Get Real Work Done with Your Lawnmower

The ABI Gravel Grader is an effective and patented gravel driveway grader designed specifically for the riding mower. With a spring-loaded grading box and ripper teeth, it does the real work needed to renovate and prepare your gravel driveway properly. Unlike many competitors, the ABI Gravel Grader is crafted by Americans in the USA from heavy-duty steel. Unique in the market, the ABI Gravel Grader is both performance-oriented and cost-effective! Compatible with lawn tractors, zero-turn mowers, utility golf carts, and small ATVs with a rear towing hitch between 14 - 27 horsepower or 300 - 550cc.

Transferred Weight

As the wireless electric actuator adjusts the downward force on the springs and grading box, the hitch of the Gravel Grader uses the weight of the mower as leverage to apply force to the loosening and grading action. Unlike other tools, blocks, rocks, or weights aren’t needed for this tool to work!

Gets Real Work Done

Unlike many of our competitors, whose loosening teeth only penetrate 1/8″ of an inch at a time, the ABI Gravel Grader’s ripping teeth will loosen up to 1¾” deep. This ensures the driveway has enough loosened gravel to properly grade, producing a smooth driving surface.

Crown Control

A proper crown helps minimize recurring potholes and the washboard effect. The ABI Gravel Grader’s exclusive-to-its-class Crown Control mechanism can pull loose gravel from the edges of a driveway and properly re-establish a crown.

ABI Attachments is known worldwide for “Innovation… not imitation”! The attachments we design are made in the United States, unique, and are full of features that separate us from our competitors. The Gravel Grader is no different! With features such as Coiled Springs, Crown Control capabilities, and an adjustable grading box, the ABI Gravel Grader is the only gravel attachment that will do real work from behind a riding lawnmower!

Coiled SPrings

Coiled Springs

The patented Coiled Springs of the ABI Gravel Grader allow the forgiveness needed to pull through tough areas. When using the wireless remote, the actuator will transfer a measured amount of downward force, from your mower, to the grader box. These Coiled Springs give you an exact amount of grading action without “spinning out”. When other grading attachments leave you stuck in the middle of a job…the Coiled Springs of the ABI Gravel Grader guarantee you, and your gravel driveway, success.

Grader Box

The ABI Gravel Grader comes with a 48″ grader box with ripping teeth that will loosen up to 1¾” deep! Unlike many of our competitors, whose loosening teeth only penetrate 1/8″ at a time, the ABI Gravel Graders ripping teeth do real work, ensuring the driveway has enough loosened gravel to properly grade, producing a smooth driving surface. These ripping teeth are adjustable and easily replaced, making them the most effective ripping teeth, for a mower designed gravel grader, on the market. The Grading Box has a pitch control, which is critical to its effectiveness. By lengthening or shortening the adjustable link, you can create more ripping or grading action depending on the results needed at the time.

Grader Box
Ripping Teeth

Ripping Teeth

The ABI Gravel Grader’s ripping teeth loosen up to 1¾” deep! These ripping teeth are adjustable and easily replaced, making them the most effective ripping teeth, for a mower designed gravel grader, on the market.

Gravel Capture Wing

Material Recovery Wing

The Material Recovery Wing allows material outside of the box width to be pulled to the center of the tool. The wing can be adjusted and set to below grade in order to grab loose debris on slopes.

ABI Gravel Grader

Reversible Grading Blade

The 1/2″ thick grading blade can be flipped to expose rock teeth to feather and sift material or a solid blade to move material without sifting.

