6. Slide the arms on the roller into the arms on the cultivator and connect them with the drift pins (Figure 3).

7. Secure the drift pins with the attached snap-ring clevis pins.

Refer to the Operator’s Manual for the traction unit for the installation and removal procedure.

Important: Before installing the attachment, position the machine on a level surface, ensure that the mount plates are free of any dirt or debris, and ensure that the pins rotate freely. If the pins do not rotate freely, grease them.

Note: Always use the traction unit to lift and move the attachment.

To use the cultivator as a tiller without the grader or roller, or to perform various adjustments and maintenance procedures, remove the roller and grader as follows:

1. Park the machine on a level surface, lower the attachment, tilt the attachment to raise the roller off of the ground, and engage the parking brake (if equipped).

2. Shut off the engine and remove the key

3. Remove the drift pins from the arms of the cultivator (Figure 5).

4. Pull the roller off the cultivator (Figure 5).

5. Store the pins in the arms of the roller for future use.

Note: To install the roller, refer to Installing the Roller.

Set the dig depth of the cultivator according to the work you are performing up to 13.9 cm (5-1/2 inches). The depth of cut is determined by the position of the roller. You can move the roller up and down by changing the mounting location of the arms on the cultivator as follows:

1. Remove the roller from the cultivator; refer to Removing the Roller.

2. Remove the bolts securing the arms to the cultivator (Figure 6).

   

   Figure 6

3. Move the arms to the set of holes corresponding to the desired depth (Figure 6).

   • Move the arms up to set the digging depth deeper

   • Move the arms down to set the digging depth shallower.

4. Secure the arms using the bolts and nuts removed previously.

5. Install the roller.

You can adjust the grader blade that sits just behind the roller to give the desired finish. Typically, you should adjust it so that the edge of the blade is just slightly higher than the bottom of the roller.

1. Park the machine on a level surface, lower the attachment, tilt the attachment to raise the roller off of the ground, and engage the parking brake (if equipped).

2. Shut off the engine and remove the key

3. Remove the drift pins from the grader-blade mounting posts (Figure 7).

   4. Grader-blade mounting post

4. Slide the grader blade up or down to the desired hole position.

5. Place the drift pins into mounting posts.

6. Place the attached snap-ring clevis pins into the 2 drift pins.

7. Swing the snap rings down over the ends of the pin to secure the grader blade.

8. Lower the roller to the ground.

The roller has 3 horizontal positions. To cultivate along the edge of the work area, align the edges of the roller with the edges of the cultivator. To cultivate and area with no messy edges between cultivation passes, offset the roller to either side so that about 15 cm (6 inches) of the roller overlaps the last cultivating pass.

1. Park the machine on a level surface, lower the attachment, and engage the parking brake (if equipped).

2. Shut off the engine and remove the key

3. Remove the drift pin (Figure 8).

   3. Roller-support bar

4. Slide the roller to the desired position (Figure 8).

5. Insert the drift pin through the roller-support bar.

6. Insert the attached snap-ring clevis pin through the drift pin to secure the roller.

1. Lower the cultivator to the ground and ensure that the chain case is perpendicular to the ground (Figure 9).

   

   Figure 9

2. Pull the auxiliary-hydraulics lever to the operator grip to start the cultivator.

3. Slowly lower the cultivator until the blades dig into the soil and the roller touches the ground.

4. Slowly move rearward.

5. When the pass is finished, stop the hydraulics and raise the cultivator.

Important: Do not drive the machine across pavement or other hard surfaces without first raising the cultivator. Crossing hard surfaces with the tines lowered damages the tines and the property.

When transporting the attachment, keep it as close to the ground as possible, no more than 15 cm (6 inches) above the ground. Tilt it rearward.

Figure 10

1. No more than 15 cm (6 inches) above the ground
2. Tilt the attachment rearward.

• Inspect the area where the cultivator is to be used and remove all objects such as large rocks, trash, and branches before cultivating to prevent equipment damage.

• Always begin cultivating with the slowest ground speed possible. Increase the speed if conditions permit.

• Always use full throttle (maximum engine speed).

• Cultivate in long, straight passes. Turning with the tines lowered causes equipment and property damage.

• If a rock or other obstruction goes into the tines, disengage the hydraulics and drive the traction unit forward until the obstruction is dislodged.

• If you are using a traction unit with a flow divider (some wheeled units have flow dividers; refer to your traction unit Operator’s Manual), you can use the flow divider to achieve the optimal rotor and ground speed for your soil conditions as follows:

  1. Set the flow divider to the 9 o’clock position and the speed selector to the turtle position.

  2. Pull the auxiliary hydraulics lever to the operator grip to start the cultivator.

  3. Move the flow divider lever while moving the traction unit rearward until the cultivation results are ideal.

Grease the 2 fittings on the ends of the roller and 1 fitting on the 4-bolt flange on the left side of the main housing.

Grease Type: General-purpose grease

Important: Grease immediately after every washing

1. Park the machine on a level surface, lower the attachment, and engage the parking brake (if equipped).

2. Shut off the engine and remove the key

3. Clean the grease fittings with a rag.

4. Connect a grease gun to each fitting.

5. Pump grease into the fittings until grease begins to ooze out of the bearings.

6. Wipe up any excess grease.

Check the gear lubrication oil level in the gear case every 25 operating hours and change it every 200 operating hours or once a year, whichever comes first.

Oil Type: 85 W 140

1. Park the machine on a level surface, engage the parking brake (if equipped), and ensure that the drive-chain cover is perpendicular to the ground.

2. Raise the attachment high enough to place a pan under the drive-chain case and support the attachment with jack stands.

   Warning

   Mechanical or hydraulic jacks or the lift arms may fail to support the cultivator and cause a serious injury; use jack stands to support the cultivator.

   Do not use the lift arms alone or hydraulic jacks.

3. Shut off the engine and remove the key

4. Open the oil-fill hole on top of the drive-chain case (Figure 11).
