Larry, Wow! That's a piece of art. It's going to be an awsome looking landscape rake. You should file for a patent on this 8-)design

Larry,
Fun to watch, looks like you are really knocking this thing out. How do you end up having so much heavy duty steel material just laying around? Seems like you have a never ending supply?

Hi Tim, This is a fun project, my metal pile keeps growing with periodic scavenger hunts. When I see free, it quickly become part of the pile. I keep it hidden among the trees so as to preserve the natural beauty and my place does not look too much like a junk yard. Here are the operations taken to allow the king pin to fit through the boom. The pipe need to be cut, a grease fitting added then welded into place. That bring the construction phase up to date. I have been experimenting with some cylinder geometry in AutoCAD. I am toying with the idea of having the blade stay at right angles as the boom is offset to one side or the other. Here is the concept of how that is going to work ..... I have questions for those who have extensive real life experience with a rake. Do you use it at an angle? If so how effective is it? I would think with the tines at an angle it would act more like a blade than a rake. What about side forces on the tines when they are angled? My thinking is the tines are really designed to operate straight on rather than at an angle, is that true? Do you turn the rake tines backward, then back your tractor raking? How does that work? is it effective? is it worth it to push your rake backward with the tines digging in? Larry

Hi Larry, What a great project you are building, just as I thought it would be. Nice to see you doing all that machining too, instead of me for a change. You've got all the techniques down really good! It sure didn't take you long to learn how to use that AutoCad program either. I like the idea of keeping the rake square to the line of pull like that. When I turn Loretta's into hydraulic offset swing like that, it's going to stay square to the line of pull like you have your AutoCad drawing.
From my brief experience with Loretta's rake, I believe it works best when the tines are perpendicular to the line of pull or push. She can angle hers, but I don't think it's required unless you want the tines real close together and it becomes more of a rear blade that way. The tines are tougher than you think. We do turn it around 100% to push piles over the ravine edge by backing up in reverse, after she pulls it there. Then after several loads, we can push them the rest of the way out of sight. We have not turned it 100% around just to smooth yet, but I imagine it could smooth better and not pick up any debris that way. We haven't done that because we have the boxblade for that. Rob-

Super project Larry. I wonder if you could add a parallel link to keep the rake perpindicular while the hydraulics swing it side to side? Gotta go, Brad

Super project Larry. I wonder if you could add a parallel link to keep the rake perpindicular while the hydraulics swing it side to side? Gotta go, Brad Hey thanks Brad, That's a good idea, something like this?.... I updated the CAD layout to include the swivel / offset cylinder In three different colors and positions). The long yellow cylinder parallel to the boom will keep the tines at right angles to the direction of pull no matter the offset angle. That cylinder can also be used to angle the tines. Larry

After test fitting the bearings, they were taken off so I could add the swing offset cylinder mount to the boom...... 1/2" SHCS were used, the boom is 3/8" thick so they should hold okay. They were bolted on as opposed to welding so in the future as any part wears out, it can easily be replaced. Larry
