Parts needed for this procedure:

1. Insert the spring washer onto each end of the roller shaft (Figure 3).

2. Insert a roller arm onto each end of the roller shaft (Figure 3).

3. Secure the roller arm to the 2 roller shafts with the hardened washer (right side only) and 2 roller shaft screws. Thread the 2 grease fittings onto the 2 roller shaft screws if not previously assembled (Figure 3).

4. Insert the roller-scraper mounting tabs into the slots in each of the scraper arms (Figure 3).

5. Install the scraper arms to the roller arms (Figure 3).

6. On the left side of the roller arm, secure the scraper arm to the roller arm with 2 carriage screws (3/8 inch) and 2 nylock nuts (3/8 inch) (Figure 3). Repeat on the right roller arm.

Parts needed for this procedure:

1. Align the 2 roller-arm mounting holes with the 2 side plate mounting holes.

2. Secure the roller assembly to the side plate with the 2 flange bushings, 2 flat washers, 2 hex-head bolts (5/8 inch), and 2 nylock nuts (5/8 inch).

   Note: The roller contacts the turf a few inches behind the tines and turf hold downs.

Parts needed for this procedure:

1. From the left side of the machine, secure the spring assembly to the side plate and the roller arm with the 2 spring brackets, 2 carriage bolts (3/8 inch), and 2 nylock nuts (3/8 inch). Repeat on the right side of the machine.

2. Grease each roller fitting with a number 2 lithium-based grease, approximately 15 ml (1/2 fl oz) per end.

3. Loosen the 2 lower nylock nuts (3/8 inch) securing the scraper arms to the roller arms. Adjust the roller scraper until there is approximately 0.15 cm (0.060 inch) clearance between the roller and the scraper. Tighten the nylock nut.

4. Tighten all the fasteners.

   Note: The spring is pre-adjusted at the factory, but to ensure proper down-pressure on the roller, verify that the compressed spring length is 38.1 cm (15 inches). Adjust as required.Shortening the spring adjustment does not increase the operating down pressure. It will raise the transport height and delay the contact with the ground when engaging the coring head.