Wireless Actuator

Wireless Actuator

The ABI Gravel Grader comes standard with an electric actuator when most of our competitors make their actuators optional. Some competitors even tie an inexpensive actuator to a cable system that inevitably will rust, seize and break. The ABI actuator is commercial grade, has an 8″ stroke, and is weather sealed for longevity. Using the wireless electric actuator’s downward force on the springs and grading box, the hitch of the Gravel Grader tops out against the mower using the weight of the operator and mower to put applied force to the loosening and grading action. The actuator can be connected to your mowers battery or to an onboard battery. (The onboard battery is not included)

Crown Control

Crown Control

The ABI Gravel Grader’s grading box has an easy to use “crown control’ mechanism that makes it the ONLY gravel grader, for a riding mower, that can pull your loose gravel from the edges of your driveway and properly re-establish a crown. And to assist with the “recapturing” of gravel that’s lost to the sides of the driveway, the ABI Gravel Grader comes standard with a “gravel capture” wing that is easily attached and removed.

Stabilizing Wheels on ABI gravel grader

Stabilizing Wheels

The ABI Gravel Grader is balanced and stabilized by two substantial gauge tires which not only create a “ground plane” for the grader box, but also work in conjunction with the “coiled spring action” giving the ABI Gravel Grader its unique and patent pending “controlled force”. Because the wheels create a “ground plane” with the mowers wheels, leveling a gravel driveway is far more attainable.

The ABI Gravel Grader is packed full of advantages that changes the game for lawnmowers and pull behind graders! Advantages like: 1) Being able to reestablish a crown. 2) Using the weight of the mower instead of concrete blocks for weight. 3) And being able to adjust the grading box for deeper ripping or pulling more material. These are advantages our competitors cannot provide.

Gravel Grader Controlled Force

Controlled Force Technology

It is critical to understand why the ABI Gravel Grader works, when other driveway groomers fail! It is the physics behind our coiled springs and the applied “controlled force technology” that comes from the weight of the operator and mower! This innovative and patented technology eliminates the old fashioned practice of adding concrete blocks to the grader so it can dig into hard packed gravel and actually work. Using the wireless electric actuator’s downward force on the springs and grading box, the hitch of the Gravel Grader tops out against the mower using the weight of the operator and mower to put applied force to the loosening and grading action. One of the failures of simply applying weight to a competitor’s frame is that when the loosening and grading components hit compacted gravel, or carry too much material, the mower or tractor will spin out, making the grader useless. This is not true with the Coiled Springs of the ABI Gravel Grader! These “Coiled Springs” will allow the forgiveness needed to pull through tough areas. When using the wireless remote, the actuator will allow a measured amount of downward force to the grader box. This combination gives you an exact amount of grading action without “spinning out”.

Crown Control

Crown Control

Being able to properly shed rainwater helps minimize reoccurring potholes and the “washboarding” that plagues so many gravel driveways! The ABI Gravel Grader’s grading box has an easy to use “crown control” mechanism that makes it the ONLY gravel grader, for a riding mower, that can pull your loose gravel from the edges of your driveway and properly re-establish a crown. To assist with the “recapturing” of gravel that is lost to the sides of the driveway, the ABI Gravel Grader comes standard with a “gravel capture” wing that is easily attached and removed.

Ground Plane Effect

Ground Plane Effect

With over 50 years of contractor grading experience to draw from, ABI Attachments knows that the design of a grader, no matter how big or small, should be with the grading box placed between two sets of wheels, creating a “ground plane” for the most effective grading possible. We could not leave that design out of the ABI Gravel Grader! The ABI Gravel Grader is balanced and stabilized by two substantial gauge tires which not only create a “ground plane” for the grader box, but also work in conjunction with the “coiled spring action” giving the ABI Gravel Grader its unique and patent pending “controlled force”.

    Very good and easy to use. The folks at ABI are a class act. Customer service is great. My only complaint were the tines broke fairly easily. They sent me plenty of new ones to replace. Highly recommend.

    Best customer service I’ve ever had. Had a few hiccups with the actuator but you guys caught that and sent me one that seems to fit the bill.

  3. Kevin McMichael

    Good design overall with one major flaw, actuator top has a pressed cap which breaks easily, solid tube would be more reliable otherwise machine works as advertised and company is very responsive to replacing broken parts

    Great product. Great product for the price. Installed a Peak back up camera to operate full time so I do not have to look back all the time. Now doing seven driveways in my area.

