What's the difference in lifting capacity between 1100 and 1400-1500?

@Vigo, That's a great point about the backhoe increasing the overall length. I've also decided that if I buy a backhoe, it'll be a dedicated/integral machine (such as a Terramite), not an attachment. I don't see how much benefit there is to a GT/SCUT-sized backhoe attachment. However, a small machine with just a loader definitely would get used here.

In my case I’d be going from stock (around 950 psi +/-) to 1400-1450-ish psi. That’s a nearly 50% boost and would probably increase lift capacity by almost as much. But it would also increase “squeeze” capacity significantly on the 3PH logsplitter. 👍

The modern SCUTs have a much easier/quicker mount/dismount for the BH (and FEL). So re-configuring is pretty simple and fast. It’s not like the older machines where it made sense to have “dedicated” machines for certain tasks, due to the hassle of reconfiguring.
 
For me, the digging depth (and strength) is more important. I have mature oaks and large boulders that need to disappear. I struggled to do that with a rented Terramite in the past.

I get the impression that SCUT backhoes are good for planting bushes and digging shallow trenches. Assuming no large buried boulders get in the way, of course.

Lou, 1100 psi says to me someone shimmed it a bit previously. Or you just got one built on a good day! [emoji23]

@LukeL, 1500!? Whoa baby. Is it behaving alright?

P.S. I’m targeting around 1400 when I do mine.
I put my X495 with 45 loader at 1500 PSI as well. Makes a huge difference. But probably not too much different from 1400.

I couldn’t find any specs for the Terramite. But I have seen them in person and didn’t get the impression they would be more powerful than a SCUT. In fact, I always assumed they were a step down or at best a primitive version of a SCUT.

For large stump removal you either need to be very patient or go BIG. And I mean MUCH bigger than a Terramite or SCUT. I have watched large commercial backhoes struggle to pull stumps. I have also seen how folks with SCUTs can slowly work around a stump and eventually get it out, with abundant patience/time.

If you are looking for something that is a dedicated TLB, with a fair bit of grunt, but not too huge, watch for a Kubota B26. 👍
 
Terramites come in several models, but two basic sizes. T5 and T7 are the smaller size, T6 and T9 are the larger size.

I believe that I rented a T6 (the rental center is no longer in business).

Here's a link to a spec sheet for the T5C:

Here's a link to a spec sheet for the T9:

Here's a link to a Kubota page for the B26. Interestingly, they have a model comparison sheet here as well, and the B26 compares closely to the T7:

I’ve always thought they were pretty neat. Looks like they have been continuously improving them. 👍

Back to psi and shimming… I finally got around to testing the X748. Seems I have similar readings to @LouToolGuy. Here is idle and operating rpm:

I read it as 950 psi @ idle, and 1050 psi at operating rpm. So

As an side, this is my first time unboxing and using the pressure-tester from Aux-Hydraulics. What do you guys think of that air bubble in the glass? Is that normal? Seems huge to me. I find it pretty irritating to read the gauge with a bubble that large.

Yes you never know where a thread might meander. 😜
Yes John that looks very normal. Are you going to see what shims you have to start or just shim it? Have you tested the 45 Loader yet? You owe it to yourself to see the difference after shimming, otherwise you might not appreciate it as much. IMHO

Lou, I have not tested the 45 FEL yet. I hear you about testing the difference. But I have decided that I am going to shim when I have the fenderpan off for the THRV installation. And I am doing that at the same time as the 3PH (and rear PTO) installation.

I could briefly slap the 45 FEL on prior to that, but without the 3PH/Heavy Hitch rear ballast combo, it wouldn’t be much of a test.

And like you, I have a cab. I really just want to get everything taken care of all at once before the cab goes on and removing the fenderpan becomes a hassle.

So I am just going to go all in right from the start!

That makes perfect sense to me👍.

The air bubble is normal, but I removed the plug from the top of mine and filled it with glycerin. It still works fine and looks way better!
 
Thanks guys for the feedback on the air bubble.

@LouToolGuy, I will let you know if there are any shims in my IRV when I dissect it. I assume it is stock, but maybe stock includes some shims anyway? So I’m not sure if I will be able to get a definitive answer.

Since I’m at 1050 psi already, I’ll probably aim for 1450 or so.
 
Based on other threads, it seems there is a 300psi per mm increase. You want to go up 400psi so that would mean adding 1.3mm. If you are using 0.2mm shims, six would be about right. Normally there is already a shim or two there, sometimes one is a odd number so you can remove it and replace it with an even numbered set to get that last 30psi.

Thanks for that info. I ended up adding 1.4mm of shims, plus the two factory that were there. Nailed it at 1450 psi:

Congrats on the pressure mod! Im going to increase the pressure on both the Kubotas i mentioned earlier. The b6100 is a bit of an oddball because it uses 2.5” cyls and only 750psi (tested), which means it has a lot of parts-breaking potential if it put it up to an otherwise normal sounding 1500-1700 psi.. 😳

The b8200 spec is 1700 stock but i havent tedted it. It uses 2” cyls.

I agree that a mini excavator is far superior to a scut backhoe, even more so in tight spaces. However, while i’ve used a mini ex it was a much larger class than a scut (dont know the ‘ton’ rating but it weighed probably 8k lbs) so i cant say for sure that the capabilities dont fall off to ‘frustratingly weak’ when you get down to the 2-3000lb machines. The videos ive seen make it seem ok..

My backhoe i would say is on the weak side but i have dug up many large rocks with it. It does not have a lot of strength when it comes to ripping through roots. Im gonna crank that pressure up too.. 😂 The main frustration i would mention from my little 6.5’ backhoe to the mini ex ive used, is the lack of reach more than anything. I feel like a 7.5-8ft reach would feel like all the difference in the world even if i never actually dig an 8ft hole.

But the backhoe is almost irrelevant to the OP’s property.. but i could see making a little use of a tiny stump bucket like the kind Good Works Tractors sells. 👍
