Ready for paint and hydraulics. My LA loader has the Kubota quick attach system and this is designed to work with that.

Sorry for the terrible picture quality, will get some better photos later this week. I couldn't resist the temptation to have the logo water jet cut into the front plate. It wasn't very expensive - hope Kubota doesn't mind. Attached Thumbnails. Reply With Quote. Love the logo. Is that a 2" cylinder, hard to tell in photos??

You may want to consider some trussing on the claw. When it'll bend is when one side of the claw is gripping a larger item than the other side. All that twist is concentrated in the claw design and adds stress in wierd places.

Easier to fix now than have to straighten and reinforce after it's bent.

THE CLAWWWWWW!!!! (Unboxing 36\

Keep in mind the grapple's power to clamp is determined by the tractor's hydraulic capacity, not by the tractor's size or lift capacity. So in practical use your tractor can clamp just as tight as my M, just maybe not as quickly. Another issue is that you need something to protect the cylinder.

For example, if you clamped onto a stump that would fit in the "V" shaped hole under the cylinder you have a high chance of bending the cylinder. Again, great job, looks great!!! Richard "Happiness isn't having everything you want, it's wanting everything you have.

Had not thought about the cylinders expose from underneath; I will consider that before painting. Thanks for the compliment. Re: Another DIY Grapple Got some better pictures this morning: Looking for a local source for sandblasting before I paint, hope that will lead to longer paint life.

I am looking for a good set of plans to build a dangle log grapple, good for about lbs, roate, 3inch grip. Anyone there to help is appreciated. Not sure if we could find that as Farma is a sponsor? Gee, it's not like they could look at a picture of a Farma Grapple and build there own. Farma makes good looking stuff for sure.

Somehow I think they're secure enough not to worry about a guy building their own. The reality is that most people would spend the cost of a finished grapple just to build their own, and it wouldn't work as well. There are a few people who could do it for cheap, but they would have to have decent equipment. Bobcats and forklifts. I'm very happy with the Farma grapple I have. I would not be able to build one for what I paid for mine. Perhaps you have the equipment and fab skills that I don't.

Stuart Clark is quite the builder, compared to most, so his input is probably the best so far. I haven't had the full compliment of coffee so I edited a post. Do you mean a grapple that would attach to a skidsteer, the rear of a farm tractor?

Thanks, I can build just about anything I need, but I learned a long time ago that it's hard to beat a man or company at their own game. I'm pretty sure I could build a Farma grapple, but If I needed one, given what they cost, I'd just buy it. My time is better spent earning money in my CNC shop. When I built my LX extension I chose to buy components from Woodmizer because they were simply cheaper than I could possibly build them myself for.

I only built the extension because it wasn't available otherwise. In retrospect, I wish I'd just bought the bed rails for example. Some folks have more time than money. There's a guy here that sells a log loading trailer with grapple plans Buildit plans home Years ago when I was building thumbs, rippers, brush blades, etc. I'd often swing by a dealers yard and look at the newer innovations.

Often I would take a yardstick along and set it next to something like a thumb on an excavator. It's a simple process to bring that photo into a program like Corel and trace the outline of the tool you want so that you now have a vector based scaleable drawing. Trace the yardstick as well.

Export the trace to a cad program. IN the CAD program adjust the scale so your yardstick actually measures a yard long. Everything else is now to scale and you can draw whatever you need. Shift your drawings to use the materials you have and you're ready to start cutting materials Even if i never build a loader that set of plans provides a visual on how things go together.I am starting on an addition to my trailer.

Here is the design I came up with. I designed this with a 3D software package from Alibre Inc. Here is the trailer before I started.

I have some of the steel for the project on the bed of the trailer, and in the picture to the right the pins and bushings that are going to be needed. I have reattached all the log bunks to the frame, and in the front you can see the start of the log loader base.

I am mocking up the outriggers. I have cut out the plates that will reinforce the pivots and am doing a test fit. I have the outriggers all tacked together.

All that is left is some final welding, and run the hydraulic lines. My brother is doing most of the welding on this project.

I can weld, but he does a much better job then me. So I figured it wouldn't hurt to let him do the final welding. Here he is welding the pivot plates on the boom and stick. I am test fitting the boom to stick pivot. We are using a magnetic drill to drill the holes for the bushings.

I have the boom to stick pivot together. Here I am test fitting the swivel that the entire boom assembly will attach to. We are welding the swivel together. Welding on the gear that a hydraulic motor will power to swivel the boom.

Here is the base assembly welded to the trailer with all it's braces.

Here is the shaft for the bearings for the swivel. And I have installed the shaft into the base. We installed the bearings and placed the swivel on the shaft.

We lifted the boom up to the swivel with the cherry picker. Then we welded the bushings for the pivot pin in place. I then lifted the stick into place and installed it. Here is the stick pivot all assembled. We then made a mount for the engine. I am starting on the grapple.

On the left is one set of tines for the grapple. And on the right is the base of the grapple and the other set of tines installed. The grapple is all assembled.No winches, no hydraulics, no electricity required.

