How big an excavator?

[RAW]

So, what machines do you recommend for running the 050 and 060 heads?
And how much do those heads cost?

I don't know all the different models and specs but if you'll take a minute and look at our website you can pick a excavator from the specs. I personally like to go up one size when I find a fit to insure a good balance between tractor and head weight. Also some excavators have better hyd h.p. than a competitive size.
As mentioned on the thread attention Robbie and Fred we have the DAH-125D which is the next size up from the unit we demoing now. CB was looking at the 100h.p. range. That range has good stability and hyd flow.
I will work on a small list for the 050 thru the 125D range and get back to you.

Yeah, in my original plan, I wanted to get a compact excavator (like a Kubota 161) . . . but I ended up with the Antonio Carraro tractor with carbide mulcher instead.

One of the factors in that decision . . . . talking to several different equipment suppliers . . . it became evident that some manufacturers of machines are optimistic in their claimed stats. And then some machines appear to match all of the specs for a particular piece of equipment, but . . . for some strange reason the machine won't handle the weight or balance of an implement very well, where another manufacturer's nearly identical carrier will handle it fine. I just got discouraged and irritated trying to find that info a few years ago.

My hope as these implements become more popular for excavators . . . is that good manufacturers will run their implements on several different carrier brands and be able to provide customers with detailed feedback.

The demo we are conducting is here in McDonough. You are welcome to come. The official date is Monday at 9 a.m. but I live very close to where we are keeping the tractors so any time this week I am available. To see one of these units in action is awsome. My cell number is 404-379-5897 if you need or want.
The factory has a very comprensive list of what we have installed heads on so we know exactly what works and how well it.
Side note. How do you like the carraro? What head are you running?

RAW - Which Antonio Carraro model do you run? How much PTO HP? I may be in the market for one for maintaining previously mulched areas. (orposibly adding to the mulching fleet) It looks interesting, especially the low profile and ability to be bi-directional. I was also looking at the New Hollands.

Quick BTW I was not trying to Hijack . As far as how big an excavator, I hope my new Kubota 080-3 is big enough to keep up with the skids when I get the Cimaf head. I will let you know what I think as soon as I can. I may even take Robbie up on his invite if things work out in my schedule this week. I am a little skeptical but seeing is believing! If it dosent perform there may be one more low hour Kubota for sale! Although I may need a bigger tow vehicle if I go to a 12 ton machine..

I've got the TRG 9400 with cab.
The engine horsepower is listed as 83 hp.

I'm not sure that I'm quite ready to sell it. I've barely been able to use it yet! I've only put about 12 hours on it, myself. The "front" tires are off getting foam filled. Then they'll all be done and ready for serious use.

Though if I see Robbie's excavator and implement in action . . . I may decide I've gotta have one!


And those New Holland bi-directionals are great. Too bad they're so darn big (and expensive).

I've been in touch with the AC people too. I was looking at the TRH with the hydrostatic transmission. I wasn't sure how mulching with the other models would be having to switch gears all the time. I've been to the New Holland dealer too DW

I'm looking to change all my machine, looking for a better combination....

I need the tractor for some right of way mowing too.

RAW,

As seen on our website but with extra comments, here's what our recommendations are for our different models:

DAH-150E:
Our most popular model yet. Okay for 20- to 30-tonne excavators. Has been installed on pretty much every big names so far. One was installed also on a CAT 315 with a power pack, but that's not common use.

DAH-100E:
That's a short version of the DAH-150E. Same heavy-duty frame. Recommended for wheeled excavator 18- to 20-tonnes.

DAH-125D:
Replaces the DAH-060. Ok for 12- to 16-tonne excavators, or bigger if the machine will not be used to push the excavator. I wouldn't be comfortable to put a DAH-125D on a 20-tonne excavator knowing the operator would use it to push himself out of some places. But on a 20-tonne excavator on wheels, to work on roadsides only, I'd have no problem.

DAH-050:
We'll probably keep this one for 10- to 12-tonne excavators, even ok down to 8-tonne. Has been installed on Yanmar 75 in the past, but a bit bigger wouldn't have hurt. Was ok on Komatsu PC78.

DAH-080C:
That's the new baby Robbie is trying this week. So far, the Kubota 080 seems ok. I'll want it to be tried on other models and other brands after that, so we can see how small an excavator we can go. I think we'll be ok in the range 7- to 10- tonnes. Not sure we'll go smaller than that, though...


Uh-oh, maybe I should have written that in thousand pound instead. Sorry, I was born metric . Here's a quick, approximate conversion table:

30 tonne = +/- 66 klb
20 tonne : 44 klb
18 tonne : 40 klb
16 tonne : 35 klb
12 tonne : 26 klb
10 tonne : 22 klb
8 tonne : 18 klb
7 tonne : 15 klb

Of course, the recommendation are approximate. This rule of thumb is not exact science. For an official recommendation, I usually check:

1- what's the hydraulic capacity of the excavator?
If total flow x 0.4 is over or close to our minimum flow recommendation for one particular model, we are usually good. If looking for an excavator on which we never have installed a machine, the best is to obtain flow charts to see more in detail the kind of flows we get at different pressures.

2- what are the lifting capacities of the excavator?
In the spec sheet of an excavator, there are usually lifting capacities charts. Looking at max reach on the side, if capacity is close to be twice the weight of a particular model of brushcutter, we're good.


Hope this helps,
