Kubota B2620 & MX5100
I am going to add the Back Hoe to my MX5100 next month. My dealer usually orders them with an 18" bucket. I am thinking about also getting a 12" bucket. I have alot of drainage lines to put in and I would think the smaller bucket would be better for digging stumps. It seems the smaller bucket would be better for tearing out the roots. I think the 12" bucket runs around $600.
What do you guys think?

Yep, you are correct on all accounts. If you can spring for the extra $600 the narrow bucket will likely be your "go to" bucket for trenches and tree roots.

The 18" will move a lot more dirt when you need to do that.

Dixon,
Thanks, I guessed right. I've had hoes on my other Kubota's so I have a little experience. It just seemed like common sense to me,

Yep, added a 12" bucket to my arsenal this summer. Trenches and stumps. Does it have a quick change bucket setup?

I have earth with a high clay content and gave up on a 12" bucket pretty quickly. Take one scoop, spend half an hour getting the clay out of the bucket.

Not a problem with 16-18" buckets.

Plus, a hydraulic thumb will not work with a 12" bucket on my machine...

Now if ever see a good deal on a 24" bucket, I will take that in a heartbeat.

The hoe I'm getting isn't quick change, but I don't think changing buckets will take that long. I know what you mean about clay though and I think mud is similiar.

Thanks for the topic. I'm still in the pre-purchase planning stages, (likely a 3940L), and plan to get the backhoe, probably with thumb.

CurlyDave (& others), could you explain more about why the hydraulic thumb won't work with your 12" bucket? Is the thumb too wide? Thanks.

as Curly Dave eluded too, I think I'd go with a 24" bucket if I was adding a second 12" bucket.

I had a 12" bucket and could not wait to get rid of it. Spent more time digging clay out of it than using it. I have an 18" and 24" now.

I use a frost ripper for roots and such. You could make one out of an old subsoiler shank.

The thumb itself is not too wide, the thumb mount is too wide.

I have a QA backhoe bucket, and the QA assembly is pinned onto the dipperstick. The hydraulic thumb is mounted on a common pin with the QA assembly. (This allows changing the bucket, while the thumb stays attached.)

Part of the thumb install kit is a longer pin, which has room for the thumb mount. The pin is longer than 12", about 14" (from memory). If used with a 12" bucket, the ends of the pin would scrape the sides of a trench.

I don't know if Kubota thumbs are the same, but I suspect they are.

Given that the 12" bucket packs with clay and is a general PITA, I happily sent mine to Jenkinsph in exchange for fabrication he did for me to mount a hydraulic auger on my backhoe.

I have either a 16" or 18" bucket now, and it works very well.

As I see it, the only real disadvantage of the bigger bucket is that if I want to sand or gravel bed a pipe in a trench, I will need to buy more sand or gravel. To me, this is not a big deal.

Smaller hoes may need smaller buckets just because of digging force issues, but I have enough power and have never wished for the 12" bucket.
