Hey Doug,
I found what you need. Go over to the Customization Forum and look at the thread labled Bucket hook Pics.
The second set of pics has a loader set up that i think would do what you want.

Yep... This is what I was referring to... perhaps incorrectly... as a compound bucket linkage arrangement:civesnedfield said:
If done correctly, this arrangement has the effect of increasing total range and rollback angle greatly... but note that it is achieved in large part by being able to greatly angle out the carrier. Note the angle formed between the line formed by the carrier pins and the front face of the carrier. Unfortunately, mine are essentially parallel to each other and perpendicular to the ground at DNB.
In other words, I don't think it would do much for me and my particular tool carrier without major surgery.
Also note that the front of that particular boom assembly is set at a much more relaxed angle than on my FEL.

Dougster said:Another view for JB. Note that the "tool carrier" is exactly vertical at dead nutz bottoming out on the FEL. In other words, whatever rollback angle I get at FEL DNB is provided by the design... i.e., the mount angle... of the bucket. Also note the angle of the bucket cylinder when fully retracted:
By my calculations, all I can gain is 13.7 degrees theoretically and about 11.0 degrees in a practical sense by kicking out the bottom mounting pin as far as possible before I reach a straight line between the upper and lower pins and the fully retracted bucket cylinder... which to me still defines the maximum achievable angle without getting into an unstable & uncontrollable situation.
Am I wrong about this? 11 to 13 degrees really buys me nothing in the marbles game.
Dougster, First point is based on your last comment. The 11-13 degrees you calculated is in addition to the current bucket roll back max. Assuming it's about 22 degrees, adding 11 bumps it up to 33 degrees. That's a bunch.
Can you please define what you mean by an "unstable & uncontrollable situation" ? That completely lost me. Maybe I'm not seeing what you are seeing ? After all there is a bit of distance...
Here's my modifications to your very nice picture.
By the way, what in the world did the police think they were arresting you for anyway? You can PM me if it's too embarassing!

Original spec is 20 degrees. I think I was overly generous with my 11 to 13 degrees gain... so let's say I gain 10 degrees for the sake of conversation. That's 30 degrees and yes... you are right... that puts me in the ball park of where a lot of folks are who have those compound linkage arrangements. Maybe my other problem is more at fault here... just a 15 inch deep bucket. Even at 30 degrees of rollback on my 78 inch bucket, that's only about 2.54 cubic feet of "water holding" capacity compared to 1.74 cubic feet at 20 degrees. Better, but still not very impressive.john_bud said:
Sure. I would not want an adapter that would ever allow the top pins on my tool carrier (and the rod ends of my bucket cylinders) to ever end up behind the line formed by the bottom pins (i.e., the pivot pins) and the top attachment points of my bucket cylinders. In a practical sense, I would never even want to come close to this condition. I do not need the bucket flopping back and forth... even a little... at the mercy of bucket load and boom angle.john_bud said:
It's not embarrassing, it's sick!john_bud said:
I have been in a dispute for some time now with my town on the road reconstruction being done in front of my house. I have always had a very steep driveway anyway... steepest in the whole neighborhood... and they have now placed an extreme crown in the newly rebuilt road... 100% of it affecting my side, 0% affecting the opposite side... and only in front of my house!!! The "Grand Canyon" is now at the bottom of my driveway. I could not get in or out with my cars, truck or trailers without bottoming out somewhere. The trailers are affected the worst and I have already made modifications to them and will need to do even more. I have also used the Red Beast to make critical adjustments to my driveway or nothing at all could get in or out of my driveway at this point... even my 2500HD pickup... without some scraping/damage.The town is sick of my complaining and very unhappy about the driveway mods I have made to date with the Red Beast. Two days ago, they came and marked for new asphalt curbing... placing it right in my necessarily widened driveway. Two days ago, I went out and "adjusted" their markings. They were not happy. Yesterday, they built the curbing right into my widened driveway anyway just to show me who is boss.
I went down merely to look at it (I knew full well that I could always remove it later with the Beast)... but also to fix farther down away from the driveway where a dog must have run through the soft asphalt and messed it all up... and the next thing I know, there is a cruiser behind me with one very nasty cop ready to arrest me on a complaint for "vandalizing town property"... to wit: fixing where the dog had damaged the curbing!!!
Turns out the idiot town inspector guy called the cops on me and told them I was "kicking the new curbing apart" and needed to be arrested. He knew otherwise, of course... this was pure payback. Shook me up good and took an awful long time to talk the cop out of arresting me. Ended up he didn't arrest me, but he still had to file a formal written report on the complaint. I am totally ticked at the town now. This is war!!! Dougster
I'm still having a tough time resolving the design that's in your mind vs. my understanding of your design!john_bud said:Here's my modifications to your very nice picture.
The distance between those two tool carrier pins (CL to CL) is 9-3/4". The bottom hole cannot be moved back 3 to 4 inches without tipping the tool carrier back too far. The most it could be moved back is maybe 1-3/4" to 2" tops before we get into the situation described above where the top pin of the tool carrier would end up at times behind the line formed by the pivot pin and the top of the bucket cylinder.Dougster

I've laid out the design as I see it. Make your model out of cardboard, then make one out of plywood. You should be able to mock up the plywood one and see if it is able to be a benefit in increasing the angle or not.
(that should keep you off the streets and out of trouble with "The Man")

About you current Alert Status Doug. I know that up here in Maine if a town modifies a road or drainage ditch and that modification causes the property owner damage. the town is liable for it. I know it may be a stretch but if you cannot get you vehicles out of your own driveway to get to work, or the vehicles are damaged getting out of the driveway, and these things are a direct result of the towns reworking of the road, you might have a case.
Just something to think about. I know what you are going thru, I have been fighting with my town for 10 years now about the condition of the road. It is a steep uphill battle.

That looks like my tractor!!!!!!!!!
