Question about hydraulics performance on different excavators.

I’m good with it!

No ideal what numbers you are talking about..4200, 2900?
not in cdl territory, well under. You keep saying less capable..I’m quoting kubotas stats. At best you could only say they are equal, but in reality the u48 has more numbers on top of the 040. Please explain.

Well if you look at the 2 pdfs I linked and look at the lift capacity…you will see 4200 Vs 2900.

Lift capacity? Look at your stats again. The KX is 4200, U48 is 2900. Not very close. The U48 is a great machine…I almost bought one over the KX040. However when it came down to it there was no reason To spend more money for a less capable machine for my needs.

So you are into CDL territory for what? Not really any gain. That was my point.

oh man, I just realized what your talking about… those charts. Lol

Those charts aren’t even, you need to look at them closely. The 040 chart starts at 8’ out from machine and the u48 starts at 12’.
Kubota stopped listing the the 8’ on the -5’s. But I saw some literature can’t remember where but the up close lifting capacity of the u48 was like 5200.
Again, look at the charts. The u48 has more lifting capacity on almost all comparable measurements. It is weird dealing with 2 different charts. Confusing right?

Supposedly they just split like right now. Who knows why, and all Deere minis will be 100% Deere unless they split with hitachi to go with another manufacturer….like sany. Dont laugh, Deere is about the bottom line.

You know Deere's little tractors are Yanmars, or at least powered by them. They have had a long relationship together. Kinda wonder if they'll use Yanmars minies?

I thought that I heard or read that JD has split up with Hitachi.

In the past the deeres were definitely Hitachi's but recently they announced they were splitting up.

I've always heard Airman made the JD mini excavators 50 and smaller

Deere & Company, Hitachi to End Joint Venture Agreements

MOLINE, IL (Aug. 19, 2021) – John Deere (NYSE: DE) today announced it has agreed with Hitachi Construction Machinery to end the Deere-Hitachi joint venture manufacturing and marketing agreements.

When I was shopping mini excavators I had checked out the Deere 17g and then called the Hitachi dealer. He didn't have a zx17u on the lot then asked me if I looked at the 17g yet, I said yes, he said it's the same thing but in orange.....

Useless observations or speculations below.

Last summer I rented I think a Deere 27D. It had a Yanmar engine. The 35D also has a Yanmar engine. Even the 17D has a Yanmar engine listed. I did not look around on the rental unit to find the country of origin or assembly tag. I see Hitachi has mini-exs with Yanmar engines. I guess Yanmar is a popular engine. My little JD870 tractor is made by Yanmar.

I am forgetting the size of the CCA timbers we placed. I think they were 6x8x16'. Kind of exciting spinning 180 degrees if you have the boom out too far. Just like a loader, keep the load low and close to the mini-ex. I can see why some folks might like to use that boom extended a bit moving weight around.

I need to do some french drains around the horse barn. Maybe this year. The little mini-ex I rented seem to work fine digging and moving gravel around. Might be a bit more challenged digging dirt. If I start that project I will let the rental yard tell me what I need.

I still won’t be surprised if Deere split with hitachi to use someone else cheaper to build small mini’s.

Well if you look at the 2 pdfs I linked and look at the lift capacity…you will see 4200 Vs 2900.

I made it simple for you. U48 out performs kx040 on lifting in every comparable measurements, charts are not equal, you have to pay attention. As I said earlier, I read on some press release that the up close craning is like 5200lb for the u48, compared to the 4200 of the 040. The only place the kx040 outperforms the u48 is 6” in dig depth. The tracks are 1’ longer and wider so much mor stability. 32gpm flow through 3 pumps compared to 24gpm single pump on the 040. The u48 is more machine. Even a longer stick by a few inches. Down side is the angle difference of boom that changes dig depth because of the length of the undercarriage I assume, in which a grinder may fix.
