I noticed that the curl cylinder rod was bent! No leeks, and no idea how did this happen :( So i disconnected it and took it to a hydraulic shop repair for an estimate: $560!!!!!!!!!!!! Wtf, I almost fell from the chair!!! I turned the quote down of course, and I called me LS tractor guy. Brand...

Hello guys, I am building a pavilion and it happen to have White Ash in my firewood log pile so I was tempted to mill some Ash for the posts and the beams. I do not know if that was a mistake as I cannot find any data online. I took the risk anyway since I am using 6 8x8” posts on a 24’x16’...

The processor is done. A batch of raw videos are here This is the result after 1h 20mins. It would produce a lot more with full wider length logs. The operator has a skidder thats why he wanted the winch type instead of the live deck. The splitter looks slow because it has a 5in diameter...

Scook my apologies man, I did not noticed your questions before, I just saw them. a) The adjustment does not really take any loads. I will take some pictures tomorrow, but its nothing special. Here is one of the CAD, similar to the actual thing (its not the same because last moment the owner of...

Finally I have some progress and some real photos for you guys! This is the 2nd processor I design. My 1st one with the live deck is on hold. One engine for the saw motor / 6-way height adjustment / winch. 2 valves for the later, while the saw runs operates with a solenoid valve that gets oil...

It starts to take shape. I would like to review a few things (yes, the trunnion mount is one of them!! :) :) )though. My main concern is that I have no much experience with heavy equipment and I do not know what is the industry standards. Can you plz give your input on these things plz? a)...

Sorry guys, somehow my reply didnt get through. Texasranger, the cylinders have to go above the upper pivot, as Bfreaky's one. The reason is that the hydraulic tank is in the way. I understand it should go somewhere between the upper and lower, but really, there is no other place. I dont worry...

I am wondering if I could avoid the huge unique king pin. As I am designing that part of the backhoe, it looks like I could use 2 pins. One on top and one on bottom (between the green and the light blue parts). For the swing cylinders I couldn;t find affordable "trunnion" type mount cylinders...

If you put a little thought, philosophically, we are all coping someone else! Maybe we put 1% of invention, but the majority has reinvented before! :) So today I made some progress. Here are some pics. So far, the boom+stick+2 levers+bucket adaptor weights 350lbs. With a random 0.25 plate, for...

Do you mean this one? Its 4" horizontal distance now

Hello guys, I was thinking to make a backhoe for a while now and I was always postponing it, but I read Bfreaky's post last week and I decide to go ahead and do it. I will definitely need your help because there are so many stuff I do not know. For the history, I have my homemade 4'x8' CNC...

My own grapple in good use (my design& fabrication :) ). I didn't skid the log so to not get it muddy, its going on the bandsaw. This White Ash is going to become some nice tables :)

The winch type firewood processor finally got an update. :) My apologies for the mess!

You are exactly right!! But, the problem with these calculators is that they assume that the torque is constant as in a electric motor. With a gas or diesel engines thats not the case and one has to downsize the pump in order to actually handle the load. But another reason that I went deeper...

Its clearly on the engine specs.

I am reading from the manual: Maximum torque: 134Nm @1600rpm Engine Rated Power: 29.88kW@2600rpm (39.96Hp@2600) That simply does not make sense. Do they mis-advertise their product? The formula for power/torque is Hp = Nm x rpm / 9550, so torque= power * 9550/ rpm => 39.96Hp/2600rpm*9550=...

I give it a second thought. In this diagram on their data sheet, the clutch port does not really get pressurized in advance, as the oil follow the path of least resistance, which simply is towards the tank through the valve on the right. So If I do the following connection I do not see why It...

Do you have experience of on how easy it is to unwind a motor that is connected to a motor spool directional valve? (The ones that have the work ports connecte in neutral) That was my 1st approach before I saw that "clutch motor". Will it be realistic to pull a cable out of a spool for 30-40ft...

Hello, I am willing to buy this motor for a hydraulic winch. 22.8 cu in White Hydraulic Motor 5375A582AAAAE | Low Speed High Torque Hydraulic Motors | Hydraulic Motors | Hydraulics | www.surpluscenter.com I called their customer service, they have not idea how to connect it. I also found this...

