Backhoe BH75/90 backhoe owners- survey

[txdon]

I have the BH90 - no problems in over two years. I have dug ponds and stumps and have removed tree limbs and moved bridges.

I had the BH90 on my old 3830 and transferred to it to my new to me 5030. I have an 18" and a 36" bucket. The only trouble that I had with it was that for just one day the main boom arm wouldn't stay up by itself. When I went to use the tractor the next time, though, the problem vanished. I wonder if a spool valve got stuck or something. I'm very pleased with the BH90.

Had BH75 on a L3400. I was very happy with it. Seemed strong for size and controles smooth and easy to use. Dug out a number of pine stumps and boulders, trenched and general use with no problems. Traded in tractor for L39 after about 50 hrs but hoe was not reason.

I can't say I've heard of an abnormal amount of problems with these. The 75's did have the dipper cylinder upgraded, that was a known issue - but the BH90 has been on the market for a long time with no abnormal failures rates that I've noticed. We also sell Woods, Bush Hog and Bradco backhoes and I can't say that we see one brand holding up much better than the others. There are feature and performance differences between them, but I'd not say one is more reliable than another.

this is my first hoe so all the suggestions help, originally i was a little puzzled when i've be seeing different posts on bent cylinders on the BH75. I know you can overdo it more easliy with the smaller hoes like mine and have to follow suggestions been gettting. I guess i expected to see some posts on other smaller hoes like on the BX since its smaller yet but have not seen any. But any way everyones suggestions help thanks.

I've worked the BH on my BX23 pretty hard without incident. I routinely hear the pressure bypass working whenever the BH hits an immoveable object, which is often when digging stumps.
Thing is with the BX23, the hydraulic system runs out of power and the pressure relief kicks in way before the limits on any of the cylinders, lines and/or frame components are ever reached. If anything, this BX23 owner wished for more hydraulic power and a higher setting on the BH's pressure relief.....

If I ever expand my horizons and take on more land I can see a B3030 w/BH in my future so this is why I checked this thread out. I also would want the conditioned cab which means that at this time I would probably have to look at a Woods BH (unless Kubota changes to allow the BH to be mounted with a cab).
The title of the thread really isn't likely to draw many BX22/BX23/BX24 owner reply's as it applies to BH's of another class......

I've had a BH90 on my 3830 for the last three years. I've never had a problem with the backhoe itself and I've put it through some serious excavations.

The only problem I've had is with the subframe coming in contact with the lift arms of the 3pt hitch. That problem can be solved with careful attention to the lift arm positions when using implements. This was covered in other posts and doesn't strictly relate to the backhoe.

 

[bugstruck]

Roger the subframe/liftarm issue. Simple understanding cures that. My BH 90 has never really met a real test, so I'll pass on the durability issue for mine. Hasn't broke and surely shouldn't have. It's sure not commercial..day to day operation... grade. Was never intended to be IMO. Some have certainly had some cylinder problems though. I've posted in the past that most of them were when the defeats built into the controls were not working. You can't move the BH 90 in virtually all directions at once if the control defeats are working correctly and that saves it IMO. If it operates like a 580K for control input, it will probably break. It can't take cylinder on cylinder combined operating loads in every instance. Kubota engineers for that.

There are people who are happy with the Bota stuff. I'm not saying there are no defects either as I'm sure there is. If your not happy with bota hoes get a Woods then. I think they have a curved boom now, But i'm sure thats expensive.

Actually my dealer recommended the Woods BH when I recently purchased my B3030. The Woods was less expensive than the Kubota. He told me that the pricing to them allowed for better discounts on the Woods implements. Seems to be well built and a smooth operator.

This is why it is a good idea to measure your hyd pressure at the
hoe cylinders. Your hoe reliefs (main and per-circuit) could be set too
low (or high).

I was just taking some measurements off the new Kubota BT601 (on a
BX24 w/4-pt subframe---nice). As JD, Kubota, and Woods have all been
gradually moving to these curved boom backhoes, it is interesting to
note other changes. I wonder when there will be a 7.5-ft curved
boom Kub hoe? The BT601 has only one swing cylinder, off to the side.
I wonder if it can achieve a full 180-deg swing? Anyway the BT601 has
a 2.75OD dipper stick cylinder (same as Woods BH80-X) and a dipper
stick ratio of .22, which yields a dipper force of 2250 lb at 2000psi.

We own the BH 75 mounted to the B2630 and I think it is a good setup if used properly. Ours is in the shop on warranty work after about 2 hours of stick time. The valve control system under the control levers was leaking like a sieve. I thought I spilled some oil hooking it up but and wiped it clear. After another 20 minutes of run time it was dripping off the the mount plates. I traced it up to the control valving unit under right side curl lever. I fell like I have a pretty good hand at this so I know it was not overstressed. I am hoping that is the case because this would be a sorry unit otherwise. We will see how it all turns out but I can say it somewhat of a dissappointment on a new machine in that amount of time. I love the 2630 so far and it is well matched for my needs.
