Attachment for my tractor

admin

When I got my tractor one of the things that I wanted to get/make was a grapple.I have been taking evening classes learning how to weld.  The instructors are great and the facilities are fantastic.The grapple is made from 5/16's T-1. I designed all the pieces and had a local company plasma cut them from .dxf files I e-mail them.Anyway, got it all plumbed and got to try it out on the property today.  It works well. I need to paint it next.  Skeptic  Attached Images
Reply:how much did all that cutting cost you
Reply:Nice job! Now you are ready for some serious work
Reply:Nice job,Can you show us a picture of it in action?   Can we see how you connected the loader to the attachment and the hydraulic connection.   I have the 4300 with the 430 loader and it's my favorite tool to use everyday.  I have been working on a frame for a set of forks.   I'll send pictures soon.
Reply:The cutting was about 12-15¢ per inch (I had two jobs that I needed cut, hinges were cut later).  I winced at that at the beginning, but when I saw how well they cleaned it up and stuff, I was fine with it.  The material was all weldable from them, they had done all the grinding for me.  So cutting all of that was about $200.Works pretty well, now I can pick up all the branches that came down in the storms! We have stacks of them all over. Attached Images
Reply:damm that thing is SICK, well worth the 200 bucks to have it all cut out and grinded, how much can you lift  with that? good luck, and nice job brian
Reply:nice. next project is the counterweight for the back end and replaceable teeth.:-)
Reply:This is the frame for my forks. everything is 3.5 inch X 3/8 angleon top,  1/4 inch toob and I beam.   I still have to make the forks out of channel iron.  Sorry about the dust an the flash. Attached Images
Reply:Here is another picture  from the front Attached Images
Reply:Nice job Skeptic. That is one mean looking attachment What is the width of the grapple. I hope you park that thing against a wall. Would hate to walk into that in the dark.Sticky, your project is nice too. I bolted channel forks onto the bottom of the bucket on my 541 loader. Watch out for that dogs tail.
Reply:Geez, that thing looks like something from Monster Garage!  If it was on the front of a Honda Civic I'd be sure of it!Seriously though, super nice job.  I've built some tractor implements but nothing that elaborate.  Did you do the hydraulics yourself?Nice pair of Labs you got there!
Reply:Here is a picture of the grapple picking up a rusted out 55 gallon drum.It works pretty well.  I should be able to lift to the capacity of the tractor, I calculate about 700lbs will be around the limit. Attached Images
Reply:Here is a picture of the back of the grapple.  We made the hooks for the quick attach part by heating and bending the 1/4" plate.  I didn't know how to do the hydraulics myself, so I had them do that for me at the dealer. I was mostly concerned of how I was supposed to take the one connection into the two cyliners.The width of the grapple is 52" (that matches up with the front end loader on the John Deere), the top is narrower so that it fits between the loader arms when fully open.  Shari Attached Images
Reply:For 50$  certainly would have been glad to mention you would have to T the cyls. Ha  Are you running the grappel from the remote hyd or did you add another valve?www.urkafarms.com
Reply:Well, I will know better in the future.  on putting hydraulics together.  I had another valve installed earlier in the year.  The control is located on the right side of the seat. Of course, now that I have it working I am thinking of ways to be able to control the grapple closing (or opening) while I am lifting and tilting the FEL controls.... not very easy if I want to keep my hand on the steering wheel.I am running out of branch piles to pick up  My next project is a fork lift attachment for the FEL.  I have some ideas on how to make it customized.  I have been keeping an eye out for auctions to find some used forks.  Shari
Reply:Skeptid,Most of the time used forks are bent.  The 430 loader can only pick up 1300 lbs. so the more weight you put on the noise of the lift, the less you can lift, like heavy forks rated to lift 5000 lbs.I am going to use 5 inch channel iron and box in the back.  I don,t think it will cost more than $50 and everything will be the lenth I want.
