3 point alteration

[Gramps in NM]

2005 4wd Taskmaster (dongfeng) with loader and rear blade. 2 hyd. pumps, one main one for steering.
Morning all. This is for a starting point on a 3 point discussion. I have lots of distance to cover while using a 5' rear blade on GRAVEL/DIRT roads/drive. I use it also for snow removal. Yes there is snow in NM. Had 17" here to date this winter.
Problem- 3 points do not raise and lower with any degree of accuracy, another words it's difficult to keep from going to deep (I also have steep slopes) or to unload a small amount of material over a given distance. Try to raise the blade just a little and it goes up to far. It seems no matter how the thing is adjusted it does not provide the adjustments that would come with say a hydraulic piston.

Solution-Need More by the way- My idea for you smart hydraulic folks. What if the top link were replaced with a hydraulic cylinder. I realize the top link is mainly a pitch adjustment for the blade and to provide stability but it also does provide a small amount of adjustment in the up/down plane. 1-1 1/2 inches, perhaps more. This would be enough to fine tune the height of the blade to keep from digging in to deep on soft material and also allow for a small amount of material to be dropped from the blade while moving along over a distance. It of course would need to have a source of pressure and the needed lines, valves and so on. I have no idea on how to hook up such a thing so need help in that area for sure. How about it, is it feasible? Would it provide needed control? How could you hook up such a gizzmo.
Ideas anyone?

Check out this epic thread by Rob where he (among other things) adds hydraulic top and side links to his wife's Jinma 284. He does amazing work and details just about everything he used in the project.

I added a hydraulic toplink a few years ago. Probably the single best addition I have done. Fantastic for any 3pt manipulations. The versatility it gives you is great. I have it hooked to one set of remotes that i can control easily. The video shows what you are talking about. You only have to watch if you extend it to far it bites into the ground which is great for certain things but not necessarily for snow removal.

A HTL is an invaluable tool, but would be minimally helpful in resolving your scraper blade issue. Before spending the money - or possibly entering into some possibly irreversible mod - you might want to start by cleaning the valve that's associated with the lift lever. You should have more control over those arms than you describe. Another thing is to determine whether or not your DF has draft control. If yes, its sole purpose is to keep ground engagement implements from digging too deep.

That crane setup is really slick. What kind of lift capacity does it have, and is that a second cylinder attachment point on the boom for more lift at a restricted range?

Have looked at both the links given and all the pics and video, WOW, what fantastic ideas and work. Really impressive.
My manual does not mention draft control but based on my experience with my old 8N and another unit I believe it's there. I have limit stops for both up and down on the 3PT lever control also. It does work smooth and the control is ok, just not what I would like when considering soft ground/gravel. That's what prompted my query. I would like more finite control considering the terrain I work in. Attached are shots of the upper level of my driveway.
I'm going to look into this more but believe my answer lies in adding a cylinder and control. From what those who have done it say, it's the cats MEOW.

Not sure the capacity. It will vary of course on how far out your going to lift something and how much front ballast you put on to balance. If your lifting with the feet from the 3pt on the ground you will have more capacity but can't move around with a heavy load. It has been handy to move things into tight spaces. The boom extends out another 3-4'. That front lifting point is just to lift from. I don't think the cylinder can attach there although I may look a little closer at that. I have a 3pt adapter for my FEL that I want to put this on and give even greater reach. not something you use all the time but for lifting trusses or things that need precise lifting, very handy.

That's a beautiful drive you have. It looks as smooth as my concrete drive, nice work! :thumbsup:

Well, I have to say that about your drive. It's beautiful! I'm hoping you didn't hand place all of that stone work that lines the drive. :confused2:

Unfortunately we did just that with the stones, placed by hand after hauling in a trailer behind the ATV. There is several hundred feet not shown also, all from our "mountain". No fancy mortared walls here, left it as natural as possible. Glad you like it, just need to rework the place now after the last snow removal, but expect 6-8 inches tonight.
