POWER GRADER
Operating Tips

Use additional weight (up to 80 pounds) by placing two Cinder Blocks between the Crossmembers when grading hard pack to
begin scarification.

Remove any added weight such as Cinder Blocks when the surface material loosens or when experiencing traction difficulties.

To create a smoother surface in soft materials, the Axle assembly can be positioned on top of the Grader to prevent tire tracks.

Remove the weights when grading in muddy conditions or sandy soil.

Expect to make several passes with the DR POWER GRADER to repair a roadway, depending on the condition.

Avoid filling Pot Holes filled with water, wait until the holes are dry.

Use the DR POWER GRADER to work the edges of Pot Holes that are more than 4 feet wide to loosen the sides before you
begin filling them.

Avoid large rocks, embedded ledge, cattle guards, or similar obstructions.

Remove rocks pulled to the surface during grading to provide a better final graded surface.

They can catch under the lawn deck (for lawn tractors).

Once you have adequately scarified the road surface, raise the Scarifying Teeth Plate to allow the Rear Scraper Blade to create a
smooth surface.

Raise the Tooth Bar Plate out of the ground before turning around or leaving the work area.

When using a lawn tractor as the tow vehicle, put the lawn mowing deck in the highest setting or just remove the deck to obtain
the highest ground clearance.

For ease, do your spring grading before re-installing your lawn deck for the summer mowing activity.

When using the DR POWER GRADER to prepare a seed bed, remove all large debris before grading.

Use the Optional Drag Screen to create the best finish in sand or to incorporate seed.

Use Low Gear when using an ATV as the tow vehicle – Do not exceed 5 MPH while grading.

The maximum speed when not grading is 10 MPH.
FAQs
Question: Can the DR POWER GRADER create a crown in the road?
Answer: No, but you can maintain a crown in the road by grading each side separately.
Question: Can the DR POWER GRADER ruin the crown in the road?
Answer: Yes, but only if you grade down the centerline of the road.
Question: Can I use my Lawn Tractor in sandy soils?
Answer: Lawn Tractors do not perform as well as an ATV or Utility Tractor in sandy soils.
Question: Why does the Hitch have a Shear Pin?
Answer: The Shear Pin will absorb the shock by breaking if you hit a large rock, ledge, or other obstruction offering some
protection to your DR POWER GRADER and Tow Vehicle.
Lower the grader frame completely to the ground surface when transporting on a trailer, parking on a hill, or servicing the grader.
Frequently check the tightness of the bolts that fasten the Tooth Bar to the frame.