Reply:Sticky, You are correct on the weight.  I need to be a bit more realistic about the weight I want to put on the front end and still be able to lift things.  Are you going to make your forks adjustable?    Skeptic
Reply:Don't worry one bit about running out of brush to pick up, just head East on I 90, I'll be more than happy to provide brush piles.Is that tractor set up with open or closed center hydraulics?  Does the loader have a joystick or 2 spool valves?Appreciation Gains You Recognition-
Reply:Skeptic,I f you look at the picture of the frame I made for forks and bail spear, you will see 3/8 angle on top for the forks to slide on.  I think most pallets are 42 inches long so  I will probably make them out of 49 inch long channel on the bottom so it under laps the tube on the bottom of my frame (that  bottom fork 90 will be a T) . I'm not an engineer, but I think the bottom fork extended a couple of inches will take some load of of my 90 angle.  They will slide on and off on the ends and be a little more stableInstead of making a round handle for the loader to connect to the attachment, I used my extra 3/8 inch angle iron. I took two 90 degree triangles and welded them on top for overkill support.    It is a square U instead of a rounded U but it is 3/8 and very easy to measure and make.
Reply:Franz,Sorry it took me so long to get back to you.  I have been running a retriever field trial this weekend.  At least we had good weather for February.  Shirtsleeve weather and calm winds.The tractor has open center hydraulics. And the FEL is controlled with a joystick.  Of course, it would now be nice to have a button to open and close the grapple actually on the joystick.   However, I believe that is a BIT pricey.  I have neighbors that are interested in some of their branch piles being moved too   Shari
Reply:You really don't want a solonoid valve operating the grapple, unless you like the sound of clanging metal and smashing things.Locate the line running from the valve body back to the reservoir, and insert a single spool open center valve there for the grapple.The clown engineer who invented joysticks should have been whipped.Appreciation Gains You Recognition-
Reply:Franz-I love joystick on loaders and trackhoes, especially on the latter.  I guess skeptic has his grapple plumbed in inplace of the bucket roll.  Another way is to add a solinioid valve past the joystick, with the switch on the joystick, that switches flow from the bucket roll to the grapple close.  This is commonly done with 4 in 1  buckets.  You still get a proportional control from the joystick.Skeptic- Any chances you could post the or email the .dfx  files?
Reply:I have pdf files mostly finished and I have many of the dxf files ready. I have just been doing a bunch of fixing computer networks in some old buildings, kind of keeping me from fun stuff.I had a new valve added.  So I still have the up/down, and roll of the FEL, I have a second control that closes the grapple teeth.So, I only have to connect one set of fittings, because the FEL movements are still there.Oh, and Skeptic has her work cut out trying to finish the silly painting (the welding was the fun part).   Has anyone used POR 15 paint?  I am getting ready to try it out here tomorrow.Skeptic
Reply:I agree about the painting- It't a bummer but necessary.  I've been using spray can primer and paint but it is so soft.  Haven't used POR, but I've heard good things about it.  I plan to start using it when I get a HVLP gravity gun, which will hopefully make cleaning easier.Please post the files when you get a chance.  Sorry about the gender screwup.Pat
Reply:POR 15 is vastly overpriced, and performence rarely meets expectations.Appreciation Gains You Recognition-I have used POR15 before, sticks to rusty metal well, but not to paint or primer.  It also degrades in sunlight if not topcoated.  Overall, overpriced for the performance.I recommend using enamel (Like rustoleum), but add hardener to the enamel to increase its durability.  The enamel hardener is available at my local farm store (fleet farm).
Reply:Skeptic has HER work cut out for HER?????????????? Let's see, she welds, lives in the country, has a John Deere...........Are you taken???????ME ME ME ME ME ME ME !!!!!!!!!!!!!!!!!!!Hell, I'm impressed!Low speed, high drag............but heavily armed!
Reply:Sticky...that is a very nice attachment you are building...I'm looking to do the same on my JD 3320 FEL, I sure would love to see some pics of the design or any other info on that.  Thanks.
Reply:Wow, that thing is cool!  Makes me wanna see it crush something... like a small car... maybe a Prius or something!   It looks hungry!  Nice job.Work HARDER, not smarter! ------------------------ Miller Bobcat 250Millermatic 251Lincoln Precision TIG 185Hypertherm PM 600Hobart 135 HandlerOxweld 400 FlameMaster
