Newbie mini ex questions, and Kubota KX vs U series?

[WVH1977]

I just got myself an excavator about two months ago. It is a Hitachi EX100 and is 24000 lbs. I was a little intimidated at first because it was big to me. I have rented mini-ex's in the past for clearing land but they were a lot smaller. They got the job done and are really nice. I think the ones I rented were around 14,000 lbs.

Now that I have used this new to me excavator the size is not worrying me any more. I have cleared tow spots around my house about 1/4 acre and the ex made quick work of it. It would have taken twice as long with a smaller mini-ex. The only reason I bring this up is you might be able too find a better deal on a bigger machine. You can use it and when done resell it.

I still want a mini-ex!!! I am always dreaming.

As a guy who bought a KX040 a few years ago. I can say for sure, I wish I had more reach. Working in trees I have to be careful not to swing into a trunk, but other than that I am happy with the standard counterweight. If your cutting trails in slopes that might be deep enough for a counterweight to hit, then consider the U.

So I got some pricing back from the Kubota dealer.

The KX033 is well out of my price range, so I've been trying to decide between the U25 and the KX018.

I was leaning towards the KX018, as I don't need the zero-tail swing, and I was expecting the KX018 to be considerably cheaper than the U25, but they are actually about the same price (in fact, the KX018 is a couple of grand more expensive than the U25!).

This seems strange to me, as the U25 is 1400 pound (700kg) heavier, 8" wider, has 1400 pound (700kg) more breakout force, and 7 inches more ground clearance when compared to the KX018. So it sounds like the U25 will be much better at doing the kinds of things I want to do, yet is at a similar price point to the KX018.

So does this make the U25 a no-brainer then? I don't like the U is set a bit higher (more tippy), and the zero-swing compromises the power compared to an equivalent conventional tail swing, but in this case I am compelled to choose the U. Given the extra weight and width it would have to be more stable on slopes regardless.

Am I missing anything?

A few years ago I had similar questions of the u25, u27, and the kx, back then if I remember correctly it seemed the u25 had automatic high speed meaning when it was sensing little resistance the drives would engage to higher speed without pressing a button. I asked a Kubota sales rep at a show why the U series quotes I got were so much less than a comparable kx the response I got was vague but I believe it's partially due to different hydraulic pumps and motors, more hydraulic capacity? But without having the actual components or specs in front of me to compare I'd like to know before choosing Kubota. I believe the kx 18 will be limited in possible future attachments it can handle. Good luck

I am assuming your are going to finance this? If you are able to pay cash, you really might want to consider on older, cheaper, bigger machine. I am all about buying new but for construction equipment, used might be the way to go if you can get the money together. You are already concerned about size, weight and power. if you get the smallest thing you can afford new, you might be disappointed and stuck with big monthly payment that will keep coming.

I am not sure how much these machines are new, but I am guessing $ 40,000 dollar range. That is going to be around $ 560 a month for 6 years. You state "budget is fairly constrained". Just throwing it out there as I am sure you already know all the numbers. I have financed big purchases in the past knowing I would have a big payment and did not truly need it but justified it in my mind and took the plunge. I am really trying not to do that anymore. Especially right now with the way things are going.

You have 3 big projects listed. If you rent for say 2 grand for a week each time over a two year period, that is only 6 grand. Get a good sized machine and knock it out. Just something to think about which I am sure you have already thought about.

It is a big decision. Good luck.

Another thing to consider is maintenance imo. I have two old Kubota tractors and some other stuff is John Deere, it's nice some filters and all fluids are interchangable on the older Kubotas, . A John Deere 26 G mini takes special zinc free hydraulic fluid at over $200 with discounts for five gal and you aren't supposed to contaminate it with anything that has zinc. It will take 10 gals plus all the filters I believe for pms. In comparison a JD 326e skid loader comes from the factory with 10w30 diesel rated motor oil for the hydraulic system, per manual.
Just other things to consider IMHO.

Thanks WVH and jjeff, you make some sensible points.

I actually asked the dealer about the similar pricing and he came back with a very vague answer too, it seemed he really didn't know.

@jjeff and others, here's a complete comparison of the two:

We've got about 3 acres of billy goat country (undulating and frequently steep).

My list of things which I need to get an excavator in for keeps growing and growing, to the point where I'm now thinking I might be better of just buying one, even if I end up selling it on again in a few years once we have the property mostly the way we like it.

The kind of work I want to do:
- create terraces down the hill side (by cutting and filling)
- maintain/improve our dirt and gravel driveway
- dig trenches

Budget is fairly constrained, so I'm considering the minis at the lighter end of the Kubota offerings (0.8-2.5 tonne).

First question is - are the lighter machines I've mentioned going to cut it? I've heard that you can do almost anything with a smaller excavator compared to a larger one, it just takes longer....which I'm okay with. Is this true though? Will the 0.8 tonne KX008-3 be able to get about my property ok (it's 20 degrees in many places), or are these smaller machines much more prone to tipping on slopes compared to larger models?

Do I want the KX or the U series? Is the KX going to have better stability of my slope land? I heard that the U series tend to be more tippy because they had to raise the centre of gravity in order to make them zero-swing. Is this true? If so it sounds like I definitely will want the KX since zero-swing isn't a priority for me. Is there any other reason to choose the U over the KX?

For 3 acres, maybe. Trenching no problem unless you hit rock. Cutting in a hillside will take awhile with a super small bucket, but its fun work and you can do it. I would not count on getting much done fast on a driveway with a really light machine...get as much weight as you can.

Also those really small Mini-Exs are REALLY tippy. Easy to turn them over. Careful on hills and take it slow. The are made to get into tight, flat spaces. So they arent very wide.

The big difference is weight and hydraulic flow between the 2, the u25 has more of everything , why it's less I have no clue. Did you get a quote on the U27-4? I was quoted on the U25, U27 and the comparable kx series several years ago wasn't much difference in price between the minimal swing u models. If I didn't want higher auxiliary flow and still wanted new for a non commercial setting I probably would have settled for the new nortrac mini just for trenching and cutting a hill side they also have a lot of accessories. you can buy 2 nortracs and all the accessories you can ever want or need for the price of 1 Kubota or deer bone stock. With minimal tail swing on a JD 26 G I can lift and swing 1400 lbs if I'm aware and careful plus on jds anyway I can get a bigger counterweight if I feel I needed it which I don't, it would just reduce tail swing clearance it's bolted on with 2 bolts I believe. imo minis have a low center of gravity decent counter weight and using the blade helps a lot for stability when booming out even on the sides imo. If it was me choosing I'd get the u 25 or 27 model. Good luck.

Ok I'm getting close to pulling the trigger on the U25, just wanted to check what y'all recommend for a very basic set of attachments?

Was thinking to get the following:

18" (450mm) dig bucket
a 3' or maybe 4' (1200mm) mud bucket
Single tyne ripper (for digging out stumps, breaking up hardpan)

I have a heap of 2" irrigation pipe to lay so I was hoping the single tyne ripper would do the job, but I might be a little optimistic..?
