Troubleshooting navigatedown
A guide to solving common problems with your DR® Power Grader.
Most problems are easy to fix. Consult the troubleshooting table below for common problems and their solutions.
When performing any maintenance, you must first shut off the tow vehicle, set the parking brake and disconnect power from the battery of the DR® Power Grader by separating the fuse holder. Read the safety considerations section of your Owner's Manual before performing any repairs or maintenance.
- The scarifying teeth are set too low, causing too large a section of surface to be removed. Raise the height of the scarifying teeth plate to improve traction.
- There is too much weight in the weight tray. Remove some of the weight.
- The tow vehicle is not adequate for your application.
- The angle of the tow bar is not set correctly. Adjust the tow bar up for better grading or adjust the tow bar down for better scarifying.
- There is not enough weight for the hardness of the surface material. Add weight (no more than 80lbs) to the Power Grader to improve performance.
- The wheels are not lifted all the way up. Raise the wheels completely when grading or scarifying.
- The lower hardware is too tight. Loosen the lower bolt and locknut to allow the mold board to rotate during adjustment. Tighten all hardware when angle adjustment is done.
- The battery charge is low; charge the battery.
- Check the fuse and replace it if necessary. See your Owner's Manual.
- Loose wire connection. Check the actuator/battery cable connection, the battery terminal connections, and the Remote Control wire connection.
Operating Parametersnavigatedown
There are four different types of tow vehicles recommended for the DR® Power Grader. Each vehicle type has specific strengths, weaknesses, and operating parameters when used with the DR® Power Grader.
Lawn Tractor/Garden Tractor- 14 HP and/or 400-pound tractor minimum for the 48" Models.
- 19 HP and/or 500-pound tractor minimum for the 60" Model.
- 5-degree slopes or less.
- Material loosened during grading increases traction difficulties.
- Very good speed control and turning radius.
- Frequent scarifying teeth adjustment may be necessary to maintain traction.
- Forward motion of the DR® Power Grader may need to be initiated before ground contact.
- 500cc 4WD ATV recommended for 60” Model.
- Traction issues are less evident.
- More difficult to maintain a consistent speed of less than 5 MPH.
- Turning radius is large (best used for large, straight drives).
- Traction issues are less evident.
- More difficult to maintain a consistent speed of less than 5 MPH.
- Turning radius is large (best used for large, straight drives).
- The tailgate should be lowered for best visibility.
- Traction is excellent.
- Visibility is very good.
- With the increased power, the chance of accidentally damaging the DR® Power Grader's frame is increased. The towing speed MUST be kept less than 5 MPH.
- Do not use these types of vehicles; the DR® Power Grader is difficult to see.
- NEVER operate the DR® Power Grader with a truck (2WD or 4WD). Use of a truck will void the DR® Power Grader Warranty.
Tips & Tricksnavigatedown
Note: This information pertains to the most recent DR® Power Graders. Please refer to your Safety & Owner's Manual for instructions specific to your machine.
Clean out the bottom of the battery holder completely before re-installing the battery. (Powered Remote models only)
Lower the grader frame completely to the ground surface when transporting on a trailer, parking on a hill, or servicing the grader.
Tips
- Use additional weight (up to 80 lbs) in the weight tray when grading hard pack to begin scarification.
- Remove weight when the surface material loosens or when experiencing traction difficulties.
- Remove the weight 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, angle the hitch upward to raise the scarifying teeth to allow the mold board to create a smooth surface.
- Raise the scarifying teeth plate/tooth bar out of the ground before turning around or leaving the work area.
- The mold board can be mounted with the straight edge down for basic grading or for creating smoother surfaces in finer materials. It can also be mounted with the grooved edge down for more aggressive grading or for creating grooved surfaces in finer materials.
- To create a smoother surface in soft materials, the axle assembly can be positioned on top of the grader to prevent tire tracks.(EZ-Dial Model Only)
- When using a lawn tractor as the tow vehicle, put the lawn mowing deck in the highest setting or 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.

| Check general condition, e.g. nuts, bolts, welds, etc. | check | ||
| Verify that all nuts and bolts are tight | check | ||
| Check condition of shear pin | check | ||
| Hose down the DR® Power Grader to keep scarifying teeth plate clean and clear of debris* Note: Do not hose down battery and electrical components on powered remote models | check | ||

*Do not use a power washer to hose down the grader; this may force water through the seals on the height adjusting actuator.
Note: Consider the service intervals shown to be maximum under normal operating conditions. Increase frequencies under extremely dirty or dusty conditions.
