Best way to dig out crawl space.

Ok so I need to dig out a ton of dirt in my crawl space. The house was built in the 50's so the dirt is almost to the joist and I'm trying to get it spray form insulated. I brought home a vac truck from work (giant 4" vacuum hose with 500 gallon tank) so I have a way of getting the dirt. I'm just not making any headway digging.

Any suggestion on power tools to help me? I was thinking a electric rototiller ( if I can find one tomorrow), like a hand held jack hammer (can't remember the correct name).
Any other suggestions. I can only use the vac truck on this weekend and I need to make some progress

Turn some gophers loose?

Do you literally only need to excavate one ton of dirt or are you going down? If you wanna spray it you're gonna need some room.. What's your point of entry, a coal chute sized door from outside or trapdoor in the floor inside? What kind of substrate are you dealing with... clay, shale, etc?

If you can get in from outside and dig a small 'cave' you might be able to run a rototiller horizontally and suck it out. Dunno, more info?

I have a 18"x18" door on thw out side. I have 3' at the beginning and tapers up to the floor. I just need a 2x2 or 2x3 trench around the exterior wall. My idea was lay an electric rototiller down and push it in to the slope but its winter here. Cant find one new.

Soil is clay but not super hard. I tried to dig with a small trench shovel but digging on your stomach or back doesnt work well. I actually used a claw hammer and it worked pretty good. Just took for ever.

Any way you do it it is going to be some real work to get it done.

If anything a small folding shovel might work the best, try the surplus store on west North Ave if it is still there. If they have the folding shovels I would get a couple of them just in case you break one. If it is fairly dense like clay is a electric demo hammer from Home Depot or a rental shop might work. Also while you are down there and if it hasn't been done before if you know, get a radon test kit. A lot of the older homes in the Junction area have a problem with radon.

I had to dig a trench under my home for a new water line a couple of years ago and by the time that I was done digging a 3' deep trench 10' long I was ready to give up and I could sit upright in the space.

If it's that hard packed it sounds like you're gonna have to 'jack it... I do not envy what lies ahead :O

At least you can suck it out, no 5 gallon buckets in your future.

Hey, random dart... Any chance you can staple some plastic to the floor (upside down work but...) to limit collateral mess and just let high pressure water do the work while the Super Sucker suction line lays near ground zero?

I like the water blasting idea... earlier you said you couldn't find a rototiller, what about a post hole digger? Throw a shorter bit on so it's manageable and then strap on a back brace and go to town...

temporary labor, you need some help man!
Digging in CO in winter

This is why I have step sons :) Gotta get 3-4 dudes on a project like this
No real easy way about it, we always used pick, heavy bar, small folding metal shovels and buckets/tarps for crawl spaces like this

Doing that kind of digging is what real work is about, I'm glad that when I think about doing something like that I soon forget about it.

In the meantime take a trip to rental yards and see what kind of dirt digging machines that they might have for rent or even talk to contractors or dirt moving contractors that you might know and see if they have any ideas of what could help you out.

Sounds like jackhammer or rotohammer and a spade digging bit.

Sometimes the hard way is the only way.

That is unless you hire it out and then you can just sit back and drink coffee or your favorite adult beverage until it comes time to sign the check.

Dayyummmm, blast from the past. Got a 1950s Traxcavator sitting disabled in the boneyard, the clutch to engage the pony motor to the diesel motor is too far gone to spin it when you lock it into compression selection. No clutch/brake lining place I've asked (and I've asked a lot) can or will do it when I give them rough measurements and explain how the rivet holes kinda 'oblonged' themselves.

Talk about a strong digging machine tho. I've never seen hydraulic lines erupt with so much force and volume of fluid as that prick would let loose with.

My vote is on hiring Mexicans. I was going to suggest hiring local kids to help out. But after a little thought I figured that would be a waste of time! As kids now a days dont know what work is!
