    Default Backhoe bucket mount

    OK, I mentioned before that I'm thinking about buying an 8" trencher bucket and building a mount to hook it to the front of the PT1418. Given that I can dig reasonably well with the 48" toothless bucket, then I should be able to dig quite well with that small of a bucket (just shallow, of course, but that's fine for my needs).

    So, I'm looking at probably ordering one of the 8" skid steer backhoe buckets from NorthernTool ($175 seems like a really good price). I'm assuming it has 4 eyes welded on as the attachment points. I'll then have to make a "frame" to mount it to, then mount the frame to the PT. I'm thinking 3" wide 3/16" thick steel angle stock for the frame. I'll use 3 pairs of heavy-duty u-bolts for eyes to mount the frame to the PT's 3 pin holes (2 lift arms and 1 curl arm). I'll probably bolt the bucket to the frame. I have a small 90 amp wire feed welder, but I'm not sure it'll make enough heat to weld the thicker metal together (although it might), so I'm looking at using mostly bolts to hold everything together.

    On my 48" bucket, the 3rd eye (the one the curl arm attaches to) is only about 6" above the 2 eyes that the bucket tilts around. I'll have to measure it, but I'm thinking I'll increase that distance with the trencher bucket to around 9-12" (the largest number that'll still curl enough to move the bucket), that way it'll get considerably more leverage. I'm thinking here that the process of shoving the bucket into the ground will come from angling it down, lifting the front end of the tractor with the bucket edge, and possibly driving the machine forward (the same way I dig with the 48" bucket on). Pulling out a bucket of dirt (and rocks and roots, etc.) will mainly consist of curling the bucket up, then raising the lift arms. I could possibly also drill all the necessary holes so that I could mount the bucket on the frame so that it faces down instead of up, but I'm not sure that'll be as effective without an additional arm and cylinder.

    Anyway, I'm obviously still formulating how to do this and how it'll work most effectively. Do you think 3/16" thick steel angle and large bolts will be rugged enough to handle the forces I'll be putting on it? Any other suggestions? (I have to keep this reasonably simple. I have a pretty good imagination, but I'm still a newbie at fabrication...) If you have any suggestions, please post 'em!

    Regards,
    Dave

    Actually, another thought here. The stump grinder I have is bolted to a plate that already has the 3 pairs of eyes for the 3-pin connection. I suppose I could validate my assumptions by removing the stump grinder from the plate, and drilling holes in the bucket and bolting it on instead. That way, I could certainly check that this'll work as well as I'm thinking it will before I buy materials and waste time making a mount/adapter, eh?

    Sounds good. I wonder if 3/16 will be thick enough. Just measure what the current setup has and duplicate it. That should be thick enough, I would think.

    I'd love to make something as thick as the plate the stump grinder is mounted to, but that's something like 1/2" - 3/4" (it's a THICK plate!), and I don't have anyway to cut or weld something that thick. (Of course, I could get a shop to do it, but then I might as well buy the plate with welded eyes from Power-trac). One additional thought, however, would be to move the thick plate to the backhoe bucket, then make a lighter duty mount for the stump grinder....hmmm...let me think about this one...

    I finally got around to ordering this 8" bucket from NorthernTool. After I get something made up to attach it, I'll post some pics...I probably won't get the bucket for two weeks or so, and given how slow I am, it'll probably take me a month to make a mount, but we'll see...[img]/w3tcompact/icons/wink.gif[/img]
