QA Bucket Rollback Angle Increaser???

[mboulais]

Dougster,

1. Your bucket is skidsteer style qd, right? The adapter/spacer would need to have both a skidsteer plate on the back to attach to the loader and a simplified skidsteer tool carrier on the front to pick up the bucket. The tool could be at say 5 or 10 degrees angle to each other and yield the geometry changes your looking for. Your bucket would end up 4- 6 inches further out in front of you.

2. If memory serves, and it probably doesn't, there is another set of cylinder mounting holes on the loader. If the bucket doesn't come back to positive stops, a change in geometry might be accomplished that way also.

That's exactly the idea! Precisely what I am looking for! Do you have one?

I'm afraid that won't help. The two holes are exactly in line with the bottom hole. Either top hole and I've got exactly the same rollback angle. If anything, that lower set of holes would give me more bucket "speed"... but less resulting torque. Doesn't seem to be useful... at least not to me anyway.

BTW, the manual says nothing about that second (lower) set of top holes other than pointing out that you should only use the upper set. I'm guessing that lower set is there for use on a different machine.

Dougster - I'm not sure how your Mahindra bucket mounts, but on my JD QuickAttach bucket, the bucket rests in cradles on the top and has alignment pins on the bottom.

If I were looking for a way to slightly move the bottom of the bucket "out" (forward to give more curl), I would try to fab up some custom pins that are sleeves on one end and solid pins on the other. Then slip the adapter pins over the existing pins on the bucket w/lynch pins and they would then add 2-3" to the locating pin setup. Maybe alignment and weight bearing issues would apply though most of my bucket weight is loading on the upper attachment cradles. Does this make sense?

It makes sense... but I am not sure the bucket would hold in place for very long under actual working conditions unless there was a pretty stiff and beefy "frame" on each side to hold such a mechanism/adapter as you describe in place. The other issue... as mentioned above... is the ability of the "cradle" as you call it to remain tight and functional as the main vertical load support and not slip out an at angle other than flat and fully inserted.

I think this is yet another case where the concept is fairly simple... but the *you know what* of it is all in the details!

No, I don't have one. The attachment plates can be had from preseeder.com at a reasonable cost, then somthing needs to be custom built on the back of it. Instead of fancy springloaded mechanisms to lock the bucket to it, I am thinking 1" dia. draw pins might work. I think someone posted ther dimensions for the skidsteer mounts on here recently. A second bucket with one of the heavy duty skidsteer plates welded to it with a 3" tube steel spacer under would be alright, but would mean transporting a second bucket to each job, or sacraficing 5-10 degrees of dump angle. You could still back drag even loosing 10 degrees of dump.

OK... a little late coming to the party, but I did make it. I can't really help you much here. There have been some good suggestions already. One thing you have to remember is that what ever you do... you may reduce your dump angle.

I think you are on the right track. Buy a blank QA attachment plate... add a top ridge to it... and then add a lower hinged QA pin mechanism that could lock firmly into place with bolts or short pins on each side. It would take me longer to draw it up than for my local steel fab shop to make it!

Welcome Jeremy! Still kinda early out there in Kansas... yes?

Understood on the dump angle. I think this "adapter" would be for limited use only in unusual situations as I would NOT like gravel or anything else raining down regularly on my hood! I really like the way your buckets are designed to prevent that. But picking up all this loose, spread out pebble gravel is an endless task just going at it straight on... kinda like trying to pickup water.

I too am joing the party late. Whatever you do, let us know and show pix. I have a similar problem with the JD 400CX FEL. While the initial roll back is the same as the 400C the self leveling keeps it at that angle, I can't get it back enough to drop things on the hood. So carrying stuff a long way equals spreading. I don't worry about the dump, as the angle at full dump is 90.
One item I was thinking about is using a fairly thick (1/2-3/4) steel plate to hold the extension pins in place. Hollow pin one one side, solid pin on the other extending through the plate. With reasonable machining and welding the thickness of the plate should prevent twisting, and spanning between the sides should prevent shearing. I'm guessing the hollow section will have to be at least 1/2" wall, or braced back to the mounting plate in two axis.

It is on my winter to-do list, so hopefully some one will come up with a better fix before then.

Ha!!! I like that! But I'm not sure that using what I am envisioning will help YOU as much as it would help ME!

Also not sure I am visualizing your particular idea exactly, but we're all in the same ballpark here. One way or another, kick out those bottom feet just enough by adding a dummy pin hole and a real pin on each side. I still think the trick of it is all in the side supports that I feel would be necessary if this adapter was being built and intended for heavy-duty use.