Thanx man. Yeah its a lot stronger. The moment of inertia is 2x on the vertical axis and 3x on the horizontal! I just do not know if its overkill :( Anyway here is a peak of the ongoing CAD of the winch type design :)

Yes it is great improvement not only in hours but in hard labor. A friend of mine saw my processor and ordered one for himself, but it is a slightly different style, as we doesnot want to use another machinery to lift the logs on the deck, while he is skidding 30ft long logs from the forest...

I need to make a decision for my firewood processor and I have hard time doing so :( I have a 13.2gpm circuit (OC). (hopefully @1800psi with my 16hp gas engine and the 0.85in pump). But I assume I have a 12.5gpm system taking into consideration inefficiencies. (Should I lower that??) The...

Finally :) All the major parts are done, I figured out the hydraulics too. Full automation, for the clamp, and the saw feed cylinder. Its fabricating time! :) :)

Latest news guys is a sad realization that Sun's distributor in MA wants $1200 for this assembly (cost goes to $400 for 20pcs!). So that is a dead end, I do not think anyone can justify that much money. Here is the final design that I believe will work. Once again a lot of thanks to the guys who...

Sorry, its a little confusing! Here is the updated design, with the correct place for the Clamp retract (I think so at least!) 1) "OIL-FEED" is connected to the Directional Control Port A "OIL-RTRC" is connected to the Directional Control Valve port B "CLAMP-EXT" is pushing the Clamp...

This is the manifold design I came up with so far. I has a sequence valve (SCCA) that waits the clamp cylinder to build some pressure, then tees to 2 flow restricting cartridges a)12gpm to the saw motor (FDXA), and b) 1gpm to the feed cylinder (FCCB), and then I have a modulating cartridge that...

Oldnslo, what I deeply trying to do is to Open Source a manifold for a firewood processor, so whoever wants to build one later, to have it ready and do not have to go through all that hassle I did. Thats why my CAD design is also open. Now in particular, my main problem was on how to operate...

If I am correct with my calculations that flow with the 4.45in³ motor, gives me 3ft/sec and 5x load capacity than it will ever have to convey. I think its enough. If not I can always tune it up!! :) :) I want the minimum so I can feed the hungry saw motor! Btw I found some mistakes on the...

Hello, I am building a Firewood processor and the frame and mechanical staff are close to be done. I need a little help with the hydraulic circuit. In order to keep things simple for now, and to work with what I have in hand as much as possible, I removed the splitter circuit. It will run...

Following up on my old thread. The design is improved more, and its now on a different server. The fabrication has started, here are some pictures of what I have built so far. HUGE help is the CNC Plasma cutter that I built, I can precisely cut whatever I want ;)

Hello! Thats my tie rod after one quick wrong movement with my tractor in the forest. Can I just bent it? With or without heat? I was also wondering if it is wise to buff it up. Maybe put it through a wider pipe and weld it. If there is enough room of course, what may be the negatives of doing...

I do not have a BOL yet. But in general what I bought: $0 100 hours in CAD :) (winter hours nothing else to do :) $408 [1] 4x8 x 1/4" sheet of AR400 , I used almost all of it $190 on 24' of 3"x1/4" square tube but I used only 6' out of 24' (for the top tube $52 on 21' of 1"sch40...

Almost complete!! :) Thank you guys for your support!!!

Hello guys! I have been away for a while but I am back with some exciting news (for me at least! :)) Finally I started fabricating the grapple that I designed on my own. I spent 150-200hours on developing it. And with the help of some members I finally got it. The CAD file is Open Source for...

I need your expertise guys. I completed the major design, it is here, its open source to anyone to download, improve etc. I keep the story short, on the design link above I have wrotten my approach. Also here I have my diagram. Its ongoing now, and I need your help to make some decisions and...

Don't judge the cutting system is just a dummy right now!! I added it just for reference, and I added the chain links. I think it is ok. Maybe widen the clamp to hold at 6" and at 10" behind the saw. One valve controls the ram, one valve and a sequence valve control the clamp and the saw, and...

