Discard the parts that were not necessary for your machine.

Parts needed for this procedure:

Note: Make sure that the front and rear tires are inflated to 28 to 41 kPa (4 to 6 psi).

1. Block up the rear of the machine and remove the rear tires.

   Note: Position the blocks under the rear wheel motor mounts.

2. Loosely secure a mounting bracket assembly to the right and left foot rest tubes with 2 bolts (1/2 x 3-1/2 inches) and locknuts (1/2 inch). Position the mounting bracket assemblies and bolts as shown in Figure 22.

   Note: The right mounting bracket does not need to be installed if the machine is equipped with a midmount tool bar.

Parts needed for this procedure:

1. Position the lift arms so that the mounting hole of each lift arm bracket aligns with the holes in the mounting brackets (Figure 23).

2. Secure the right lift arm to the mounting bracket with a clevis pin and hairpin cotter pin (Figure 23).

3. Loosely install one end of the torsion tube to the right lift arm with 2 bolts (3/8 x 1 inch) and locknuts (3/8 inch); refer to Figure 23.

   Note: Do not tighten the fasteners at this time.

4. Secure the left lift arm to the mounting bracket with a clevis pin and hairpin cotter pin (Figure 23).

5. Loosely install the other end of the torsion tube to the left lift arm with 2 bolts (3/8 x 1 inch) and locknuts (3/8 inch); refer to Figure 23.

   Note: Do not tighten the fasteners at this time.

Parts needed for this procedure:

Note: Optionally, you can purchase a 60-inch blade. Install it as directed for the 40-inch blade in this section.

1. Loosely secure a brace plate to each of the inner mounting tabs on the blade assembly.

   Note: Position the brace plates as shown in Figure 24.

2. Loosely secure the front of the lift arms to the blade mounting brackets and brace plates with 4 bolts (3/8 x 3 inch) and 4 locknuts (3/8 inch); refer to Figure 24.

   Note: Using the upper mounting holes on the blade mounting brackets will make the blade operate more aggressively (Figure 24).

3. With the blade resting on the level surface, tighten the fasteners securing the lift arms to the blade (Figure 24).

   Note: Torque the fasteners to 19 to 24 N∙m (14 to 18 ft-lb).

4. Tighten the bolts and locknuts securing the ends of the torsion tubes to the lift arms (Figure 23).

   Note: Torque the fasteners to 19 to 24 N∙m (14 to 18 ft-lb).

Parts needed for this procedure:

1. Mount the lift-arm foot pedal to the outside of the left lift arm with 2 bolts (3/8 x 3 inch) and 2 locknuts (3/8 inch).

   Note: Position the foot pedal as shown in Figure 25.

   

   Figure 25

   1. Lift-arm foot pedal

2. Remove the lower nut and bolt securing each hitch tube mounting bracket to the vertical frame tubes (Figure 26).

   Note: Discard the nut and bolt.

3. Using the open hitch tube mounting holes, secure a spring bracket to each hitch tube bracket/vertical frame tube with a bolt (3/8 x 2-3/4 inch) and a locknut (3/8 inch).

   Note: Position the spring brackets as shown in Figure 26.

   3. Extension spring
   4. Lift arm

4. Pull back on the handle to raise and lock the blade into the transport position.

5. Tighten all remaining fasteners.

6. Connect the extension spring to the lift arm and to a spring rod.

7. Insert the spring rod into the hole in the spring bracket and loosely secure it with a locknut (3/8 inch).

8. Repeat steps 6 and 7 on the opposite side of the machine.

9. Install the rear tires and remove the blocks from under the rear of the machine.

   Note: Torque the lug nuts to 61 to 75 N∙m (45 to 55 ft-lb).

The spring adjustment controls the force that it takes to raise the blade to the transport position. If the spring is too loose, it will be hard to raise the blade to the transport position. However, too much spring tension causes the blade to float excessively during operation.

1. Lower the blade to the floor.

   Note: When the springs are properly adjusted, the entire length of the bottom of the blade will be no more than 6 mm (1/4 inch) off the floor.

2. Rotate the spring adjusting nuts (Figure 27) clockwise to raise the blade or counterclockwise to lower the blade.

   

   Figure 27

   1. Adjusting nut

Pull back on the handle to raise and lock the blade into the transport position. Press the locking pedal to release the blade into the operating position.

You can use the blade to push or pull sand and dirt. With the blade in the operating position, simply push forward or pull back slightly on the handle or press on the lift arm foot pedal to control the plowing action.

Note: If the wheels spin while plowing, raise the blade slightly by pulling back on the handle. At times the engine may begin to overload. When it does, gradually release the traction pedal to increase the engine speed and power

1. Carefully remove the adjusting nuts securing the spring rods to the spring brackets.

   Warning

   If the springs are under tension, they could cause personal injury.

   Carefully release pressure from components with stored energy.

2. Remove the spring rods and springs.

3. Lower the blade to the floor.

4. Remove the hairpin cotter pins and the clevis pins that connect the lift arms to the mounting brackets.

5. Raise the front of the machine and slide the complete blade assembly forward and away from the machine.
