    The Ground Hawg backhoe easily walks itself around the work site with the bucket and boom. Since it's not wheel driven it's nearly impossible to get it stuck and it will get into those tight spots without tearing up the grass or making big ruts. With a tongue weight of only 100 lbs, the Ground Hawg can be rolled around wheel barrow style on firm, fairly level surfaces using the built in handles. The Ground Hawg doesn't need to be hooked up to a tow vehicle other than for over the road travel.

  10 Reasons to build a Ground Hawg Backhoe
  1. You save money.  Building a Ground Hawg yourself can save you thousands over the cost of buying a commercially built machine.  You'll not only save on the build up of the machine, you'll save on repair and maintenance cost over the life of the machine.
  2. Compared to other higher priced machines, the Ground Hawg gives you big machine performance at the small machine price.  The Ground Hawg has a 11'8" reach compared to the Trenchermans 8' reach, nearly 50% more reach!  The Ground Hawg dumps at over 6'6", high enough to load most trucks while the Trencherman dumps at a height of only 3'6". The Groundhawg not only has the extra reach, it has the extra power to tackle those tough jobs!
  3. Ground Hawg uses a 25% larger pump and has a 140 degree swing, giving you the flexibility to tackle more jobs with greater efficiency.        
  4. By building the machine yourself, you'll never have to pay someone to work on your machine.  You'll be the expert.
  5. Building your own backhoe will give you a feeling of pride and accomplishment.
  6. Save big money by doing all your excavating and landscaping projects yourself.  
  7. You can make money doing work for others.  Your Ground Hawg backhoe will pay for itself
    fast and it's always worth more than it cost to build, should you decide to sell.
  8. The Ground Hawg is designed to give years of rugged service, with replaceable pins and
    bushings and 14 grease fittings.
  9. Maintaining the Ground Hawg is quick and easy, a few shots of grease and an occasional oil change is all that's required.
  10. Don't have a lot of fabricating experience? You can still build a Ground Hawg. Our plans guide you through from start to finish with over 50 pages of  detailed instructions and drawings. A full scale pattern is included for the bucket. The plans include a complete list of all the parts, part numbers and discount suppliers you'll need to get your machine built quickly. Here's what you need to get: 8HP engine, hydraulic cylinders, hoses, fittings, control valve, pump and bracket, filter, tank, seat, wheels, trailer coupler and steel from your local supplier.
  11. Cost to build varies with location and suppliers, but it always pays to shop around for the best deals. Most builders report spending $3000 to $3500 buying everything new, less if you dig up used materials, steel, engine, seat, wheels, etc.

Subject: Another Ground Hawg up and running in Sydney
Sir,
Thank you very much for the Ground Hawg plans I received in the mail a few months ago. It took me three months of evenings and weekends to build the Ground Hawg. I am very happy with the outcome. I like doing things myself, I've never been involved with hydraulics before, but your simple plans gave me the confidence to give this project a go. I am so pleased, I've learned so much and I've got a useful machine. I've bought a farm and will be excavating for roads, foundations, sewer, pipes, etc.... It will come in very useful and as a owner builder will save me thousands on hire fees over the years. The cost of hydraulics in Australia is frightening....but your suggested supplier was happy to ship all the parts over to me from the States, I not only saved money, but got exactly the right parts and fittings. The parts list in your drawings with catalogue numbers was very valuable to me. The only hydraulic components I didn't get from the States were the rams. My friends and neighbours seemed a bit worried for me....building a backhoe in my garage....but the closer I got to finishing the more confident they seemed that it would work. I've got a neighbour who runs an excavation company for a living....he was very worried for me, but he is now very impressed with the Ground Hawg and has confidence that it will easily do all my farm work. He has been amazed at how quickly the project has been finished.
Thanks again, Kevin from Sydney (Soon to be excavating in Upper Colo)

Got the plans today, wow really fast. I can't wait to get started. Thanks again, Scott R.

