in the sand.

    Note: The rake should groom over the tire tracks, but it should not contact the sand beyond the tire tracks. If the raking path is not correct, refer to Adjusting the Lift-in-turn System.

  6. Repeat the procedure for the right-hand side of the rake.

Adjusting the Lift-in-turn System

  1. Complete steps 1 through 5 in Inspecting the Raking Pattern.

  2. Pivot the rake fully to 1 side.

  3. On the inside of the turn (for example, the left-hand side if the rake is pivoted to the left), determine whether the rake contacts the sand too much and grooms beyond the tire tracks, or does not contact the sand enough to groom over the tire tracks.

  4. Note the hole to which the top of the cable is mounted.

  5. Remove the shoulder bolt and the flange nut, and move the end of the cable to the appropriate hole.

    • If the rake contacts the sand too much and grooms beyond the tire tracks, move the top of the cable to a hole closer to the center of the boom.

      g023805

      Figure 20

    • If the rake does not contact the sand enough to groom over the tire tracks, move the top of the cable to a hole further away from the center of the boom.

  6. Secure the cable with the shoulder bolt and the flange nut.

    Note: To decrease the chance of binding, ensure that the end of the cable is positioned as shown in Figure 20.

  7. Repeat the procedure for the other side.

Adjusting the Rake Pitch

You can adjust the pitch of the rake to increase or decrease the amount of material agitation. If the rake edge is angled forward (Figure 21), toward the machine, the rake will carry more material and agitate the material at a deeper level. If the rake edge is angled backward (Figure 23), away from the machine, the rake will carry less material and agitate the material at a shallower level.

  2. Loosen the rear nuts and bolts.

  3. Adjust the rake to the preferred pitch until the appropriate holes are aligned.

    Note: The middle position uses the holes closer to the rear bolts. The other 2 positions use holes farther away from the rear bolts.

  4. Install the bolts into the holes, and secure them with the nuts.

  5. Tighten the nuts on the front and rear bolts.

Raising and Lowering the Rake

To raise and lower the rake, use the attachment switch on the right control handle of the machine.

Press upward on the switch to raise the rake, and press downward on the switch to lower the rake; refer to the machine Operator’s Manual.

Removing the Rake from the Machine

Warning

If you drive the machine without an attachment installed, it can tip over and injure someone or damage property.

Do not drive the machine without a Toro-approved attachment installed.

  1. Disconnect the drawbar from the frame hitch.

  2. Disconnect the shackles from the attachment lift.

  3. Remove the frame bracket from the rear of the machine.

Raking a Sand Trap

Read this entire section on raking before raking a sand trap. There are many conditions that will determine the adjustments necessary. The texture and depth of the sand, moisture content, weeds, and the amount of compaction are all factors that can vary from course to course, or even from trap to trap on the same course. Make the adjustments on the rake for optimum results in your particular area.

Learning How to Rake

Practice raking in a large and level trap on the course. Practice starting and stopping, turning, raising and lowering the rake, entering and leaving the trap, etc. Practice at a moderate engine speed and a slow ground speed. This training will help the operator to gain confidence in the performance of the machine.

The recommended pattern for raking a trap is shown in Figure 25. This pattern avoids unnecessary overlap, keeps compaction to a minimum, and leaves a neat, attractive pattern on the sand. This is the most efficient raking method, however, it is important to vary the raking pattern regularly to reduce the chance of creating a washboard effect.

g003409

Figure 25

  1. Enter a trap straight into the long dimension in a level area.
  2. Exit a trap at a right angle in a level area.

Enter the trap straight into the long dimension, where the bank is the least steep. Drive through the center of the trap almost to the end, turn to either direction as sharp as you can, and come back right next to the first pass. Spiral outward as shown in Figure 25, and leave the trap at a right angle in a level area.

Leave steep, short banks and small pockets for touch-up with a hand rake.

Entering and Leaving the Trap

When entering the trap, do not lower the rake until it is over the sand. This avoids cutting the turf or dragging grass clippings or other debris into the trap. Lower the rake while the machine is moving.

When leaving the trap, start raising the rake when the front wheel leaves the trap. As the machine moves out, the rake will be lifting and will not drag sand out onto the grass.

Through experience and practice, the operator will soon understand the required timing for entering and leaving the trap properly.
