A: Of the vehicles we've tested, utility tractors and four wheel drive ATVs perform best. Lawn tractors also work very well (minimum 14 HP/400 lbs. for the 48" model and 19 HP/500 lbs. for the 60" model). The lighter the towing vehicle, the more you have to adjust your scraping/grading depth in order to maintain traction. We don't recommend towing the DR® Power Grader in any vehicle where you can't easily see the grader (and any obstacles it may encounter).

A: Box scrapers usually have 4 or 6 non-hardened scarifying teeth spaced 12" apart. As a result, they are best suited for loosening soil. They don't do a good job penetrating extremely hard driveway surfaces (and their non-hardened teeth quickly wear out on these surfaces anyway). That's because they rely solely on the weight of the box scraper to dig – and on hard surfaces that's just not enough.

A: It won't grade areas covered with tall, thick vegetation. The vegetation will clog the scarifying teeth, making them ineffective. Similarly, if the area you are grading has a lot of rocks, the machine will perform better if you remove rocks that surface as you're grading (you can just toss them into the built-in weight tray). Finally the Power Grader is not designed to move snow.

A: We offer 3 basic options:
1) Delivery to a Depot
2) Delivery to Home or Business
3) Enhanced Home Delivery

A: We graded over 100 miles of rock-hard limestone roads with no visible wear on the carbide-tipped teeth. This same material is used on well drilling bits and excavating equipment. It will last for an extremely long time. If you do manage to wear out or damage the teeth, they are easily replaced.

A: We tested the actuator to over 800 cycles without any noticeable loss of power, so you won't need to charge it very often. When you do charge the battery, just plug it into any 110-volt outlet overnight. The battery charger is included with the machine. When you are done using the DR® Power Grader, we recommmend disconnecting the battery.

A: If you ever have questions about your DR® Power Grader, you can use our Owner Support area. It offers a rich resource of information including troubleshooting, Owner's Manuals and replacement parts. Should you have additional questions, one of our Product Specialists can help you. These folks have in-depth knowledge of the DR® Power Grader. They’ve spent many hours in training and they have also put the machine through its paces mowing in a variety of conditions, so they know what they’re talking about. If necessary, we can get replacement parts to you right away or direct you to one of more than 1,500 authorized DR Friendly Service Centers nationwide.

A: Simply put, you can try it on your own property for up to 6-months.

A: 2 Years for Residential Use, 30 Days for Commercial Use.
