Attaching the Finish Drag Mat (Optional, Sold Separately)

If you plan to install the finish drag mat, do so before installing the nails. Refer to the finish drag mat Operator’s Manual.

Note: You can install the finish drag mat later, but you will need to remove various components of the nail drag to do so.

Installing the Nails

Before you install the nails, attach the nail drag to the machine so that you can raise it with the attachment lift; refer to Attaching the Nail Drag to the Machine.

  1. Remove the top drawbar bolts, locknuts, and spacers.

  2. Install the nail plate onto the clevis pins.

  3. Install the top drawbar bolts, locknuts, and spacers, and tighten them until they are secure.

  4. Start the machine, and raise the attachment lift so that the nail drag is up off the ground.

  5. Insert the nails down through the nail plate and the bottom plate (Figure 9).

Operation

Installing and Removing the Weights

Always ensure that your machine has the appropriate number of weights.

Refer to the following table for how many weights are required on the front of the machine:

AttachmentNumber of weights required
Flex tooth rake4
Nail drag6
Nail drag with finish drag mat8

  1. Remove the 2 bolts and 2 nuts securing the existing weights on the front of the machine (Figure 11).

    Note: If the machine is equipped with the light kit, remove the nut and the bolt securing the front light to the machine. Retain all of the parts; refer to the Light Kit Installation Instructions.

    g023729

    Figure 11

  2. Add or remove weights as necessary.

  3. Secure the weights with the 2 bolts and the 2 nuts.

    The Finish Drag Mat includes 2 longer bolts to accommodate the additional weights that it requires.

    Note: If the machine is equipped with the light kit, install the front light by inserting the bolt through the weights and securing it with the nut; refer to the Light Kit Installation Instructions.

Attaching the Nail Drag to the Machine

Connecting the Chains to the Attachment Lift

  1. Position the drawbar under the machine.

  2. Install a shackle on the end of each lift chain.

  3. Align each shackle to the appropriate side of the attachment lift on the machine (Figure 12).

    g023744

    Figure 12

  4. Secure each shackle with a flange locknut (5/16 inch) and a bolt (5/16 x 2-1/2 inches).

    Note: Ensure that the threads of each bolt contact the nylon insert of the flange locknut, and that each shackle pivots freely.

    Important: Ensure that the chains are not twisted inside the convoluted covering.

Connecting the Drawbar to the Frame Hitch

  1. Align the rod end of the drawbar to the frame hitch (Figure 13).

    5. Rod end

  2. Align a spacer on each side of the rod end, and insert the bolt (3/4 x 4-1/2 inches) through the frame hitch, the rod end, and the spacers.

  3. Secure the bolt with the locknut (3/4 inch) torqued to 163 to 217 N-m (120 to 160 ft-lb).

Connecting the Frame Bracket

  1. Remove the nut and the bolt securing the muffler shield to the back of the machine (Figure 14).

    g023746

    Figure 14

    Bracket shown without chain, for clarity

  2. Align the bolt holes in the frame bracket with the bolt holes in the frame.

    Note: Ensure that the chains are crossed as shown in Figure 15.

    g023956

    Figure 15

  3. Secure the frame bracket with 4 bolts (5/16 x 1 inch) and 4 flange locknuts (5/16 inch); refer to Figure 14.

Removing the Nail Drag 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.

Stowing the Groomer

If you want to use the nail drag without using the groomer, you can raise it up and out of the way.

  1. Remove the clevis pins (Figure 16).

    g023963

    Figure 16

    1. Clevis pin (2)
    2. Groomer in stowed position

  2. Tilt the groomer upward, and insert the clevis pins to secure it into that position.

Using the Back Blade

Driving backward while the groomer is in the lowered position pivots the groomer and the blade downward, and changes the angle of the blade. You can use the blade to push the material and fill voids and low spots. Push the material in front of the low spot, and simply drive forward over that area again to level the material.

Adjusting the Depth

Adjust the depth to suit your grooming conditions and preferences. You can also adjust the depth to compensate for worn nails.

Note: If you notice that the nail drag is carrying too much material, increase the depth to allow more material to flow through the nail drag.

  1. Start the machine, and raise the attachment lift so that the nail drag is up off the ground.

  2. Remove the lynch pins.

  3. Set the depth to suit your grooming conditions and preferences.

    • To increase the depth, squeeze the top plates and the bottom plate together, so that the springs compress.

    • To decrease the depth, allow the springs to push the top plates and the bottom plate apart.

    g023964

    Figure 17

    1. Less depth
    2. More depth

  4. Install the lynch pins into the desired holes in the clevis pins.

    Note: Set all of the lynch pins to the same depth.

Operating Tips

  • When using the back blade to fill voids, push the material so that it is just in front of the void. This allows the nail drag and the groomer to fill the void more completely when leveling the surface.

  • To increase the usable life of the groomer, you can remove it, flip it over, and install it again.

Maintenance

Replacing the Nails

  1. Start the machine, and raise the attachment lift so that the nail drag is up off the ground.

  2. Remove the lynch pins from the 8 clevis pins securing the top plates to the nail plate and the bottom plate (Figure 18).

    Note: Retain the lynch pins for installing the top plates.

    g023747

    Figure 18

  3. Remove the top plates.

    Note: You may need to loosen the top nuts and bolts securing the drawbar to the nail drag assembly; refer to Figure 4.

  4. Remove the old nails.

  5. Insert the new nails down through the nail plate and the bottom plate.

  6. Install the top plates and secure them with the lynch pins.

  7. If you loosened the top nuts and bolts securing the drawbar to the nail drag assembly, tighten them.

Cleaning the Nail Drag

Keep the nail drag clean. Excessive soil buildup increases the attachment weight and may affect the handling of the machine.

Troubleshooting

ProblemPossible CauseCorrective Action
The appearance of the groomed surface is unacceptable.
  1. The nail depth is not correct.
  2. The desired appearance is not possible with the standard configuration.
  3. The machine speed is too fast or too slow.
  1. Adjust the nail depth or remove some nails if necessary.
  2. Install the optional drag mat kit (sold separately).
  3. Adjust the machine speed, or install the optional speed limiter kit (sold separately).
The nail drag contacts the tires.
  1. The stop chains are not assembled properly.
  1. Ensure that the stop chains are crossed and that the bolt securing the chains is installed in the 6th link from the drawbar.
The nail drag is off center when grooming in a straight line (dog tracking).
  1. A lift chain is twisted inside the protective covering.
  1. Remove the shackle, eliminate the twist in the chain, and install the shackle again.
There is material buildup in front of the attachment.
  1. The material is too wet.
  2. More clearance is required to allow the material to flow through the nail drag.
  1. Allow the material to dry before grooming.
  2. Increase the nail depth or modify the pattern by removing some nails.
