2. Measure the distance between the traction unit frame and the pivot tube as shown in Figure 18.

   

   Figure 18

   The right side of the machine shown

   1. Measure this distance.

   If the clearance is not between 0.06 to 0.18 inch, adjust the adjustable rod as follows:

   1. Remove the bolt and nut that secures the rod to the pivot tube (Figure 19).

      

      Figure 19

      1. Ball joint
      2. Decrease the gap

   2. Rotate the ball joint shown in Figure 19 to change the length of the rod as follows:

      • To increase the gap, shorten the rod.

      • To decrease the gap, lengthen the rod.

   3. Install the rod with the bolt and the locknut, and test the clearance again.

   4. Repeat this procedure until the gap is correct.

3. Tighten the locknuts that secure the spring rod until 1/4 to 1/2 inch (6 mm to 13 mm) of the threads are showing to apply tension to the spring (Figure 20).

   

   Figure 20

   1. 1/4 to 1/2 inches of threads showing (6 mm to 13 mm)

   Note: Adjusting the spring rod will vary the lift effort of the system; the longer the bolt ends, the easier it will be to lift the toolbar. Adjust the springs so that the lift force is comfortable. The greater the tension on the assist spring, the less ground pressure there will be on the toolbar.

4. Install the right-hand wheel shroud.

5. Install the rear wheels and remove the jack stands from under the rear of the machine; refer to your machine’s Operator’s Manual.

1. Position the lift handle to the transport position (upper most notch).

2. Rotate the eccentric bolt either direction until the toolbar tines are parallel to the notch in the lift arm (Figure 17 and Figure 21).

   Important: The eccentric bolt will not rotate 360 degrees. When it stops, do not attempt to force it further or you will damage it. Instead, rotate it back the other direction.

   

   Figure 21

   1. Desired position, parallel to the lift arm notch
   2. Notch in the lift arm

3. Torque the center pivot bolt (item 4 in Figure 13) to 175 to 225 inch-lb (20 to 25 N⋅m).

4. Tighten the nut that secures the eccentric bolt until it is secure, but do not over-tighten it.

5. Test the operation of the attachment.

Parts needed for this procedure:

Once the toolbar has been installed and the fasteners are tightened, use the following procedure to verify that the toolbar teeth are level:

1. Park the machine on a level surface.

2. Check the pressure of all tires and ensure that they are equal. Refer to the Operator’s Manual for more information on checking the tire pressure.

3. Lower the toolbar until the teeth just begin to make contact with the ground.

4. If the teeth of the toolbar contact the ground evenly, the toolbar is level.

   Note: If the teeth on one side of the toolbar contacts the ground before the other side, level the toolbar. Continue leveling by following the remainder of this procedure.

5. Measure the gap from the toolbar teeth to the ground on the side that requires leveling, then use the following table to determine which shim to install based on the gap measurement:

   Shim pack (Thickness in inches)	Change in Tooth height (inches) on Outside Edge
   110-7379 (.0747 inches)	1/8 inch
   110-7381 (1345 inches)	1/4 inch
   110-7379 and 110-7381 (.2094 inches)	3/8 inch
   110-7380 (.25 inches)	7/16 inch
   110-7379 and 110-7380 (.3247 inches)	9/16 inch

6. Loosen the bolts that secure the pivot tube bracket to create an opening between the frame and the pivot tube bracket (Figure 22).

   Note: Installing the shim may require that you remove the lift pedal to access pivot tube bracket. Refer to Installing the Toolbar Lift Pedal.

7. Install the shim(s) and tighten all fasteners.

8. Verify that the toolbar is now level. If not, adjust it as needed.

1. Read the documentation.

2. Store the documentation in a safe place.

To adjust the amount of downward pressure exerted on the ground by the tool, adjust the spring tension of the adjustable rod. Using a 3/4-inch wrench, rotate the spring sleeve casting on the adjustable rod in the right-hand thread direction to increase the downward pressure or the opposite direction to decrease the downward pressure (Figure 23).

Note: This does not change the adjustable rod setting performed in the Adjusting the Pivot Spring Tension and the Adjustable Rod Assembly procedure.