I am working on this project for a few months now, and I think its base structure is almost done. I am posting it here because I am wondering what major errors I may have before I start fabricating it. Even though I have figured out the hydraulic saw part, I removed it for the design for now so...

You are correct. I put the stress numbers on my first post though. Not able to confirm if was something wrong with the mesh creation, this is how it looks now. Be aware that I have not knowledge nor experience on using FEA. I just learn from google here and there. So if you think that I am...

HA! I got you! I have already done that! Its at the other side not visible from this view. Actually to say the truth and nothing but the truth, I cut the pocket mainly because of the need to adjust the 4way with hydraulics below the beam, and then realized that it helps A LOT. But I never...

I would never guessed, but look what a HUGE difference the Finite Element Analysis results to these models. I applied 35000Newtons to the cutting edges, with the cylinder base pin location as the constraint (the red round marks at the right of the pictures) The one at the left shows a...

I used to do it with the bucket, but was so much insufficient. What I did, was to buy a used plow blade (craiglist has them for $200 or less), buy this plate from amazon, weld a few pieces and voila! I have a regular plow. 5x times faster!

I am an owner of a XR3140 for the last 3 months, and I am new to tractors. Slowly I am finding that there are a lot of things that could improve the tractor experience, I would like to hear from you. Any ideas, tips are welcomed! I am not trying to list all the implements that exist out there...

So I sent this nesting to the supplier just to get an estimate (I forgot 2 pieces!). The cutting service is $300, and the charge for a whole sheet (4'6'' x 8'8'') of 3/8" steel is $388 for mild and $447 for A572 gr50. Small difference I think. $70 dollars for a lifetime tool is not much. I may...

I just installed the 3rd function kit. I haven't connect it to the plow cylinders yet, I am trying to see if I have to flush them clean first. they are old ones, I would not want to risk any contaminants to my tractor's hydraulic system. And I am pretty sure the guy who had them used...

I bought a used plow, bought the quick attach plate, cut the 2 mount points from the old mount, weld them on the plate and voila! 5x faster than using the bucket

I finished this grapple. And did some FEM analysis, and revealed that I need to tweak it a little bit. The only place that I am stuck and cannot analyse due to my software's limitation is the lid. Can anyone help me with his experience? What should be the thickness/size of a) the square...

I also agree that it is limited. Check out my design. I have to figure out a few details, and it will be ready. Grapple - AGreekulture Farmstead Wiki

So I finished the BOM you can see them here Whoever wants the 3dmodel can download it from here BUT..... the grapple will weight 448lbs without the cylinders. Isn't that tooooo heavy, that will restrict me from lifting 16ft green oak logs? max diameter around 16in. My tractor has lifting...

GLyford thats for you! :drink:

Yeahh!!! $200 for the plow. So now I have to make some mounts and the ssqa plate. How about the cylinders, can I flush them to clear any contamination? I dont want to risk any damage to the tractor.

My apologies guys, I have not updated the site with the Bill of Materials and the final CAD. I got caught up with a snow plow. But is very close to be ready. Glyford check this picture. Is not an actual deticated stop, but its some extra insurance. The plate that protects the cylinder and...

Similar. But, lets see if I can find a used one to adapt to the ssqa.

The grey part

Ok I hear you. No thrying to reinvent the wheel though, I had no idea about tha breather. I have already made the design to fit a 6" cylinder so to not extend too much in front of the tractor. Arrgg, I have to change it again??:cool:

I realized that the bucket is not at all an efficient way to clear the snow from a driveway, so the last few days I designed a snowplow for my LS that I will angle the blade with the 3rd function (I purchased the WR Long kit) I am trying to figure out 2 things a) Cushion protection. Of course...

Suggested changes are done, clamping force now is about 2070lbs

Hello to the community. Finally I finished the design of my grapple. I made quite a few changes from my previous post -if you remember it-. I change the approach because right now its not easy for me to handle a full 3/8" sheet, and I do not want to give the cutting to someone else because of...

haha! bo you didn't talk me out. I am trying to be realistic. As other people comment before I will not make any significant savings. While I really enjoy my designings on CAD and its almost ready for review. I am going to start another topic to get critisism, but here is a quick screencapture...

