I've got some acreage in central Maine and I want to start building next year, and I want to do as much as I can myself. I'm debating whether to build on cement piers or go with an insulated slab. Both have pros and cons for building.

What this post is all about is whether one of the one ton machines are capable. For the piers, I would need to go down somewhere between 4 and 5 feet. I figure at least a foot of dirt is going to be scraped away first, so the mini would only have to go 4 feet down at the most. One of my neighbors up there actually spent all summer a few years ago digging the holes by hand himself. I'm almost 70. I don't want to do that and I don't want to spend that much time. I hope to have the place at least dried in by snow time, so like a year from now.

Now the slab is something I know a lot less about. I would need to do more research to see what I would need to do. I know the basics for the ground prep.

Oh, and then there is the septic. That hole for the tank might be a bit much for a one ton? I see the leech field as no problem.

There is no question that the machine would come in incredibly handy after the house building ground work is done. The land is undeveloped and had some cedar logging done about 20 years ago, so there is a lot of clean up to do for putting in gardens, fruit trees, just having nice areas, etc. However, for the sake of this post, my ultimate concern is strictly cost effectiveness. I can get a machine from someone in Ellsworth, Maine who is advertising upgrades on a "1.2T", whatever that really means. The important bits are upgraded lower chassis (longer and wider), hydraulic thumb, ripper, rake, and counter weight. Just under $8K for a new machine. I'm using it as a reference point for what is out there.

There is also no question in my mind that it will pay for itself compared to hiring out. Plus, I will do it the way I want it done, not the way the excavator thought it should be done. That's already happened with the driveway I had put in. Don't want to do that again.

Do you think this is realistic, or will I be under gunned? Thanks for any info and/or advice.

Of course it would eventually get the job done. Shovels used to be the only way. But a 1 ton is pretty small for the work. A bigger machine would be a lot better. For the septic you really need a bucket as wide as the leech field. Trying to dig a wide ditch with a narrow bucket doesn’t work well.

Check for stone!

One issue with any smaller machine is how far you can reach to dig. Sometimes it's hard to reposition the machine if you can't reach far enough from one position.

Cal G is totally right about stones. Large stones (or tree stumps) can be show stoppers for smaller machines.

Where I live you don’t have to check you can just assume it’s there. Maybe 50 ton excavators with rippers can break bedrock but it’s pretty much a showstoppers for any machine.

My friend used his BX series Kubota back hoe to dig for his self install septic on his land in Maine. Not sure how long it took to dig it out. Passed inspection so he did something right. Point is it’s a smaller digger as well so it’s possible , hopefully no big rocks or ledge.

I understand wanting to do it yourself. I also own a 1-ton mini ex bought last August. Based on my experience I would say it was unrealistic for someone at age 70 to master operating one of these good enough to accomplish what you are asking of it unless you have a background in machine operation. Even a younger more experienced machine operator could find the mini insufficient to the task.

In good soft soil without large roots and rocks it would be doable but hardly anyone has that. In my opinion you would not get back what you pay out versus a professional with proper equipment.

That said if you want a machine for occasional digging and trenching tasks the mini is handy to have about. The Chinese minis are light duty, cheaply built and have virtually no resale value. They are also incredibly slow to move around.

Here on my property I would never use my Kubota M6040 for house foundation or septic installation.

Two main reasons. Solid basaltic lava is close to the surface. My house footings sit on this bedrock - after three days of hydraulic jack hammering to level everything up. My septic tank ( concrete ) sits on a foot of sand that sits on this bedrock.

And - my lack of experience. When we came down from Alaska in 1982 I had never sat on nor operated a tractor. Any bravado or macho I might have had, at that time, certainly would not make up for lack of experience nor equipment availability.

I’m not sure anyone ever masters a Chinese excavator. They’re very rough and jerky. But someone could get proficient on a good excavator probably within a day.

A one-ton mini ex in the rocks and boulders of central maine? Don't do it. You need a minimum 3 ton mini ex or ideally 5+. You'll want something that can pull an 18" or 24" wide bucket with power.

OK, sounds like the consensus is that it's just not enough machine to do the job. As far as roots and rocks, we're talking about quaking aspen and smallish big tooth aspen. They've grown over the clearing where the cedar was harvested. As far as rocks, I don't know what is considered to be too big. There are certainly a lot of rocks, but nothing I haven't been able to move myself when cutting and stumping the aspen. Oh yes, I did that all myself with a mattock and a small chainsaw. Talk about back breaking work, but I cleared over half an acre without having to pay thousands of dollars to an excavator. It took me a few weeks working 4 to 5 hour days.

So if it has to be slow, that's OK with me, but if the machine just can't do it, well, that's the deal breaker right there.

Thanks to everyone with the feedback.

I would spend the extra and get a 4 ton, give or take. You will thank yourself every time you use it.

Stones are surprisingly heavy for their size.

When our house was built about 18 years ago I had to put in my septic system myself if I wanted to move in in less than 6 months. So I bought a Case 580CK backhoe even though I had zero experience with backhoes or even tractors. To excavate the ditches for the infiltrator type system I had to fabricate a blade that went over the hoe's bucket teeth to give me a 40 inch wide flat blade to make the flat bottom ditches. I did all my digging in sandy loam with tons of rocks. After the septic system install I dug all sorts of ditches around the place, dug up several alder stumps and put in two roads. The Case will dig a ditch 16 feet deep max, at least that's the max reach of the hoe. It is not a light machine. But the hoe really moves the machine around. I would not want a light excavator unless I was only digging 6 inch wide ditches no more than two feet deep, and even then only in easy to dig soil.

I have a Takeuchi TB 235 and I wouldn't want anything smaller that that. I may trade next yr for something larger

It wont do your job. You are looking at a 450 Deere or 892 which is an older model. 225 Cat MIGHT do the job.
I am putting in field tile here in central Illinois where diggin is S'POSED to be easy with a AGT L-12 and at 4' your maxed out on depth. Only way to go deeper is to bench down.

when we built the house I planned doing trenching for power, gas and water myself, had access to a small mini thimk it was a 1 1/2 ton, had to trench 1/4 mile and 3 days couple hundred feet went to auction and picked up a Cat 420D backhoe, 2 days later had the water, gas and electric done working on septic, right tool for the job.
since purchased a Bobcat E32, be around the 3 1/2 ton, it has prover more than capable doing piles, screw piles, root removal, landscaping and tons more but could not see that small machine capable of doing the work regardless of the time it takes

A 5 ton mini could do any of that. the issue may be if you hit any big rocks that it can't pick up. i had a KX121 Kubota and was impressed with what it could do. Sold that and bought a new Bobcat E35 long stick.. Its not as powerful as the KX 121 was but its more comfortable with heat and ac...

3,500lb machine. This is my septic in the northeast. Notice the large rocks on the right. 2hrs to dig 80' of drain line 2days to dig the last 20' of the 100' run. You can bent 4in pvc if you really need to. I had to dig that trench wide enough to get the machine down there and build a ramp to pull out that large rock.

I also put a 1,000gal tank in, I just did a light step dig. They also sell low and wide tanks, this wasn't one. I have a 12" bucket and used 2'wide leach chambers. Yes a 2' wide bucket would have been quicker but not a deal killer.

The trick with a small machine is to think and plan your dig.

Rocks, yeah I grow those things here too. Was your machine able to move those larger rocks, or did you have to use something else? Been tossing the idea of a mini for here and no idea where to start size wise. Thanks