My six year old son and I had a great time building this backhoe. I used your prints from the main pivot to the bucket, then I "improvised" on the engine end of the backhoe. I used a complete riding mower, retaining the hood and gauge cluster. The blueprints and drawings were spot on and everything went together very nicely!! Great project!!
Hopefully it'll dig a hole or two once the snow melts...

Hi Scott, I ordered my plans about 6 years ago and have been working on my machine off and on ever since. Life kinda got in the way a few times but I've had a lot of fun while also trying to find either the money or time to finish it. I finally got things together last week and everything worked as it's supposed to...with some minor adjustments. Now all I have to do is find somewhere to dig some holes and move some dirt! Thanks for a great set of plans which allowed me to enjoy building my hoe while learning a bunch of new skills.

Building the backhoe was my winter project. The written instructions were great. Scott was always ready to help with the few questions that I had. I was able to get drops from a local steel supplier which saved in cut charges and was able to find a used Honda engine. I believe that the cost estimate was right on. Several people have looked at it and are amazed first that I built it and second how rugged the machine is. I am currently using it to cut down a bank in preparation for a new barn. It sure handles the clay soil real well. It was fun to build and fun to operate. I'm sure my son will be calling me soon to use it on some project that he has.

It took me 3 months working in my spare time with my brother-in-law helping me with the welding in his shop on the farm. Finished it in October 2010 and I just finished the Thumb Attachment April 11 2012. I absolutely had a ball building this backhoe! I modified the seat pedestal a bit, made of 3-1/2" square tube with 3" square tube with 3 holes drilled 1" apart for vertical adjustment and a slider for back and forth. I went a little overboard on the engine too. I got an 11hp electric start pretty cheap. The battery box is mounted on the right side on the rear crossmember. I also put 14" trailer tires with 5 lug hubs for highway towing. Well pleased with the work it does, dug a 8ft. square hole 7ft. deep the first time used and it worked fantastic.

Here are some Pics of my finished backhoe. The Build price was probably just under the advertised cost (used engine, seat, etc.).
The only thing more fun than building it is operating it.
I keep thinking of more things I can do with it. I just might have to build that little dozer of yours. Thanks again for your affordable drawings.

Overall sweet little machine. I am very happy in how it turned out. Everyone in the neighborhood
thought I wasn't thinking straight when I began this project and most are amazed and impressed with how this project ended up. Once you jump into it and understand the plans it was a breeze.
Would really like to make it move a litte faster though. Any suggestions would be appreciated.

Suggestions: You can run the engine at full throttle to increase pump flow and cylinder speed. A larger pump will also increase speed, but it will require more power as well.

Just wanted to let you know I finally finished this project! I am very pleased with the outcome and am impressed by the machines abilities! It was quite costly however-I have yet to figure out my expenses but it wouldn't suprise me if I spent somewhere in the $4,000 dollar range. Nonetheless I really enjoyed building this machine and am looking forward to using it which I am about to do today!

Hi Scott,
I built one of your backhoes a few years back up here near Winnipeg, Manitoba, Canada. It has been working fine over the years. Most of it I built with used and tired parts that I am slowly replacing as I can afford it. Would you have a line on a reasonably priced set of control valves?

Hello,
Well I have purchased and built all the products on your website. Now I have run out of stuff to build and was inquiring if you have any other future projects to release and if not may I make a couple of suggestions. I could really use a log splitter and lawn vacuum. After building your backhoe I was just thoroughly impressed and wanted more. I have built the go karts for my boys and have a lot of fun on them myself. You seem to have a great talent in designing and creating plans for us laymen home builders that I thought you might take request for things that we could use around the ranch.
Thank you,

Our response: Thanks for the kind words Dewayne. We have been working on some great new plans projects and expect the first to be released later this year (2009).

It surprised me how well it dug. My land is loaded with rocky soil and about every third scoop full has at least a football size rock securely embedded. After about 5 or 10 minutes of practice I got the hang of it and was digging like crazy. In no time at all I was about 4 feet deep. I was curious, so just for the heck of it, I tried picking up my 450 lb. red box blade scraper that I tow behind my truck with the freshly built thumb attachment,....the Ground Hawg did it effortlessly.