Simply back up to the log, block the tires, release the latch pin, back up further to slide tongue and lower lifting lever.

Hook up log tongs or chain. Move to block to the front of tires and pull forward to slide tongue forward and raise log lifting lever. The tongue has a self-latching pin to lock it in place. Remove blocking and move the log to the desired location. Less horsepower is required to pull the log. Your email address will not be published.

Google Analytics.We live on a fifty acre lot with lots of bush for firewood. I have been retired for twenty years and like designing and making projects in steel, mostly. I constructed a forklift and log splitter for the same John Deere tractor. With this equipment and a winch for the forklift, I have eliminated the need for any and all lifting while cutting and splitting fire wood.

Cutting firewood is a big enough job as is, especially when you add the lifting and stacking. We've showcased a few cutting and splitting machines before, but this unique tractor-powered attachment Hank designed takes firewood processing to a whole new level. The first time he used it, he managed to cut seven cords of wood. See it in action here. If you have a specific question about this project that isn't answered below, submit your own question to the project poster.

A: It's a grapple with four logging tongs, used to pick up a log and lift it to a standing working level for cutting into four stove length blocks, and for stacking the blocks away from the log pile. It eliminates the danger of chainsaw kickback, cutting logs on the ground, and manually lifting heavy blocks of firewood to move them away from the pile of logs. Q: What is the main power source for your project? Q: What components are used to perform the work for your project?

A: Hydraulic pistons and a large rack-and-pinion for rotating the boom on which the grapple is mounted. One piston opens and closes the four tongs of the grapple.

These tongs are spring loaded: when the first tongs grasp the largest diameter part of the log, the remaining ones can keep closing till the smallest diameter of the log is contacted.

All tongs can close to diameter of zero inches. If a log is 18 inches at one end and 10 inches at the other, both tongs will bite into the log, so that when the blocks are cut no blocks will drop.

If the tongs were connected all with the same rigid openings, only the largest diameter of the log would be grasped by one of the tongs. Q: There's a small platform with wheels behind the tractor. Can you tell us about that? A: The small platform with wheels is a platform I had from a previous project that went obsolete when I came up with the grapple idea.

The wheels are used to maneuver the grapple for hooking up to the three point hitch of the tractor, and parking it in the barn where there is not enough to room to move it around with the tractor. It actually has three wheels. The one is a caster on a jack so the unit can be rolled around by one person. This is actually a trailer jack from Princess Auto.

It was added after the photo in question, so it is now a tricycle unit. A: Mounting the rack and pinion to swing the boom almost degrees. Getting a small diameter hydraulic piston to pull the grapple tongs to close them. Holding blocks of different diameters by using springs to allow the four logging tongs to hold all the blocks once they were cut.

Q: If you had to build it again, what would you do differently? A: If I were to begin from scratch, I probably would not have used the rack and pinion unit. I also would have used a four spool control valve instead of power beyond valves. I would also have made the unit that holds the boom smaller.

However, I had these all as things collected or donated on hand. The rack and pinion unit allows for more rotation than a piston on an arm to rotate the boom. Plans are to install outriggers for stability.

Simply remove the pivot shaft, place the grapple at desired height and slide pivot shaft into position.Harvesting firewood starts with the task of downing tree's, and retrieving them from the woods. This is no easy task without the right tools. These Log Skidder Plans will help you build your own log skidder that you can use to move trees and large logs out into a better working environment. As the picture below shows, this simple design for a log skidder allows the securing chain to slide up a riser rail bar and lift the leading end of the log off the ground as you pull it to your destination.

This keeps the front edge of the log from digging into the ground which will make it much harder to pull. These can be found searching online in locations like ebay and amazon. The kits should include several parts that are needed other than the fabrication steel for the frame.

These components include:. As the pictures below show, this log skidder frame system is constructed of 2" box steel and requires very little ingenuity. This simple structure includes the arch that the log will be secured inside of, and the riser rod the log chain will ride up on to lift the log off the ground. The rest of the frame includes the front triangle, tongue bar, and wheel guards. A relatively easy fabrication process. Another design for the log skidder frame allows the use of a come along ratchet cable winch to be used in the log securing system.

With this setup, the winch is cranked up to lift the front end of the log up off the ground. Safety can be a big issue with this design and injury could occur if the cable were to break. A third design for log skidder plans use a grapple to secure the log for transport. This system can even include hydraulic or mechanical support for lifting the leading edge of the log off the ground as seen in the picture below.

Other options include a 3-point hookup that can be employed. The difference between a log arch and a log skidder is that the arch is intended to carry the log, where the skidder is intended to drag the log. In the right situation, the log skidder is going to help you be more productive since it takes less time to hook up to the log for dragging. On the other hand, a log arch will keep your logs cleaner which will extend the life of chainsaw chains and sawmill blades. Either way, adding this contraption to a scrap yard log splitter will get you all set up for firewood production.