I am researching the forum for options 3rd function and while I found some very resourceful threads, I am still confused. My question is simple. What are my options for a 3rd function (not diverter or remotes) for a grapple that I am building for my tractor? I contacted my dealer and his LS kit...

Thank you all. Muddstoper, no intend to use anything out of specs man! Ok, I abandon the idea of 4". probably going to 5" I I understand the bending forces on the beam. I think that by keeping the cylinder as close to the beam as possible will limit that stress. But what about twisting? Is it a...

I am looking for a cylinder for my log splitting part of my firewood processor, and I see a huge variance in prices, and some differences in rod diameters. A few questions plz: a)If a cylinder is rated for 3000 or 3500psi will last longer when I operate it at 2500psi, that one that is rated...

Plans/BOM The last few weeks I am CADing the firewood processor I want to build. I have changed the design so many times, but I think its time to move forward. So far only the frame, and the loading and infeed conveyors are kind of done. The link above is a work in process. The BOM is not...

You are absolutely right. The way I approach each project, is to make the CAD file first before do or buy anything. In this case it happpend to have the gas engine.This is were I am right now, at the very begggining. Make the CAD. Spend a few days/weeks just look at it again and again, ask...

I am starting to play with a firewood processor design. After researching the forums , the net, and 9kproducts website, I saw processors with big gas engines, also some with 2 gas engines one for the splitter with a 2 stage pump, and one gas engine with a regular gear pump for the rest of the...

Hello all. I am new to hydraulics, can you recommend any good resources that I can study? Online, books, anything. I look at all the different devices at surplus and I am getting dizzy! How to design a system, what to consider, math calculations etc. I want to start 3 more projects (the first...

Got you. I am wondering if it makes the lid more stiff, and if that worths the extra weight. Anyway, I just used the simple approach with bolts/ nuts instead of a tube with a greasable pin. If that fails soon or needs too much greasing I will upgrade it with the enclosed pin. I think the...

You are right. I will do the simple approach then, with one pin/bolt for each side instead of one big one. Maybe The lid sides are 18" apart.

Now that I have a better understanding of the geometry etc, I had to deside at a few things. Go smaller to fit the 4" cylinder better, or going bigger and but a 6" cylinder. I tried bigger. By 3" in length and about 2" in height. This is what I have now. (Some components are missing and others...

1957lbs , made it class 2 lever, so end up 2100lbs on the teeth! Wtf that stuff are so fun! And since you say the 2" cylinder is too quick, replace it with a 2.5" and we have 3280lbs...:cool2: Thats the proof!

I agree with everything but I think you have an error on the the last picture. But yes, summarizing, I use this simplified formula. Fin = sin(A) * F * L1/ (L1 +L2) Fin= the final force A= the angle F=the Cylinder force L1- the distance between the pivot and the end of the cylinder L2 the...

Thank you guys. Your comments directed me to what to research. Feel free to correct me if I am wrong, no offense taken on construtive critisim. So, you end up with 7500lb of force by using the formula for the force acting on the opposite side of the rod F2 = (π* d^2 / 4)* P2 ==>...

Question #2 :) Take a look at these 2 different designs. It shows the tines both opened and closed. The white measurement is the opening to grab material. The white circles with the red measurement is the cylinder in the fully retracted and full extended position. At the 1st image I used this...

You may be right, but I would like to see the actual cost in the Bill of Materials. No offense, but your sense and experience (and a lot of people aggree with you as I see in the comments) is that I am not going to save -which is subjective-, my sence (and inexperience :) ) is that I am going...

Hello everyone, newbie to tractors. I just got a LS3140, and I have 65ac of forest that are waiting for me! I am Open Source enthusiast, and I design in Freecad Nice meeting you all

Hello to the community. I just bought a tractor last week, and I am so excited! I quick realized the need for a grapple. I have 60ac of forest that need heavy thinning and I also need it for loading the firewood. My apologies to my ignorance, my experience with tractors is only 1 week. Thats the...