     September 15, 2007: Scott, I thought you'd be interested in the final results of my project. I bought your plans in April, started acquiring tools and a donor tractor in May and June, purchased the steel on June 27th, the hydraulics in late July, and this last weekend I was digging dirt and clearing ditches! As you can see from the pictures, there were a few modifications. The engine is an electric-start, vertical-shaft Briggs twin 16HP from the donor tractor, so the engine mount is special. I also used the seat and fuel tank combination from the donor tractor, too. I also chose bolt-on teeth shanks with replaceable teeth for the bucket. But other than that, it's pretty much as the plans call for it. I enjoyed building this very much. I keep telling my wife, "When I build the next one...." :) Thanks again for your well-engineered plans.

     February 27, 2007: Greetings from Finland
And thank you for the plans I received a bit over a month ago. I duly set out to build the "Groundhawg" immediately after receiving those plans, mostly out of materials found at a scrap yard and now the backhoe is in the early trial states. I didn't experince any great difficulties in making the "Groundhawg", I had to do some adjustments required by the metric world and the difference in the available cylinders. Everything seems to work O.K. Anyway, thank you for the plans: I was able to make a much needed backhoe for my wife and at the same time "globalize" a few jobs to Finland from China for a month or so ( we originally contemplated buying one from China). I attached a couple of pictures of the "Maasika" ("Groundhawg" in Finish) in the making and in the ready. I haven't made the bucket yet, that remains the last thing to do, after I get my engine running correctly. I decided to make a plate to which I can attach other tools. Thanks for a good product.

     Since we last spoke I have completed my Groundhawg, and set out to learn how to use it. It didn't take long and the first job I did with it was to dig out a stump about 3' in diameter! Now that might not be the smartest way to break the machine in but I figured if it can handle this it will do anything I want it to. I was really suprised at how much power this machine has. Now I'm working on the real reason I built this machine and that is to make a road down a steep hill on my property. This machine is working great and I'm about halfway down the steep wooded hill. The Groundhawg is very stable with the adjustable stablilizers. I would like to say Scott, that this was a big leap of faith to build something like this. I really didn't know if it was going to dig or just scratch the ground. It is very impressive and I had a great time building it this last summer. Now I have a capable machine that will be with me 'till the end, then someone can use it to put me in the ground with lol.

May 13, 2002: Scott, The ice has melted from the lake. I had the backhoe flown in by helicopter and it's now working on site. I am very impressed with the backhoe's performance. I am operating on some pretty rugged terrain and it moves around well, digs rocks and earth that couldn't be moved otherwise. I dislodged stumps with some persistence. The thumb works well. The machine tolerates some ham-handed operating as I learn it. The design is good, and the machine does exactly what it's meant to do.
Thanks for your good work and support.
D Palmer, Alaska
June 3, 2002: Report number 5 from Alaska:
Scott, I want to tell you again how pleased I am with the machine. Buying your kit was a leap of faith, considering the freight costs to Alaska and the unknown design, coupled with the fact that until helicoptered onto the site I wouldn't know if it worked well for the purpose. Bringing it out again for repairs or modifications would present major logistical and financial problems. I have worked the machine for several hours and the result has been outstanding. If there is such a thing as good geometry for linkage and bucket design, this has it. I have dug boulders from the hillside that could only be rolled with the bucket or chainsaw winch, barely. I've chipped at coarse rock, excavated stumps, and negotiated some tough terrain. The result is a building site where none existed. I have moved enough dirt to clear a 24x24 construction site, with an 8' high bank on the uphill side. For remote sites this machine has proved to be tough and capable. It's taken more than its share of abuse and it's going strong.
thanks again, D Palmer


Here are a few pictures of the backhoe. The plans are well written and I've been able to get through it without a lot of confusion or mistakes. I really appreciate your good work in cutting and drilling the materials. The pictures with the plans help a lot in picturing how things go together.