  5. Donald Offenbacher

    Fantastic tool. I have not done any thing with our drive in more than 5 years. I began working with the gravel grader and after about 4 hours I had all of my holes filled and the drive was level and crowned. I still have work to do as the center of my lane was full of weeds and I will be using the gravel grader to continue clearing weeds from the center of the lane. I am absolutely sold on the gravel grader and have nothing but compliments about it and the job it allows me accomplish. I also found the staff at ABU to be great people to work with from the first phone call to my purchase.

    Got my gravel grader and was very pleased with it, it was ready to go minus the battery. It is very well built, very heavy duty, I tried it out and it works great on my driveway. I am very pleased with it. Brian was my salesman, he is very good to work with. Thank You Brian.

    Great Attatchment for repairing and maintaining my 1500 foot stone driveway. Used it one time for a couple of hours one day and my drive looked like I just had fresh stone put in. The gravel grader was virtually fully assembled and very easy to use. Thank you ABI for a fantastic tool. I have and will continue to recommend this product and your company.

  9. Anthony Dancausse

    Great tool. I truly had my reservations on this product. Once I got it and started using it those all went away. There is a bit of a learning curve but it’s easily over come just play around with the settings on the grader. My drive was pot hole city not anymore and honestly no rock was added to accomplish this. Awesome product.

  10. Ron Bumgardner

    It Did The Job. I bought this grader with the intention of maintaining the dirt Lane and driveway that I own. Usually after 2 years I have to hire somebody in to grade it for me lust caution quite a few dollars to do this. Now I’m able to do this with my lawn tractor two, to three times a year and have a smooth driveway all year round. It does a great job, it has never failed me yet

    Sales Rep Tyler was excellent, no pressure sales. Had a few concerns from previous reviews which he addressed and took care of. Shipment was fast and easy to unload. I was able to unload within minutes and put the grader into action within an hour. The product is as advertised, and I am happy to say that my 500ft + driveway has never looked better. Cant wait to see how it tackles my roadway to the lake. Thanks ABI you have made my work here a lot less difficult.

  12. Don Ruggles

    I searched all over for some way to grade and or maintain my 600 foot gravel dtiveway with 100 x 75 parking area. The hardpack has not seen any maintenance in 15 years. I live in New Hampshire and had pot holes and ruts that were 6″ to 12″ after this past winter. After a lot of on line research, i bought the ABI gravel grader. I did not think really think I could grade or maintain my driveway isong my 22 HP Husqvarna lawn tractor, but am amazed how effectively this grader works. I was very concerned tgat I would just spin the tires trying to grade with a lawn tractor, but could not be more impressed with the grader!! I have never had any grading experience. I the grader simply does what ABI advertises and more!! I spent about 3 hours us ing the grader and the driveway and parking area is in freat shape!! Thanks ABI!! The grader is high quality and easy to use. I highly recommend this grader!!

  13. Paul Hacking

    Perfect for what I needed and the Customer Service has been exceptional! I have loved everything about my gravel grader. I am putting in landscaping around my new house. This tool has come in very handy as I have leveled out dirt and spread gravel around a good part of my acre lot to keep weeds down. It feels like I am manicuring my gravel and my dirt every time I use it. The process of purchasing it could not have been better the grader is well-made and I fully expect it to last for many years to come.

  14. Les McAfee

    Used it a several times getting a 100 yard driveway on an incline back in shape. Unit works great. Especially like the ability to crown the driveway. I have a lot of rocks here and the springs just let it ride over them. Never broka tine yet? Very well built. Only thing I would like to see is a drfferent design on the hitch. Since it is on an incline my mower struggles with traction on the uphill. I have suitcase weights for the back but if used you cannot turn very much as they impact the hitch mechanism. But hey, I’ll deal with that as a minor issue. Excellent product. Highly recommend over the competition.

