Backhoe The great backhoe dilema

RyanC · Aug 6, 2004

I (like many others it seems) am pondering the difficult decision to make the "investment" in a backhoe for my JD4200 (26hp, 4wd hydro,72mmm,FEL).
The two major jobs for which I am trying to justify the purchase are:

1) Waterproof my existing basement.
My wife and I would like to finish off the basement, but it is not currently the most flood-free. I would like to dig around the perimiter, seal the walls with a Firestone pond liner, and lay new foundation drains run off to gravity drain. This is a standard 8' basement with a perimeter of ~140'.

2) Build a swimming pond with stone waterfall.
This would likely be about 20' x 30' x 8'dp (bowl shaped).

The question is rent? or buy?
Can a compact LBH do the jobs I want? If I rent, it could be mini-excavator for basement, and full-size LBH for lake.

I would really like to be able to justify a new hydraulic/testostorone powered tool/toy, but $7k+ for a JD 47or48 is not an insignificant purchase for me. Especially if it can't do the jobs mentioned above.
If a compact LBH can do my projects, what does everyone think about some of the ~$3-5k priced hoes? Is Green worth 3k more green?

I've been reading posts here for a while, and you guys are great! I hope that someone can offer some wisdom which will clear this up for me. /forums/images/graemlins/confused.gif

That's a lot of digging for a small backhoe on a small machine. I've had a backhoe in that class before and I think you'll be it at for many days. I also think you 'll have to dig a ramp to get the depth you need. Notice I didn't say you couldn't do it. Just would take some creativity and patience. (and hope you don't run into anything big)

"1) Waterproof my existing basement...."

That's mighty close to the house for an inexperienced back hoe operator! You could do some serious damage during the learning curve.

For both projects you mention, it'd be cheaper to hire someone to do the excavation work or rent a machine.

Of course, you would be able to do the backfilling with your 4200.

And, working in a deep, narrow trench isn't for everyone. That can be a very dangerous bit of work without the proper shoring and experience.

I agree with the others, doing either with the CUT hoe would be doable but on the end of not really worth the effort cosidering the initial cost of the HOE you coul dhire it done and not have to do more than pop the top of a beer. /forums/images/graemlins/smile.gif

A CUT hoe will be miserably insufficient for big jobs, but could be done if you can find one for your tractor that'll dig 9' flat bottom.A lot of guys buy a 10-15K good used TLB and do the projects, then turn around and sell them- sometimes even at a profit. Need to know what you're buying though.

For the job of digging around the foundation, I dont see how you can efficiently do it with a CUT backhoe. You need a mini trackhoe that you can offset the arm so you can pull it right up against the wall and dig from there. You will have one heck of a time getting up against the wall with a tractor without causing lots of colateral damage to the rest of the yard. If you havent operated a backhoe before, be aware, there is a learning curve. Figure at least one day you wont do much valuable digging until you get used to it, especially in close quarters, like up against your house.
A tractor backhoe is better suited for the pond but it will take you awhile and when your done, you will be more comfortable on the backhoe. That would be a good learning project. If you need it done by a certain date, get a full sized backhoe in there and get it done. I know, I just finished a job at my neighbors house that was too big for my little backhoe. It was frustrating because I felt I was just picking at it. In retrospect, I should have bit the bullet and rented a mini excavator

Ryan -- As a backhoe owner myself with a couple of years experience and enough finesse to use the hoe for picking up after the dogs...I still have to agree with the others. With the outriggers down, the hoe would be at least 3 feet away from the foundation, so forget about a nice trench with neat sides; you'd be forced to nibble away the entire length of the house. A mini excavator or (not sure of the dimensions of your walls) a big sucker with enough reach to do the job from one end of the house, would be the way to go. And my vote would be to hire the job out.

For the basement the trench is deep enough that either it should be shored or backsloped to avoid cave ins. A larger hoe working with the dipper is much better suited for this job. As others have stated, contract this portion out as it's serious work and requires operator skill.

For the other portion of your projects it's a question of which takes your fancy. Spend money on equipment and do it yourself or rent a large machine for the job.

Perhaps price out the house work first as that is important and then go from there.

Remember the drainage should have granular material and the trench backfilled in small lifts and compacted. And if a trench is involved make sure proper shoring is in place as back fill around a basement may not be stable material.

Ryan, I am a long time and vocal critic of smaller tractor mounted mounted backhoes and usually I take a lot of grief for my position. As there is a Kubota B2910 with Great Bend backhoe at my disposal 24 hours a day, I can tell you I just dug a 40' by 4' by 4' trench in June of this year, to rebuild a retaining wall and I did it with a rented mini-excavator in one easy afternoon of work. Had I used the smaller tractor mounted hoe, I estimated it would have taken full 3 weekends and several evenings to do the same job. The rental fee was under $250, it was delivered at noon Saturday and picked up about 8am Monday; I was done before dinner Saturday evening.

Build a swimming pond... 

I don't think either of the jobs you have are great candidates for a small tractor BH. Perhaps you could excavate the pond with a small BH, but the time consumption would be enormous. A 47 BH won't reach down 8', and I don't think a 48 hoe will fit on your tractor. I believe the 48 just barely gets down to the 8' depth range, anyway.

I had the pleasure of watching a pond about the size of yours being built a couple years ago. The pond is next to the road I drive along to work every day. The tractor was a Ford/NH and looked to be about 60hp. Only a front loader was used. A dirt ramp was used for the tractor to get into and out of the excavation. The project went several days before the digging was finished.
