Mine does not. There are pros and cons to this, as with other choices, but one of
the cons is surely how hard it is to install that shared pin.
I have the mechanical thumb on my BH90x. I don't find it useful but may upgrade to hydraulic.Quote:

It can trench. I would guess from my experience that it would cut a shallow trench almost as effectively as a bucket. It can trench/dig deeper too but would probably be slower as it cannot hold as much spoils as a bucket so emptying the trench would take longer. I would estimate that i can lift out about the equivalent of three human powered shovelfuls of dirt with each load.Quote:

Bottom line for me is that the ripper is optimized for ripping not moving dirt but it can certainly dig a shallow 1-2ft trench efficiently and is capable of digging deeper. The deeper you go the more likely a narrow bucket would be more efficient simply because of the spoils issue. It would be great at digging a very narrow trench about two inches wide by a foot or so deep as you would only insert the blade and spoils would just be pushed out ahead. Might work well for electric conduit or water line in a warm climate.
Thanks. Sounds like a 1' bucket is going to work better for what I need to do.... Water lines in a cold climate.
I'd only recommend the ripper if you have other actual ripping work to do however, otherwise a narrow bucket would be more efficient.
I had to resurrect this thread to give some thanks to IslandTractor for starting it in the first place. I had saved a link to it last summer when I had been doing some research for attachments I might want to add to my B3200/BH77. Yesterday - after spending about 3 hours digging away at a stump that just doesn't want to come out - I decided to bite the bullet and order a ripper from Michigan Iron. I've got 3 or 4 other stumps that need to come out - including one from a willow that got cut down last year that was about 3 foot around at the base - so I'm hoping this is going to help me get them out. The 18" bucket on the BH77 does ok - but it seems to large to really be effective at ripping roots out of the ground.
The Michigan Iron online order form said to expect arrival sometime around May 24th - I'm going to call them and see if there's any way to get sooner rather than later.
Great and very helpful thread!
After three seasons or so I am still very happy with my ripper. It does what it was designed to do. My only complaint is not about the ripper but rather the hassle factor in changing out the bucket/thumb. Last season I just didn't mount the thumb to make it easier to line things up. I've talked to MIE about having them build a quick attach mount but haven't gotten around to doing that yet. I am also in perpetual search mode for a taped pin that could be used to force the holes into alignment. If anyone finds a source please post!