  15. John Scammacca

    Excellent attachment for repairing and maintaining a gravel driveway. Used it right off the truck for a couple of hours and my drive looked like I just had fresh stone put in. The gravel grader was virtually fully assembled and very easy to use. It is extremely well built and best of all it’s made in the USA. I highly recommend this product to anyone with a gravel driveway to keep it maintained and looking good. I will Recommend your company to everyone.

  16. Yuri Whitehead

    I had been filling pot holes by hand ever since I bought my house – this is a labor and time intensive process as my driveway is 500+ feet long. This spring I decided to look for a better way to maintain my driveway. I stumbled upon the gravel grader and am extremely pleased with the results. Glad I didn’t go with a cheaper option as the grader is well designed and built like a tank. It exceeded my expectations and my driveway looks and feels great!

    I got the new Gravel Grater to pull behind my 52″ 27HP zero turn lawn mower. I was actually thinking of investing many thousand of dollars on a tractor with mower deck just to maintain the four different driveways and service roads on my property. Let me tell you, this little guy works very well. No B.S. involved. I started out with several passes- very light pressure on the hard packed driveway. Soon I was digging deeper with each pass. It took a little patience but provided instant gratification with each pass. It have been four years since anyone touched this gravel road and it had all kinds of rocks and weeds growing to the point that we had a hard time finding where the driveway stopped and the lawn began! No more. The front of my house looks like a professional crew just finished putting down a new driveway. Honestly, the little rig arrive almost completely assembled and required a $30 battery to operate. Fine quality and outstanding engineering combined with excellent use of weight and balance to make this tool perform beyond my exp

  19. Marshall Smith

    What an AWESOME tool. The ABI Gravel Grader came on a pallet fully assembled except for connecting the wiring harnesses to my Lawn Tractor and the hitch. I was able to rip up our 150 Ft loop driveway, smooth the surface and crown it in about 3 hrs. That includes me learning how to do it since I had never grade a drive before and someone that has could probably do it quicker. It was easy to figure out and being able to raise and lower the rippers as I felt my lawn tractor start to slip helped me avoid spinout. I am totally impressed and highly recommend the ABI Gravel Grader to anyone with a gravel drive and an RTV/UTV/lawn tractor. KUDOS ABI

      Hi Marshall! Glad to see you enjoying how the Gravel Grader gets real work done! Thanks for taking your time to leave a review!

    Abi has been the best customer service and shipping was far and easy. My grader has out performed my expectations. I’ve been working around road equipment most of my life and this small machine works as well as a large commercial unit for a lot less money highly recommended

  21. Stan Zehr

    Love my gravel grader; works as advertised. I have used it many times, and also have used it for grading/leveling dirt when seeding new lawn areas, etc. My only regret is I ordered with simply clamps to connect to the tractor battery. After a couple of uses, I wired in a DC plug, so I could plug into the power outlet on my tractor. Wish I would have ordered the grader a few years earlier than I did.

  22. RichardBledsoe

    First of all, I gave this unit 3 stars only because it’s to light weight for my road application. Some of the portions of my road are so compacted, they are like sidewalks. I set the sacrificing teeth to less than half an inch, and within my 3rd of a mile road, I broke 3 teeth. I ended up breaking 10 for the afternoon of grading. The teeth break where the threaded portion begins. I purchased extras which was a good thing. Once the road is in better shape, it wont be as hard on the grader. Conclusion, I should’ve purchased the rascal.

  23. Terry

    My sales rep Korey was very helpful. I had concerns my ATV (Honda rancher 350) could pull the Gravel Grader up my 1/2 mile very steep drive in the NC mountains. While it did struggle a little when dragging material it was manageable. The Grader is a great fit for my road. I was paying $1000 to have someone else do the work so the Grader will be paid for very soon.

  24. Larry Spreckelmeier

    My experience was very good. I felt very well taken care of and spoke with people that know what they’re doing and they care about the product and the customer. The fit and finish of the product is very nice. It appears to be powder coated, which is a good finish for products like this. I was also delighted to see that most of the product is assembled.

    Overall not a bad little piece of equipment. Takes time to cut into the hard pack but once it starts it does good.
